A provider in the power solutions industry has enhanced its operations with a heat treat drop-bottom furnace for the solution heat treatment of aluminum castings. This installation will increase the company’s production capabilities, with the furnace having a load setting of 48 in (123 cm) wide x 36 in (91 cm) high x 141 in (358 cm) long.
The furnace, the fifth designed and manufactured by NUTEC Bickley, has a single temperature control zone, typically operating at 1000°F (573°C), with a maximum of 1075°F (580°C). The load setting will accommodate up to three baskets, equivalent to around 3600 lb (1635 kg) of aluminum parts per cycle. The furnace has been customized to be indirect gas-fired using radiant tube burners. Additionally, the project incorporates a motorized quench tank, rails, movement system, and load/unload platform with elevator device.
Arturo Arechavaleta Vice President, Metal Furnaces NUTEC Bickley
“Efficient and effective solution heat treatment is a vital part of the aluminum casting process,” said Arturo Arechavaleta, vice-president of Metal Furnaces at NUTEC Bickley. “Without the sort of advanced system that we have custom-designed, volume production of high-quality aluminum parts is not feasible. We’re proud to have played an important role in this technology partnership.”
The indirect gas firing is via single centrifugal recirculation that produces a vertical flow pattern. Heating is achieved with four radiant tube burners that have individual flame safety devices. The burner system incorporates a motorized control butterfly valve, and the gas flow is controlled by proportional ratio regulators. This design, with its baffle arrangement, delivers an even flow pattern, providing excellent temperature distribution and control in the furnace’s load chamber and high-efficiency heat recirculation (convection) horizontally across the aluminum castings. Excellent temperature uniformity was always considered an important parameter, and this has been shown to be ±5.4°F (±3°C) under full test in the provider’s manufacturing facility.
In order to maintain excellent thermal efficiency in operation, the furnace walls are fully lined using ultra large proprietary ceramic fiber modules. Their configuration and fixing provide for excellent insulation and long life coupled with low maintenance. The insulation layer is 6 in (150 mm) thick and has a density of 12 lb/ft3 (192 kg/m3).
The installation will see the drop-bottom furnace itself stationary — in a fixed elevated position — with the quench tank and loading car moving to accommodate baskets at the selected position. The furnace has a single, pneumatically operated horizontal slide door. For these particular aluminum castings, the company will employ a motorized water quench system provided by NUTEC Bickley, as well as its rails included leveling and installation. The tank has been designed to accept a full load of pieces within the work basket when the furnace is positioned vertically above it.

Are you looking to expand in-house heat treat operations on a brownfield industrial site? These sites can bring complications due to a more restrictive footprint combined with other fixed process conditions. In today’s Technical Tuesday installment, the authors of this case study reveal how to consider available footprint and conveyance mechanism options in a continuous steel reheat furnace, as well as the key design variables for industrial furnaces.
On the research team are the following: Michael K. Klauck, P.Eng., President; Robin D. Young, P.Eng., Vice President — Mechanical Engineering; Gerard Stroeder, P.Eng., Manager — Sr. Technology Specialist; and Jesse Marcil, E.I.E., Project Manager — Mechanical Engineering, all from CAN-ENG Furnaces International.
A manufacturer with in-house heat treating had the need to develop a custom furnace for a critical step in the forging process. Specifically, this furnace would be for reheating bottom poured ingots and/or continuously cast round blooms to forging temperatures.
Like all industrial furnaces, the design for such a furnace takes into consideration many factors, including but not limited to:
Production throughput/capacity
Product configuration/condition
Material composition
Target product temperature uniformity
Soak time
Cycle time
Serviceability
Upstream and downstream process integration
Automation
Continuous reheat furnaces that supply steel rolling mills (slabs, blooms) are often designed for very large capacities up to 500 TPH (tons per hour). However, this client’s site was in the 15–30 TPH capacity range. For an open die forging application, this would be considered a low to medium capacity range.
Another consideration was that this was a location with already existing buildings. “Greenfield” sites are undeveloped areas free from prior industrial use; thus, they impose very few restrictions on the layout of the reheating furnace and overall forging cell. In this case, the manufacturer was developing on a “brownfield,” a place with evidence of prior industrial production. Places like these often have the blessing and curse of existing, vacant structures. So, in addition to the design considerations listed above, the physical limitations of a brownfield places constraints on what technology can meet the key performance deliverables.
In this article, we will review how this manufacturer with in-house heat treat was able to customize their furnace to successfully adapt it to the constraints of a brownfield location. The key: An appropriate conveyance mechanism.
Figure 1. Traditional gantry style loader/unloader
Continuous Furnace Design for Cylindrical Round Reheating
The client’s product was a cylindrical “as cast” (continuous casting or static cast) round of approximate weight 1.5–2 tons with required reheating at 2300°F. With a design production capacity of 15–30 TPH, batch reheating was not a viable option; the main choices for continuous furnace reheating are either a walking hearth or rotary hearth furnace (“ring furnace”).
The scope of plant equipment that had to be installed in custom forging cells consists of the following:
Incoming raw material preparation and cutting
Reheat prior to forging
Forging
Post-forging operations — trimming, shearing, and heat treatment (normalizing, tempering)
Machining and finished goods
For a recent reference site, the incoming raw material preparation, the cutting facility consumed approximately 30% of the overall floor space and the forging machine consumed 35% of the footprint, leaving approximately 35% of the available area for the reheating furnace. A comparison of the advantages and disadvantages of the walking hearth technology and rotary hearth technology was made and presented to the end user.
Some of the advantages of the rotary hearth design included the following:
A smaller overall footprint/lower consumption of building length
Non-water-cooled hearth
Positive product positioning with low risk for movement during conveyance
No complicated pits/foundations
Less complicated drive system
Figure 2. Wrought round bar discharge via a single door system
For this reason, the end user opted for the rotary hearth furnace design over the walking hearth system. A traditional rotary hearth furnace design incorporates two gantry style units, one for loading and one for unloading (see Figure 1). There is a “dead zone” of 10–20° between the charge and discharge which does not contribute to the overall effective heated length.
Alternatively, the CAN-ENG design employs a single door vestibule for both charging and discharging. Instead of dedicated mechanical systems with limited degrees of freedom, this design uses a pedestal-mounted, purpose-built furnace tending robot with a 270° axis slew (see lead article image). The result of these design changes is a more effective utilization of the building width for reheating with no dead zone combined with a robot that has considerable freedom when transferring products from furnace elevation to discharge conveyor elevation.
The robotic feature is particularly important when considering pass line differences for various pieces of equipment in a production cell. Some installations cannot have pits due to high water table considerations, and so the flexibility of robot reach combined with the 270° of axis slew yields fewer restrictions for the end user.
Figure 3. Plan view product layout showing inner and outer charge positions
This rotary hearth furnace can be configured for loading a single long piece or two shorter pieces, one charged towards the furnace inner ring, and one charged to the furnace outer ring, with a suitable gap between the pieces and the refractory walls. This provides considerable flexibility for piece size which is accommodated by the furnace tending robot. Had gantry style loaders/unloaders been used for the charging/discharging functions, the requirement for charging an inner and outer ring of the furnace would have been significantly more challenging.
The overall diameter of a typical steel rotary furnace for 15–30 TPH of production capacity is in the 55’–65’ diameter range (outside of steel service platform). This is dependent on the soak time specified by the end user and the heat up time for the cast or wrought steel product that is charged.
There are many aspects of industrial furnace design that are not covered in this article, and they would include at a minimum:
Refractory — hearth, wall, roof and flue areas
Flue design
Burner type — heat-up zones (both above and below auto-ignition), holding zones (i.e. soak zones
Physical zone separation vs. soft zoning
Drive configuration/drive synchronization
MES or Level II automation and controls
Incoming raw material cutting — carbide-blade, band saw and torch
A full article could be dedicated to each of these subjects. Many details are considered confidential design aspects of the furnace builder.
To speak just on support pieces (piers/bunks), nearly all refractory pier compositions are subject to interaction between the scale that is formed during heating (Fe2O3/Fe3O4) and silicates in the refractory matrix, particularly at reheating temperatures of 2300°F or higher.
Under the conditions of pressure and extremely high temperatures, a low melting point liquid compound of fayalite (iron silicates) is formed at the contact point between the workpiece and refractory pier. This is very undesirable and severely limits the overall pier life. Nickel- and cobalt based super alloys have been used successfully at temperatures up to 2450°F, but these materials can be cost prohibitive, especially considering that 70 or more product locations/pier placements may be required. Unless the product requires very restrictive uniformity in reheating (i.e., titanium ingots), consideration of nickel- or cobalt-based work support pieces is not economically feasible.
Figure 4. 3D rendering of a CAN-ENG single door rotary hearth furnace
The most important consideration for the forging cell downstream of the reheating furnace is the uniformity of the bar, ingot, bloom or mult as delivered for forging. Accurate determination of the temperature uniformity is often misleading by infrared radiation (IR) methods since primary scale is removed in the breakdown passes and secondary scale reforms in its place. Workpiece thermocouple measurements at defined locations in predrilled test pieces under full load conditions yield the best results for determining product uniformity prior to furnace discharge.
Conclusion
The modern rotary hearth ring furnace at low to medium production capacities of 15–30 TPH offers a compact footprint that has many advantages compared to water cooled beam walking hearth type reheating furnaces. This is particularly important to brownfield sites which need to adapt the existing industrial layout to current production needs. When combined with automated saw cutting and forging cells, an integrated manufacturing solution results in very low man-hour/ton of labor input. As seen in this article, recent reference sites where material handling conveyors, robots, descale units, vision systems and Level II MES (Manufacturing Execution Systems) were supplied have allowed U.S.-based end users to achieve the lowest total production costs, allowing them to be competitive with India and China.

A manufacturer which supplies agricultural ground engaging solutions has improved its production efficiency with two roller hearth furnace systems. The furnaces will be used to re-heat flat stock for hot forming, replacing existing equipment as part of a plant modernization initiative at its locations in both the United States and Canada.
The company commissioned the two 8000 lb/hr, high-temperature re-heat furnaces lines from CAN-ENG Furnaces International Limited (CAN-ENG) to heat steel plates to temperatures suitable for hotworking, where pieces are formed by a hydraulic press. The Ontario-based heat treating equipment provider designed the fully automated system to reduce energy consumption and floor space, while improving product flow and maintaining high-throughput requirements.
Scott Cummings Sales Manager CAN-ENG Furnaces International Limited
Each furnace is capable of operating up to 1750F and producing a part ready for forming every 15 seconds. The former equipment required alloy fixtures that consumed additional energy to heat up each time along with the product as well as costly periodic replacement and maintenance, heating the product directly on the furnace rolls increases the efficiency and reduces the overall equipment size.
“Can-Eng was selected as the supplier for this project based on our vast experience with high temperature roller hearth furnace systems and Can-Eng’s reputation to stand behind our equipment,” said Scott Cummings, sales manager for CAN-ENG.
