A rod overbend box furnace with powered load/unload table is being shipped from Michigan to a manufacturer. An automated actuator increases safety measures protecting the operator.

Lindberg/MPH's furnace has a maximum temperature rating of 2,000°F and a load capacity of 900 lbs. The workspace dimensions of the furnace are 24” x 36” x 18” and is designed for air atmosphere applications. The box furnace features an automated actuator to flip the push/pull mechanism on the load table to eliminate the operators need to manually flip it into push position. This option allows the push/pull head to retract from the furnace once the work grid is in the furnace chamber and increases operator safety by removing the need to reach into the hot furnace with a hook to flip the push/pull head.

“This furnace design is a duplicate to a previous order . . . . with the [requested] modification of an automated actuator to provide easier loading for the operator," commented Bill St. Thomas, business development manager at Lindberg/MPH.

HTD Size-PR Logo

Full-service commercial heat treating solutions provider Akademi Metalurji incorporated a turnkey nitriding installation to save on process gases and production time, and also process wider-dimensioned parts.

The project includes a mid-sized pit-type furnace, advanced controls, three process technologies, and accelerated cooling. The latter add-on equipment will help reduce cycle times, optimize production between batches, and run more cycles.

This new system allows the company to overcome efficiency and quality challenges they faced at the Gebze, Turkey, facility; the prior system consumed excessive amounts of process gases and yielded inconsistent nitriding results. Nitrex, a Canada-based company with international locations, provided the NX-1015 pit furnace, which offers an effective work zone of 39” d x 59” h (1000 x 1500 mm) and a load capacity of 4400 lbs. (2000 kg). The supplied library of Nitreg®-based recipes is tailored to meet different application requirements, resulting in a hardened surface that is highly wear-resistant, particularly useful for applications like machinery components, tooling, dies, and molds, where Akademi Metalurji specializes.

The system was successfully installed and commenced operations in April 2023.

HTD Size-PR Logo

PWR Advanced Cooling Technology has ordered two universal batch CAB furnaces and a CAB continuous line. The furnaces will be used for brazing aluminum heat exchangers. The 3 solutions will go to 2 continents – Australia and North America.

PWR Advanced Cooling Technology specializes in the production of modern and efficient heat exchangers and has used SECO/WARWICK Group furnaces in the past. Two furnaces, the continuous CAB line and Universal Batch CAB Furnace, will be delivered to production plants in Australia. The second chamber furnace will be delivered at the same time to the American branch of PWR, C&R Racing Inc.

The universal batch CAB furnace meets the requirements for protective atmosphere aluminum brazing technology (Nocolok®) and allows users to braze products in a horizontal or vertical position.  The continuous CAB line performs brazing in a protective atmosphere for mass production of various heat exchangers.

“We have already ordered the company’s furnaces twice, and the current contract, although more than 25 years have passed since the first order, is the best proof that we are satisfied with the product quality, cooperation, and after-sales service.” said Andi Scott from PWR Advanced Cooling Technology.

“The current contract is special because we will deliver different solutions simultaneously to two continents but to the same customer,” commented Sławomir Woźniak, CEO of the SECO/WARWICK Group.

Derek Dennis
President
Solar Atmospheres California

Solar Atmospheres of California (SCA) installed a new 14 foot long car bottom air furnace. With a maximum operating temperature of 1450°F, this furnace tempers large tool steel components, age hardens 15-5 PH, 17-4 PH, 13-8PH and nickel-based alloys, and anneals titanium forgings.

SCA is typically known around the world as a “vacuum only” heat treater. However, there is a great need for heat treating non finished parts and materials in accordance with the same specifications (AMS, MIL, Boeing, and Airbus) within different atmospheres where surface oxidation is permissible. This furnace allows for a “raw material” option.

“Solar Atmospheres of California is excited to be adding this new furnace and the added capability/capacity," stated Derek Dennis, president of SCA. The furnace has a working zone that is 60" square by 168" long with a total load capacity of up to 30,000 pounds.

A front-loading box furnace delivered to a northeastern U.S. supplier of titanium castings will expand the manufacturer’s aerospace and gas turbine castings heat treat abilities. The company supplies to the aerospace and power generation fields and deals with exotic metals that are ideal for superior products using the lost wax process for castings, such as nickel and cobalt-based alloys.

The L&L Special Furnace Co., Inc. model FB435 has an effective work area of 48” wide by 32” tall by 60” deep and has certifiable temperature uniformity of ±10°F from 500 to 1,850°F. Additionally, the elements are very evenly spaced around the chamber and the furnace is lined with ceramic fiber on the sides and top.

The furnace case is sealed internally for atmosphere control, and an inert blanketing gas such as nitrogen is used to displace oxygen present within the work chamber. This provides a surface finish in which oxidization is less likely to form on the part. The atmosphere is delivered automatically through a flow panel by the furnace control.

Tool Manufacturer To Expand Heat Treat Capabilities with Pit Furnace

/ ATMOSPHERE AIR FURNACES NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT

HTD Size-PR Logo

A tooling manufacturer is expanding with an electrically heated, steam atmosphere pit furnace for steam treating parts. The steam treating process creates a uniform blue-black finish on the surface of parts, which improves wear and corrosion resistance.

Lindberg/MPH, a manufacturer based in Michigan, shipped the steam treating furnace which has a maximum temperature rating of 1,250°F and work chamber dimensions of 22" diameter x 36" depth. The pit furnace is insulated with vacuum formed ceramic fiber modules that allow for rapid heat up rates and fast control response. A circulation fan distributes heat evenly throughout the chamber which ensures rapid and uniform heat transfer throughout the product load.

“This steam atmosphere pit furnace has the sufficient capacity to process a workload of 1,200 lbs," comments Kelley Shreve, application engineering manager at Lindberg/MPH. "This furnace was also designed with a custom powered lid for ease of loading."

The SCAHT®-HD (Heavy Duty) Series furnaces, from DELTA H®, are set up with Instrumentation Type B and have two load thermocouples. The furnaces have a certified TUS volume of 2 feet wide, 1.5 feet high and 2 feet deep with a maximum continuous operating temperature of 1,200°F.  Both are designed to receive baskets of parts from many nearby heat treating operations for secondary heat treatments. Temperature control and data acquisition are provided by Super Systems and feature the SSi 9130 controller/programmer. ATP qualified them as Class 2 (+/- 10°F) from 300°F to 1200°F.

“We were looking for a partner to replace existing tempering furnaces that had become too costly to maintain and could no longer meet required pyrometry standards. Our goal was to install reliable and modern furnaces that were specialized for our small batch/job shop work," said David Reger, president at Winston Heat Treating and a Heat Treat Today's 40 Under 40 recipient.
