The austenitizing furnace is a continuous unit, capable of treating 60 beams (roughly equivalent to 17 tons of steel) per hour. It has an operating temperature of 1670°F (910°C), and a maximum temperature of 2010°F (1100°C). There are 10 automatic control zones, designed to promote temperature uniformity.

There are 29 high-velocity burners, sited above the load. These allow for low NOx emissions, featuring stable high excess air and excess fuel operation, direct spark ignition, integral air and gas meters, sturdy cast construction and flame rod ionization. The burner configuration creates gas recirculation and allows uniform heating of the load and better heat transfer to the product through radiation mechanisms and convection.

The furnace employs NUTEC Bickley’s IMPS™ combustion system for energy savings, enhanced process control, optimal kinetic energy utilization from burners, temperature uniformity without excess air, a high turndown ratio, and other key benefits.

The tempering furnace — capable of heat treating beams at a rate of 60 pieces per hour — has an operating temperature of 915°F (490°C) and a maximum temperature of 1110°F (600°C). There are six automatic control zones and the heating method for tempering is via air circulation with a vertical flow pattern, ceiling to floor with six centrifugal fans.

Both of these furnaces benefit from insulation based on the patented Jointless® ceramic fiber system that allows fast heating and cooling and reduces heat storage. Using MacroModules, this insulation is 8 in (20 cm) thick in the combustion zones. Thermal efficiency has also been guaranteed with a specifically design of the door frame and canopy for both access and exit doors. Both furnaces are fully NFPA 86 compliant.

Heat Treat Operations Modernize with 9 Hardening Furnaces

/ HARDENING NEWS, MANUFACTURING HEAT TREAT NEWS, TEMPERING NEWS, VACUUM FURNACES NEWS

Nine heat treat furnaces are set to modernize the operations of a manufacturer’s heat treat facilities. This move is intended to create cleaner, safer, more cost-effective operations while also allowing for finer process control and a reduced carbon footprint.

The nine furnaces are being fabricated by SECO/VACUUM, a division of SECO/WARWICK Group: three Vector® vacuum furnaces and six tempering furnaces with supporting auxiliary systems. This returning heat treat client currently operates twelve SECO/VACUUM furnaces at their various locations throughout North America. They will incorporate the new furnaces as a continuation of their strategic planning to modernize all facilities from atmospheric heat treatment to vacuum processes.

Each of the nine units are front-loading, horizontally configured furnaces with a 36″ x 36″ x 48″ working volume and a 3300 lb. capacity. The Vector® is a single-chamber gas quenching vacuum furnace using high pressure quench (2 to 25 bar) which can be applied to a variety of heat treating processes and applications. These particular Vectors will be used primarily for hardening. Tempering is a process primarily used to increase the toughness of hardened ferrous-alloy parts. The tempering process is typically applied after a hardening process.

Heat treating operations will have to shut down entirely during the modernization changeover. To minimize disruption, SECO/VACUUM will also serve as the general contractor, overseeing the installation of the new furnaces, auxiliary systems, wiring, piping, and ventilation needed prior to commissioning and operator training.

“It is a testament to our commitment to our partner’s success that they not only continue to return for more furnaces, but that they place their trust us in to manage the entire project in order to get them back to serving their customers,” said Piotr Zawistowski, managing director at SECO/VACUUM.
