The key features of our Billet Homogenising are:
We can use multi-zone control for temperature, pressure and air circulation.
Multi fuel capability (gas or oil).
Use of self-recuperative gas burners with simple firing controls resulting in compact furnace mounted piping/ducting system.
Direct coupled, self cooling – recirculation fans for compact roof arrangements, invertor controlled for optimised speed control.
Double heat seal door reduce furnace heat losses
Gas tight explosion relief panels
Complete billet handling equipment, stacking equipment and charge/discharge car sub-supply and control integration.
Process control systems provided in PC/PLC based systems designed by our “in house” systems team, with continued development of the Solios Thermal predictive temperature model software reducing the requirement for load thermocouples.
Complete integrated exhaust systems including zone pressure control dampers.
Recipe based control systems allow various heating cycles to be chosen.
Forced air cooling chambers for rapid billet cooling.
Typical performance characteristics:
Reference Billet load – 150 mm diamater x 8 000 mm (10 billets high x 13 billets wide).
Heat to 590 Deg. C+/- 10 in 4.0 hours
Heat Head 620 Deg. C
Fuel usage (with gas heating) during homogenising 190 kWh/t and 12 kWh/t (Electrical for motors, instrumentation, etc..)
Homogenising - achievable Billet temperature uniformity +/- 3 Deg C.

Car Bottom Furnaces can be provided for annealing, normalizing and stress relieving bars, tubes, forgings, large weldments and castings and can be gas fired or electrically heated with either guillotine or bulk head doors. Sand or pneumatically operated mechanical car seals are available.
Tip-Up Furnaces are used where better atmosphere control and temperature uniformity are necessary. Alternate load/unload methods are available.
A Wellman direct gas fired Tip-Up Furnace with a car bottom hearth is shown below for normalizing alloy steel castings. This system combines the Tip-Up advantages of a tight seal and better temperature uniformity with the convenience of loading and unloading on a moveable car with a refractory hearth.

Wellman Furnaces, Inc. offers a complete line of Exothermic Gas Generators for rich and lean operation. Standard sizes range from 750 SCFH to 30,000 SCFH. Refrigerated Gas Coolers can be provided to reduce the product gas dewpoint to the 40°F to 50°F range. Atmosphere Gas Analysis Panels are available to monitor the exo gas composition and control an optional trim valve in the burner fuel gas line to maintain the desired CO analysis.
Wellman Exothermic Gas and Steam Co-Generators will give you the process atmosphere gas you need and the added benefit of Free Steam. Major savings in both fuel and cooling water can be realized by combining your exothermic gas generator and steam boiler into a single unit. Paybacks range from six months to two years - Returning Your Initial Investment!
Exo Gas and Steam Co-Generators are available in sizes from 4,000 to 100,000 SCFH of exothermic gas, producing 390 to 9,780 lb/hr of steam.
