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.

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).

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.

The annealing plant consists of several furnaces which are operated individually and a central charging system. From the central charging and discharging station, the coils are transferred to the individual furnace chambers. In individual coil heat treatment, each coil is annealed to obtain precisely the characteristics required by the customer.
All furnace functions and handling operations are fully automated.
