CHAMBER TYPE REHEATING AND HEAT TREATMENT FURNACES
Wesman has built a large number of fuel fired and electrically heated Chamber furnaces for reheating and heat treatment applications in past five decades. Wesman has a full range of Chamber type Reheating and Heat Treatment Furnaces to offer to Steel Mills, Heavy Structurals, Forgings, Foundry Cast House, and other metal industries with temperature range of 200 deg C to 1350 deg C. These furnaces can be offered with vertical rise and fall type doors with electro-mechanical drive system. The material are loaded on the hearth of the chamber furnace with the help of manipulator/robot or manually with tongs depending on the size and weight of the material. After reheating/heat treatment operation, the material can be unloaded with the help of above machines. Chamber type furnace can also be offered with grooved hearth construction suitable for loading/unloading of material with the help of fork type hydraulically or electro-mechanically operated machine.
Fuel fired furnaces are provided with Wesman’s high efficiency burners supported by a full complement of combustion system consisting of combustion fan, atomizing fan, oil heating and pumping systems and/or gas trains. In addition auto ignition, flame failure safety and complete control systems are offered. Practically any type of liquid or gaseous fuel can be used viz. Furnace Oil, Light Diesel Oil, LPG, Natural Gas and Coke Oven gas singly or a combination of any oil or gas in case of dual fired furnaces.
The furnace can be provided with electrical heating through heat resistant Strip/Wire/Cartridge heating elements located along with the side/back walls/roof of the furnace. The heating elements of the furnace are suitably divided into number of heating zones with each zone of having their bank of heater. The heating elements of the furnace are suitably divided into number of heating zones and can be controlled through Contactor or Thyrister based control philosophy through PID controllers.
Wesman Chamber furnaces are lined with ceramic fibre modules/blankets or dense firebricks backed by insulation bricks on the side wall, roof and door and hearth of the furnace will be provided with combination of high/medium grade aluminium bricks backed-up by insulation bricks to minimize the skin temperature.
Wesman has full capability to offer complete control and instrumentation system through PLC based or hard-wire based logic controls.
