Car Bottom/Bogie Hearth Furnace

Heating stage:
The trolley sends the metal material to be processed into the furnace. The burner or electric furnace on the upper part of the furnace will produce high-temperature flame or electric heat energy, which will be radiated and conducted to the metal material and raise to the required processing temperature.

Insulation stage:
When the metal material reaches the processing temperature, a constant temperature will be maintained in the furnace, allowing the metal material to perform the required heat treatment processes at this temperature, such as annealing, sintering, quenching, etc.

Cooling phase:
After the heat treatment process, the supply of the heating source in the furnace will be stopped and the temperature in the furnace will gradually drop. In order to prevent metal materials from generating stress and deforming if the metal material cooled too quickly, two cooling methods can be used. One is natural cooling, left the metal material in the furnace and cool down statically. The second is to use external cooling media, such as air, water or oil.
