6、Structural characteristics of Roller bottom quenching and tempering heat treatment furnace

The Roller bottom quenching and tempering heat treatment furnace structure is introduced as follows:

1. Waste heat recovery system

Used to recover the exhaust heat of the heating furnace. There are two kinds of recovery methods, one is to recover by preheating combustion air, so that the recovered heat can return to the furnace again; The other is to use another recovery system to recover heat. The former is called air preheating mode, and the latter is usually called waste heat boiler mode.

2. Radiation chamber

The heat load of the main place for Roller bottom quenching and tempering heat treatment furnace heat exchange accounts for about 70%-80% of the whole furnace. The furnace tube in the radiation room conducts heat through flame or high-temperature flue gas, which is mainly radiant heat, so it is called radiation tube.
