Application

The RT3-600-12 electric bogie hearth furnace is mainly used for annealing and solution heat treatment of steel structure parts, alloy parts and stainless steel parts, etc.

3. Structural Introduction

The RT3-600-12 bogie hearth heat treat furnace is mainly comprised of furnace shell,

lining, furnace door and door compression system, bogie, heating element

and fixed device, and temperature control system.

3.1 electrical control system

Temperature control: the temperature of each heating zone of the industrail metal furnace can be

controlled separately.

The furnace adopts intelligent temperature controller to control the temperature which has

self-tuning function to calculate the ideal PID parameter and achieve a temperature stability.

The temperature controller has the functions of over-temperature alarm and thermal couple

breakage protection.

The bogie hearth furnace has 4 temperature control zones for controlling the linkage between the

temperature and the motor movements. Each zone is set with an over-temperature alarm.

The heating loop adopts the double-direction SCR and trigger control. The power is regulated

in the time proportional regulation manner.

The control actuation system is a large-power triggering one complete with a radiator and an

air cooling system. There is also an air switch. The heating loop is equipped with ammeter,

voltmeter, heating element on-off indicator, power-on interlock protection, and safe earthing

measures.

Movement control: The control system mainly controls the door up-down movement, door

compression, and door in-out movement. Also the movements are necessarily linked to

ensure the operation safety.
