The temperature control system of natural gas high temperature trolley furnace is mainly composed of four parts: temperature sensor, temperature regulator, actuator and controlled object. The controlled object is the temperature object of natural gas trolley furnace with large capacity and inertia. Because the controlled object has large capacitance, SCR is usually used as the actuator of the regulator:

 

1. The temperature control system of natural gas trolley furnace adopts computer temperature controller, which is suitable for trolley type tempering, quenching, normalizing, annealing and other heat treatment processes;

 

2. The temperature control system is made of two-way silicon controlled material, and the temperature controller without contact connection is accurate and stable.

 

3. The system is equipped with paperless recorder, which is convenient for centralized management of staff and real-time monitoring of process data;

 

4. The temperature control system has high accuracy;

 

5. The temperature control system has a comprehensive safety device, including temperature control alarm light, automatic limiter and other functions;

 

6. Characteristics of the actuator: the temperature regulation of the natural gas trolley furnace is to control the temperature rise and fall of the natural gas trolley furnace through the intermittent action of the regulator.
