The trolley tempering equipment consists of a furnace body and an electronically controlled two parts. The furnace section mainly includes the furnace shell, furnace lining, heating elements, furnace doors and trolleys. The furnace shell is welded by steel plate and steel. The furnace lining adopts energy-saving ultra-lightweight firebrick, aluminum silicate fiber and high-quality insulation material to form a composite lining. The heating element is wound with a high alloy resistance wire (or tape) spirally placed on the lining and on the trolley brick; the trolley can move back and forth to facilitate loading and unloading, and the novel automatic sealing between the furnace shell and the furnace shell is improved. Sealing performance; the lifting and lowering of the door and the trolley are driven by the electric deceleration mechanism; the bottom plate of the furnace is a heat-resistant steel casting, and the tilting unloading mechanism of the trolley is optional. The electronic control part mainly includes temperature control and operation. The temperature control adopts intelligent microcomputer program to control the temperature, and it is equipped with a recorder to record the complete process curve, and can be over-temperature alarm; the operation adopts the button plus light display to realize the control of the movement of the trolley, the on and off of the heating element, and the lifting and lowering of the furnace door. , And with interlocking devices, when the furnace door is raised or closed to a certain position, the trolley can be operated, safe and reliable!
Trolley return furnace equipment----temperature control system
The temperature control system consists of a thermocouple, an intelligent temperature control instrument, a solid state relay, and a power meter.
With K type thermocouple, the temperature range is 0-1100°C, and the thermocouple is connected with intelligent temperature control instrument to achieve PID adjustment, realizing the time monitoring and over-temperature alarm work. The temperature control instrument has a display panel. Through reasonable programming and parameter setting of the intelligent control instrument, the temperature and temperature correction can be set to achieve the best control of the furnace temperature zone, and the automatic temperature control can be used to achieve a better temperature stability. .
The electrical control system can be divided into two parts: the main heating power loop and the control loop. The design of the electrical part has the following features:
The trolley tempering equipment accessories are all made by well-known manufacturers at home and abroad, with high control accuracy, high degree of automation, stable performance, easy installation and commissioning, safe and reliable.
Temperature control instrument adopts PID regulator, this instrument has simple operation, perfect basic functions, four large LED display, self-tuning PID parameters.
