Electrical control system for long bar heating furnace

Abstract

The invention provides an electrical control system for a long bar heating furnace. The system comprises a transmission system, a heating system and a monitoring system, wherein the transmission system comprises a power cabinet, a tempering transmission cabinet, a quenching transmission cabinet, a position detector, a material position switching and water system and motors, wherein a transducer, a PLC and an operating device are arranged in the tempering transmission cabinet and sequentially connected; the transducer is connected with the corresponding motor; the heating system comprises a heating control cabinet and a heating furnace; the monitoring system comprises a simulating plate monitor, a touch screen integral monitor and a heating system monitor; the transmission system, the heating system and the monitoring system are connected through the PLC. According to the system, the heating, quenching and tempering of a workpiece can be automatically carried out; the workpiece heating time can be accurately controlled and adjusted, so that the operators can be greatly decreased, and the labor intensity can be reduced; meanwhile, an automatic production line of the long bar heating furnace can be monitored in real time and remotely diagnosed.

Description

technical field [0001] The invention relates to the field of electrical control, in particular to an electrical control system for a long rod heating furnace. Background technique [0002] The traditional long rod heating furnace control system has a lot of mechanical equipment in operation, and there is very little automatic control involved. As a result, the flexibility of the equipment is poor, and the adaptability to the processing of workpieces of different types and specifications is poor. Due to the characteristics of mechanical equipment, the function of rapid process switching cannot be realized. The original heating system lacks stability, high failure rate, many failure nodes, relatively simple control equipment, and the pass rate and precision of finished products are difficult to meet the increasing market requirements. Due to technical limitations, the production equipment requires large workpieces and fixed investment, and the production cost, labor cost and ...
