Industry kiln control system
Abstract：With the development of industrial control automation technology, the computer automatically control in modern manufacturing is increasingly important in solving problem of production efficiency and consistency. China's industrial control automation technology has been greatly developed, which is developing toward intelligent, networked and integrated direction. Kiln is a high-temperature and high-risk industry, whose operators will run a higher risk in the field. Automation control can greatly reduce the risk. With stable and efficient performance, the tunnel kiln becomes a kind of important firing equipment in the production of refractory materials. Achieving automatic control of the tunnel kiln can greatly improve production efficiency and reduce labor intensity.
In this paper, analyzing the structure and work principle of the tunnel kiln, a strong set of feasibility the tunnel kiln automation control program is developed. The production process control method, kiln production safety protection measures and temperature control are taken into consideration during the research and design.
The design was implemented in a tunnel kiln. The tunnel kiln’s main firing product is ceramics, using coal as the fuel, whose maximum firing temperature is 1300 ° C. Controllers are Siemens S7-200 PLC and intelligent instrument-based. The temperature and pressure of the Tunnel kiln is controlled by PID automatic control system. The automation control of Tunnel kiln was achieved.
