基于西门子S7 400控制器平台,实现了不锈钢马弗炉的精确控制。采用双控制回路,准确控制了氢气和氮气的混合比例;使用PID调节确保了稳定的炉压;同时配置了露点监控功能,保证了不锈钢板的高品质。该控制系统投入后运行稳定,取得了良好的效果。
Based on the Siemens S7 400 controller platform, the stainless steel muffle furnace is precisely controlled. Dual control loop, accurate control of the mixing ratio of hydrogen and nitrogen; the use of PID regulator to ensure a stable furnace pressure; also configured dew point monitoring to ensure the high quality of stainless steel. The control system put into operation stable, and achieved good results.
