淬火炉安全操作规程Safe operation rules for quenching furnace一、开机前的准备Preparations before starting up1.关闭各控制柜门并检查门碰开关可靠有效；Close all control cabinet and check whether door touch switch is reliable and effective;2.检查控制面板指示灯完好；检查各接地线可靠连接。Check whether indicator light of control panel is in good condition; Check whether grounding wire is reliably connected. 二、开机作业Starting up operation将热电偶引线“+ -”接于仪表后部接线端。Connect the lead of thermocouple“+ -”with terminal located in the rear part of gauge.将电进线和输出线按接线图所示，接于控制器接线板上。Connect input line and output line with the wiring board of controller according to wiring diagram.调节调零器使指针位于“0”位。Adjust zero adjuster to make pointer stay“0”position.打开电源开关，将温设定调至所需温度。Turn on the power switch, and adjust the temperature to the desired temperature.打开温度控制器电源开关，绿灯亮，接触器吸合，电流表指示相应电流值，电热丝通电升温，指针向右偏转，达到温度值后，温度控制器自动切断电源，接触器断电，同时切断电热炉电源，绿灯灭、红灯亮，当炉温低于所需温度时，控制器自动接通电源，红灯灭，绿灯亮，进行升温，如此反复，自动调节炉内温度。Turn on the control switch of temperature. When the light turns green, contactor absorbs, and ampere meter indicates corresponding current value. Heater strip heats up and indicator turns to the right. Temperature controller cuts power off automatically after reaching certain temperature, and contactor suffers power failure. The power of electrothermal furnace is off at the same time. Green light goes off, and red light goes on. When the furnace temperature is blow desired temperature, red light goes off, green light goes on. Furnace temperature is adjusted automatically.使用电炉，切记超过最高温度。It is forbidden to exceed maximum temperature when workers use electric furnace.三、保养maintenance 不经允许，不可移动设备。It is forbidden to move equipment without permission. 要保持场地干净。Keep the site neat and tidy. 作好设备及工作场地的整理、整顿、清扫、清洁。Keep 5S standard in the work site an
