1、淬火爐安全操作規(guī)程Safe operation rules for quenching furnace一、開機前的準(zhǔn)備Preparations before starting up1.關(guān)閉各控制柜門并檢查門碰開關(guān)可靠有效；Close all control cabinet and check whether door touch switch is reliable and effective;2.檢查控制面板指示燈完好；檢查各接地線可靠連接。Check whether indicator light of control panel is in good condition; Check w

2、hether grounding wire is reliably connected. 二、開機作業(yè)Starting up operation將熱電偶引線“+ -”接于儀表后部接線端。Connect the lead of thermocouple“+ -”with terminal located in the rear part of gauge.將電進線和輸出線按接線圖所示，接于控制器接線板上。Connect input line and output line with the wiring board of controller according to wiring diagra

3、m.調(diào)節(jié)調(diào)零器使指針位于“0”位。Adjust zero adjuster to make pointer stay“0”position.打開電源開關(guān)，將溫設(shè)定調(diào)至所需溫度。Turn on the power switch, and adjust the temperature to the desired temperature.打開溫度控制器電源開關(guān)，綠燈亮，接觸器吸合，電流表指示相應(yīng)電流值，電熱絲通電升溫，指針向右偏轉(zhuǎn)，達到溫度值后，溫度控制器自動切斷電源，接觸器斷電，同時切斷電熱爐電源，綠燈滅、紅燈亮，當(dāng)爐溫低于所需溫度時，控制器自動接通電源，紅燈滅，綠燈亮，進行升溫，如此反復(fù)，自動

4、調(diào)節(jié)爐內(nèi)溫度。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

5、 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.使用電爐，切記超過最高溫度。It is forbidden to exceed maximum temperature when workers use electric furnace.三、保養(yǎng)maintenance 不經(jīng)允許，不可移動設(shè)備。It is forbidden to move equipment without permission. 要保持場地干凈。Keep the site neat and tidy. 作好設(shè)備及工作場地的整理、整頓、清掃、清潔。Keep 5S standard in the work site an
