Graphite Electrode Factors hauv Steelmaking
Hauv kev lag luam steelmaking, cov txheej txheem hluav taws xob Arc rauv (EAF) yog ib txoj hauv kev siv ntau tshaj plaws. Xaiv txoj cai graphite electrode yog qhov tseem ceeb rau txoj haujlwm no. RP (Regular Power) graphite electrodes yog qhov kev xaiv nrov vim lawv pheej yig thiab tsim nyog rau kev ua haujlwm nruab nrab ntawm lub tshuab hluav taws xob.
Thaum xaiv RP graphite electrodes, muaj ntau yam tseem ceeb los xav txog. Ib qho yog cov electrode txoj kab uas hla, uas yuav tsum tsim nyog rau qhov tshwj xeeb qhov cub qhov loj thiab qhov yuav tsum tau ua. Qib ntawm cov electrode yog lwm yam; RP graphite electrodes feem ntau muab faib ua plaub qib raws li lawv cov hluav taws xob tiv taus thiab flexural zog. Qib tsim nyog yuav tsum raug xaiv raws li cov kev cai tshwj xeeb ntawm kev ua haujlwm ntawm lub cub tawg.
