Kev siv cov ntaub ntawv graphite
(1) Rau hluav taws xob arc steelmaking rauv
Hluav taws xob rauv taws ua kom sov steelmaking yog tus neeg siv loj ntawm graphite electrodes. Tuam Tshoj tus hluav taws xob ua hluav taws xob tso zis hluav taws xob tso tawm kwv yees li 18% ntawm cov lag luam tawm hlau, thiab graphite electrodes rau steelmaking nyiaj rau 70% rau 80% ntawm tag nrho cov nyiaj ntawm graphite electrodes. Lub tshuab hluav taws xob ua kom sov cov hlau ua hluav taws xob siv hluav taws xob graphite electrode los qhia tam sim no rau hauv lub tshuab ua kom sov, thiab siv hluav taws xob kub ua kom muaj qhov hluav taws xob los ntawm qhov hluav taws xob ntawm qhov hluav taws xob kawg thiab lub txim kom ua cov smelting.
(2) Rau cov ntxhia cua kub ua hluav taws xob cua sov
Cov ntxhia thermal hluav taws xob ua kom sov yog siv rau kev tsim cov tshuab silicon thiab cov phosphorus daj, uas yog tus cwj pwm hauv qhov tias qhov qis ntawm qhov hluav taws xob conductive tau muab faus rau hauv lub txim, ib qho arc tsim nyob rau hauv txheej, thiab cov cua sov yog tsim los ntawm lub tshav kub uas tsim los ntawm kev tawm tsam ntawm nws tus kheej, uas yuav tsum tau siv Graphite electrodes tam sim no yuav tsum tau siv rau qhov kub siab me me rau cov hluav taws xob cua sov. Piv txwv, kwv yees li 100 kg ntawm graphite electrodes yog noj rau txhua 1t ntawm silicon tsim, thiab kwv yees li 40 kg ntawm graphite electrodes tau noj rau txhua 1t ntawm daj phosphorus.
(3) Rau ua haujlwm rauv taws ua kom sov
Cov khoom tsim muaj graphite rau kev tsim cov khoom lag luam graphite, nplaim taws ua kom sov rau iav melting, thiab hluav taws xob rau qhov ua kom muaj cov khoom siv silicon carbide yog txhua qhov chaw tiv thaiv. Cov ntaub ntawv muaj nyob rau hauv lub tshuab ua kom sov yog ob qho tib si ua cua sov thiab cov khoom ua kom sov taus. Feem ntau, graphite electrodes rau conduction tau kos rau hauv qhov cub hluav taws xob tsis kam Ua rau ntawm phab ntsa hearth ntawm qhov chaw nruab nrab, graphite electrode siv ntawm no tau txiav pov tseg.
(4) Rau kev tsim cov khoom ua duab graphite
Cov graphite electrode dawb paug tseem siv los ua cov khoom lag luam muaj cov duab graphite xws li ntsia, pwm, nkoj thiab cua sov hais. Piv txwv, hauv kev lag luam quartz iav, graphite electrode blanks xav tau siv rau 10t rau txhua 1t ntawm electrofusion leeg; 100kg ntawm graphite electrode blanks xav tau rau txhua 1t ntawm quartz cib.
