Muaj peb qho laj thawj vim li cas cov electrode poob qis thaum cov pa roj carbon hlau ferrochrome tsim tau
Coob tus neeg muaj qee qhov kev nkag siab ntawm cov pa roj carbon ntau ferrochrome, tab sis vim tias tsis koom nrog kev lag luam no, yog li cov txheej txheem ntawm smelting tsis nkag siab heev, tshwj xeeb tshaj yog cov pa roj carbon ntau yog vim li cas ho txo cov electrode thaum lub sijhawm hlau, thaum lub sijhawm smelting siab cov pa roj carbon monoxide ferrochrome, lub sijhawm tapping li kaum rau nees nkaum feeb, yog tias cov txheej txheem tapping kom nkag siab lub sijhawm, tsis tsuas tuaj yeem txo qhov kub ntawm lub cub tawg hauv qab, tseem yuav txo lub sijhawm ntawm smelting siab carbon ferrochrome, kom paub tseeb tias qhov tapping ntawm lub sijhawm, yog li yuav poob electrode, tee electrode muaj peb yam hauv qab no hauv kev nthuav dav.
1. Tom qab qhib lub qhov hluav taws xob tawm ntawm cov hlau, thaum cov hlau molten maj mam tawm, qhov kev ncua deb ntawm cov hlau electrode thiab cov nplaim molten hauv sab hauv pob txha taub hau yuav nce, qhov tawm tsam yuav nce ntxiv, thiab cov electrode yuav txo qis. Qhov no yog qhov tsim nyog rau cov tshuaj yej qis ntawm cov electrode, yog li tsim cov kev mob siab rau nthuav dav crucible kom nce qhov cub ua kom sov ntawm tus choj.
2, hluav taws xob arc kom tso tawm cov hluav taws xob, muaj lub dav hlau siab, qhov ntau ntawm cov electrode poob, nws lub siab ntau dua, tseem tuaj yeem siv lub sijhawm no los txhawb cov hlau nrawm dua, luv lub sijhawm hlau.
3, raws li cov hlau, tus crucible yuav qeeb qeeb, yuav ua rau qeeb ntawm electrode los tiv thaiv kev vau, ib zaug kev ua haujlwm tsis zoo, tapping txheej txheem ntawm vau, yog li yuav ncua sijhawm hlau, raws li hlau molten tawm, yuav tsum kom poob rau hauv qab, saum ntawm tus crucible yuav maj mam qis qis, lub sijhawm no ntawm lub electrode yuav maj mam poob, tsawg dua lub sijhawm yog yuam tawm ntawm hlau.
