1. Ua ntej pib lub qhov cub, tshuaj xyuas cov khoom siv hluav taws xob, dej txias, thiab inductor tooj liab coils kom ntseeg tau tias lawv nyob hauv qhov zoo; txwv tsis pub ua lwm yam.
2. Kho lub tshuab hluav taws xob tam sim yog tias kev yaig ntau tshaj qhov txwv. Kev ua haujlwm melting yog nruj me ntsis txwv tsis pub nyob rau hauv crucibles nrog ntau txheej txheej erosion.
3. Fais fab mov thiab qhov cub pib yuav tsum tau tswj los ntawm cov neeg ua hauj lwm; kov lub inductor lossis cables tom qab siv hluav taws xob yog nruj me ntsis txwv. Cov neeg ua haujlwm ntawm lub luag haujlwm yuav tsum tsis txhob tawm ntawm lawv cov haujlwm yam tsis muaj kev tso cai thiab yuav tsum saib xyuas qhov xwm txheej ntawm inductor thiab sab nrauv ntawm lub crucible. Tsis tas li ntawd, xyuas kom meej tias cov kev saib xyuas thiab lub tswb nrov rau qhov nruab nrab -frequency furnace's cooling water outlet temperature and the flow rate different between inlet and outlet are functioning .
4. Thaum them nyiaj, tshuaj xyuas lub cub hluav taws xob rau cov khoom siv hluav taws xob, tawg, lossis cov khoom phom sij thiab tshem tawm tam sim ntawd. Tsis txhob ntxiv cov khoom txias lossis ntub dej ncaj qha rau hauv cov hlau molten. Thaum cov yaj mus txog rau sab sauv ntawm lub qhov cub, tsis txhob ntxiv cov khoom loj los tiv thaiv kev tsim ntawm cov khoom crust (bridging).
5. Tiv thaiv kom tsis txhob muaj kab mob los ntawm cov ntaub ntawv hlau lossis hlau oxide thaum lub sij hawm kho qhov cub hauv ob sab phlu lossis crucible ramming; xyuas kom lub crucible yog rammed mus rau ib tug siab ceev.
6. Khaws qhov chaw pouring thiab lub qhov taub nyob rau hauv pem hauv ntej ntawm lub cub tawg kom tsis txhob muaj kev cuam tshuam thiab sawv ntsug dej kom tsis txhob tawg los ntawm molten steel hu rau dej.
7. Tsis txhob overfill ladles nrog molten hlau. Thaum siv lub ladle phau ntawv, ob tus neeg ua haujlwm yuav tsum sib koom ua ke thiab txav mus tsis tu ncua - zam kev pib lossis nres. Muab cov hlau seem nyob rau hauv qhov chaw xaiv; indiscriminate dumping yog nruj me ntsis txwv tsis pub.
8. Khaws qhov nruab nrab- zaus tshuab hluav taws xob chav huv si; tsis txhob nqa cov nplaim taws, tawg, lossis lwm yam khoom siv sab hauv, thiab txwv tsis pub haus luam yeeb.
Raws li "Txoj Cai Rau Kev Txiav Txim Siab Muaj Kev Nyab Xeeb Loj hauv Kev Lag Luam thiab Kev Lag Luam," qhov muaj qhov tsis muaj - tsim khoom - cuam tshuam cov dej sawv ntsug ntawm hauv pem teb ntawm lub qhov hauv qab qhov nruab nrab - qhov cub zaus ua rau muaj kev phom sij loj. Tsis tas li ntawd, lub qhov cub lub qhov dej txias yuav tsum tau nruab nrog kev saib xyuas thiab lub tswb ntsuas rau qhov hluav taws xob qhov hluav taws xob thiab qhov hluav taws xob / qhov hluav taws xob ntws sib txawv, thiab cov cuab yeej no yuav tsum tau khaws cia hauv kev ua haujlwm kom raug. Cov neeg ua haujlwm tshwj xeeb yuav tsum tau txais kev cob qhia tshwj xeeb thiab tau txais daim ntawv pov thawj kev ua haujlwm uas yuav tsum tau ua ua ntej pib ua haujlwm. Qhov siab tsis tshaj 3,000 m; ambient kub ntawm 3℃thiab 40℃(tiv thaiv -khov ntsuas yuav tsum tau rau cov cheeb tsam hauv qab no 0 degree); txhua hli nruab nrab qhov siab tshaj plaws cov av noo tsis tshaj 90%; tsis muaj hmoov av conductive, explosive gases, los yog corrosive gases muaj peev xwm ua phem heev hlau los yog rwb thaiv tsev.
