Yuav Ua Li Cas Melt Kub Rolled Coils?

Kub dov kauj yog ib hom ntawv hlau cov khoom tsim los ntawm cov txheej txheem kub dov, feem ntau siv hauv kev tsim cov tsev, cov khoom siv tsheb, cov kav dej, thiab cov ntim khoom. Nyob rau hauv cov txheej txheem ntawm cov kub-dov coils, melting yog ib qho tseem ceeb kauj ruam. Hauv qab no, peb yuav muab cov ncauj lus qhia ntxaws ntxaws txog cov txheej txheem melting ntawm kub dov coils.
Cov txheej txheem melting ntawm kub dov coils feem ntau suav nrog peb theem tseem ceeb: kev npaj cov khoom siv raw, kev ua haujlwm ntawm lub cub tawg, thiab casting thiab sib sau.
Thawj theem yog kev npaj cov khoom siv raw. Cov ntaub ntawv tseem ceeb rau kub dov coils yog hlau ore, xws li hlau ore, chromium ore, npib tsib xee ore, thiab lwm yam. Thaum lub sij hawm tsim cov txheej txheem, nws yog ib qho tsim nyog yuav tau ntxiv qee cov ntsiab lus alloying los txhim kho cov khoom siv kho tshuab thiab corrosion kuj ntawm daim ntawv. hlau. Yog li ntawd, cov txheej txheem npaj cov khoom siv raw yuav suav nrog kev sib xyaw thiab sib faib ntau yam ores thiab alloying cov ntsiab lus kom ntseeg tau tias cov ntawv melted muaj cov tshuaj lom neeg uas xav tau.
Cov theem tom ntej yog kev ua haujlwm ntawm qhov cub smelting. Kub dov coils feem ntau melted siv blast furnaces los yog hluav taws xob arc rauv. Blast furnace yog ib qho khoom siv rau smelting molten hlau, uas tuaj yeem kho cov khoom siv raw xws li ore thiab coke rau hauv cov hlau molten nyob rau hauv qhov kub thiab txias. Lub tshuab hluav taws xob arc rauv siv hluav taws xob arc cua sov kom yaj cov khoom siv hlau ua kua hlau. Thaum lub sijhawm ua haujlwm ntawm lub qhov cub smelting, cov neeg ua haujlwm yuav tsum tswj xyuas qhov ntsuas kub, siab, thiab redox ib puag ncig hauv lub cub tawg raws li kev xav tau los xyuas kom meej tias cov ore thiab alloy cov ntsiab lus tuaj yeem ua tiav thiab sib xyaw ua ke.
Thaum kawg, muaj qhov casting thiab tsim theem. Lub melted kua hlau yuav muab poured rau hauv ib tug casting pwm, txias thiab solidified los ua ib tug cam khwb cia billet. Cov cam khwb cia hlau yog hloov mus rau hauv cov khoom kub dov coil uas ua tau raws li cov lus qhia los ntawm ntau yam txheej txheem xws li dov thiab ncab.
Zuag qhia tag nrho, cov txheej txheem melting ntawm kub dov coils yog ib tug complex lub cev thiab tshuaj txheej txheem uas yuav tsum tau nruj tswj ntawm raw cov ntaub ntawv muaj pes tsawg leeg, melting txheej txheem tsis, thiab tsim cov txheej txheem los xyuas kom meej cov khoom ntawm ruaj khov zoo coil khoom. Hauv kev tsim khoom tiag tiag, los ntawm kev tshawb fawb thiab tsim nyog cov txheej txheem melting thiab cov cuab yeej siv thev naus laus zis, kev tsim khoom zoo thiab cov khoom zoo ntawm cov kub dov coils tuaj yeem txhim kho kom tau raws li kev xav tau ntawm kev lag luam.
