Dab tsi yog Lub Tshuab Nruam Casting

Nruam casting tshuab ntau lawm txheej txheem. High-temperature molten steel yog txuas ntxiv mus rau hauv ib los yog ib pawg ntawm cov dej-txias tooj liab crystallizers. Cov hlau molten maj mam solidifies rau hauv ib lub plhaub raws qhov periphery ntawm crystallizer. Thaum cov kua steel theem nce mus rau ib qho siab, lub plhaub solidifies mus rau ib tug tej thickness thiab ces lub nro leveling tshuab yuav lub billet yog rub tawm thiab txias los ntawm cov dej txau nyob rau hauv lub thib ob cua txias cheeb tsam kom tiav solidify lub billet, thiab txiav mus rau hauv lub txias. ib qho ntev ntev los ntawm cov cuab yeej txiav raws li cov kev xav tau ntawm steel dov. Cov txheej txheem no ntawm cov dej kub kub molten steel ncaj qha mus rau hauv steel billets yog hu ua nruam casting. Nws qhov tshwm sim tau hloov pauv cov txheej txheem steel ingot dov uas tau ua tiav rau ib puas xyoo. Vim tias nws yooj yim rau cov txheej txheem ntau lawm, txhim kho kev tsim khoom thiab cov khoom siv hlau, txuag hluav taws xob, txo cov nqi tsim khoom, thiab muaj qhov zoo ntawm cov khoom zoo, nws tau tsim sai heev. Rau niaj hnub no cov tuam txhab steelmaking, txawm hais tias lawv yog cov txheej txheem ntev steelmaking los yog cov txheej txheem luv luv steelmaking, nws yuav luag inevitable rau nruab nruam casting tshuab.
