Nruam casting tshuab

Nruam casting tshuab ntau lawm txheej txheem.Lub siab kub molten hlau yog txuas ntxiv mus rau hauv ib los yog ib pab pawg ntawm cov dej-txias tooj liab crystallizers, thiab cov hlau molten yog maj mam solidified rau hauv lub plhaub dawb paug raws li periphery ntawm lub crystallizer.Tom qab cov hlau ua kua theem nce mus rau ib qho siab thiab lub plhaub dawb paug solidifies mus rau ib tug tej thickness, lub nro leveler rub tawm lub dawb paug, thiab lub slab yog txias los ntawm dej txau nyob rau hauv lub thib ob qhov chaw txias txias kom tag solidify lub slab, uas yog txiav. mus rau qhov ntev ruaj los ntawm cov cuab yeej txiav raws li qhov yuav tsum tau ua ntawm steel dov.Cov txheej txheem ntawm ncaj qha pouring high-temperature molten steel rau hauv billet yog hu ua nruam casting.Nws qhov tsos tau hloov pauv qhov txheej txheem ib-tawm dov ntawm steel ingots, uas tau dominated 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 cov khoom zoo, nws tau tsim sai heev.Nyob rau hauv niaj hnub kev lag luam steelmaking, txawm tias nws yog cov txheej txheem ntev steelmaking los yog cov txheej txheem luv luv steelmaking, kev faib cov caster txuas ntxiv yog yuav luag inevitable.
