5. Tom qab kev tsim kho ntawm prefabricated castables rau cov ntawv ua kom qeeb qeeb, cov qauv kev tsim kho yog qhov ceev, thiab lub sijhawm tsim kho yog luv.

6. Cov neeg siv tau tuaj yeem kho cov khoom ntawm cov khoom siv sib txawv thiab ntau yam ntau yam ntawm kev siv sib txawv ntawm kev siv thiab cov cai;

7. Cov khoom no yog cov khoom lag luam ib puag ncig zoo, uas tsis muaj tshuaj lom, tsis muaj kuab lom thiab dawb paug thaum siv.

Tom qab cov prefabricated feem ntawm cov qoob loo me me yog tsim, lawv cov txheej txheem tu, thaum cov khoom siv ntoo, nrog cov cim kev ua kom tig rov qab, nrog cov cim uas tig mus sab nraud; Thaum cov kev ua kom prefabricated yog hoisted rau hauv lub cub hluavtaws, cov khoob yuav tsum tau leveled thiab muaj av nkos refractory ntawm tib cov khoom. Yog tias qhov sib txawv yog loj heev, nws yuav tsum tau leveled nrog cov ntaub ntawv ntawm tib cov ntaub ntawv thiab rauj kom nws ntom.

Peb qhov prefabricated feem ntawm cov khoom siv roj castary yog siv nyob rau hauv ntau cov khoom siv carbon, thiab lwm yam. Peb nruj tswj cov khoom siv roj carbon, thiab lwm yam. Muab cov kev daws teeb meem chicks, Masas Kev Kho Mob, Masas Kho Kom Zoo thiab muaj kev daws teeb meem rau cov neeg siv khoom sib txawv.
