Tsib qhov zoo ntawm kev siv cov ntaub ntawv ramming qhuav:

1. Cov txheej txheem sib xyaw thiab sib xyaw tuaj yeem txo qis, thiab cov cua sov tuaj yeem tsim ncaj qha yam tsis muaj cov tshuaj ntxiv thiab dej.

2. Txhim kho kev siv qhov kub thiab txias hlau. Vim yog qhov ua tau zoo ntawm cov hmoov tshwj xeeb sib xyaw ua ke, qhov refractoriness thiab load softening kub tau zoo dua, kev ntsuas kub tuaj yeem nce ntxiv 50-100 ℃, thiab nws tub nkeeg. Hauv qab 1700 ℃, nws tsis cuam tshuam nrog cov hlau yaj, thiab poob ntawm cov hlau hlau me me. Qhov zoo ntawm cov hlau yaj yog ruaj khov.

3. Zoo slag kuj thiab corrosion kuj. Acidic thiab alkaline molten slag tsis hnov ​​mob nrog lub qhov cub tawg, nws cov slag tsis kam yog qhov zoo, kev tiv thaiv xeb yog qhov zoo dua, thiab kev yaig tsuas yog 1/3 ntawm cov nqi hluav taws xob quartz.

4. Nws yog kev coj ua kom muaj cov nplai dav thiab cov tub ntxhais tsis muaj qhov cub tawg ntawm ntau lub peev xwm. Muaj ntau hom smelting, thiab nws tau siv los zom txhua hom npua hlau, carbon hlau, tshwj xeeb yog cov hlau cam khwb cia grey, zas hlau thiab lwm yam hlau tsis huv.

5. Kev siv siab ua haujlwm tau zoo, txuas ntxiv ua haujlwm rau lub neej, lub hnub ci rauv yog 2-3 npaug ntawm qhov zoo ib yam li hauv ob sab phlu. Nws tuaj yeem txo tus naj npawb ntawm kev tsim, txo cov neeg ua haujlwm, cov khoom siv, cov khoom siv, lub zog, kev siv peev thiab kev tsim khoom ncaj qha, thiab muaj txiaj ntsig zoo dua hauv zej zog thiab nyiaj txiag.
