Dab tsi yog Hom Hlau Phaj Cov Khoom Siv

Cov phaj hlau yog cov hlau ua los ntawm cov hlau molten, thiab feem ntau yog siv hauv cov tsev lag luam. Ntau hom steel phaj siv sib txawv, thiab cov tswv yuav tsum yuav raws li lawv tus kheej xav tau thaum yuav. Piv txwv li, cov khoom siv hlau uas yuav tsum tau raug huab cua rau lub sijhawm ntev yuav tsum muaj huab cua zoo. Yog li, dab tsi yog hom steel phaj cov ntaub ntawv? Lawv qhov zoo thiab qhov tsis zoo yog dab tsi? Cia peb saib luv luv ntawm nws nrog tus editor.

Cov ntaub ntawv steel phaj yog dab tsi?

1. Ordinary nruab nrab thiab tuab steel daim hlau

Ordinary nruab nrab thiab tuab steel phaj yog ib hom deoxidized steel, cov ntsiab lus oxygen ntawm cov hlau molten yog qhov siab, thiab cov roj ntau yuav raug tsim nyob rau hauv cov txheej txheem ntau lawm kom boil cov hlau molten, yog li nws tseem hu ua boiling steel. .

Qhov zoo: Qhov saum npoo ntawm cov phaj hlau no yog tus du, qhov zoo yog qhov zoo heev, thiab nws yooj yim rau kev ua. Vim tias cov phaj hlau no tsis muaj qhov sib xyaw ua ke, cov pa oxygen absorber tsawg heev, thiab tus nqi yuav qis dua li ntawm lwm cov hlau phaj.

Qhov tsis zoo: Cov hlau no muaj cov ntsiab lus roj ntau hauv, ntau impurities, tsis yooj yim rau vuam, thiab cov kabmob muaj peev xwm loj dua li lwm cov hlau phaj, yog li nws tsis tsim nyog rau kev siv los ua cov khoom siv uas yuav tsum tau tiv taus lub ntiajteb txawj nqus.

2. Ordinary carbon steel sedative steel phaj

Thaum lub molten hlau yog poured rau hauv lub steel ingot, nws cov tshuaj tiv thaiv yog tus nyob ntsiag to thiab yuav tsis muaj boiling xeev.

Qhov zoo: Tsis muaj roj hauv cov phaj hlau no, muaj cov impurities tsawg dua, lub zog tsis sib xws, thiab nws muaj kev ua haujlwm vuam zoo. Nws yog dav siv rau cov khoom xav tau

Qhov tsis zoo: Qhov zoo ntawm qhov chaw ntawm lub phaj steel no tsis zoo li cov phaj boiling, muaj cov concentrated shrinkage qhov, thiab tus nqi kuj tseem kim.
