Cov lus qhia luv luv:
Tsis tshua muaj lub ntiaj teb ferroalloys yog ferroalloys ntawm lub ntiaj teb tsis tshua muaj cov ntsiab lus thiab hlau ua lub ntsiab lus.Rare lub ntiaj teb ferrosilicon yog lumpy, metallic luster, nyuaj thiab nkig, yooj yim mus zuaj. Lub ntiaj teb tsis tshua muaj ferrosilicon alloy yog nyiaj-grey. Lub ntiaj teb tsis tshua muaj ferrosilicon magnesium alloy ci xiav luster hauv cov nyiaj-grey matrix.
SIV:
* Cov ntaub ntawv tseem ceeb ntawm tus neeg sawv cev spheroidizing, vermicular tus neeg sawv cev thiab inoculant rau casting.
* Qhov tseem ceeb ntxiv thiab cov neeg sawv cev hauv cov hlau ntau lawm tuaj yeem ua lub luag haujlwm zoo hauv deoxidizing, desulfurizing thiab purifying steel.
* Cov kab mob sib xyaw ua haujlwm ntawm cov cam khwb cia hlau thiab cov hlau tshwj xeeb tuaj yeem txhim kho qhov fluidity ntawm molten steel thiab tshav kub tawg tsis kam ntawm cov casting, txo shrinkage, txo qhov sib cais (sib cais) thiab cais cov qauv cam khwb cia.
Ua kom zoo dua, deoxidizing, desulfurizing, tshem tawm impurities thiab huv hlau hauv kev tsim hlau.
