Dab tsi yog Hom Slag?

Slag yog cov khoom lag luam hauv cov txheej txheem hlau ntawm lub tshuab hluav taws xob tawg. Nyob rau hauv cov txheej txheem ntawm kev tsim hlau, hlau oxide raug txo kom muaj hlau hlau ntawm qhov kub thiab txias. Cov impurities xws li silica thiab alumina nyob rau hauv cov hlau ore hnov ​​​​mob nrog txiv qaub los ua cov khoom molten feem ntau yog tsim los ntawm silicates thiab silicoaluminates. Tom qab quenching thiab txias, nws dhau los ua cov khoom siv xoob thiab ntxeem tau, uas yog hu ua blast furnace slag, abbreviated li slag.

Muaj ntau hom slag, xws li cam khwb cia hlau slag (slag tawm thaum lub sij hawm smelting ntawm cam khwb cia hlau), steelmaking npua hlau slag (slag tawm thaum lub sij hawm smelting ntawm npua hlau rau steelmaking), thiab tshwj xeeb npua hlau slag (slag tawm thaum lub sij hawm lub smelting npua hlau). smelting npua hlau nrog hlau ore uas muaj lwm yam hlau, xws li manganese slag thiab magnesium slag).
