Kev xaus ntawm qhov ua siab ntawm cov pa roj carbon ferrochrome hmoov yog 1550 ℃. Txhawm rau ua kom cov pob slag thiab cov hlau tawm hauv kev ua tiav, cov hlau yaj hauv kev tsim tshwj xeeb thiab kev tsim khoom yuav tsum tshaj qhov kub ntawm 100 ℃, yog li qhov xaus ntawm cov slag yuav tsum yog 1650 ℃. Yog tias cov slag dissolving taw tes qis me ntsis thiab qhov kub hauv qhov cub tawg qis, ces lub pob slag tuaj yeem tawm, tab sis hlau tsis yooj yim yuav raug rho tawm vim tias qhov me me hydrogen siab, thiab qhov xwm txheej ntawm tsawg hlau thiab ntau dua slag yog nyob. Thaum lub pob hluav taws xob tsuas pom, cov hlau tsis tuaj yeem tua, uas ua rau kev puas tsuaj loj heev.
Hauv kev lag luam hlau metallurgical, muaj cov pa roj carbon monoxide ferrochrome hmoov feem ntau yog siv hauv cov khoom siv carbon ferrochrome non-ferrous hlau thiab cov khoom siv hlau tsis tshua muaj roj carbon hlau ferrochrome hmoov. Cov pa roj carbon ferrochrome nonferrous hlau tau siv los ua cov khoom ntxiv rau kev tsim ntau yam tshwj xeeb nrog lub siab tawv, kev txhim kho corrosion, hnav tsis kam, kub tsis kam thiab huab cua oxidation tsis kam, xws li cov khoom cua kub tiv taus hlau, dov cov hlau tsis muaj hlau, cov khoom siv hlau, cov hlau tsis xeb , thiab lwm yam. Cov hlau cov khoom siv carbon ferrochrome feem ntau yog siv nrog cobalt, nickel, tungsten thiab lwm yam khoom smelting tshwj xeeb txhuas hlau.
Ferrochrome slag yog hom zoo limestone - zoo li cov khoom ua kom zoo nkauj hauv tsev. Nws cov ntau lawm thiab ua tiav nrog ntau yam qhob, nrog lwm cov xuab zeb thiab pob zeb cov khoom tsis muaj qhov zoo. Ferrochrome slag ntau lawm thiab ua khoom lag luam rau hauv cov xuab zeb gravel, nrog lub zog loj compressive thiab nto tshwj xeeb tshaj yog tsis du tus yam ntxwv. Ferrochrome slag xuab zeb gravel, nyob rau hauv hygroscopicity thiab porosity ntawm lub xeev ntawm nws lub zog compressive yuav tshaj limestone, thiab zoo ib yam li limestone.
