Smelting furnaces yog cov cuab yeej ua haujlwm tseem ceeb hauv kev tsim khoom, dav siv hauv cov hlau, tsis yog{0}}ferrous hlau, cov khoom siv hauv tsev, tshuaj, vuam, thiab lwm yam. Hauv kev lag luam steel, smelting furnaces yog siv dav hauv kev tsim hlau, steelmaking, thiab forging txheej txheem; nyob rau hauv lub tsev cov ntaub ntawv kev lag luam, lawv yog dav siv los yaj ntau yam khoom siv tsev; thiab hauv kev lag luam chemical, lawv tau siv dav los tsim ntau yam tshuaj raw khoom thiab cov khoom lag luam.
Lub qhov cub smelting yog ib qho khoom siv uas ua kom sov cov khoom hlau lossis lwm yam khoom siv rau lub xeev molten rau smelting, refining, thiab alloying txheej txheem. Smelting furnaces yog dav siv nyob rau hauv cov hlau, uas tsis yog -ferrous hlau, tsev cov ntaub ntawv, thiab tshuaj industries, ua si ib tug tseem ceeb luag hauj lwm nyob rau hauv zus tau tej cov castings thiab tsim tshwj xeeb steels thiab alloy cov ntaub ntawv.
