Hom cored hlau rau steelmaking

Hauv kev lag luam steelmaking, cored hlau plays lub luag haujlwm tseem ceeb, muab ntau yam khoom thiab cov alloys rau cov hlau los txhim kho nws qhov zoo thiab kev ua tau zoo.

Muaj ntau ntau hom cored hlau feem ntau siv nyob rau hauv cov txheej txheem steelmaking:

Calcium core hlau

Calcium cored hlau yog dav siv los ua deoxidizer thiab desulfurizer hauv kev ua haujlwm steel. Nyob rau hauv molten steel, nws tso tawm calcium, uas reacts nrog impurities xws li oxygen thiab sulfur los tsim cov non-metallic tebchaw uas yuav yooj yim tshem tawm. Cov txheej txheem no pab txhim kho kev huv thiab zoo tag nrho ntawm cov hlau, yog li txo qhov kev pheej hmoo ntawm qhov tsis xws luag thiab txhim kho nws cov khoom siv kho tshuab.

Hlau alloycore kab

Lwm hom kev siv cored hlau hauv steelmaking yog ferroalloy cored hlau. Cov hlau muaj ntau yam ferroalloys xws li ferrocalcium, ferrosilicon thiab ferromanganese. Cov hlau no tau nkag mus rau hauv cov hlau molten kom sib xyaw cov ntsiab lus xws li calcium, silicon thiab manganese. Cov ntsiab lus no pab txhim kho steel lub zog, corrosion kuj thiab lwm yam khoom zoo. Kev siv cov ferroalloy cored hlau ua kom yooj yim tswj cov ntsiab lus alloying thiab ua kom zoo ib yam thiab txhim khu kev qha steel muaj pes tsawg leeg.
