Taw qhia ntawm qhib kev noj qab haus huv steel
Qhib hearth steel yog hais txog carbon hlau thiab zoo tib yam qis-alloy steel uas smelted los ntawm qhib hearth. Raws li cov khoom ntiag tug ntawm cov khoom siv hauv ob sab phlu, nws muab faib ua cov kua qaub hearth steel thiab alkaline hearth steel. Cov txheej txheem los kho tus hlau molten nrog argon nyob rau hauv qhov qhib-hearth molten pas. Kev sim tau nqa tawm hauv qhib qhov cub ntawm qhov rooj nrog cov muaj peev xwm ntawm 150, 300 thiab 430t. Cov hlau smelted siv cov khoom siv txhuam seem-pov tseg raws li cov txheej txheem tam sim no. Lub tshuab cua hlau Ar tau ua tiav los ntawm rab phom pa oxygen ntawm lub cub tawg sab saum toj, thiab kev siv roj kis yog 400 txog 1200 m / (h · rab phom). YKOC-1 sensor tau siv los xyuas cov pa oxygen hauv lub melt ua ntej thiab tom qab txau. Hauv pawg smelting, cov qauv hlau thiab slag raug xaiv los ntawm lub tshuab ua kom sov.
