Raws li ntau txoj kev yaj, hom cub tawg thiab qhov loj ntawm lub cub tawg, nws tseem ceeb heev rau kev xaiv qhov loj me ntawm cov carburizer uas tsim nyog, uas tuaj yeem txhim kho qhov nqus thiab qhov nqus ntawm cov kua hlau rau carburizer, zam kev oxidation thiab hlawv poob ntawm carburizer los ntawm qhov me me ntawm cov khoom me me.
Nws qhov loj me me zoo tshaj plaws: 100kg cub tawg tsawg dua 10 hli, 500kg cub tawg tsawg dua 15 hli, 1.5 tuj cub tawg tsawg dua 20 hli, 20 tuj cub tawg tsawg dua 30 hli. Converter smelting, cov hlau carbon siab, kev siv cov khoom tsis huv hauv cov pa roj carbon tsawg dua. Qhov xav tau ntawm carburizer rau sab saum toj-blown (rotary) converter steelmaking yog cov pa roj carbon ruaj khov siab, cov ntsiab lus tsawg ntawm tshauv, volatilization, sulfur, phosphorus, nitrogen thiab lwm yam tsis huv, thiab qhuav, huv si, nruab nrab me me. Nws cov pa roj carbon ruaj khov C≥96%, volatiles ≤1.0%, S≤0.5%, noo noo ≤0.5%, me me me hauv 1-5 hli. Yog tias qhov loj me me zoo dhau, nws yuav hlawv yooj yim. Yog tias qhov loj me me tuab dhau, nws yuav ntab rau ntawm qhov chaw ntawm cov hlau molten thiab tsis yooj yim nqus los ntawm cov hlau molten. Qhov loj me ntawm lub cub tawg induction yog 0.2-6 hli, ntawm cov hlau thiab lwm yam hlau ferrous loj yog 1.4-9.5 hli, cov hlau carbon siab xav tau nitrogen tsawg, thiab qhov loj me yog 0.5-5 hli, thiab lwm yam. Kev txiav txim siab tshwj xeeb thiab kev xaiv yuav tsum tau ua raws li hom cub tawg hom smelting workpiece thiab lwm yam ntsiab lus.
