Raws li kev sib txawv ntawm cov txheej txheem melting, hom rauv thiab qhov cub melting qhov loj, nws tseem ceeb heev uas yuav tau xaiv qhov tsim nyog carburizer particle loj, uas tuaj yeem txhim kho qhov nqus thiab nqus tus nqi ntawm cov kua hlau rau carburizer, tsis txhob oxidation thiab hlawv ntawm carburizer tshwm sim. los ntawm me me particle loj.
Nws qhov loj me yog qhov zoo tshaj plaws: 100kg rauv yog tsawg dua 10mm, 500kg rauv yog tsawg dua 15mm, 1.5 tuj rauv yog tsawg dua 20mm, 20 tuj rauv tsawg dua 30mm.Hloov smelting, siab carbon steel, siv tsawg impurities nyob rau hauv tus neeg sawv cev carbon.Qhov yuav tsum tau muaj ntawm carburizer rau sab saum toj-blown (rotary) converter steelmaking yog siab ruaj carbon, tsis tshua muaj cov ntsiab lus ntawm tshauv, volatilization, sulfur, phosphorus, nitrogen thiab lwm yam impurities, thiab qhuav, huv si, nruab nrab particle loj.Nws tsau carbon C≥96%. , volatiles ≤1.0%, S≤0.5%, noo noo ≤0.5%, particle loj nyob rau hauv 1-5mm.Yog tias qhov loj me me dhau lawm, nws yuav hlawv yooj yim.Yog hais tias lub particle loj yog tuab heev, nws yuav ntab rau saum npoo ntawm molten steel thiab tsis yooj yim absorbed los ntawm molten steel.Qhov loj me me ntawm induction rauv yog 0.2-6mm, ntawm qhov loj me ntawm cov hlau thiab lwm yam hlau ferrous yog 1.4-9.5mm, siab carbon steel yuav tsum tsis tshua muaj nitrogen, thiab particle loj yog 0.5-5mm, thiab lwm yam kev txiav txim siab thiab xaiv yuav tsum tau ua raws li qhov tshwj xeeb ntawm qhov cub hom smelting workpiece thiab lwm yam ntsiab lus.
