Recarburizerfor steelmaking tare da recarburizer (ferrous metallurgy masana'antu misali na Jamhuriyar Jama'ar Sin, YB/T 192-2001 steelmaking tare da recarburizer) da kuma jefa baƙin ƙarfe da recarburizer, da wasu sauran kara kayan ma da amfani ga recarburizer, kamar birki kushin da Additives. kamar yadda gogayya kayan.Recarburizer nasa ne zuwa waje steelmaking, ironmaking recarburizer albarkatun kasa.High quality recarburizer ne makawa karin ƙari a samar da high quality karfe.

Amfani da carbon wakili:

A cikin smelting tsari, saboda rashin batching ko caji da wuce kima decarburization da sauran dalilai, wani lokacin sa a cikin karfe carbon abun ciki bai cika da bukatun na ganiya lokaci, sa'an nan zuwa ga ruwa karfe carburization.Commonly amfani carburizing wakili carburizing alade baƙin ƙarfe, electrode. foda, man fetur coke foda, gawayi foda da kuma coke powder.Converter smelting matsakaici da high carbon karfe, da yin amfani da man fetur coke dauke da 'yan impurities kamar yadda carburizing agent.The bukatun na recarburizer ga saman hura Converter steelmaking ne high gyarawa carbon, low abun ciki na ash , volatiles, sulfur, phosphorus, nitrogen da sauran ƙazanta, bushe, tsabta, da matsakaicin girman barbashi.

An kasu kashi kafaffen rukunin carbon zuwa:

2, a wajen tanderu carburizing:

(1) fesa graphite foda a cikin jaka

Yin amfani da graphite foda a matsayin recarburizer, da allura girma ne 40kg / t, da kuma carbon abun ciki na ruwa baƙin ƙarfe ana sa ran karuwa daga 2% zuwa 3% The zafin jiki na zub da baƙin ƙarfe kafin carburization ya 1600 ℃, da kuma matsakaita zafin jiki bayan carburization aka 1299 ℃.Jet graphite foda carburization, kullum yi amfani da nitrogen a matsayin m, amma a karkashin masana'antu samar yanayi, tare da matsa iska ne mafi dace, da kuma oxygen konewa a matsa iska don samar da CO, sinadaran dauki zafi iya rama wani ɓangare na yawan zafin jiki drop. da CO rage yanayi don inganta tasirin carburization.

(2) amfani da recarburizer lokacin da baƙin ƙarfe
