Iziphene zemveli inkqubo rolling steel

The inkqubo yentsimbi rolling yemveli kukuba iibhilidi zentsimbi zixutywe kwaye zipholile, zihanjiswe kwi-rolling mill, kwaye emva koko zifudunyezwe kwisithando somlilo sokufudumala kwintsimbi. Le nkqubo ineziphene ezimbini:

1. Emva kokuba i-billet itsalwe kwi-caster eqhubekayo yokwenza insimbi, izinga lokushisa kwibhedi yokupholisa liyi-700-900 ° C, kwaye ukushisa okufihliweyo kwe-billet akusetyenziswanga ngokufanelekileyo.

2. Emva kokuba i-billet eqhubekayo yokuphosa iqhunyiswa sisithando sokufudumala, ubuso be-billet buya kulahlekelwa malunga ne-1.5% ngenxa ye-oxidation.

Uhlalutyo lwenzuzo yokonga amandla:

1. Ukusetyenziswa kwamalahle kwi-original yokufudumeza i-billet yokufudumeza inkqubo yi-80 kg / toni yensimbi (ixabiso le-calorific 6400 kcal / kg), elilingana ne-72 kg yamalahle aqhelekileyo; emva kokuguqulwa kweteknoloji, inkqubo yokusetyenziswa kwamandla yi-38 kWh ngetoni nganye yentsimbi, elingana ne-13.3 kg yamalahle asemgangathweni.

2. Ngokusekelwe kwimveliso eqikelelweyo yonyaka yeemveliso zetsimbi zeetoni ezingama-600,000, ukugcinwa kwonyaka kwamalahle aqhelekileyo: (72-13.3) ÷ 1000 × 600,000 iitoni = 35,220 iitoni zamalahle aqhelekileyo.

3. Umgaqo wokonga amandla:

Emva kokuba i-billet itsalwe kumatshini oqhubekayo wokuphosa, ubuso bunobushushu be-750-850, kwaye ubushushu bangaphakathi bude bufikelele kwi-950-1000 ° C. Enye yemigaqo esisiseko yokufudumala kwe-induction yimpembelelo yesikhumba, leyo kukuba amandla obushushu ahanjiswa ngokuthe ngcembe ngaphakathi ukusuka kwindawo yokufudumala. Ngaphezulu, isinye kwisithathu se-billet yangaphakathi ayifuni ukufudumeza. Ngokwemilinganiselo eyahlukeneyo ye-billet ye-cross-sectional, khetha iifrikhwensi ezahlukeneyo ukufumana ukusebenza kakuhle kokufudumeza.

4. Amanqaku okonga amandla:

a) Izinga eliphezulu lokusetyenziswa kwamandla okufudumala kwe-induction lingaphakama ukuya kuma-65 ukuya kwi-75%, ngelixa i-furnace yendabuko yokuvuselela i-25 kuphela kwi-30%.

b) I-oxidation yendawo ye-billet yokufudumala i-induction i-0.5% kuphela, ngelixa i-furnace yokuvuselela inokufikelela kwi-1.5-2%.
