Yakaderera sarufa yezvinhu musimbi yakanyungudutswa yakanyungudutswa neyakanyungudutswa muvira

Pakunyungudutsa simbi yakakandwa ne kudonhedzwa kunyorera vira, nekuda kwehuwandu hwezvimedu muchoto chemoto uye ingots shoma yesimbi yenguruve, iyo sulfur yemukati mune zvigadzirwa yakadzikira, uye hapana kusangana necoke panguva yekunyungudutswa, uye hapana nzira yekutora sarufa kubva. iyo coke. Musimbi yakanyungudutswa inowanikwa nekuwedzera sarufa uye kunyungudutswa, sulfur yemukati kazhinji iri pasi pe0.06%. Kune yakaderera-sarufa yakanyungudutswa iron, ichokwadi chinozivikanwa kuti mhedzisiro yeinoculation kurapwa haina kunaka.

Naizvozvo, kana kunyungudutswa muchoto chekunyungudika, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune iyo sarufa yemukati musimbi yakakandwa, uye inofanirwa kuchengetedzwa pamusoro pe0.06%. Kana pasina chikamu chesarufa muzvigadzirwa, kazhinji huwandu hwakakodzera hweferrous sulfide hunogona kuwedzerwa kuwedzera sarufa.
