Phantsi kweempembelelo zexabiso lamazwe ngamazwe lentsimbi ekrwada, kutsha nje ixabiso lentsimbi yentsimbi liye lanyuka kwaye ixabiso lentsimbi yehagu liqalise ukunyuka. Kwakhona ukhuseleko lokusingqongileyo luchaphazela ukuba umgangatho ophezulu we-carburizing agent iphelile. Ke ixabiso lokuphosa intsimbi linokunyuka kwinyanga ezayo. Nazi iinkcukacha zilandelayo:
1 Intsimbi yehagu kunye necoke
E-Shandong, e-Shanxi, e-Jiangsu, e-Hebei, e-Henan nakweminye imimandla nangona ukuthunyelwa kwentsimbi kukuncinci, kodwa bambalwa kakhulu abavelisi kwimveliso ngoko ke uluhlu lwempahla aluninzi. Ukunyuka kweemarike zensimbi, i-coke kunye namaxabiso e-ore aneempembelelo zokuba amaxabiso e-iron anyukile, kwiveki ephelileyo i-iron yehagu inyuke nge-1% - 3%, i-coke yenyuka nge-2% kwaye zombini i-inventory iyancipha. Incopho yamandla ehlobo iza, imfuno kunye nexabiso lecoke liya kuqhubeka nokukhula. Kodwa ngenxa yokushisa okuphezulu kunye nexesha elivaliweyo liza, i-steel kunye ne-Foundries 'imfuno ye-pig iron ayingcono, Kulindeleke ukuba ixabiso linyuke lingekho kakhulu kwixesha elifutshane.
2 Isilahlwa kunye nearhente yokungcwaba
I-cupola ye-Foundry yasuswa ngenxa yemicimbi yokusingqongileyo, iinkampani ezininzi zaqala ukutshintsha inkqubo yokunyibilika kwesithando sombane, usebenzisa ixabiso eliphantsi kunye nentsimbi esetyenzisiweyo esetyenzisiweyo kunye ne-carburizing agent ukuvelisa i-ductile iron okanye intsimbi engwevu. Isitshixo se-graphite carburizing agent yeyona nto iphambili, kodwa kwisiqingatha sokuqala sonyaka ukhuseleko lokusingqongileyo lukhokelele ekubeni iifektri ezininzi zivale kwaye i-carburizing iphele. Ngaphezu koko, amaxabiso ezinto ezilahliweyo anyukile ngoko amaxabiso emizi-mveliso anyukile kwaye nexabiso lemibhobho yokugalela yentsimbi kunye nezifakelo linokunyuka nalo.
