Ngaphansi kwethonya lentengo yomhlaba wonke ye-iron ore, intengo yensimbi yensimbi isanda kwenyuka futhi intengo yensimbi yengulube yaqala ukwenyuka. Futhi ukuvikelwa kwemvelo kuba nomthelela wokuthi i-ejenti yokungcwaba yekhwalithi ephezulu isiphelile. Bese kuthi intengo yensimbi ikhuphuke enyangeni ezayo. Nansi imininingwane elandelayo:
1 Insimbi yengulube ne-coke
E-Shandong, Shanxi, Jiangsu, Hebei, Henan nakwezinye izifunda nakuba ukuthunyelwa kwensimbi kukuncane, kodwa kukhona abakhiqizi abambalwa kakhulu ekukhiqizeni ngakho-ke ukusungula akukuningi. Ukukhuphuka kwezintengo zemakethe yensimbi, i-coke ne-ore amanani entengo akhuphukile, ngesonto eledlule insimbi yengulube ikhuphuke ngo-1% - 3%, i-coke ikhuphuke ngo-2% futhi kokubili i-inventory yehlisiwe. Inani eliphakeme lamandla ehlobo liyafika, isidingo kanye nentengo ye-coke izoqhubeka nokukhula. Kodwa ngenxa yokushisa okuphezulu kanye nenkathi yokuvala ifika, i-steel and foundries 'isidingo se-pig iron ayingcono, Kulindeleke ukuthi intengo inyuke hhayi kakhulu esikhathini esifushane.
2 I-ejenti ye-Scrap kanye ne-carburizing
I-cupola ye-Foundry yasuswa ngenxa yezindaba zemvelo, izinkampani eziningi zaqala ukushintsha inqubo yokuncibilika kwesithando somlilo kagesi, zisebenzisa izindleko eziphansi kanye nensimbi esetshenzisiwe kabusha kanye ne-agent carburizing ukukhiqiza i-ductile iron noma insimbi empunga. I-ejenti enhle yokungcwaba i-graphite iwukhiye, kodwa ingxenye yokuqala yonyaka ukuvikelwa kwemvelo kuholele ekuvalweni kwamafekthri amaningi kanye ne-ejenti yokungcwaba ingasekho esitokweni. Ngaphezu kwalokho, amanani entengo akhuphuka ngakho izindleko zezimboni zenyuka futhi nentengo yamapayipi ensimbi nezinto zokufakwayo ingase yenyuke.
