Ukunyuka kwexabiso le-Pig Iron; Ukufika kwangethuba kwexesha lokuthunyelwa okuphezulu kwiShishini le-Cast Iron

Ixabiso lentsimbi yehagu linyukile kwakhona, kwaye ixesha eliphezulu lokuthunyelwa kwemveliso yentsimbi yentsimbi lifikile kwangethuba.

Kwiminyaka yakutshanje, imfuno yentsimbi yehagu inyukile. Ngenxa yenzuzo enkulu yeemveliso zentsimbi. I-China lilizwe elikhulu elivelisa izinto. Ukwanda ngokukhawuleza kwemfuno yentsimbi yehagu yentsimbi ephoswe kwishishini le-foundry kukhokelele ekunqongophaleni kwezixhobo zentsimbi ephoswe kunye ne-ductile kunye nokunyuka kwamaxabiso. Izixhobo zentsimbi zehlabathi zinqabile, kwaye ii-steel mills brawl steel Imfuno enamandla kunye nobonelelo olunganelanga. Ukunyuka kwamaxabiso ezinto ezikrwada kunye nokwanda kwempahla kuye kwabangela ukunyuka kwamaxabiso enkunkuma engeniswa kwamanye amazwe, ekugqibeleni okukhokelele ekufikeni kwangoko kwempahla ethunyelwa kakhulu kwishishini lentsimbi ephoswe.
