Eshaya insimbiIngabe insimbi eye yakhiwe ngokuphelele ngokungezwa kwe-ejenti ngaphambi kokuphonsa okunjalo ngaphandle kokuvela kwegesi ngesikhathi sokuqina. Kuboniswa ngezinga eliphakeme le-homogeneity yamakhemikhali nenkululeko emaphandleni egesi.

Insimbi ebulewe ye-Semi-abulale kakhulu i-dooxidaged Steel, kepha i-carbon monoxide ishiya i-blowhole hlobo porosioli esatshalaliswa kulo lonke i-INGOT. I-porotiolity isusa ipayipi elitholakala ensimbi elibulawe futhi landisa isivuno cishe ku-90% ngesisindo. Insimbi ebulewe yesikhathi isetshenziselwa insimbi ehlelekile ngokuqukethwe kwekhabhoni phakathi kuka-0,15 no-0.25% carbon, ngoba igingqe, okuvinjelwe impasi.

Insimbi yensimbi, eyaziwa nangokuthi ukudweba ikhwalithi esezingeni eliphezulu, akunankinga yokungabi nabenza i-ejenti ye-decoxidizing engezwe kuyo ngesikhathi sokuphonsa okubangela i-carbon monoxide ivele ngokushesha kusuka ku-Ingot. Lokhu kubangela izimbobo ezincane zokushaya ebusweni obuvaliwe kamuva kwinqubo eshisayo yokugoqa. Insimbi ebaluleke kakhulu inokuqukethwe kwekhabhoni ngaphansi kuka-0.25%, okuqukethwe kwe-manganese ngezansi kwe-0.6%, futhi akukuhlanganisiwe nge-aluminium, i-silico, ne-titanium.ue kuya kokungafani kwezici ezishisayo.
