Mpweya wachitsulo wa carbonzolakwika zamkati zimapangidwira mu carbon steel smelting defect smelting and casting process, monga tsankho, zopanda zitsulo inclusions, porosity, shrinkage ndi ming'alu.

Kusiyanitsa

Kusiyanitsa ndiko kugawidwa kosagwirizana kwa mankhwala muzitsulo, makamaka zinthu zovulaza monga sulfure, kupindula kwa phosphorous mu ingot.

Zosagwirizana ndi zitsulo

Zosakaniza zopanda zitsulo zimatanthawuza zosakanikirana zopanda zitsulo muzitsulo zomwe zili ndi zonyansa monga sulfides ndi oxides.

Stomata

Stomata amatanthauza chitsulo ndi mpweya monoxide mpweya zotsatira kwaiye mu kuthira sangathe mokwanira kuthawa ndi kukhala ting'onoting'ono pores mu ingot.

Kuchepa

Shrinkage ndi chifukwa cha madzi zitsulo ingot nkhungu kuchokera kunja kupita mkati, buku contraction pa solidification pansi-mmwamba, chifukwa mlingo akutsikira, chomaliza solidification wa mbali madzi zitsulo sangathe kuwonjezeredwa mawonekedwe.

Mng'alu

Kukhazikika kwazitsulo zamadzimadzi mu dongosolo chifukwa cha zifukwa zosiyanasiyana kupsinjika, ming'alu yamanjenje imatha kuwoneka yokulirapo.
