Ipayipi lensimbi ye-carbonamaphutha angaphakathi akhiqizwa ku-carbon steel smelting defect defect defect and casting process, njengokuhlukanisa, ukufakwa okungeyona insimbi, i-porosity, i-shrinkage kanye nokuqhekeka.

Ukuhlukaniswa

Ukuhlukaniswa ukusatshalaliswa okungalingani kokwakheka kwamakhemikhali ensimbi, ikakhulukazi izakhi eziyingozi ezifana nesibabule, ukunothisa kwe-phosphorus ku-ingot.

Ukufakwa okungezona ezensimbi

Ukufakwa okungezona ezensimbi kubhekisela ekufakweni okungeyona insimbi ensimbi equkethe ukungcola okufana nama-sulfide nama-oxides.

Stomata

I-Stomata ibhekisela kumphumela wegesi yensimbi ne-carbon monoxide okhiqizwa ekuthululeni awukwazi ukuphunyuka ngokugcwele futhi uhlale ezimbotsheni ezincane ku-ingot.

Ukuncipha

I-shrinkage ibangelwa isikhunta se-ingot yensimbi ye-liquid kusuka ngaphandle kuya ngaphakathi, ukufinyela kwevolumu ngesikhathi sokuqinisa phansi-up, ngoba izinga lehla, ukuqina kokugcina kwezingxenye zensimbi eziwuketshezi azikwazi ukungezwa kwifomu.

Ukuqhekeka

Ukuqiniswa kwensimbi ewuketshezi ngokulandelana ngenxa yezimbangela ezihlukene zokucindezeleka, imifantu yokungezwani ingase ibonakale izingxenye ezinkulu.
