I-cast slab eqhubekayo noma indawo ye-billet ibonisa imigodi engajwayelekile, ngokuvamile eyimigodi esemaceleni, kanye nemigodi eqondile.Ukucindezeleka nokunye okwengeziwe ku-austenitic stainless steel (uhlobo lwe-Cr18Ni9) kanye nensimbi enekhabhoni ephansi (carbon 0.10 kuya ku-0.15%) yendawo ye-slab.Ukucindezeleka kulula ukukhiqiza endaweni engemuva yobubanzi be-slab noma ingxenye ye-engeli ebanzi yanoma iyiphi ingxenye yobuso.Ukucindezeleka okukhulu kuqhekeka, kuqhekeke ingaphezulu lokungena okujulile kwensimbi ebonakale inezibazi, ngisho nokugqashuka kwesikhumba kabusha.Isizathu sokuthi ama-slab surface depressions akhiqizwa ahlukene.Njengoba izigaba zakuqala zokuqinisa igobolondo eliqinisiwe “elibanda kakhulu” ukufinyezwa kwezindlu ze-billet zendawo okubangelwa ukukhula okukhulu, okungalingani kuzoholela ekwakhekeni kokucindezeleka kwezindlu okubi;Igobolondo lensimbi ye-billet shrinkage longitudinal longitudinal kanye nengcindezi emile ebangelwa ukusebenzisana phakathi kokugoba kabusha lapho kusakazwa ukukhiqiza ukudangala kwezinhlangothi;Ushintsho lwe-ling luyenzeka (bheka ukuhluka kwesikwele nedayimane) kwe-billet eduze ne-engeli e-obtuse eduze nezindawo ze-longitudinal (ama-grooves) kanye neziphetho ezinde zemigodi yobubanzi be-slab isesikhunjini esibangelwa ukupholisa okungalingani;isizukulwane recessed futhi sikhathazeke ukwakheka kwensimbi, austenitic insimbi engagqwali kanye low carbon steel ekukhuleni igobolondo isikhunta ngokungalingani ukukhiqiza imigodi;ukusebenza okuphezulu kwensimbi engagqwali ukunwetshwa kokushisa kanye nokuqhutshwa kokushisa okuphansi okuthambekele ekucindezelekeni;UMnu. Ikhabhoni ephansi yaqina ngokushesha ngemva kokushintshwa kwe-austenite ibe ukufinyezwa kwevolumu ye-ferrite lapho insimbi enkulu lokhu kuthambekela kwesithako ukwenza imigodi ephezulu.Phakathi naleso sikhathi, isigameko sokucindezeleka siphinde sithinteke yizimo eziqhubekayo zokuphonsa: Ukusebenza njenge-powder yesikhunta engafanele, ukuguqulwa kwezinga lesikhunta sangaphakathi, izinguquko zejubane lokuphonsa nezinye izici.I-roller eqondile enamathelayo umzimba wangaphandle wensimbi, okhiqiza ukusatshalaliswa ngezikhathi ezithile kwemigodi (ama-indentation) kuzimbangela zendawo ye-slab.

Izixazululo yilezi: umkhuba wodonga lwesikhunta "ukupholisa kancane", ukunciphisa indawo engaphezulu eduze nokuqina kokushisa kwesikhunta, ukukhula okumile kanye negobolondo eliqinile, kungasetshenziswa isikhunta odongeni lokucwenga noma okuthiwa "isikhunta esiphezulu esishisayo" ukukhuthaza ukufana kwegobolondo elingenalutho;ukuguquguquka kwezinga lesikhunta kuncane (ngaphansi kuka-3mm), kusetshenziswa ukuguquguquka kokusebenza okuhle kakhulu, ukulungiswa kwe-flux viscosity ngokuhambisana nesivinini sokuphonsa, ukuqinisekisa ukugcwaliswa okufanayo;ungqimba lwe-slag lokuqina okufanele, ukulawulwa kwefilimu ye-slag ukuzinza ngokufanele ukushisa okuphezulu okuphezulu kanye nesivinini sokusakaza;ukusetshenziswa ezinengqondo umlomo wombhobho geometries kanye nokujula okunengqondo ukufakwa, gwema vortex liquid nabanye baye bavela esivuna igobolondo umfaniswano ukukhula, kanye unake ukuhlanza rollers ukuqondisa, kungaba zivimbele imigodi kwakheka.
