Ekhiqizeni indawo engamelana nokugqwala esifundeni sezindawo lapho kuthintwa khona igesi elishisayo le-boiler yokushisa yensimbi yensimbi, izingxenye ezihambisanayo zesikhunta sokuphonsa ziphathwa ngokuwasha okumnyama okuqukethe i-alloying element, okungcono 40- I-50% ferrosilicon, eguqula indawo enqenqemeni yensimbi engakaqiniswa engakabi yisikhumba sokumelana nokugqwala
Isidingo sokulawulwa kwezinto zokusetshenziswa sibaluleke kakhulu empumelelweni yokukhiqizwa kwensimbi kusuka ezinhlelweni zemifino nezindawo. Isihlabathi se-silica esisezingeni eliphansi sivame ukunganakwa ngokugxila okuyinhloko kuzengezo ze-bentonite. Izithasiselo ze-Carbonaceous zingathathwa ngokuthi "ububi obudingekayo" ukuqinisekisa ukuphela okuhle komhlaba nokuncipha kwamaphutha ahlobene nesihlabathi. Ezinye izithasiselo zisetshenziswa lapho amasistimu ephuma ebhalansi futhi wona wona engeza ngokuqhubekayo ebunzimeni bezinhlelo zegreenand. Ngokuphonsa okudinga ama-cores lokhu kuba yinkinga enkulu njengoba izinhlelo eziningi ze-resin zisetshenziselwa ukukhiqizwa okuyisisekelo futhi lokhu kufanele kucatshangelwe lapho kulawulwa womabili amazinga e-carbonaceous kanye nokubekwa kukonke kohlelo lwesihlabathi.
Imiphumela yamawele kukhabhoni eyengeziwe nokulahleka kokushiswa nokubekwa kwesihlabathi jikelele kudinga ukuqonda nokulawula ngokucophelela. Izindlela ezahlukahlukene zokulawula ziyahlolwa kufaka phakathi izindlela zendabuko ezifana nokushayisana nokulahleka kokushiswa kanye nezindlela zokunquma ze-bentonite nezindlela zokulinganisa. Izindlela ezintsha zokulawula ezifana nekhabhoni ephelele ziyabuyekezwa kanye nephakethe lilonke lezindlela zokuhlola nezokulawula.
Izindlela ezahlukahlukene zokubikezela zibhekwa njengesici sokulawula. Izinga lezithasiselo neqhaza lazo futhi okubaluleke kakhulu ukuthi ukuxhumana kwabo kugqanyisiwe, ngoba le yindawo evame ukunganakwa njengamadoda asungula impi alwela impumelelo ekulingweni kwekhwalithi okungaguquki. Izivivinyo zokulawula ezizayo eziphakanyisiwe zixoxwa ngokuhlanganiswa kokungeziwe kusihlanganisi.
Kubuye kubuyekezwe ukuhunyushwa kwemiphumela kanye nesenzo esidingekayo ukuze kuqinisekiswe ukulawulwa futhi okubaluleke kakhulu okungaguquguquki kwekhwalithi kusuka kuzinhlelo zemifino kanye nokugcizelela ekuqondeni nasekulawuleni okufakwayo kwe-carbonaceous ekusebenzeni kokulingiswa
