Ngokwezindlela ezahlukene zokuncibilikisa, uhlobo lwesithando kanye nosayizi wesithando sokuncibilikisa, kubalulekile futhi ukukhetha usayizi wezinhlayiya ze-carburizer ezifanele, ezingathuthukisa ngempumelelo izinga lokumuncwa kanye nezinga lokumuncwa kwe-iron liquid ku-carburizer, kugwenywe ukushiswa kwe-oxidation kanye nokulahleka kokushiswa kwe-carburizer okubangelwa usayizi wezinhlayiya ezincane kakhulu.
Usayizi wezinhlayiya zayo ungcono kakhulu: Isithando somlilo esingu-100kg singaphansi kuka-10mm, isithando somlilo esingu-500kg singaphansi kuka-15mm, isithando somlilo esingu-1.5 ton singaphansi kuka-20mm, isithando somlilo esingu-20 ton singaphansi kuka-30mm. Ukuncibilikisa i-Converter, insimbi yekhabhoni ephezulu, ukusetshenziswa kokungcola okuncane ku-ejenti yekhabhoni. Isidingo se-carburizer sokwenza insimbi ye-converter eqhutshwa phezulu (ejikelezayo) yikhabhoni ephezulu eqinile, okuqukethwe okuphansi komlotha, ukuguquguquka, i-sulfur, i-phosphorus, i-nitrogen nokunye ukungcola, kanye nosayizi wezinhlayiya owomile, ohlanzekile, omaphakathi. Ikhabhoni yayo eqinile C≥96%, ukuguquguquka ≤1.0%, S≤0.5%, umswakama ≤0.5%, usayizi wezinhlayiya ngaphakathi kuka-1-5mm. Uma usayizi wezinhlayiya ulungile kakhulu, uzosha kalula. Uma usayizi wezinhlayiya ukhulu kakhulu, uzontanta phezu kwensimbi encibilikisiwe futhi ungamuncwa kalula yinsimbi encibilikisiwe. Usayizi wezinhlayiya zesithando sokungenisa ungu-0.2-6mm, phakathi kwazo usayizi wezinhlayiya zensimbi nezinye izinsimbi zensimbi ungu-1.4-9.5mm, insimbi enekhabhoni ephezulu idinga i-nitrogen ephansi, kanti usayizi wezinhlayiya ungu-0.5-5mm, njll. Ukwahlulela nokukhethwa okuqondile kufanele kwenziwe ngokuya ngohlobo oluthile lwesithando sokushisa kanye neminye imininingwane.
