I-Ningxia yekhwalithi ephezulu ye-anthracite (umlotha ophansi oyingqayizivele, isibabule esiphansi, i-phosphorus ephansi, ikhabhoni engaguquki ephezulu, inani eliphakeme le-calorific) ibalwa ku-1200 ℃, inokumelana ne-oxidation eqinile, amandla aphezulu emishini, umsebenzi wamakhemikhali aphezulu, izinga eliphezulu lokuhlanza amalahle nezinye izici. Isetshenziswa kakhulu ukwandisa ikhabhoni ekwenzeni insimbi. Umsebenzi wayo ukuphakamisa izinga lokushisa ngokushesha, ngomphumela omuhle kanye nezinga elizinzile lokumuncwa kwekhabhoni. Ingasetshenziselwa ukulungisa okuqukethwe kwekhabhoni kanye ne-oxygen yensimbi encibilikisiwe, iguqule ukuqina nokuqina kwayo, futhi ngaleyo ndlela ithuthukise ikhono le-nucleation lensimbi encibilikisiwe kanye nekhwalithi yangaphakathi ye-billet.
