Corundum castable bụ ihe na-emegharị emegharị nke mejupụtara corundum (aluminom oxide, Al₂O₃) dị ka mkpokọta na matrix, jikọtara ya na ihe nrụnye dị elu na mgbakwunye. Ngwongwo ya pụrụ iche sitere na njirimara ebumpụta ụwa nke corundum, nke na-etu ọnụ ebe mgbaze karịrị 2000 Celsius, nkwụsi ike dị mma nke ọma, yana ike igwe dị elu. N'adịghị ka ihe refractory omenala, corundum castable na-enye ngwakọta pụrụ iche nke mgbanwe na ịdịte aka - ọdịdị ya na-enye ohere maka ntinye dị mfe n'ụdị na ihe owuwu dị mgbagwoju anya, ebe nnukwu ihe owuwu ya na-eguzogide spalling, abrasion, na chemical attack from slags, acids, and alkalis.
Otu n'ime uru bụ isi nke corundum castable bụ ntụgharị ya n'ofe ụlọ ọrụ. N'ime ụlọ ọrụ nchara, a na-eji ya eme ihe na ladles, tundishes, na ihe mgbawa ọkụ, ebe ọ na-anagide okpomọkụ igwe gbazere agbaze na mmeghachi omume slag na-eme ihe ike. Ndị na-emepụta ígwè na-adabere na corundum castable iji belata oge ọdịda nke ọdịda ihe onwunwe kpatara, n'ihi na ogologo ndụ ya na-arụ ọrụ na-atụgharị n'usoro nlekọta dị ole na ole yana ọnụ ala ọrụ. Maka ụlọ ọrụ simenti, a na-etinye corundum castable na mpaghara mgbanwe simenti na ọdụ ụgbọ elu dị elu, na-edi oke okpomọkụ na clinker ciment na-emebi emebi.

Na agafe nchara na simenti, corundum castable na-eme nke ọma na igwe anaghị agba nchara, imepụta iko, na ụlọ ihe mkpofu.

Akụkụ ọzọ na-adọrọ adọrọ nke corundum castable bụ arụmọrụ ya nwere ike ịhazi ya. Ndị na-emepụta ihe nwere ike ịhazigharị ihe mejupụtara corundum (dịka ọmụmaatụ, corundum ọcha, corundum aja aja, corundum tabular) na mgbakwunye iji kwado ihe ahụ na mkpa ngwa ngwa. Dị ka ọmụmaatụ, elu-alumina corundum castable (Al₂O₃ ọdịnaya ≥ 90%) na-enye nkwalite okpomọkụ maka gburugburu ultra-oke okpomọkụ, ebe obere ciment ma ọ bụ ultra-low-ciment formulations na-eme ka njupụta ma belata porosity, na-ebelata ntinye slag. Na mgbakwunye, nhọrọ castable corundum dị fechaa na-enye mkpuchi ọkụ na-emebighị ike igwe, dị mma maka atụmatụ ụlọ ọrụ na-azọpụta ike.
Mgbe ị na-ahọrọ corundum castable, ọ dị mkpa ka gị na onye na-ebubata ngwaahịa amara ama na-agbaso ụkpụrụ ịdịmma mba ụwa (dịka, ISO, ASTM). Corundum castable dị elu na-enweta njikwa mma siri ike, na-ahụ na arụmọrụ na-agbanwe agbanwe, ihe mejupụtara kemịkalụ kwụsiri ike, yana ihe nrụnye a pụrụ ịdabere na ya.
