Kei te kiia hoki ko te castable aukati waikawa, ko tetahi o nga mea whakaahuru, a ka taea e ia te aukati i te horo o te waikawa, e whakamahia nuitia ana i roto i nga miihini kore-ferrous, ahumahi matū, tumere, me etahi atu. Ko te castable he nui ake te ihirangi o te kaihoko here me te makuku me te nui ake o te wai. Ko te refractory kore ahua he whanui te tono ka taea te whakamahi ma te ringihanga me te ramming ranei i runga i te kowhiringa o nga tikanga ratonga mo nga rawa me te kaihoko here.
He ngawari te mahi hangahanga castable waikawa kaore he taputapu motuhake. He kaha te kaha miihini me te kounga teitei o te castable waikawa. He ngawari te hanga ma te tikanga o te ringihanga. Ka taea te whakamahi tika i nga castables waikawa ki roto i te miihini me te kore pupuhi. Na ka taea e castable whakaahuru waikawa ātete te waikura reo waikawa o 800 ~ 1200 ℃ e taea te ringihanga huaina castable waikawa refractory ātete. Hangaia te castable ātete waikawa refractory ki te karaihe wai hei here, waikawa waikawa alkali ranei hei whakahiato me te paura, me te iti o te coagulant. Heoi ano, karekau he parenga ki te waikura na te kawakawa, te waikawa maaota, te waikawa pukoro me te ngako nui.
Ko te hanganga whānui o castable ātete waikawa ko: whakahiato refractory ātete waikawa (60-70%), paura (30-40%), me te konutai fluorosilicate (13% -16%) rite te māngai whakapakeke.

Ka whakamahia whānuitia te castable ātete waikawa i roto i te tipu petrochemical waikawa me te tipu waikawa pungatara.
Ka taea te maka ki roto i te riu o te tinana, ka taea hoki te hanga ki nga hua o mua. e whakamahia whanuitia ana mo nga whaanui o nga momo oumu me nga umu, a ka whakamahia nuitia te castable waikawa i roto i te oumu ahumahi o te ahumahi whakarewa, te ahumahi hinu, te ahumahi matū, te hanga whare me te ahumahi miihini mo te aukati i te wera teitei.
RS refractory wheketere he kaiwhakarato castable ātete waikawa ngaio i whakapumautia i te timatanga o te 90s o te rua tekau tau. Ko te wheketere refractory RS he mea motuhake i roto i nga riipene aukati waikawa mo te neke atu i te 20 tau. Mena kei a koe etahi tono mo te waikawa whakaahuru aatete, he patai ranei mo te whakamaarama aatete waikawa e pa ana ki nga tohu a-tinana me te matū, me waea mai ki a maatau mo te kore utu. me te Rs wheketere refractory hei kaiwhakanao castable atete waikawa ngaio i Haina, he painga whakataetae penei:
