Sima whakaahuru me te moata
Whakaahuatanga
whakarōpūtanga
Ko te kumete whakaahuru, e mohiotia ana ko te kumete ahi, he mea hono ranei (te paura), ka whakamahia hei hono i nga hua whakangao i nga taonga pereki, kia rite ki nga mea ka taea te wehewehe ki te paru, te konumohe teitei, te silicon me te konupora moata whakaahuru, etc.
E kiia ana ko te kumete whakamaarama noa i hangaia mai i te paura clinker me te paru kirihou hei here me te kaihoko kirihou. Ko tona kaha i te pāmahana rūma he iti, me te hanganga o te hononga uku i te pāmahana teitei he kaha teitei.
Ki te hydraulicity, rangi whakapakeke ranei rauemi thermo-whakapakeke rite here, ka karanga matū herea kumete refractory, rite i raro i te hanganga o te pāmahana here uku i mua i te hanga o tetahi tauhohenga matū me te pakeke.
Ngā āhuatanga
Ko nga ahuatanga o te kumete whakaahuru: te kirihou pai, te hanga watea; te kaha here nui, te kaha o te waikura; refractoriness teitei, ki runga ki te 1650 ℃ ± 50 ℃; he pai te whakaekenga o te parae; te pai o te wera wera.
Taupānga
Ko te nuinga o nga mea e whakamahia ana i roto i te oumu coke, te oumu karaihe, te oumu pupuhi, te oumu pupuhi wera, te whakarewa, te ahumahi hangahanga, te miihini, te petrochemical, te karaihe, te kohua, te hiko hiko, te rino me te rino, te sima me etahi atu umanga ahumahi.
