Loaʻa i nā poloka heleuma nā pōhaku lepo i hoʻokuʻu ʻia a me nā tile perforaled me nā kaʻina hana o ʻelua ʻano o ka mīkini kaomi a me ka ninini ʻana. e like me nā koi hana o nā mea kūʻai aku, e koho i nā mea hana like me ka castable refractory o ka uhi ahi ma ke kī ʻana i ka wela kiʻekiʻe. heleuma poloka i kiʻekiʻe ikaika, maikaʻi erosion kū'ē waiwai a me ka maikaʻi spalling kū'ē, ka mea i ka basically ka hoʻonui like me ka umu ahi lining refractory castable.
Hana ʻia nā pōhaku heleuma i ke ʻano kiʻekiʻe o ka bauxite e like me nā mea maka i loaʻa i ka 48 ~ 80% alumina content a hoʻokumu ʻia ma ke kaomi ʻana a me ke kī ʻana i ka wela kiʻekiʻe. Hoʻohana nui ʻia nā poloka heleuma i nā kapuahi wela e like me ka umu hoʻomehana, ka ʻoihana kemika lanahu a me ka umu uila ma luna.

Hoʻohana nui ʻia nā poloka ahi heleuma no ka hale a me nā paia o ka umu wela me nā hiʻohiʻona o ka ikaika kiʻekiʻe, ka hana mechanical maikaʻi a me ka hana anti strip maikaʻi. a hiki ke hoʻohana ʻia i loko o nā kapuahi wela e like me ka umu wela, ka ʻoihana kemika lānahu kiln a me ka umu uila a me nā mea ʻē aʻe.
ʻO RS refractory factory kahi mea hoʻolako brick refractory heleuma i hoʻokumu ʻia i nā makahiki 90 o iwakālua mau kenekulia. ʻO ka hale hana refractory RS he loea i nā pōhaku ahi heleuma ma mua o 20 mau makahiki. inā loaʻa iā ʻoe kekahi koi o ka heleuma refractory block, a i ʻole he mau nīnau ma ka heleuma ahi e pili ana i nā hōʻailona kino a me nā kemika, e ʻoluʻolu e kelepona mai iā mākou no ka manuahi. a me ka hale hana refractory Rs ma ke ʻano he mea hana ʻoihana acid anchor refractory bricks ma Kina, he mau pono hoʻokūkū e like me kēia:
Kumukūʻai hoʻokūkū: E hoʻokūkū i nā huahana i kāu mākeke,
ʻIke nui: pale i nā māwae a me ka wili i nā pōhaku lepo,
Nā Moulds ʻokoʻa: E mālama i nā uku mold no ʻoe,
Ka Mana Mana Koʻikoʻi: E hoʻokō i nā koi o nā mea kūʻai aku,
Nā waihona nui: E hōʻoia i ka hoʻouna koke ʻana,
Hoʻopili ʻoihana: E pale i ka pōʻino a hoʻopaʻa i nā waiwai i ka lawe ʻana.
