Kiʻekiʻe alumina refractory castable

High-alumina castable mea refractory castable i kiʻekiʻe-alumina maka mea e like me ka aggregate a me ka pauka a me ka binder.

E hoʻouna i ka leka uila iā mākou +86 (0) 371-88551993

Nā kikoʻī

Hoʻohana nui ʻia ka alumina refractory castable i ka masonry a me ka mālama ʻana i nā kiln ʻoihana. ʻO nā mea hoʻoheheʻe alumina kiʻekiʻe maʻamau, ʻo ia ka portland cement castable, calcium aluminate cement castable, wai aniani hoʻopaʻa ʻia castable, phosphate hoʻopaʻa castable a pēlā aku. Me ka hoʻomau mau ʻana o nā ʻano huahana, ua hoʻomaikaʻi maikaʻi ʻia ka maikaʻi o nā mea hoʻoheheʻe alumina kiʻekiʻe, e komo pū me nā mea hoʻoheheʻe haʻahaʻa haʻahaʻa, nā mea hoʻoheheʻe haʻahaʻa haʻahaʻa a me nā pahu kima ʻole.

Hana Huahana

ʻO ka umu ahi Ferrosilicon kahi umu uila ʻoihana e hoʻopau i ka mana nui a he ʻano o ka umu ahi i hoʻopaʻa ʻia. ʻO ka ferrosilicon furnace e pili ana i ka pūpū kapuahi, ka uhi o ka umu ahi, ka uhi o ka umu, ka ʻupena pōkole, ka ʻōnaehana hoʻoluʻu wai, ka ʻōnaehana o ka uahi, ka ʻōnaehana hoʻoneʻe lepo, ka pūpū electrode, ka hoʻokuʻu ʻana i ke kaomi electrode a me ka ʻōnaehana hāpai, ka hoʻouka ʻana a me ka wehe ʻana o ka ʻōnaehana, ka mea hoʻoponopono, nā mea puhi ahi, hydraulic. ʻōnaehana, transformer A me nā mea uila like ʻole, a me nā mea ʻē aʻe, koi nui ka hoʻohana ʻana i nā mea refractory.

I ka makahiki 2006, ua hoʻokumu ʻia kā mākou hale hana ma Yuzhou, ke kumu kumu kumu. ʻO ka bauxite alumina kiʻekiʻe i loko o ka ʻoihana refractory e pili ana i ka ʻaila bauxite me kahi maʻiʻo Al₂O₃ calcined ma mua o 48% a me kahi haʻahaʻa Fe₂O₃ haʻahaʻa.

Hoʻohana Huahana

ʻO ka alumina refractory castable kiʻekiʻe he kūpono no ka umu hoʻomehana, ka umu ahi, ka umu hoʻomaʻamaʻa wela a me ka rotary kiln; ʻO nā linings kuni wela kiʻekiʻe, nā ʻāpana hoʻoheheʻe wai i ka umu ahi, nā ʻāpana o nā mea hana hoʻomaʻemaʻe ma waho o ka umu kila hoʻoheheʻe ʻia a me nā linings kūʻokoʻa wela o ka petrochemical catalytic cracking reactors; ʻO nā laina laina e like me ka blast furnace taphole, cupola taphole, integral powder gun for hot metal pretreatment, etc. Hiki ke hoʻohana ʻia e hana i nā poloka prefabricated nui a me nā linings umu no ka hana wikiwiki.
