Kaha Kiʻekiʻe Kiʻekiʻe Cement Corundum fireclay Refractory Insulation Castable
Noi: Ka uhi o ka umu hoohehee alumini
ʻO ka ʻenehana hoʻoheheʻe ʻana i ka umu ahi metallurgical kahi ʻano hana hoʻoheheʻe i hoʻohana ʻia e hoʻolei i nā mea refractory no ke kino umu i ka manawa hoʻokahi.Aia nā hiʻohiʻona o kēia ʻenehana i kona kūpaʻa kūpono, ʻaʻohe hui pōhaku, a me ka ikaika holoʻokoʻa kiʻekiʻe, no laila he lōʻihi ke ola o ke kino umu.E ho'āʻo i kēia ʻenehana ma kekahi mau kino kapuahi i loko o ka ʻoihana metala non-ferrous.ʻO ke kiʻekiʻe o ka mahana hana o ka umu pōʻai e like me 1200 ℃, a ʻo ka mahana hana o ka umu static e like me 1000 ℃.Hoʻohana ʻia ka umu pōʻaiapuni i ka umu i ka wehe ʻana a me ka hānai ʻana, ʻo ka umu liʻiliʻi ka wehe ʻana i ka slag manual me nā puka umu ʻekolu, a ʻo ka umu nui ka hana wehe ʻana i ka slag me ʻelua mau puka umu.ʻO nā mea maka he alumini ingots, scrap cast bars, scrap profiles and cast-rolled aluminum coils.Loaʻa i kēlā me kēia kapuahi paʻa nā puka umu ʻelua no ka hana ʻana a me ka hoʻomaʻemaʻe ʻana.I ka wā ma mua, ua hana ʻia ke kino o ka umu ahi i nā pōhaku lepo refractory, a ua maʻalahi kekahi mau ʻāpana, no laila e pili ana i ke ola a me ka hana pono o ke kino umu.I ke kūkulu ʻia ʻana o ka pūnaewele Zhengzhou, ua ninini ʻia ka umu hoʻoheheʻe alumini me nā castables refractory e hoʻomaikaʻi i ke ola lawelawe holoʻokoʻa o ke kino umu.
