ʻO ka Magnesium ramming refractory mass kahi kiʻekiʻe o nā mea granular a me kahi haʻahaʻa haʻahaʻa loa o ka binder a me nā pūʻulu ʻē aʻe o ka ʻōnaehana hoʻolaha, a me nā ʻano huaʻai āpau, ka pauka, e hahau ʻia e ke ala o ke kūkulu ʻana i kahi ikaika. Hoʻohui ʻia ʻo Magnesia ramming mass e corundum, kiʻekiʻe kiʻekiʻe bauxite clinker, silicon carbide e like me ka aggregate, nā ʻano pauka āpau, ka pauka maikaʻi loa, ka micropowder, ka pauka alumina a me ka hoʻohui ʻana me nā ʻano hui like ʻole e like me nā ʻano like ʻole.
ʻO ka Magnesia ramming mass kahi ʻano o ka alkali amorphous refractory mea, i haku ʻia me ka electromagnet a i ʻole nā mea hoʻoheheʻe magnesia sintered, superfine pauda additive a me ka paʻa kemika. ʻO ka mua, hoʻomaʻemaʻe ʻia ke one magnesia kiʻekiʻe a me ka pauka magnesia no ʻekolu manawa e ʻae i ka hoʻonui piha ʻana a me ka ʻoki ʻana o ke one magnesia a me ka pauka magnesia. A laila hana ʻia ka ʻāpana o ka magnesia e like me nā koi hoʻolālā.
1. Hohola i ka mea ma lalo me ka mānoanoa o 100mm a 150mm a me ka rammedhard,
2. E hoʻomaʻemaʻe i ka ʻili, e hana hou i ka hana ramming
3. E kau i kahi ʻāpana kila ma luna o ka ʻili e pale aku i ka pōʻino ma ka ʻili i ka wā e kau ai i ka ʻōpala a me ka metala wela.

APP: Hoʻohana ʻia no ka umu ahi ahi hāmama no ka hoʻopiha ʻana i nā mea, ke kauoha ʻana i ka uhi a me ka hoʻopiha ʻana. |
Hiki ke hoʻohana ʻia ka refractory magnesia ramming mass e like me ka lining hou a i ʻole nā mea hoʻoponopono, e like me ka hoʻoponopono ʻana i lalo o ka hearth open, hoʻoponopono lining converter, a i ʻole nā mea hoʻopiha waha kila. A hoʻohana pū ʻia ka magnesium ramming mass i ka metallurgy, nā mea kūkulu hale, ka hoʻoheheʻe ʻana i ka metala nonferrous, ka ʻoihana kemika, nā mīkini a me nā ʻoihana hana ʻē aʻe.
ʻO ka hale hana refractory RS he mea hoʻolako nui i ka magnesium refractory ramming mass i hoʻokumu ʻia i nā makahiki 90 o iwakālua mau kenekulia. ʻO ka hale hana refractory RS he loea i ka magnesium ramming mass no nā makahiki he 20. inā loaʻa iā ʻoe kekahi koi o ka magnesium ramming refractory mass, a i ʻole he nīnau e pili ana i ka magnesia ramming mass e pili ana i nā hōʻailona kino a me nā kemika, e ʻoluʻolu e kelepona mai iā mākou no ka manuahi. a me Rs hale hana refractory ma ke ʻano he ʻoihana refractory magnesia ramming mass mea hana ma Kina, he mau pono hoʻokūkū e like me kēia:
