ʻOi aku ka nui o ka 90% o ka magnesium oxide i nā pōhaku magnesia a hoʻohana i ka periclase ma ke ʻano he crystalline nui. Hiki ke hoʻokaʻawale ʻia nā Bricks Magnesite i ʻelua mau ʻāpana o Burnt Magnesia Bricks a me Chemical Bonded Magnesite Brick. Loaʻa i nā pōhaku lepo Magnesite ka hana maikaʻi loa o ka ikaika mechanical wela kiʻekiʻe a me ka paʻa o ka leo. A hiki ke lawelawe i ka wela kiʻekiʻe o 1750 ℃, ʻo nā pōhaku lepo Magnesite nā huahana kūpono no ka noi ʻana i ka umu aniani.
Na waiwai o ka Magnesia Bricks
- ʻO nā refractorines kiʻekiʻe,
- ʻO ke kūpaʻa ʻana o ka palaka alkaline,
- ʻO ke kūpaʻa erosion a me ka anti-oxidation maikaʻi loa,
- ʻO ka refractoriness kiʻekiʻe ma lalo o ka ukana,
- Ka ikaika mechanical kiʻekiʻe,
- Paʻa leo ma ka wela kiʻekiʻe.
Ka Hana Hana Piliki Magnesia
Hiki ke hoʻokaʻawale ʻia nā pōhaku Magnesia i ʻelua mau ʻano: ʻo nā pōhaku magnesite kuni a me nā pōhaku magnesite paʻa kemika. Hana ʻia nā pōhaku lepo magnesite mai nā mea maka o ka periclase, ma hope o ke puhi ʻia ʻana me 1550 ~ 1600 ℃ wela kiʻekiʻe ma o ka ʻoki ʻana, ka hui ʻana, ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana. Loaʻa nā huahana maʻemaʻe kiʻekiʻe ma luna o 1750 ℃ wela wela. Hana ʻia nā brick magnesite unburnt me ka hoʻohui ʻana i nā mea hana kemika kūpono ma o ka hoʻoheheʻe ʻana, ka hoʻoheheʻe ʻana a me ka maloʻo.
Hoʻokaʻawale ʻia o nā Bricks Magnesia
Ma muli o ke ʻano kemika ʻokoʻa o nā pōhaku lepo magnesia, hiki ke hoʻokaʻawale ʻia i nā ʻano ʻano like ʻole, a ua hana ʻia kēia mau pōhaku āpau e ka sintering. Ma muli o nā ʻano mea like ʻole, hiki ke hoʻokaʻawale ʻia nā pōhaku magnesia i loko o nā ʻano like ʻole:
Pilikia magnesia maʻamau: pōhaku magnesite sintered.
Pilikia magnesia pili pololei: magnesite sintered kiʻekiʻe.
Pilikia forsterite: peridotite
Pilikia calcia Magnesia: magnesite sintered i loa'a ka calcium ki'eki'e.
Pilikia silika Magnesia: pōhaku kiʻekiʻe kiʻekiʻe i hoʻopaʻa ʻia i ka magnesite.
Pilikia chrome Magnesia: magnesite sintered a me kekahi oka chrome.
Pilikia alumina Magnesia: pōhaku magnesite sintered a me Al2O3.

Hoʻohana ʻia nā Piliki Magnesia no ka umu ahi
He kūpono nā pōhaku magnesite no nā ʻano umu wela wela, e like me nā kapuahi metala. Eia kekahi, hoʻohana nui ʻia nā pōhaku magnesia i nā mea wela ʻē aʻe, e like me ka hyperthermia tunnel kiln, ka uhi ʻana o ke kīwī sima rotary, ka umu wela i lalo a me ka paia, ke keʻena regenerative o ka umu aniani, ka umu uila lalo a me ka paia a pēlā aku.
Mea Hana Piliki Magnesia ma KinaM
ʻO ka mea hana refractory RS he mea hana ʻoihana magnesia bricks ma Kina, hiki ke hāʻawi i nā pōhaku magnesite kiʻekiʻe no ʻoe. Inā makemake ʻoe i nā pōhaku lepo magnesia, a i ʻole he nīnau e pili ana i nā pōhaku magnesia e pili ana i nā hōʻailona kino a me nā kemika, e ʻoluʻolu e kelepona mai iā mākou no ka manuahi, e hoʻopili koke kā mākou kūʻai aku iā ʻoe.
