ʻO nā pōhaku kalapona Magnesia, mākaukau no ka hoʻouna ~

Hoʻolauna
Hana ʻia nā pōhaku lepo kalapona Magnesia me ka helu hoʻoheheʻe kiʻekiʻe kumu oxide magnesium oxide (kahi heheʻe 2800 ℃) a me kahi mea hoʻoheheʻe kiʻekiʻe e paʻakikī i ka pulu ʻana e ka slag e like me nā mea maka, a ua hoʻohui ʻia nā ʻano mea hoʻohui non-oxide. ʻO ia kahi mea hoʻopaʻa kalapona i hui pū ʻia me kahi mea hoʻopili kalapona. Hoʻohana nui ʻia nā pōhaku kalapona Magnesia no ka uhi ʻana o nā mea hoʻololi, AC arc furnaces, DC arc furnaces, a me ka laina slag o nā ladles.

Ma ke ʻano he mea refractory composite, hoʻohana maikaʻi ʻo magnesia carbon brick i ka ikaika o ka pale ʻana i ka ʻōpala o ke one magnesia a me ke kiʻekiʻe thermal conductivity a me ka hoʻonui haʻahaʻa o ke kalapona, e uku ana i ka pōʻino nui loa o ka pale ʻana o ke one.

Nā hiʻohiʻona:
1. Paipai wela kiʻekiʻe
2. Ka ikaika o ka slag
3. ʻO ke kūpaʻa haʻalulu wela maikaʻi
4. Haʻahaʻa kiʻekiʻe wela kolo

Noi:
1. ʻOihana Metallurgical

Ma ke kahua o ka hao a me ke kila metallurgy, magnesia carbon brick ua hoʻohana nui ʻia no ka uhi ʻana o nā kapuahi hoʻoheheʻe wela kiʻekiʻe e like me nā ladles, nā mea hoʻololi, nā umu uila, a me nā mea pale refractory no nā waha slag like ʻole, pallets, coke nozzles, ladle uhi, etc. ʻAʻole wale nā ​​pōhaku kalapona Magnesium e hōʻoia i ka hopena kemika maʻamau kiʻekiʻe a me ka hana mau ʻana i ka umu, akā pū kekahi hoʻonui nui i ke ola lawelawe o ka umu hoʻoheheʻe a hoʻemi i nā kumukūʻai mālama.

2. ʻOihana kemika

I loko o ka ʻoihana kemika, hoʻohana nui ʻia nā pōhaku kalapona magnesia i ka lining, ka pale kinoea a me ka uhi ʻana o nā ʻano reactors wela kiʻekiʻe, nā mea hoʻololi, a me nā umu ahi. Ke hoʻohālikelike ʻia me nā pōhaku lepo refractory kuʻuna, ʻaʻole ʻoi aku ka maikaʻi o ke kūʻē ʻana o ka wela kiʻekiʻe i nā pōhaku kalapona magnesia, akā loaʻa nō hoʻi ke kiʻekiʻe kalapona maʻiʻo a me ka conductivity uila maikaʻi, hiki ke pale pono i ke ahi ahi.

3. Nā ʻoihana ʻē aʻe

Ma waho aʻe o nā kahua metala a me nā kemika, hoʻohana nui ʻia nā pōhaku kalapona magnesia i nā kapuahi hoʻoheheʻe wela kiʻekiʻe, nā umu uila, nā gantries a me nā locomotives kaʻaahi ma nā kula o ka ʻaila, metallurgy, a me ka mana uila.
