Corundum Castable

ʻO ka mea maka o ka corundum castable ʻo ia ka corundum keʻokeʻo, fused corundum a i ʻole corundum brown. No ke ʻano o ke ʻano o nā mea maka i hoʻohana ʻia e like me ka aggregate, pono e hui pū ʻia nā ʻāpana me nā ʻāpana ʻokoʻa like ʻole, a me nā ʻāpana corundum coarse, nā ʻāpana liʻiliʻi a me ka pauka e loaʻa nā ʻano kūpono, a laila hui pū ʻia me nā mea hoʻohui Qihe (silica micropowder, water reducer a pahū-hōʻike fiber), pono lākou e hoʻohui ʻia i nā mea maka a hoʻopiha piha ʻia.

Hana Huahana

Ke hoʻohālikelike ʻia me ka alumina kiʻekiʻe a me ka mullite castable, ʻoi aku ka ikaika o ka corundum castable a me ke kūpaʻa ʻana, akā ʻaʻole maikaʻi kona kūpaʻa haʻalulu wela e like me ka mullite castable. ʻO ka hoʻohui ʻana i kahi nui o ka mullite i loko o nā mea maka hiki ke hoʻomaikaʻi i ke kūpaʻa haʻalulu wela o ka corundum castable. Loaʻa i ka corundum castable ka ikaika compressive kiʻekiʻe a me ke kūpaʻa hoʻolālā maikaʻi. Nui ka mana, corundum castable castable lining he slag corrosion resistance, permeability resistance, high wear resistance and strong resistance to solid particles, powder and high temperature gas erosion.
