High Alumina Ladle Refractory Brick for Steel Industry
The Description:
The mineral composition of high molybdenum steel clad brick is corundum, mullite and glass phase, and its content depends on the AL203/ SIO2 ratio and the type and amount of impurities, which can be classified according to the AL2O3 content. The raw materials are high bauxite and sillimanite natural ores, and there are also electric fused corundum, sintered alumina, synthetic mullite, and clinker calcined with alumina and clay in different proportions. It is produced by sintering method. But there are also fusible cast bricks, fused granular bricks, unfired bricks and amorphous ladle bricks. High aluminum ladle brick is widely used in iron and steel industry, non-ferrous metal industry and other industries. Zhengzhou Zhenjin Refractory Co., Ltd. is located in Xinmi City Song Lou Industrial zone, legal representative Song Jinbiao, the company was founded in the 1980s, is a professional building materials industry with refractory research and development, production and sales as one of the high-tech enterprises, is the key listed backup enterprises in Zhengzhou City, Zhengzhou hundred high growth private enterprises, the 60th anniversary of the founding of Henan Province building materials Industry's most influential enterprises.
