Do you Want to Know These Knowledge about Fused Magnesia Brick?

The fused magnesia brick has the advantages of compact brick structure, high mechanical strength and low impurity content. It is mainly used for heat storage dense refractory bricks of large glass kiln. The refractory material has certain shape and size. The unit volume and weight are large, indicating dense. Goodness, the strength may be high, also called the high temperature load to start the deformation temperature, called the reheating line change or the residual line change, refers to the change of volume expansion and contraction in the same temperature change each time, high temperature resistance, about 1800 degrees, load The softening temperature is 1620-1640, and the coefficient of thermal expansion is small.

 

Dense refractory brick is a kind of siliceous clay rich in hydrated aluminum silicate. It has the ability of no deformation, no fragmentation, no softening and no paste at high temperature. There are many kinds of refractory bricks in the amorphous material sector. For product consumption, the basic quality requirements are alumina higher than 38% and low iron and low alkali metal content. These products may not be calcined or calcined, such as refractory clay, plastic for overload, high alumina plastic, refractory clay and high oxidation. Aluminum castables, etc.

Magnesia brick refers to non-fired refractory products made of aluminum bauxite clinker and magnesia as raw materials. With the development of new steelmaking technologies such as oxygen blowing in converters, continuous casting and refining outside the furnace, the increase in molten steel temperature and the prolonged residence time in the ladle make the conditions of the lining of Shenggang barrels harsh, resulting in clay-lined bricks. The erosion is serious, and the use of the lining brick has a good effect. The steel drum is not burned. The aluminum-magnesia brick is made of aluminum bauxite clinker and magnesia. Burning refractory products. With the development of new steelmaking technologies such as oxygen blowing in converters, continuous casting and refining outside the furnace, the increase in molten steel temperature and the prolonged residence time in the ladle make the conditions of the lining of Shenggang barrels harsh, resulting in clay-lined bricks. The erosion is serious, and the use of the lining brick has a good use effect.
