Model Number: 60 70 75 Brand Name: Baiyun Key Specifications/Special Features: Spinelintroduction:Fused magnesium aluminate spinel with a purity of 98.5% or more workers of alumina and a purity of 96% or more light burned magnesia and distribution into the right amount of high purity magnesite (MgO style > 47%), do cooperate, such as the Canon of high temperature in arc furnace togetherSpinelfeatures:Fusedmagnesium aluminate spinel has high temperature resistant, dense, bibulous rate is low, small thermal expansion coefficient, good thermal stability, strong ability to resist erosion characteristicsSpinel uses:Made of casting skateboard, nozzle bricks, ladle lining brick and brick is the ideal material of open hearth furnace, and large and medium-sized cement kiln cement kiln transition zone lining brick, refractory pouring and the basic materials of kiln furniture in high school
Widely used in steel smelting, cement rotary kiln, glass kiln, electric furnace top, ladle, and metallurgical industry
Spinelclassificationandapplication:
Syntheticspinel and fused two main methods are sintering method
Most spinel material is made from high purity synthetic chemical and alumina grade magnesium oxide, which in shaft kiln sintering and fused in arc furnace
Sintered spinel has the advantage of this process is a continuous process of pottery and porcelain, control the temperature of the furnace feeding speed and the equilibrium distribution, have very uniform crystal size of 30-80 microns and low porosity (< 3%) of the product
Fused method production spinel is representative of the intermittent operation, large casting piece need to extend the cooling time, in the microstructure of the casting block cool
