Sintered magnesium aluminum spinel products aftermarket instructions

? Feature

Sintered magnesium aluminum spinel has good resistance to erosion, abrasion resistance, thermal shock stability. Its main purpose: First, instead of magnesium chrome sand production of magnesium aluminum spinel brick for cement rotary kiln, not only to avoid the pollution of chromium and has a good anti-peeling; the second is used to make ladle castable, greatly improve the steel Lining resistance to erosion. Making it widely used in refractory materials for steelmaking. The preparation of high quality pre-synthetic spinel provides new raw materials for the production of amorphous and shaped high purity refractories.

First, sintered magnesium aluminum spinel packaging, logo, transport, storage and quality certificate: 1, the sintered magnesium aluminum spinel packaging, marking, transportation, storage and quality certificate according to YB / T5142 provisions. 2, sintered magnesium aluminum spinel transport must be clean, and there are rain, snow facilities. Spinel transport process must be protected against moisture and pollution, so as not to affect product quality. 3, sintered magnesium aluminum spinel must be stored in a dry, ventilated from the wet of the Treasury, to avoid the phenomenon of damp caking, affecting the use and performance.

Refractory brick is called fire brick. Refractory materials made of refractory clay or other refractory materials. Pale yellow or brownish. Mainly used for smelting furnace, the resistance of 1,580? -1,770? high temperature. Also called fire brick. A refractory with a certain shape and size. According to the method and method can be divided into firing brick, not burning brick, fused brick (cast brick), fire insulation brick; according to the shape and size can be divided into standard brick, ordinary brick, Can be used as building kilns and a variety of thermal equipment, high temperature building materials and structural materials, and at high temperatures can withstand a variety of physical and chemical changes and mechanical effects. Such as refractory clay brick, high alumina brick, silica brick, magnesia brick and so on.

Own attribute 1, chemical composition: the main ingredients determine the quality and characteristics of the refractory 2, the bulk density: weight per unit volume, density, indicating good density, strength may be high, but the thermal conductivity may be large Refractory bricks Refractory bricks 3, was porosity: did not do specific requirements, but as a manufacturer must strictly control the hole was. 4, load softening temperature: also known as high temperature load began to deformation temperature, this parameter is very important, marking the material resistance to high temperature resistance 5, thermal shock resistance: the rapid changes in temperature without the ability to damage 6, compressive strength: to withstand (room temperature) the maximum pressure capacity 7, bending strength: the ability to withstand shear pressure 8, the linear rate of change: also called the re-burning line changes or called the residual line changes, that each time in the same temperature changes in the volume of expansion and contraction changes, if each expansion contraction, we define such a linear rate of change of 0 Physical and chemical properties 1, wear resistance: 2, thermal conductivity: unit temperature gradient conditions, through the material per unit area of??the heat flow rate, with the porosity 3, impact resistance: do not explain it, impact resistance is good, long service life 4, slag resistance: at high temperatures to resist the role of slag erosion and not be destroyed
