Kiln Boiler High Alumina Refractory Bricks Thermal Stable Insulating Fire Brick - China

Good Thermal Stability High Aluminum Refractory Fire Bricks for Kiln and Boiler Product Description 1 - The characteristics of high aluminum brick is good thermal shock resistance, strong corrosion resistance, high compressive strength.

2 - The brick lines containing Al2O3 in 48% to more than 75% of the aluminum silicate, belongs to the refractory material of weak acid, it is made of natural or artificial high alumina raw materials (sillimanite, diaspore, high alumina) aluminum products made of refractory materials, high refractoriness, high compressive strength and softening temperature.

3 - The slag resistance and compressive strength is larger.

For laying steel smelting boiler, ladle boiler, blast boiler and so on.

Technical Parameters - - - - High-alumina Brick QRL-65 Physical and Chemical Indexes | AL2O3, % | 65-75 | refractoriness | 790 | 0.2MPa softening temperatureRUL, | 1500 | Reheating linear change rate (1500 degrees *2h) | -0.4--0.1 | Apparent Porosity AP, % | 21 | Cold Crushing Strength CCS, Mpa | 80 | Volume Density BD, g/cm | 2.7 | Creep rate% (1350*50h)0.2Mpa | 0.8 | - - - - 4 - Mainly used for masonry blast furnace, hot stove, electric stove roof, blast furnace, reflector furnace, rotary kiln lining.

In addition, high alumina bricks are also widely used as hearth regenerative plaid bricks, plugs used in casting systems, nozzle bricks, etc.

5 - High alumina brick and clinker clay brick production process is similar, the difference is that the proportion of ingredients in a higher clinker can be as high as 90 to 95%, clinker before sorting and sorting should be selected iron removal, firing temperature higher.

Factory Photo Focus on the achievement of quality, Professional to create the future.
