Description:

Machine Pressed Refractory High Alumina Bricks is a kind of alkali refractory bricks, the cement kiln block can also be synthetized as spinel, which is made into an amorphous refractory used for integral structures and internal lining. The production process of magnesite refractory bricks is basically in phase with the production process of common magnesia brick, However, each level of granule in the batching component is composed of a sintered synthetic spinel or an electrically fused spinel, or a mixture of the two.

Machine Pressed Refractory High Alumina Brickscan be divided into three process: Raw material, molding, burning.Generally, Machine Pressed Refractory High Alumina Bricks was molded by dry pressing. By means of mixing the material uniformity in proportion and aging mixture some time. Then, pour some powders into the module and dry pressing. After dry pressing, the adobe need to pushed in the drying kiln to stoving or stay in the air to drying. This progress will need about 3-5 days. After this progress, then push the adobe into the tunnel furnace or shuttle kiln to burning around 1300C. This progress will be need about 5-7 days.

Machine Pressed Refractory High Alumina Bricks is an ideal insulating refractory refractory material, with advantages of high strength, low thermal conductivity, good insulation property and low price. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

Feature

1. It has advantages with small bulk density, high cold crushing strength, and high refractoriness under load, small dimension tolerance and good thermal shock resistance.
   2. It has the lowest and most stable thermal conductivity in various insulating refractory bricks.
   3. It can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained.

Applications

1. Furnaces of metallurgy industry, heat treatment furnace

2. Furnaces of chemical industry and construction industry.

3. Furnace of incineration of garbage, recirculating fluidized bed furnace
