Anti-stripping high alumina bricks are made of high alumina bauxite clinker, mullite, kyanite, zircon sand, and binder first through granulation and powdering processes, mixed in a certain proportion, then pressed into shape and fired at high temperature. Products with better anti-peeling properties. According to physical and chemical indicators, it is divided into two grades: GKBL-70 and KBL-70. Mainly used in cement rotary kiln, decomposition furnace, lime rotary kiln, nickel-iron rotary kiln and other kilns.

Anti-spalling high alumina bricks are fired products made of super high alumina bauxite clinker and ZrO2-containing synthetic materials, which are made by high pressure molding according to a certain proportion. Sodium, sulfur, chlorine and alkaline salt erosion, low thermal conductivity and other properties, it is an ideal material for the transition zone and decomposition zone of cement kilns. The notable features of the product are good thermal shock resistance and strong adaptability to the environment. It is mostly used in rotating preheating belts or in decomposition furnaces and grate coolers.

Performance advantages:

1. Reduce the temperature of the cylinder by more than 50 °C to ensure the safe operation of thermal equipment and reduce the phenomenon of red kiln.

2. Improve the heat utilization efficiency of rotary kiln, reduce energy consumption by more than 5%, and improve enterprise efficiency.

3. The overall performance is good, the effective use volume is larger than that of composite products, and the anti-wear cycle is long.

4. When the product is worn to half, the composite product will not be able to be used, while the heat-insulating silicon corundum brick can stick to the remaining one-third.

In order to maximize the effect of energy saving and consumption reduction of customer enterprises, our company has specially launched A and B types of heat-insulating silicon corundum bricks.

Type A is suitable for the transition zone and cooling zone of the rotary kiln, completely replacing the spinel bricks and siliceous red bricks commonly used by cement enterprises in this area.

Type B is suitable for the decomposition zone and preheating zone, and completely replaces the silica molybdenum bricks and anti-stripping high-alumina bricks commonly used by cement enterprises in this part.

Anti-stripping high-alumina brick is a new type of high-alumina material specially produced to solve the problem of cement kiln lining in my country. It has excellent thermal shock stability, high load softening temperature, high high temperature strength, alkali resistance and clinker erosion, high temperature Comprehensive characteristics of wear resistance, anti-peeling, anti-skinning, ringing and low thermal conductivity. Has been widely used in my country's new dry kiln, Li Boer kiln and wet kiln. The parts used include kiln door cover, rising flue, cooling belt, safety belt, transition belt, rear wall and side wall of cooler, and curved beam roof. It has been successfully applied in almost all kilns.

Components of anti-stripping high-alumina bricks:

Anti-spalling high alumina brick is a special product developed for alumina production clinker sintering belt.

Anti-spalling high alumina bricks are fired products made of super high alumina bauxite and ZrO2-containing synthetic materials, which are made by high pressure molding in a certain proportion. Erosion of sodium, sulfur, chlorine and alkaline salts, low thermal conductivity and other properties, it is an ideal material for the transition zone and decomposition zone of cement kilns, and can also be used for kiln door covers, coolers and other parts of cement kilns.

The alumina clinker kiln material has the characteristics of high temperature, high alkali and strong wear. The calcined material contains about 20% soda ash. The normal firing temperature is 1250-1360 degrees. In the past, ordinary clay bricks, high alumina bricks and phosphoric acid have been used. Salt combined with high alumina bricks is used as the lining, but because the load softening temperature of these refractories is too low or too high, or the thermal shock stability is too poor, or the wear resistance is not enough, the kiln skin cannot be hung, and the bricks will be seriously peeled off, Alkali corrosion and wear, so that the life of the kiln lining is only about 120 days, and the equipment operation rate is only 70-80%, which seriously restricts continuous production. Therefore, the rotary kiln lining must have good high temperature resistance and corrosion resistance. high strength and wear resistance, and should have excellent thermal shock stability in medium time.

Practice has proved that the service life of anti-peeling high alumina brick is more than 4 times that of clay brick NZ-40, more than 12 times that of steel bucket clay brick CN-40, more than 2 times that of blast furnace clay brick GN-42, and phosphoric acid. The salt-bonded high alumina brick is more than 4 times that of the imported kiln lining, which is more than 2.5 times.

Anti-stripping high-alumina brick is a new type of refractory material originally created in my country, reaching the international advanced level. This kind of brick has excellent physical and chemical indicators: thermal shock stability > 40 times at 1000 degrees, refractoriness of 1780 degrees, softening temperature under load of 1470 to 1520 degrees, low thermal expansion rate, small thermal conductivity, wear resistance and corrosion resistance, can Replace the refractory material of all parts except the firing zone of the large new dry kiln.

Application of anti-stripping high alumina brick: It is widely used in my country's new dry process kiln, Liboer kiln and wet process kiln. The parts used include kiln door cover, rising flue, cooling belt, safety belt, transition belt, rear wall and side wall of cooler, and curved beam roof.

The application of anti-stripping high alumina bricks in cement kilns is the rear wall and side wall of the caster cooler, the transition zone and the vicinity of the transition zone, the cooling zone, the decomposition zone, the kiln door cover, and the kiln mouth.

The application of anti-stripping high alumina bricks in the precalcining kiln system The decomposition furnace, smoke chamber and other parts extend from the end of the transition zone to the end of the kiln, according to the production characteristics of various kilns, until the alkali-resistant and heat-insulating bricks cannot withstand All parts are built with peeling high-alumina bricks.

Industrial experiments have proved that anti-stripping high-alumina bricks have the following characteristics:

Advantage:

Excellent thermal shock stability, high softening temperature under load, high high temperature strength, alkali resistance and clinker erosion, certain mechanical strength, high temperature wear resistance, peeling, resistance to skinning, ring formation, low thermal conductivity, long service life, etc. characteristic
