Product Description

$White Corundum Brick for Garbage Incinerator by Xinmi Insulation and Refractory Material$

Xinmi insulation and refractory material factory high quality white corundum brick for Garbage incinerator

Corundum bricks refer to refractory products with alumina content higher than 90% and corundum as the main crystal phase. Very high normal temperature compressive strength (up to 340MPa).

High load softening start temperature (more than 1700°C). Very good chemical stability, strong resistance to acidic or alkaline slag, metal and glass liquid. Thermal shock stability is related to its structure. The corrosion resistance of compact products is good, but thermal shock stability is poor.

There are two types of sintered corundum bricks and fused corundum bricks. Sintered alumina and fused corundum can be used as raw materials, or bauxite clinker with high Al2O3/SiO2 ratio can be combined with sintered alumina and made by sintering method. Phosphoric acid or other binders can also be used to make non-fired corundum bricks.

Mainly used in iron-making blast furnaces and blast furnace hot-blast furnaces, refining furnaces outside steel-making furnaces, sliding water heaters, glass melting furnaces, and petrochemical industrial furnaces.

The properties of corundum bricks: It has good resistance to carbon reduction stability at high temperatures. By reducing the porosity of corundum bricks and reducing the content of SiO2 impurities, the performance is significantly improved. Therefore, the anti-reduction ability of pure corundum refractories is better than corundum bricks combined with corundum and mullite. Under the action of solid carbon at 1750℃, the weight loss of dense corundum bricks of pure corundum is 7.20%, and that of high-density corundum bricks is 1.86%. The special dense corundum brick is 1.12%. The apparent porosity of corundum refractories increases, and the weight loss also increases proportionally. Within 200h at 1600°C, no signs of corundum refractory being reduced by solid carbon were found. This and some other properties have become a set of pure corundum refractory materials used in high-temperature operation of the coke oven partition wall lining, as well as the production of pitch coke and other carbide furnace lining promising refractories. The corundum refractory has a very stable effect on melting aluminum (including in a vacuum), so the corundum refractory can be used as a crucible and furnace lining for melting aluminum.

Manufacturing Technique

$White Corundum Brick for Garbage Incinerator by Xinmi Insulation and Refractory Material$

Xinmi insulation and refractory material factory high quality white corundum brick for Garbage incinerator

1.The corundum brick Production Process
Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment

Properties of corundum bricks
Corundum bricks are widely used in blast furnaces and hot air stoves in metallurgical industry, second-stage furnaces, gasifier, gasifier, cracking furnace, ceramic, building materials, military industry, scientific research and other industries.The corundum bricks on various kilns are subject to high temperature, high pressure, slag and strong reducing gas erosion and damage in addition to being restricted by various technological conditions.This kind of chemical erosion and structural damage to corundum bricks reduces the service life of corundum bricks.

Chemical reaction of the high temperature of alumina, alumina melting point is 2050 ℃, alumina and other oxide reaction at high temperature after the formation of the melting curve, there is a downturn in the melting temperature only chrome oxide and alumina can form a continuous solid solution, the solid melting zone between the two kinds of oxide melting point.

The main impurities in corundum bricks are silicon dioxide and iron oxide.In Al2O3 - SiO2 - FeO ternary system phase diagram, the lowest melting point is 1205 ℃, which formed in more than 1200 t can glass phase. Titanium oxide and niobium oxide can reduce the melting point of alumina products and also be the sintering AIDS.In the sintering process, alumina is mixed with titanium oxide and niobium oxide to form aluminum titanate or aluminum niobate. 1% of titanium oxide or niobium oxide is added into alumina.

Vanadium pentoxide is a low melting oxide.At low temperature, the boundary dissolution of aluminated aluminum crystals occurs and the grains are dissected.And vanadium pentoxide and CaO under oxidizing atmosphere, generate calcium vanadate of low melting point (618 ℃), under the weak reducing atmosphere generated volatile calcium vanadate. The destructive effect of vanadium pentoxide on corundum brick is to produce vanadium pentoxide precipitate between corundum grain in corundum brick, which causes cracking, and then produces structural crack and large scale flaking.

With sodium sulfide erosion of corundum brick is in the process of gas coagulation of sodium oxide in 1000 ℃ can erode corundum brick.The post-al2o3 in corundum was transformed into p-al2o3, which caused the volume of the brick to expand greatly (about 26%) and caused the corundum brick to crack and peel off the epidermis.

Na2O and SO3 under 1000 ℃ can react with sillimanite and mullite, to generate the gray stones and beta Al2O3, volume increases by about 86%, peeling, split brick.
