Lightweight Brick Introduction：Lightweight brick generally refers to foamed brick, which is made of high quality plate corundum and mullite as aggregate, composite silicalite as matrix, special additives and a small amount of rare earth oxide, and then molded by high pressure and fired at high temperature. Ordinary lightweight brick contains clay brick, high aluminum high strength drift bead brick, low iron mullite brick, high aluminum poly light thermal insulation brick, diatomite thermal insulation brick, etc. Industrial kilns use lightweight bricks with low thermal conductivity and small heat capacity as the structural material of the furnace body, which can save fuel consumption; at the same time, because the kiln can quickly heat up and cool, it can improve the production efficiency of the equipment; it can also reduce the weight of the furnace body. Simplify the kiln structure, improve product quality, lower the ambient temperature, and improve working conditions. Lightweight Brick Advantage：1, Economy: Lightweight brick can reduce foundation cost. Compared with solid clay brick, using light brick can decrease overall cost.2, Practicality: Using lightweight brick can increase application area, and insulation effect can be better.3, Application property: lightweight brick has good processability, easier for construction. This brick is larger and lighter, can make construction work higher efficient, then shorten the construction period.

High alumina bricks introduction:High alumina bricks are refractory products of aluminum silicate or alumina with Al2O3 content greater than 48%. High alumina bricks are mainly used for laying blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kiln linings. High alumina bricks can be said to be one of the most widely used refractory bricks in the refractory industry. High alumina bricks are mainly divided into ordinary high alumina bricks and modified high alumina bricks. Ordinary high alumina bricks refer to commonly used standard fired bricks, while modified high alumina bricks mainly refer to: high load soft high alumina bricks, micro-expansion high alumina bricks, low creep high alumina bricks and phosphate bonded high alumina bricks. High alumina bricks advantages: The high alumina brick has high density, low porosity, high mechanical strength and wear resistance, high softness of load, and good slag resistance. High Alumina Bricks Application: Lightweight high-alumina bricks are currently one of the ideal heat-insulating refractory materials. They have the characteristics of high compressive strength, low thermal conductivity, good insulation performance and low price. They are now widely used in Taoist kilns and roller conveyors. Kilns, shuttle kilns, and wall kilns are not used in various heating furnaces, coke ovens and other thermal equipment in the steel industry to heat treat lining materials. Lightweight high alumina bricks are also called high alumina insulation bricks. A lightweight refractory material with an alumina content of more than 48%, mainly composed of mullite and glass phase or corundum. The bulk density is 0.4-1.cm3, the Confucius Institute rate is 66%-73%, and the compressive strength is 1-8MPa. Usually, a small amount of clay is added to the high-alumina bauxite material, after grinding, it is poured into mud by the gas production method or foam method, and then fired at 1550-1600°C. Sometimes industrial alumina can be used to replace part of the bauxite treatment. It is used in the inner and warm layers of masonry kilns, and the parts that are not strongly eroded and eroded by high-temperature molten materials. When in direct contact with the flame, the surface contact temperature should not be higher than 1400°C.

Anchor Brick Introduction:The anchor brick for the heating furnace is suitable for the top and the furnace wall of the heating furnace. The production of anchor bricks mainly needs to consider two aspects: one is the refractoriness, and the other is the tensile strength. The production of anchor bricks pays more attention to the cold tensile strength of anchor bricks, and the production is also prosperous using raw materials that are easy to sinter to make bricks. Anchor brick is a kind of anchor brick for industrial kiln, also known as hanging brick and anchor. It is formed by press molding or pouring molding and then high temperature sintering. The structure and masonry of the trough-shaped anchored brick hanging form are relatively simple and easy to replace. In order to avoid the high temperature of the I-beam hanging from the anchor bricks, the upper surface of the anchor bricks is not allowed to be installed with a heat insulation layer, so the heat dissipation capacity of the furnace roof is relatively large. The hanging form of anchored bricks with wrong teeth has the advantages of good interlocking integrity and good airtightness. Even if the individual bricks are broken, they will not fall. Anchor Brick Advantages:Anchor brick for heating furnace has long service life with high refractoriness and tensile strength, prevents damage or falling off during exercise. Anchor bricks have many advantages such as good erosion resistance, good spalling resistance, high strength, and basically the same thermal expansion as the castable of the furnace lining. Our factory can provide customers with professional customization.
