Ceramic Fibre Bulk
Ceramic fiber bulk is a high-temperature refractory fiber made of high-purity raw materials through high-temperature melting, using blowing or spinning technology. The fiber has good chemical stability and can resist the erosion of most aggressive chemicals. Even if the finished product is wetted by oil, water or steam, its physical properties such as temperature resistance and heat insulation will not change. Fiber cotton can be further processed into fiber blanket, felt, board, paper, cloth, rope and other products.

Calcium Silicate Board
Calcium silicate board, also called asbestos-free calcium silicate board, is a white, hard thermal insulation material.
The raw materials of calcium silicate board are siliceous materials (quartz powder, diatomaceous earth, etc.), calcareous materials (cement, lime, etc.), and reinforcing fibers, which are made through processes such as pulping, blanking, steaming and curing, and surface sanding of lightweight panels.

Stainless Steel Anchor
Stainless steel anchors are mainly used to fix the integrated thermal insulation board and integrated board, increase the force area of the screw, and make the wood board and the wall stronger. Applicable temperature range: 800-1400°C.
The stainless steel anchor is a structural component used to connect and fix lightweight refractory materials (such as ceramic fibers, lightweight insulation bricks and unshaped refractory materials) with the metal siding of the furnace. According to the structure of the industrial furnace, the temperature of the furnace and the surrounding environment, anchors with different structures and materials should be selected.

Magnesia Hercynite Brick
Magnesia hercynite bricks have the advantages of chromium-free environmental protection, good thermal shock stability, good kiln skin hanging ability, good corrosion resistance, low thermal expansion and low thermal conductivity, and better structural flexibility. In practical applications, the brick has a service life of more than 1 year, the kiln skin is hung quickly in the firing zone, the thickness of the kiln skin is uniform and stable, the refractory bricks have no large flaking phenomenon, and there is no flaking phenomenon of refractory bricks when the kiln is stopped. The temperature of the kiln barrel is low, and the heat energy less loss.

Fused Cast AZS Block
Fused cast AZS block manufacturing process mixes selected zircon sand and industrial alumina powder at a ratio of 1:1, plus a small amount of Na2O (added in the form of sodium carbonate), B2O3 (added in the form of boric acid or borax) flux, and mix well After being melted at 1800~1900℃, it can be cast to form a fused-cast brick containing 33% ZrO2. On this basis, using partially desiliconized zircon sand as raw material, fused-cast bricks containing 36% to 41% ZrO2 can be produced. Zirconium corundum bricks use industrial alumina powder and selected zircon sand as raw materials to produce refractory products with a ZrO2 content of 33% to 45%.
Fused cast AZS block is an important refractory material to ensure the normal operation of glass melting furnaces. At present, glass melting furnaces increase the melting rate, extend the life of the furnace, and reduce fuel consumption mainly due to the use of this refractory material. -
Al2O3-SiC-C Brick
AI203-SiC-C brick, referred to as ASC brick. AI203-SiC-C brick is made of fused corundum (or sintered corundum, special grade bauxite clinker), graphite and silicon carbide with fixed carbon above 90%-95% as the main raw materials. It is made by adding graphite, bauxite, and additives, after batching, forming, drying and high temperature firing. ASC brick has very good high temperature performance and anti-oxidation, anti-flaking and anti-slag erosion properties, can withstand long-term high-temperature solution erosion, and has a long service life.

Calcium carbide
Calcium carbide is an inorganic compound, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc. Physical and chemical properties: The ore is a yellowish-brown or black blocky solid, and the pure product is a white crystal (the one with higher CaC2 is purple). It has a density of 2.22 g/cm3 and a melting point of 2300°C (related to the content of CaC2). It immediately reacts violently when it meets water to generate acetylene and release heat. The melting point changes with different calcium carbide content.

Bauxite
The main component of bauxite is alumina, which is hydrated alumina containing impurities and is a kind of earthy mineral. White or off-white, brownish yellow or light red due to iron content. Density 3.45g/cm3, hardness 1~3, opaque and brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid and sodium hydroxide solution. Mainly used for smelting aluminum and making refractory materials.
The composition of bauxite is extremely complex, and it is a general term for a variety of hydrous alumina ore with extremely different geological sources. Such as boehmite, diaspore and gibbsite (Al2O3·3H2O); some are composed of diaspore and kaolinite (2SiO2·Al2O3·2H2O); some are mainly composed of kaolinite and follow The increase in the content of kaolinite constitutes general bauxite or kaolinite clay. Bauxite is generally formed by chemical weathering or exogenous effects. There are few pure minerals, and always contain some impurity minerals, more or less clay minerals, iron minerals, titanium minerals and detrital heavy minerals. -
Chamotte
Chamotte is a high-quality hard refractory clay produced in Zibo, Shandong Province, China.

The composition is stable, the texture is uniform, the structure is dense, and the section is shell-shaped and white. It is used to produce high-quality clay refractory materials. The technical term is the first-grade hard clay clinker, the main chemical components are AL2O3 and SiO2, accompanied by a small amount of Fe2O3 and trace amounts of Na2O and K2O. The main mineral is kaolin.
The chamotte we call generally refer to CALCINED CLAY. . The content of Al2O3 in the calcined chamotte is about 44%, and the content of Fe2O3 is not more than 2%. The composition is stable, the texture is uniform, the structure is dense, and the section is shell-shaped.
The common colors of chamotte after high temperature calcination are: pure white, light gray, light yellow brown, and a small amount of brown iron sheet.

Andalusite
Andalusite is an aluminosilicate mineral, which is the raw material for making refractory materials and porcelain in spark plugs. It is a typical mineral of low-grade thermal metamorphism, and is commonly found in mudstones in contact with metamorphic zones. It is mainly formed under the conditions of high geothermal gradient and low pressure to temperature ratio.
Andalusite is generally columnar crystal, and its cross section is almost square. Andalusite crystals gather together into radial or granular shapes. People often call the radial andalusites “chrysanthemum stones”, which means that they are like the petals of a chrysanthemum.
