Refractory Bricks Manufacturer

In 1983, Japan used the non-burning Al2O3-SiC-C refractory material that can meet the needs of modern torpedo-type hot metal ladle trucks and ladle, which triggered a world revolution. Aluminum-carbon bricks belong to the range of aluminum-carbon refractory materials. The so-called aluminum-carbon refractory material refers to the carbon made by bonding alumina raw materials and carbon raw materials, in most cases, other raw materials, such as silicon carbide, metal silicon, etc., with organic binders such as pitch or resin. Composite refractory material. Broadly speaking, the refractory with Al2O3+C as the main component is called aluminum-carbon refractory. According to the production process, aluminum-carbon refractories can be divided into two categories: unburned aluminum-carbon refractories and fired aluminum-carbon refractories. The performance characteristics are strong corrosion resistance, good thermal shock stability, high strength, and high thermal conductivity. So, how mu...

The petrochemical industry incinerator is an intermittent working kiln, and the lining mainly uses high alumina bricks, refractory castables, refractory plastics, etc. The working environment of the incinerator is harsh, and the inner lining is damaged by various chemical erosion, physical erosion, and mechanical stress. High-Quality High Alumina Bricks for Sale Refractory materials used in incinerators in the petrochemical industry have higher requirements than general industrial kilns. Not only must it withstand high temperatures, but it must also have excellent corrosion resistance, wear resistance, and high-temperature stability. In the petrochemical refining industry, tail liquid vertical incinerators are more common. The main operating mechanism of the incinerator is to oxidize and burn the toxic organic matter in the petrochemical tail liquid, convert it into harmless gas and then empty it. Under the normal atomization condition of the tail liquid nozzle of the incinerator, the...

The glass melting furnace is the heart of the float glass production line. The service life of the glass melting furnace mainly depends on the corrosion and burning degree of the wall of the melting furnace, the dam, and the regenerator. The corrosion degree of the pool wall is the key part that affects the life of the furnace. The batch material is heated by the high-temperature radiation of solids passing through the flame along the longitudinal direction of the furnace. The first stage is the silicate reaction between various components in the raw material. The second stage is the unreacted foamy silicate ballast. The third stage gradually melts into molten glass. Na2O penetrates into the interior from the glass phase and pores of the wall tiles by means of penetration, diffusion, and substitution, and the protective layer is lost under the action of the temperature erosion of the glass liquid and the flow of the glass liquid. Alkaline oxide is the main factor causing the erosion of...

At present, the construction methods of refractory insulation materials for the melting part of the glass furnace and the top of the regenerator can be divided into two types: cold insulation and hot insulation. Rongsheng Refractory Mortar for Sale The characteristic of refractory insulation materials is to reduce heat dissipation, improve the thermal efficiency of the furnace, and at the same time ensure the life of the furnace. After the refractory insulation material is used for heat preservation, the temperature of the outer surface of the main body brick will be greatly increased, which requires that the quality of the main body brick must be good, and high-quality refractory mortar must be used. This kind of refractory mortar should have a certain degree of cohesiveness at room temperature so that the bricks will be more firmly bonded during the baking process, and the bricks will not sink or "drop off". Only in this way can the insulated furnace be in good operating c...

Acid-resistant and refractory castables are made of water glass or cement as a bonding agent, mixed with siliceous and aluminum silicate materials. Its characteristic is that it still has good performance under the action of medium and low temperature and acid medium. This type of refractory castable is applied to equipment such as the protective layer of the ball top of the blast furnace hot blast stove, the steel chimney lining, and other equipment, and obtains a better use effect. Acid-resistant Refractory Castable Performance and Application of Acid-resistant Castable Acid-resistant castable is an acid-resistant material combined with water glass. The combination of water glass can reduce the amount of Na2O and improve acid resistance. The acid resistance of this type of castable is affected by both physical and chemical effects. When the concentration of the acid solution is small, it will penetrate along the fine cracks of the product. The connection between aggregate and powder ...

High temperature resistant and corrosion resistant zircon brick s are made of zircon as the main raw material, added with binders and additives, equipped in proportion, and fired at high temperature after mixing, mixing, molding, and drying. Also called sintered zircon brick. Zircon bricks are divided into the high-density type and dense type according to production technology and physical and chemical indicators. RS Zircon Refractory Bricks for Sale Sintered Zircon Brick for Glass Kilns Sintered zircon bricks for glass kiln are mainly used for the working layer of the wall of the glass kiln. Its density is high, and as a working layer of the pool wall, it has a strong ability to resist the corrosion of glass liquid. In recent years, the world's glass industry melting furnaces have developed in the direction of large-scale and energy-saving. The dense zircon brick with high density and low porosity is a special type suitable for the lining of the glass furnace melting pool for glas...

Acid-resistant castables have better acid resistance and are used in metallurgy, electric power, and chemical kilns. Acid-resistant castable ( https://www.hy-refractory.com/products/unshaped_refractory/acid-resistant-castable.html ) for a chimney is a new type of anticorrosive castable. It has good workability, convenient construction, and a moderate initial setting and final setting time. After high-temperature baking, the strength continues to increase, and the impermeability and acid resistance is not reduced. But acid-resistant castables have poor resistance to hydrofluoric acid and high fatty acids. Acid-resistant Castable Acid-resistant castables are castables that can resist acid corrosion at a temperature of 800-1200°C. Acid-resistant castable is a castable mixed with acid-resistant aggregate, powder, water glass, or phosphoric acid as a binder. The acid-resistant castable also has strong anti-corrosion performance, which can meet the requirements of acid corrosion and the fati...
