Your Professional High Alumina Refractory Materials and Refractory Bricks Manufacturer & Supplier !
Tabular alumina, also known as tabular corundum in China, is a pure, completely sintered alumina that is fired without any additives such as MgO and B2O3. The tabular corundum has a coarse, well-developed α-Al2O3 crystal structure. Since it is sintered at a temperature slightly lower than 2035℃, close to the melting point of Al2O3, the … Read more
High alumina bricks are made of bauxite that is crushed into particles, ground into powder above 180 mesh, and mixed with binders and water in different proportions. Then it is formed by a friction press, dried to remove moisture, and finally sintered at high temperature. Rongsheng High Alumina Refractory Brick Manufacturer. However, the quality of … Read more
Phosphate-bonded high alumina bricks are often used as lining materials in cement-coordinated waste incineration rotary kilns. Due to their good wear resistance, they can be used 2 to 3 times longer in the transition zone and cooling zone of the kiln than ordinary high alumina bricks. Rongsheng High Alumina Refractory Bricks Manufacturer provides high-quality high … Read more
Ladle lining refractory bricks, high alumina bricks for ladle, Rongsheng high alumina refractory bricks manufacturers. The typical inner wall of the ladle includes a fixed layer, a working layer, a slag line layer, and a heat insulation layer. The ladle insulation layer requires low thermal conductivity and good thermal insulation performance. The permanent layer requires … Read more
The selection of refractory materials for the ladle depends on the working environment of the ladle. The lining is either constructed with arc bricks or integrally constructed with aluminum silicon carbide castables. It’s just that the packages used are different and the construction methods are different. High Aluminum C-type Curved Ladle Brick. To improve the … Read more
How are refractory materials produced? What are the production processes of refractory materials? Depending on the density and shape of the product, there are sintering methods, melt-casting methods, and melt-injection methods. Among them, the melting and casting method involves mixing the raw materials and fine grinding, melting them at high temperatures, directly casting them, and … Read more
Wear-resistant ceramic balls (alumina balls) are now commonly used in two types: 92% and 95%. For some abrasives that are special and require high alumina content, it is recommended to use 95% wear-resistant ceramic balls. To purchase high-quality 95% wear-resistant ceramic balls and alumina balls, please choose Rongsheng Refractory Materials Manufacturer. The products are of … Read more
Alumina ceramics are special structural ceramics with the most mature industrialization technology, the largest production scale, and the widest application fields. Porcelain balls with an alumina content of more than 90% have the characteristics of high hardness, high density, low wear, corrosion resistance, and high-cost performance. As a grinding media, it is widely used in … Read more
As we all know, ball mill grinding is still the main method of cement grinding. The electricity consumption of cement grinding and the wear of metal grinding bodies such as steel balls and steel segments account for an important part of the cost of cement grinding. At present, the current situation of the cement industry … Read more
Can ceramic balls grind aluminum oxide and aluminum hydroxide? According to the experience of many manufacturers, alumina ceramic balls can grind aluminum oxide and aluminum hydroxide. Because of the high hardness of aluminum oxide and aluminum hydroxide, it is recommended to use ceramic balls with high content and heavy specific gravity. In this way, the … Read more
