Your Professional High Alumina Refractory Materials and Refractory Bricks Manufacturer & Supplier !
The red color of the surface of high-alumina bricks mainly comes from various factors during the firing process. In the sintering process, the placement of the brick blank is very important. If the brick blank is at the fire head position, the upper position, or the temperature adjustment is unstable during sintering, it is very … Read more
As the name implies, anchor bricks are mainly used for anchoring. They are carefully designed and placed in the lining structure of the furnace to firmly fix the refractory materials so that they can withstand extreme conditions such as high temperature, chemical erosion, and mechanical stress. During the operation of the furnace, anchor bricks can … Read more
99.99 high purity alumina balls, also known as super wear-resistant alumina ceramic balls, are a kind of high purity alumina material. It has the characteristics of extremely high purity, excellent wear resistance, good corrosion resistance, high density and low water absorption. Its alumina content reaches 99.99%, and other contents are at PPM level, ensuring the … Read more
When I asked AI, “What is tabular alumina?” its answer was: Tabular alumina is a high-purity aluminum oxide material with the following characteristics: High purity: Al2O3 content exceeds 99%, with almost no impurities. Crystal structure: It has a well-developed α-Al2O3 crystal structure, the α-Al2O3 crystals are coarse, and the median diameter is mostly 40~200μm. Porosity … Read more
The main reason for the industrial use of andalusite is its high temperature resistance. When andalusite is heated to 1350°C under normal pressure, it begins to transform into needle-shaped mullite parallel to the original crystal. Mullite crystal is the only stable form of aluminosilicate under high temperature, and its theoretical conversion rate is 87.64%. Processing … Read more
The composition and application fields of tabular corundum. Tabular corundum is corundum that is not smelted in an electric furnace. It is made of smelted alumina (Al2O3 content of more than 85%), which is wet-milled into a 3-micron micro-particle slurry (a binder should be added during ball milling), and then pressed into various geometric shapes … Read more
In the acidic environment of the push plate kiln, acid-resistant refractory materials need to be selected to protect the kiln body from corrosion and high-temperature damage. Rongsheng Refractory Material Manufacturer can provide high-quality acid-resistant refractory materials for the 800-degree acidic working environment of the push plate kiln. The push plate kiln is a kiln used … Read more
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
