High-alumina refractory bricks are made from bauxite or kaolinitic clays. The definition high-alumina refractory bricks contain between 50 and 87.5 percent alumina. They are much harder and tougher than fireclay refractories at high temperatures and in basic environments.
Phosphate High Alumina Bricks (also called Phosphate Bonded High Alumina Bricks) are a kind of new type environmentally friendly refractory, composed of normal refractory and light weight insulation refractory to meet the daily production requirements and save costs on coal and powder of users.
High Alumina Refractory castable(also called High Alumina Castable) is made of high alumina bauxite as clinker, refractory clay as powder.
Mullite Refractory Bricks (also called mullite bricks) are made of synthetic fused mullite or sintered mullite, pressed by selected shaping processes, and fired in high temperature furnaces. Mullite refractory bricks offer high density, low porosity, good hot strength, and good slag resistance.
Andalusite bricks have high cold crushing strength, high refractoriness under load, high thermal stability, good creep resistance and thermal shock resistance. It is alternative product for high aluminum bricks, used in the professional of the key parts of the furnaces.
Chrome Corundum Refractory Brick is kind excellent high temperature material, it contains 33~90% of Al2O3 and 10~66% of Cr2O, mixed in a certain proportion, and made of special refractory production technology.

Refractory Bubble Alumina Ball (also called Refractory Hollow Alumina Ball, or Sphere Alumina Refractory), Bubble Alumina balls and likely products are light refractories with high temperature resistance and excellent energy saving, which are very stable in various atmospheres.
Calcined Kaolin Material (also called Kaolin Clay or Chamotte) is an essential industrial mineral primarily made up of the mineral kaolinite – a hydrous aluminum silicate. Kaolin can be found in applications all around us, from consumer products, to advanced industrial processing.
High Alumina Raw Materials (also called bauxite or flint clay) are used to improve the performance of refractories by imparting properties such as strength, protection from chemical and physical attack, and slag resistance.
The heat storage ball is an indispensable energy storage material for high-temperature industrial kilns. It is used as a medium for heat storage and release in high-temperature processes. It is generally used in the combustion chamber and heat exchange area of the kiln to absorb and release heat, thereby improving the thermal efficiency and stability of the kiln. These balls can help the kiln use heat energy more effectively under high-temperature conditions, thereby reducing energy consumption and improving production efficiency. The amount of aluminum in the heat storage ball generally affects its refractory temperature, compressive strength, creep resistance, and other physical and chemical indicators. So how much aluminum does the general heat storage ball contain? At present, the main materials of heat storage balls are high-aluminum heat storage balls and corundum heat storage balls. Their aluminum content is also different. The more common aluminum content is 65%, 70%, 75%, 85%, etc. According to the different aluminum content, their refractory temperature and creep resistance are different. At the same time, the price of heat storage balls with different aluminum content is also different. The higher the aluminum content, the more expensive the price, so we should choose according to the actual...
The maintenance of refractory castables is a crucial step after the kiln is cast. Good maintenance can ensure that the kiln has a good working performance after it is put into use, and it can also increase its service life. During maintenance, the refractory castable can gradually reach the design strength while avoiding quality problems such as cracking and delamination. Next, let the editor take you to understand in depth why refractory castables need to be maintained: 1. Improve the strength of refractory castables Through proper maintenance, refractory castables can reach the design strength in a shorter time, ensuring that the refractory castables have sufficient refractoriness and wear resistance after being put into use. 2. Prevent refractory castables from cracking After the refractory castables are put into production, the rapid high temperature will cause thermal expansion of the refractory castables. If the maintenance is not in place, the internal moisture cannot be fully volatilized, and the refractory castables are prone to cracking. Therefore, oxidation before the initial production can allow the moisture in the refractory castables to fully volatilize, which can effectively reduce the occurrence of cracks. 3. Prevent refractory castables from falling off During the maintenance process of refractory...
The reduction of refractory castable strength can easily lead to the peeling and slag falling of the high-temperature kiln as a whole. In severe cases, it can even lead to the collapse of the kiln as a whole. There are many reasons for the reduction of castable strength. It may be a problem in the early construction or a problem of improper operation in the later stage. Therefore, the specific reasons are analyzed in detail. Today, the editor will introduce some common reasons for the reduction of castable strength: 1. Water-cement ratio is too high: ash ratio refers to the ratio of water to raw materials. If the water-cement ratio is too high, the moisture content in the refractory material will be too high, resulting in the overall fluidity of the refractory castable being too strong, and the whole will become loose, resulting in reduced strength. Therefore, in the process of adding water, water must be added strictly according to the water addition ratio. 2. Refractory material quality problem: If the quality of the refractory castable is too low, or too many foreign impurities are mixed in during the construction process, the overall strength of the refractory castable will be...
The T3 model represents the brick number of refractory bricks, also known as standard bricks. Its size is generally the most basic size of refractory bricks and is also the most widely used size of refractory bricks. The size of refractory brick T3 is 230mm×114mm×65mm, which is a standard rectangular block, representing its length, width, and height respectively. Its volume is generally 1704.3 cm3, which is one of the most common sizes of refractory bricks. T3 refractory bricks are straight refractory bricks, which are often used for the masonry of some conventional walls, such as some rectangular and square high-temperature kilns and other regular walls. In the masonry of some irregular walls, there are many other brick numbers and sizes of refractory bricks that can be used, so when masonry, it is necessary to select according to the masonry diagram in the drawing. At present, in addition to T3 refractory bricks, there are also common refractory brick sizes such as T38, T20, and T46, which are all used for the construction of refractory walls of different shapes and structures. There are thousands of sizes of refractory bricks according to the refractory brick size table. When choosing the size of refractory...
Hollow alumina balls are a high-temperature insulation material that can be made into various refractory and insulation products. The maximum use temperature is 1800℃. The products have high mechanical strength and low volume density. They are lightweight, hard, high temperature resistant, and corrosion resistant. The following will introduce some of the main applications of hollow alumina balls. 1. Hollow alumina balls are widely used in the field of filling materials Because hollow alumina balls have a low specific gravity and low thermal conductivity, they have good insulation properties, and can effectively reduce heat conduction and improve insulation effects, so they are often used in various insulation products, such as insulation surface layers, insulation wall panels, and insulation pipes. 2. Alumina hollow balls are also used to prepare lightweight materials Because alumina hollow balls have the characteristics of low volume density and high compressive strength, they are often used to make fillers for some lightweight composite materials. While reducing the weight of the product, the strength can also be guaranteed. By mixing alumina hollow balls with other basic materials (such as polymers, rubber, etc.), lightweight composite materials such as automotive parts, aerospace components, and sports equipment can be prepared. 3. Alumina...
