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.
During the construction process, low cement castables must be constructed according to the requirements of the construction drawings. According to the technical requirements of the drawings, the furnace steel structure, baselines, holes, and other parts should be comprehensively and carefully inspected and accepted. Check the side wall insulation layer bricks and anchor bricks. The shape and size of the anchor bricks and hanging bricks should be inspected and accepted piece by piece. There should be no transverse cracks. The position of the bricks should meet the design requirements and keep the anchor hooks with the furnace shell. Or the furnace ceiling hanging beams are vertical. To prevent the side wall lightweight insulation bricks from absorbing water, a layer of asphalt should be painted on their surface. It is necessary to check whether the inner mold is firmly supported and cannot be moved. The surface should be wrapped with cloth; the template should also be firmly supported and the surface should be brushed with oil to facilitate demoulding. Check whether the mixer, vibrator, etc. are working normally; and whether the driving is normal. If a failure occurs, repair it in time or prepare other hanging equipment. You must ensure that pouring...
Aluminous Cement, also known as high alumina cement or calcined aluminate cement, is a special refractory cement made from ores (such as kaolin, bauxite, gangue, etc.) and calcined at high temperatures. The main component of aluminate cement is calcium aluminate (CA), which has a high aluminum oxide (Al2O3) content, usually between 40% and 70%. Aluminate cement has the following characteristics 1. Shorter initial and final setting times: Compared with ordinary Portland cement, aluminate cement sets faster and can reach a certain strength in a short time, which is beneficial to shorten the construction period. 2. Suprior high-temperature performance: Aluminate cement has high fire and heat resistance, and can maintain stability and mechanical properties in high-temperature environments. Therefore, it is often used in refractory materials and high-temperature equipment. 3. Chemical corrosion resistance: Aluminate cement has good acid resistance, alkali resistance, salt-resistance, and corrosion resistance, and is suitable for use in chemical, petroleum, and other industries where chemical corrosion may occur. 4. Thermal shock resistance: Since aluminate cement has a low thermal expansion coefficient, it can better resist thermal stress when temperature changes and has strong thermal shock resistance. 5. Anti-permeability: Aluminate cement has good anti-permeability, which can effectively prevent the penetration...
An aluminum melting furnace is a device used to heat and melt aluminum materials. It is usually used in casting metallurgy, manufacturing aluminum alloys, and other fields. 1. After starting the heating furnace of the aluminum melting furnace, adjust the heating parameters until they heating parameters are stable before normal heating production can be carried out. 2. Before starting the aluminum melting furnace, you must check whether the pushing and discharging devices, circulating water, and air pressure are normal, whether the limit switch, manual and automatic switch positions are in the required positions, check whether the materials on the workbench meet the requirements for forgings, and you must always pay attention to it. Cooling water, because cooling water is the lifeline of the induction furnace, the outlet water temperature must not exceed 60°C. 3. The aluminum melting furnace should be placed correctly during the charging process. All large pieces of aluminum need to be processed before being installed in the furnace, and attention needs to be paid to the method. The irregular side should be placed as upward as possible to avoid jamming the furnace lining. 4. When the aluminum melting furnace is first fired in the cold furnace, the...
Castable prefabricated parts generally refer to a special-shaped refractory workpiece that is cast in advance. Its main use is in some special parts or difficult-to-construct parts during the construction of high-temperature kilns. By placing these externally in the early stage the production of refractory materials with special shapes can not only reduce the difficulty of construction but also speed up the construction progress during the construction process and ensure the construction quality. Generally speaking, the shapes of prefabricated parts are all kinds of strange, and they are usually customized according to the actual conditions of use. Since they are cast through molds, they can be made into prefabricated parts of various sizes and shapes, which are more precise than machine pressing. Greater complexity, mass, and volume. 1. Raw materials for castable prefabricated parts The raw materials of castable prefabricated parts are generally proportioned according to the actual use conditions. Currently, common raw materials include high aluminum, clay, corundum, silicon carbide, and other raw materials. They are professionally prepared according to the actual use temperature and use environment. The proportions are then added, poured into the mold, air-dried, and finally calcined at high temperature to make the finished product. 2. Characteristics...
Industrial square aluminum melting furnace is a common aluminum melting equipment in the aluminum melting and casting industry. It can well meet the requirements of strict alloy composition, discontinuous production, large single furnace capacity, and other requirements in the green smelting industry, thereby reducing energy consumption. To ensure the stable operation of the aluminum melting furnace, the selection of refractory castables for each part in the initial construction is very important, so the square aluminum melting furnace How to choose the appropriate refractory castable for the furnace? Next, the editor will help you to understand. First of all, we need to understand the overall structure of the square aluminum melting furnace. Since the temperatures generated during the production process are different in different parts, different castables must be selected in different parts when selecting. The overall structure of the industrial square aluminum melting furnace includes: The furnace top, upper furnace wall, furnace door, furnace bottom and lower furnace wall, furnace door frame and surroundings, burner, and burner, its structure diagram is shown in the figure below: In the above structure, appropriate refractory castables must be selected according to different working conditions.
