High Alumina Castable
Products Description
High alumina castable is available in different grades that come with varying alumina content. The grades range from 35% to 99% alumina. The product has excellent thermal shock resistance, high compressive strength, and low porosity. Additionally, it has high abrasion and spalling resistance, making it perfect for high-temperature applications.
Products Features
High alumina castable aluminum content is usually between 50% and 90%, and the specific content can be adjusted as needed.May contain other additives such as silicate, magnesium salt, etc. to improve the properties of the material.
Density: Typically between 2.5g/cm³ and 3.0g/cm³.
Compressive strength: can be designed according to requirements, generally between 50 MPa and 150 MPa.
Refractory resistance: up to 1700°C to over 1800°C.
Common shapes include lumps, lump granules or powders. Specifications and sizes can be customized according to customer needs. For example, blocks may have different lengths, widths, thicknesses, etc.
Products Process
high alumina castable is made from high-quality raw materials and processed using advanced manufacturing techniques.
1. First graded and weighed accurately to achieve the desired composition.
2.Then mixed with water to form a slurry, which is cast into molds to achieve a specific shape.
3.The product is then dried to a specific temperature and cured over a specified period.
Products Advantage
High temperature resistance: High alumina castables have excellent refractory and high temperature resistance, can maintain stability in high temperature environments, and can withstand temperatures up to 1700°C to over 1800°C.
Excellent wear resistance: This material usually has high wear resistance and can withstand wear and thermal shock at high temperatures, extending the service life of the material.
Corrosion resistance: High-aluminum castables have strong resistance when in contact with acid, alkali and other chemical corrosive substances, and can maintain the stability of the material.
Good thermal conductivity: It usually has good thermal conductivity, which helps to evenly distribute temperature and heat and improve the efficiency of the furnace.
Ease of application: High-aluminum castables are typically supplied in block, granular or powder form and are easy to mix, fill and pour onto surfaces that require maintenance or fire resistance.
Highly customizable: Manufacturers can adjust the formula and material composition according to specific application needs to meet the requirements of different industrial furnaces.
Stable chemical properties: High alumina castables have high chemical stability, can resist chemical reactions and corrosion, and maintain structural integrity.
