Product Details
High Alumina Abrasive Castables Refractory
Description
High Alumina Abrasive Castables are monolithic refractory castables made from high alumina bauxite, refractory clays and other materials in a formulated proportional mix. These castables have excellent abrasion and wear resistance and are suitable for applications subjected to high mechanical and thermal stresses.
High Alumina Wear Resistant Castables are versatile refractory materials with excellent wear resistance, thermal stability and chemical inertness. They are widely used in industries that require a durable lining for equipment exposed to high temperatures, mechanical wear and corrosive environments.
Features
High strength and abrasion resistance
High alumina abrasive castable has high compressive strength and abrasion resistance, helping to maintain the integrity of the refractory lining and reduce maintenance costs.
Good resistance to thermal shock
High alumina abrasive castable is able to withstand rapid temperature changes without cracking or other damage, helping to extend the life of the refractory lining.
Good chemical resistance
High alumina abrasive castable is chemically inert and has good resistance to chemical attack by acids, alkalis and slag.
Easy to install
High alumina abrasive castable is easy to install and its shape can be adapted to the specific contours of the equipment being lined. It can be applied using a variety of techniques such as pouring, spraying and troweling.
Customizable formulations
The composition of High alumina abrasive castable can be customized to meet the specific requirements of different applications. This allows optimizing performance and cost-effectiveness for each specific use.
Low shrinkage
High alumina abrasive castable has a low shrinkage rate after installation and curing, helping to maintain the integrity of the refractory lining and reducing the risk of cracking or other damage.
Application
Steelmaking
High alumina abrasive castable is used in steelmaking for the interior walls of ladles, continuous casting tanks and other high-temperature equipment to protect against abrasion caused by molten steel and slag.
Non-ferrous metal production
High alumina abrasive castable is used in the production of non-ferrous metals such as copper, aluminum and nickel. High alumina abrasive castables are used in the lining of smelting furnaces and other processing equipment to protect against abrasion caused by molten metal and slag.
Cement production
High alumina abrasive castables are used in rotary kilns and other high-temperature equipment in cement production to prevent wear caused by raw meal and clinker.
Petrochemical and chemical processing
High alumina abrasive castable is used in process equipment in the petrochemical and chemical industries to protect against wear and corrosion caused by chemicals and high-temperature processes.
Power generation
High alumina abrasive castable is used in the power generation industry to line the interiors of boilers and other high-temperature equipment to prevent wear and tear caused by coal, ash and other combustion by-products.
