Cast basalt composite cross
Cast basalt composite cross - industrial steel product
Fused cast basalt linings provide superior protection against abrasion, erosion and chemical attack in demanding industrial applications.
Fused cast basalt linings are among the most durable and cost-effective wear protection systems available for industrial equipment handling abrasive materials. Produced by melting selected natural basalt at extremely high temperatures and casting the molten material into specially designed molds, these linings develop a dense microcrystalline structure that delivers exceptional hardness and outstanding resistance to abrasion, erosion, impact, and corrosion.
Fused cast basalt linings have been successfully used worldwide in mining operations, thermal power plants, cement factories, steel mills, ports, dredging systems, and chemical processing facilities where severe wear conditions can rapidly damage conventional steel components.
Fused cast basalt linings are wear-resistant lining systems manufactured by melting volcanic basalt at temperatures above 1250°C and subsequently casting the molten material into specific shapes. After controlled crystallization and annealing, the finished products achieve exceptional wear resistance and mechanical strength.
These lining systems are designed to protect equipment surfaces exposed to continuous contact with highly abrasive materials such as coal, ore, clinker, slag, fly ash, sand, gravel, limestone, mineral concentrates, and industrial slurries.
Compared with ordinary steel liners, fused cast basalt linings can provide several times longer service life while significantly reducing maintenance costs and production interruptions.
They are commonly used in industries that handle abrasive and corrosive substances, such as those involved in mining, cement production, power generation, and steelmaking.
Fused cast basalt linings offer several advantages over other types of lining materials, including:
High abrasion resistance: Basalt is one of the hardest naturally occurring minerals, which gives the cast basalt linings excellent resistance to wear and tear caused by abrasive materials.
Excellent chemical resistance: Basalt is also highly resistant to chemical attack, making it an ideal choice for environments where corrosive substances are present.
High temperature resistance: Fused cast basalt linings can withstand temperatures of up to 1000°C, making them suitable for use in high-temperature applications.
Easy to install and maintain: Cast basalt linings can be easily installed using a variety of techniques, including bolted, welded, or glued. They also require minimal maintenance and can last for several years before needing replacement.
Overall, fused cast basalt linings offer a cost-effective solution for protecting industrial equipment from abrasive and corrosive substances. They are durable, reliable, and provide long-lasting protection, which makes them an excellent choice for industrial applications where high wear resistance and chemical resistance are required.
Fused cast basalt engineered linings are abrasion-resistant and provide a long service life in the harshest conditions. ABRESIST is highly corrosion resistant and ideal for use with sewage, sludge, lime and limestone, dried sludge, and ash. This lining can be used in pipes, elbows, screw pumps, separators, cyclones, troughs, chain conveyors, and mixers, wherever abrasion is problematic.
Cast Basalt is made from special quality natural basalt. The basalt is melted in shaft furnaces at 1,300°C and then poured into the desired forms. Cast Basalt is produced in form components. Essentially, this means sheets and pipe components.
One of the most important processes in the production of Cast Basalt is the subsequent tempering during which the Cast Basalt forms a uniform crystalline structure that guarantees its high hardness and wear resistance.
Due to its bargain price/performance ratio, Cast Basalt is a material often used in tribology protection. In addition to its wear resistance, Cast Basalt is characterized by its singular resilience with regards to almost all acids and bases.
Cast Basalt surfaces remain permanently smooth and even while in use and thus offer the advantage of little caking.
