Cast basalt slab
Premium cast basalt slabs, designed for long-lasting performance in severe conditions.
Cast stone liners for slag dredgers provide superior wear protection in thermal power plant ash and slag conveying systems exposed to severe abrasion and erosion.
A cast stone slag dredger liner is a wear-resistant lining plate installed inside slag extraction equipment to protect structural steel components from severe wear. The liner is manufactured by melting selected natural basalt rock at temperatures exceeding 1250°C, followed by casting, crystallization, and annealing to create an extremely dense microcrystalline structure.
The resulting material offers hardness approaching that of industrial ceramics while maintaining superior toughness and impact resistance compared with many traditional lining materials.
These liners are particularly suitable for wet bottom ash handling systems, submerged scraper conveyors, slag extraction channels, and ash sluicing systems commonly used in thermal power stations.
Cast stone liner for slag dredger in thermal power plant is a lining material that is used to protect the dredger from the harsh conditions of operation in a thermal power plant. The slag dredger is an important component of the power plant's slag handling system, which extracts solid waste material from the furnace and transports it to a disposal area.
The cast stone liner is usually made from a dense, high-strength concrete material and is designed to withstand the abrasive and corrosive effects of the slag material being transported by the dredger. It is typically installed inside the dredger's hopper, where it provides a durable surface that can withstand the constant impact and wear caused by the abrasive slurry flowing through it.
The cast stone liner is an integral part of the slag dredger system and helps to ensure the efficient and reliable operation of the power plant's slag handling system. Its use can help to reduce maintenance and repair costs associated with the dredger, and can also help to improve the overall efficiency and reliability of the power plant's operations.
Protects equipment against abrasive slag, ash, clinker, and mineral particles.
Resists acidic and alkaline environments present in ash-water systems.
Lasts several times longer than ordinary steel wear plates.
Minimizes shutdown frequency and lowers operating costs.

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
