Cast basalt process

Natural gas is used for melting basalt stone in melting furnace. Natural gas is currently very clean and environmentally friendly fuel. No any pollution. To the customer requirements choose environmental protection material that is a good choice.

The product processed from cast basalt is a new type of silicate crystalline material. Using natural rock (basic database, shale, etc.) or industrial waste as the main raw material components, smelting, casting, heat treatment and other processes are regularly arranged, crystalline, hard, and fine-textured metal industrial materials. Casting basalt has an excellent high abrasion and high resistance. Abrasiveness. Corrosion resistance.

Its main products include cast basalt pipes, cast basalt lining, steel pipes, cast basalt tiles and cast basalt powder.

Cast basalt products have been widely used in the fields of industrial abrasion and corrosion. These industries are set up as follows: power, coal, mining, metallurgy, chemical industry and construction. Our cast basalt products can make the life of parts or equipment longer.

Due to the poor toughness and high hardness of cast basalt products, processing is difficult. Products are generally processed according to shape and size.

Wear-resistant composite fittings production

Wear-resistant composite fittings are made of steel pipes or steel plates (the material is usually determined according to customer needs and working conditions), lined with wear-resistant layers (including cast stone, aluminium oxide ceramics, silicon carbide, wear-resistant steel, etc.) Composed of layers (plaster or cement).
The technological level of steel production is an important factor to ensure the strength of wear-resistant composite products. The welding process and the group have higher requirements on the process.
After the steel pipe is welded, the welding quality inspection and dimensional inspection can be carried out before entering the next process.

Filling and maintenance

According to the different filling methods, composite pipes are usually divided into the following three forms
1. Casting—cast the cast stone magma or wear-resistant molten steel directly between the inner and outer layers of steel plates, and then anneal and cure.
2. Composite — lining the steel parts with wear-resistant products, bonding and fixing them with cement or cement.
3. Welding or bolting.


Filling refers to the process of fixing the wear-resistant material in the steel. The filling is required to be firm, without voids; the curing is complete; the maintenance is sufficient.


Maintenance, Sheet lining – use wear-resistant cement to bond ceramic sheets, cast stone slabs, etc. to steel parts
