Product Description

Product Description:

Silicon carbide bushing is a new type of high-tech wear-resistant material in the world. It uses ≥95% silicon carbide as the main raw material, adds water, other inorganic substances, and binders to form a slurry, and is a composite high wear-resistant product made by sintering at a high temperature of 1700°C. The wear resistance in practical applications is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.

Silicon Carbide VS Alumina:

Silicon carbide ceramics not only has excellent normal temperature mechanical properties, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient but also high-temperature mechanical properties (strength, creep resistance) is the best known ceramic materials. Hot pressing sintering, pressureless sintering, and hot isostatic pressing sintered materials, their high-temperature strength can be maintained up to 1600 ºC, is the best high-temperature strength of ceramic materials. The oxidation resistance is also the best among all non-oxide ceramics. Alias emery.

Alumina ceramics is a ceramic material with alumina (Al2O3) as the main body, used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high-temperature resistance. The wear life of silicon carbide ceramics is more than 10 times that of traditional steel bushings and alumina bushings.

Silicon Carbide VS Steel:

In many mines and mining processes, the system of powder making, ash slag, dust removal, and slag conveying, the equipment is constantly affected by the friction, corrosion, collision, impact and other factors of the medium during the operation of the equipment. The earliest wear-resistant material that can be used in large quantities is mainly wear-resistant steel, wear-resistant cast iron and other metal materials. After that, the newest silicon carbide lined pipe appeared, which is superior to other wear-resistant materials in terms of wear resistance, corrosion resistance, practicability, and economy.

Another feature of silicon carbide bushings used in mines is small operating resistance loss. After testing the resistance characteristics of powder, slag, and ash, the results are as follows:

Ceramic-composite pipe	0.117	0.195	7.935×104	1.343×103	0.0193

Industry application:

Silicon carbide bushings are widely used in mining, ore crushing, screening, and transportation of high-wear and high-corrosive fluids. They are mainly used in copper mines, gold mines, iron ore, nickel mines and other non-ferrous metal mining equipment, use as a bushing, play a role of high wear resistance. Mine filling, ore concentrate and tailings transportation cause serious wear to the pipeline. The service life of the ore powder transportation pipeline used in the past is less than one year, and the service life of the silicon carbide bushing can be greatly improved.

Product Packaging:

We have two packaging methods, one is plywood box packaging, and the other is pure solid wood packaging. The pure solid wood packaging box will be certified for fumigation. We will choose the right packaging box according to the product.

The inside of the packing box is filled with foam. Generally, other companies use 2cm foam, but we choose 3cm foam and fix it with chain riveting. The outside is usually wrapped with packing tape to ensure the safety of product transportation.
Wear-resistant Product Recommendation:

Mining Industry Knowledge:

Selection criteria for silicon carbide lined pipes:
According to the nature of the conveyed materials and the different media conditions, it is important to choose products suitable for their own working conditions. When selecting wear-resistant materials, you must first determine your own working conditions, including the hardness of the conveying material, particle size, flow rate, conveying volume, conveying medium, etc., and then select the appropriate wall thickness silicon carbide wear-resistant material according to the specific situation.
