Carbide is a refractory metal hard compounds and bonded metal through the powder metallurgy process made of an alloy material. Carbide has a high hardness, wear resistance, strength and toughness is good, heat, corrosion and a series of excellent performance, especially its high hardness and wear resistance, even at 500 ℃ temperature is basically the same , At 1000 ℃ still have a high hardness. Carbide is widely used as a tool material, such as turning tools, cutter, planer, bit, boring tool, etc., for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel, can also be used to cut Heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult to process materials.

Carbide material products

First, carbide plate

Carbide sheet, also known as carbide plate, carbide sheet. Is one of the many materials of cemented carbide, because of its shape as a rectangular plate (or box) named.

Carbide sheet is mainly made of metal WC tungsten carbide powder and Co cobalt mixed with metallurgical method by milling, milling, pressing, low pressure sintering, the product body compactness, no holes without trachoma, high precision (rough tolerance control In the ± 2.2 ~ ± 2.2, billet control in ± 0.01), less processing margin, can effectively improve your production efficiency, significantly reduce processing costs.

Commonly used metal carbide is tungsten carbide, titanium carbide, niobium carbide and vanadium carbide, etc., can make carbide with high hardness and high wear resistance. Carbide adhesive is mainly metal cobalt or metal nickel, etc., to ensure that the carbide has a certain strength and toughness.

Carbide sheet main alloy composition for the WC and Co, different uses of cemented carbide sheet WC and Co in the composition of the content is not consistent, the use of a very wide range.

Second, the production process

Milling → according to the requirements of the recipe → by wet grinding → mixing → crushing → drying → sieving → after the addition of molding agent → re-drying → after the preparation of the mixture → granulation → pressing → forming → sintering → forming (rough) → inspection test → packaging → storage.

Third, the characteristics of carbide material properties

Carbide sheet has excellent red hardness, high hardness, good wear resistance, high elastic modulus, high compressive strength, good chemical stability (acid, alkali, high temperature oxidation), low impact toughness, low expansion coefficient , Thermal conductivity, conductive and iron and its similar characteristics of the alloy.

Fourth, the use of tungsten steel materials are as follows:

1, tungsten steel made of high-quality tungsten steel, tungsten steel is extremely high hardness and brittle, vulnerable to external shocks, especially tungsten steel slitting blade thickness is thin, by the external boxing is more likely to break Therefore, when the installation of various tungsten steel materials used to prohibit beating, throwing tungsten steel material.

2, tungsten steel material edge is extremely sharp, please pay special attention when installing safety, so as to avoid unnecessary personal injury.

3, tungsten steel production series of tungsten steel products are particularly wear-resistant, its life is high-speed steel (white steel) several times, can greatly enhance your work efficiency and thus reduce your costs.

4, tungsten steel material has a very high hardness, so its processing is particularly difficult, feasible processing methods are as follows:

A, EDM (in the alignment, walking wire, fast wire processing)

B, welding processing: brazing, silver welding processing.

C, grinding: unintentional grinding, within the round grinding, grinding plane, tool grinding processing, the use of grinding wheel is generally diamond grinding wheel, depending on the specific process requirements.

D, laser processing: can be laser cutting forming, drilling, but the thickness of the cutting by the laser power constraints
