Good Chemical Stability Of Cemented Carbide Plate

Sep 01, 2017

Cemented carbide plate also known as cemented carbide plate, cemented carbide sheet material. Cemented Carbide is one of many materials, because its shape is rectangular plate (or square) and the name.

Cemented carbide plate is mainly composed of metal WC tungsten carbide powder and Co Co mixed with metallurgical method through milling, ball mill, pressing, low pressure sintering, Carbide Board product body compactness is good, no hole without sand holes, high precision (blank tolerance control in ±2.2~±2.2, fine billet control in ± 0.01), less processing allowance, Can effectively improve your productivity, significantly reduce processing costs.

Commonly used metal carbide is tungsten carbide, titanium carbide, niobium carbide and vanadium carbide, can make cemented carbide with high hardness and high wear resistance. Cemented carbide binder is mainly metal cobalt or nickel metal, can ensure that cemented carbide has a certain strength and toughness.

The main alloy components of cemented carbide plate are WC and co, Carbide Board and the content of WC and Co in cemented carbide plate with different uses is not consistent and the use range is very wide.

Production process of cemented carbide board

Flour milling → According to the requirements of the formula → by wet grinding → mixing → crushing → drying → sieving → after adding molding agent → again dry → Sieve after the preparation of mixed materials → granulation → pressure → molding → sintering → molding (rough) → inspection → packaging → storage.

Cemented carbide plate has excellent red rigidity, high hardness, good abrasion resistance, high elastic modulus, high compressive strength, good chemical stability (acid, alkali, high-temperature oxidation), Carbide Board low impact toughness, low expansion coefficient, heat conduction, conductivity and iron and its alloy similar characteristics.

Cemented carbide plate specifications are more, commonly used 100x100x5-30, 125x125x20, or 150x100x20-50 around. Carbide Board In accordance with the specific requirements of the customer size specifications, cemented carbide plate of the general stock is commonly used specifications.

The application of cemented carbide plate is mainly divided into three categories:

1, used to make blanking die. To be used in the production of copper, aluminum, stainless steel, cold-rolled plate, ei film, Q195, SPCC, silicon Steel, metal parts, standard parts, Carbide Board top and bottom punching the first-class thin-film high speed stamping die and multi-position progressive die.

2, used for making wear-resisting tool. such as woodworking industry with knives, plastic crushing tools.

3, for the production of high-temperature parts, wear-resistant parts, shielding parts. Carbide Board such as the Machine tool guide, automatic teller machine anti-theft strengthening board.

4, for the production of chemical industry corrosion-resistant parts.

5, for medical equipment, radiation and anti-corrosion materials.

6, different uses of cemented carbide plate material performance is not consistent, use should be specific to select the appropriate material for the use of cemented carbide plate.

Cemented carbide plate with excellent rigidity, high hardness, Carbide Board good abrasion resistance, high elastic modulus, high compressive strength, good chemical stability (acid, alkali, high temperature oxidation), low impact toughness, low expansion coefficient, heat conduction, Carbide Board conductivity and iron and its alloy similar characteristics, because the tungsten steel cutter has a great advantage, it is rapidly promoted in the industry. In the short span of 50 years, due to the use of tungsten steel knives, the metal cutting speed increased by 200 times times, Carbide Board from 10 meters per minute to more than 2-kilometer. The heat-resisting tungsten steel still retains good elasticity and mechanical strength, and is generally used for thicker cutting, discontinuous cutting and poor clamping of parts. After the coating effect is better, machinable to hrc50° of various materials. The corresponding general tungsten steel, with a few times the service life and excellent impact resistance.
