Carbide plate, also known as carbide plate, carbide sheet. Is one of the many materials of cemented carbide, because of its shape for the rectangular plate (or box) and named.
Carbide plate mainly by the 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), Carbide Board 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 binder is mainly metal cobalt or metal nickel, etc., to ensure that the carbide has a certain strength and toughness.
Carbide alloy main alloy composition for the WC and Co, different uses of cemented carbide plate in the WC and Co composition of the content is not consistent, Carbide Board 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 adding 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 plate properties
Carbide plate 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, Carbide Board conductive and iron and its similar characteristics of the alloy.
Carbide plate application range
Carbide plate application is divided into three categories:
1, for the production of blanking die. Carbide Board It should be used in the production of punching copper, aluminum, stainless steel, cold rolled sheet, EI sheet, Q195, SPCC, silicon steel sheet, hardware, standard parts, upper and lower punch and other high-speed die and multi-station progressive die.
2, for the production of wear-resistant tool. Such as woodworking industry with tools, plastic crushing tools.
3, for the production of high temperature parts, wear parts, anti-shielding parts. Carbide Board Such as the machine guide rail, ATM anti-theft board, and so on.
4, for the production of chemical industry corrosion-resistant parts.
5, for medical equipment, radiation and anti-corrosion materials.
6, different uses of carbide plate material performance is not consistent, Carbide Board the use of specific use should be based on the choice of appropriate material carbide plate.
