Processes of Cemented Carbide Plates

Tungsten carbide plate is one of the tungsten carbide products, and is named after the rectangular shape of the plate (or square), also known as tungsten carbide block. Tungsten carbide using metallurgical methods by making powder, ball milling, pressing, sintering, different uses of tungsten steel plate in the composition of WC and Co content is not the same, the use of a wide range of extremely good by hardness, high hardness, good wear resistance, high elastic modulus, high compressive strength, good chemical stability (acid, alkali, high temperature oxidation), low impact toughness, low coefficient of expansion, thermal and electrical conductivity similar to that of iron and its alloys.

Tungsten steel plates are mainly made of WC tungsten carbide and Co cobalt powder mixed by metallurgical methods of powder making, ball milling, pressing and sintering, the main alloy composition is WC and Co, the composition of WC and Co in different applications of tungsten steel plates are not the same, the use of a wide range.

The production process of Zhuzhou cemented carbide plate is as below.

Powder making→formulation according to the requirements of use→wet grinding→mixing→crushing→drying→sieving→then adding forming agent→drying again→sieving to make the mixture→granulation→pressing→forming→sintering→forming (blank)→flaw inspection→packaging→warehousing.
