Carbide plate Production Process

Tungsten Carbide plate Production Process 

Tungsten Carbide is a kind of material with high hardness, wear resistance, corrosion resistance and other excellent properties, widely used in metal cutting, abrasive processing, geological drilling and other fields. In the production and processing process of cemented carbide plate, there are many details and technical requirements that need to be paid attention to, the following will be detailed on the production process of cemented carbide plate.

Production process of cemented carbide plate:

The production process of cemented carbide plate mainly includes powder preparation, pressing, heat treatment, polishing and other processes.

Powder preparation

The powder preparation of cemented carbide sheet is the key to the whole production process. Tungsten carbide sheet is composed of tungsten, cobalt and other metals and carbides, prepared by ball milling method, powder particle size is finer. Among them, tungsten and carbon play a role in increasing hardness, and cobalt acts as a binder.

Press forming

After the powder preparation is complete, the powder is put into the mold for pressing and forming. During the pressing process, the powder needs to be compacted to reach a certain density for subsequent heat treatment.

Heat treatment

Heat treatment is an important link in the production of cemented carbide sheets. Vacuum heat treatment is usually used to treat the compressed powder at high temperatures to crystallize and cure it. After heat treatment, the hardness and wear resistance of cemented carbide sheet have been greatly improved.

polishing

By polishing, the finish and surface gloss of the cemented carbide sheet can be further improved. Polishing can use a variety of methods such as mechanical grinding and chemical polishing, but care needs to be taken to avoid excessive cutting resulting in surface damage.
