Cemented Carbide Plate Production Process And Equipment

Cemented Carbide Plate Production Process And Equipment 

Cemented carbide plates, with their excellent physical properties such as high hardness, wear resistance and corrosion resistance, are widely used in mold making, aerospace, machining and other fields. Its production process integrates advanced material science and precision manufacturing technology, in which key technological links and equipment such as spray drying, deep cold treatment, SHIP low-pressure sintering and cold isostatic pressing play a vital role.

Raw material preparation

The main raw materials for cemented carbide are tungsten and cobalt powders, which need to be crushed, screened and dried first to ensure the purity and homogeneity of the raw materials. Powder preparation. Tungsten and cobalt powders are mixed according to a certain ratio, and add a small amount of metal oxides and other additives, and then after ball milling and other mechanical treatment to make the mixture uniform. 

Mixing

The powder and organic plasticizer are mixed to make a paste suitable for press molding. Pressing. The mixture is placed in a press and high pressure is applied to shape it. Commonly used pressing methods include isostatic pressing, cold isostatic pressing, hot isostatic pressing, and extrusion.

Sintering

The pressed and shaped carbide blanks are placed in a high temperature furnace and sintered under hydrogen or nitrogen protective atmosphere to form a dense alloy. Post-treatment. After sintering, the Cemented Carbide blanks need to be drilled, ground, molded and other subsequent processing processes to achieve zui final specifications and precision requirements.

Spray dryer

Ensure the homogeneity and fineness of the raw material powder to provide high quality raw material for the subsequent processes.

Cold isostatic pressing machine

through high pressure, the powder is pressed into blanks with a certain shape and density to ensure the density and performance of cemented carbide plates.

SHIP Low Pressure Sintering Furnace

Realize mutual diffusion and combination of powder particles at high temperature to form a solid cemented carbide structure and ensure the performance and quality of cemented carbide sheets.

Deep cooling treatment equipment

to improve the microstructure and properties of Cemented Carbide plates, such as improving hardness, wear resistance and dimensional stability.

Zhuzhou Jinxin can produe all kinds of tungsten carbide plates. Customization size and other requiremenst is available.
