Matters needing attention in the production of cemented carbide strips

Cemented carbide strip is a hard material made of tungsten, cobalt, carbon, titanium and other powders sintered at high temperature. It can be used to make many machining tools such as cutter head, turning tool, insert plate, machine tool, grinding wheel, boring tool, etc., because it has high hardness, strength and wear resistance, and can withstand high temperature, high pressure and chemical corrosion.
Carbide strips are widely used in machining, automotive tools, oil drilling, aerospace, electronic equipment, metallurgical industry, iron and steel smelting, chemical industry, medical equipment and other fields. Among them, mechanical processing is representative, and its application scope includes machine tools such as drills, milling cutters, fitter fixtures, grinding tools such as grinding wheels, and parts processing.
The following aspects should be paid attention to in the production of cemented carbide strips:
Powder batching: The raw materials for the production of cemented carbide strips are mainly powders of tungsten, cobalt, carbon, titanium and other substances, so these powders need to be batched before production to ensure the uniformity and stability of the material.
Sintering process: The sintering process of cemented carbide strips is one of the key factors determining its quality and performance. The process needs to be carried out at the right pressure and temperature to ensure that the powder sinters into a hard material, as well as the right protective gas to avoid oxidation.
Polishing and processing: Carbide strips need to be polished and processed after production. These processes require professional equipment and technology to ensure the smoothness and dimensional accuracy of the strips for better application in machining and other industrial fields.
To sum up, tungsten carbide strip is an important machining tool and an indispensable material in many industrial fields. During its production and application, it is necessary to pay attention to the ingredients of materials, sintering process, polishing and processing to ensure that its quality and performance meet the requirements.
1. The strength and hardness of cemented carbide strips are very high
Carbide strips have very high hardness, and its hardness is about 60 HRC, which is difficult for ordinary metal materials. When the hardness exceeds 60 HRC, its wear resistance and toughness will decrease with temperature, and when the hardness exceeds 75 HRC, its strength, wear resistance and toughness will increase with temperature.
The strength and hardness of carbide strips is as high as 500 HRC, which even exceeds the hardness of diamond material. This is because the tungsten steel strip in the cemented carbide mold adopts special powder metallurgy technology and is produced through advanced sintering technology.
2. Carbide strips have good chemical stability
Cemented carbide strips will not suffer from oxidation, carbonization and other problems under high temperature and high pressure.
