Cemented carbide plate production process and processing precautions

Cemented carbide plate is also known as cemented carbide plate, cemented carbide plate material. It is one of the many materials of Cemented Carbide, which is named because of its rectangular shape of plate (or square). The main alloy components of Cemented Carbide Plate are WC and Co. The composition content of WC and Co in Cemented Carbide Plate for different applications is not consistent, and the scope of use is extremely wide. If you are interested in this, why don't you follow me to understand the relevant knowledge of Cemented Carbide Plate?

Introduction of Cemented Carbide Plate

Cemented Carbide Plate is one of the many materials of tungsten steel, which is made by powder making, ball milling, pressing and sintering using metallurgical methods. The composition content of WC and Co in tungsten steel plates for different purposes is not consistent, and the scope of use is extremely wide, with excellent hardness, high hardness, good wear resistance, high modulus of elasticity, high compressive strength, good chemical stability (acid, alkali, and other chemicals). Good stability (acid, alkali, high temperature oxidation), low impact toughness, low coefficient of expansion, thermal conductivity, electrical conductivity and iron and its alloys are similar to the characteristics. It is also an excellent material for making high-temperature-resistant parts, wear-resistant parts, anti-masking parts and corrosion-resistant parts. The use of tungsten steel plate should be specifically selected according to the use of appropriate materials.

Cemented carbide plate has excellent hardness, high hardness, good wear resistance, high modulus of elasticity, high compressive strength, good chemical stability (acid, alkali, high temperature oxidation), low impact toughness, low coefficient of expansion, thermal conductivity, electrical conductivity and iron and its alloys are similar to the characteristics of the tungsten steel cutter has a great deal of superiority, it is rapidly promoted in industry. In just fifty years, due to the use of tungsten steel turning tool, so that the metal cutting speed increased two hundred times, from ten meters per minute to more than two thousand meters. Heat-resistant tungsten steel still maintains good elasticity and mechanical strength, and is generally used for thicker cuts, interrupted cuts and poor part clamping. Coated tungsten steel is more effective and can be machined to HRC50° for all types of materials. It has 1~2 times longer service life and excellent impact resistance compared to general tungsten steel.

Tungsten steel plate use

Tungsten steel plate has excellent hardness, high hardness, good wear resistance, high modulus of elasticity, high compressive strength, good chemical stability (acid, alkali, high temperature oxidation), low impact toughness, low coefficient of expansion,

thermal conductivity, electrical conductivity and iron and its alloys are similar to the characteristics of the tungsten steel lathe, because tungsten steel lathe has a great deal of superiority, it is rapidly promoted in the industry. On the promotion. In just fifty years, due to the use of tungsten steel turning tool, so that the metal cutting speed increased two hundred times, from ten meters per minute increased to more than two thousand meters. Heat-resistant tungsten carbide remains flexible and mechanically strong, and is generally used for thicker cuts, interrupted cuts and poor part clamping. Coated tungsten steel is more effective and can be machined to HRC50° for all types of materials. Compared with general tungsten steel, it has 1~2 times longer service life and excellent impact resistance.

Application range of cemented carbide plates

The application of cemented carbide plates is mainly divided into three categories:

1. To be applied to make punching copper, aluminum, stainless steel, cold rolled plate, EI sheet, Q195, SPCC, silicon steel sheet, hardware, standard parts, upper and lower punches and other thin pieces of high-speed punching dies and multi-position progressive molds.

2. Used to make wear-resistant cutting tools. Such as woodworking industry with cutting tools, plastic crushing tools.

3. For the production of high temperature parts, wear-resistant parts, anti-mask parts. Such as guide rails for machine tools, anti-theft reinforcement plates for ATMs, and so on.

4. Used to make corrosion-resistant parts in the chemical industry.

5. Radiation and corrosion resistant materials for medical equipment.

6. The material properties of cemented carbide plates for different applications are not consistent, so the use of cemented carbide plates should be selected according to the specific use of the appropriate material.

Precautions for processing tungsten carbide plates

Tungsten carbide is brittle due to its high hardness, whether in use, handling, processing, prohibit knocking or throwing fall is prone to safety accidents, will cause personal injury and property damage, in order to avoid such unnecessary losses. We remind the majority of customers in the use of tungsten steel should be tungsten carbide processing precautions to pay close attention to the specific precautions are as follows:

First, in the cut-off, grinding processing:

1, tungsten steel in the impact and excessive processing loads are prone to cracking and chipping, tungsten carbide in the processing of the workpiece before the workpiece must be firmly fixed before processing.

2. Tungsten steel has very low magnetic properties and non-magnetic tungsten carbide has no magnetic properties at all. Do not use magnets to fix the tungsten carbide, use jigs and fixtures to fix it, and make sure that the workpiece is not loosened before machining, and if it is, fix the workpiece until it is firm.

3. The machining surface of tungsten steel is very smooth after cutting and grinding, and the corners are very sharp, so please pay attention to safety when handling and using.

4. Cemented carbide is a very hard and brittle material, afraid of impact, it is strictly prohibited to use metal hammers to hit the cemented carbide.

Second, in the discharge, wire cutting processing:

1, tungsten steel has a high hardness, high abrasion resistance, in the discharge, wire cutting operation process will be slower.

2. The surface of tungsten steel is most prone to cracking and chipping after EDM, so please adjust the processing program according to the usage conditions of the product.

3. Cracks often occur when cutting tungsten steel on the wire, so please make sure that the machined surface is free of defects after machining before proceeding to the next process.

3. For fusion welding process:

1. Please select the appropriate welding/fusion welding process according to the requirements.

2. Tungsten steel is prone to cracks during fusion bonding, so please make sure that there is no damage to the surface after processing before proceeding to the next process.

3, when the fusion welding operation generated by the scattered material (fusion iron) attached to the carbide, due to rapid heating and cooling will easily lead to cracking of the alloy, so when doing fusion welding operations, please be especially careful.

Fourth, in the HIT treatment:

1. When piercing and tapping on the filler (diffusion bonding), the filler may be shaken or part of the cemented carbide may be cracked, so please strengthen the inspection and make sure that there is no abnormality after the work.

2. In all processing operations: All safety devices on the machine must be used during processing operations. Staff must wear safety equipment that protects their eyes, hands, feet, head and all parts of the body.

Please reconfirm whether the workpiece is loose before processing, and if so, please fix the workpiece to a firm stop.

3. The surface of tungsten steel is very smooth after cutting and grinding, and the corners are very sharp, so please pay attention to safety when handling and using.

4. Cemented carbide is a very hard and brittle material, and is afraid of impacts, so it is forbidden to use metal hammers to hit cemented carbide.
