Carbide rollers ,also known as tungsten carbide rolls, tungsten carbide rolling rings, are widely used in steel forming, especially in cold rolling mills.
Carbide rings are worked as groups of 3 pieces, we also call it 3D carbide rolls.
Rolls can be separated according to their working positions: RO,RT,FO,PR or CA type.
During the cold heading process of standard parts, the cemented carbide cold heading die has to withstand large impact forces. In order to meet the usage requirements, it is necessary to choose cemented carbide with high cobalt content, high strength and good impact toughness.
Tungsten carbide cold heading molds are used for fastener screws, bolts and rivets. Carbide molds have high hardness and can withstand high pressure and stress.
1. Cold heading is carried out under normal temperature conditions. Cold heading can improve the mechanical properties of metal parts.
2. Cold heading forging process can improve material yield. It is a pressure processing method based on plastic deformation, which can achieve less or no cutting processing. Generally, the material utilization rate is above 85%, and can reach as high as above 99%.
3. Can improve production efficiency. The time and process of deforming metal products are relatively short, especially when parts are processed on multi-station forming machines...
4. The cold heading and forging process can improve the surface roughness of the product and ensure product accuracy.
The main brands of Cemented Carbide Wire Drawing Dies are YG8, YG6, and YG3, such as the new brand YL used for high-speed wire drawing, and the wire drawing die brands BK20 K20 K30 introduced from abroad, which can be widely used in metal drawing processing.
YG20C YG25C is high cobalt content, coarse particle size, high impact toughness, suitable for processing large flange screw molds above M20, impact-resistant Tungsten Carbide Cold Heading Dies
Ordinary Tungsten-cobalt Cemented Carbide has a density of 12.9~13.2g/cm³, a Hardness of 82~85HRA, a tensile strength of 2700~3300MPa, a bending strength of σbb=1800~2700MPa, σbc=3200MPa, and an impact toughness value of 5.5J/c ㎡.

High Hardness Tungsten carbide Hot forging die for hexagonal nuts
are widely used in hex steel nut production.
we recommend HRS6 HRS7 Grade
Hardness 83.5-84.5HRA ,with good toughness and wear resistance,HRS6 is a good choice for
drywall screws, self-taping screw and hex head screws below M16
Used in reduction mold, Hex group forming mold, nut mold and lasering punches.
For key equipment such as rolls, the technical requirements are very high. It requires the selection of appropriate materials, hardness, contours, etc., and detailed and scientific design and manufacturing based on actual production conditions to ensure that the equipment can operate stably and efficiently and ensure product quality. and business benefits.
