tungsten carbide hardness 90.5 HRA with OD15 ID1.9 H13 mm
The compression ratio is large, and the working cone angle should take a larger value. As the carbon content in the steel increases, a smaller value should be taken, and the steel wire with higher quality requirements is drawn. To reduce the torsion cracking, the working cone is small. The length of the sizing belt is generally determined according to the properties, specifications, and lubrication conditions of the material being drawn. The low-carbon and high-carbon steel sizing belt is shorter, the larger diameter steel wire is smaller, the steel wire is smaller, and the wet drawing is shorter than the dry and wet drawing.
