Cemented carbide shell removal wheel
As the name suggests, the hard alloy shelling wheel is made of hard alloy. Its main function is to remove rust from wire rod. The hard alloy shelling wheel has good product quality, wear resistance, high temperature resistance, high hardness and long service life.
The iron oxide scale on the surface of the wire rod is relatively brittle and has little extensibility. The steel wire can be locally stretched and extruded by bending, which can effectively remove a large amount of iron oxide. For different materials, the elongation of steel wire can be simply tested through tests, and finally the size of the shelling wheel can be determined. The samples were placed in the tensile testing machine. With the increase of tensile strength, the samples expanded, and the scale on the surface of the samples began to fall off. The results showed that the elongation was about 8%. Most of the iron sheets fall off, and only a part of the iron oxide powder remains on the surface of the iron wire. This part of the powder can be removed by scrubbing. In practice, the elongation can not reach 8%, because too high elongation will seriously damage the wire surface and affect the wire quality. The stripping rate of iron oxide scale is related not only to the diameter of carbide shelling wheel, but also to the angle of steel wire edging. The greater the ladle angle, the greater the bending deformation of the wire rod when passing through the shelling wheel, and the iron oxide skin stripping rate will naturally increase. However, too large wrap angle not only makes the shelling wheel wear faster, but also increases the traction required, and also causes damage to the steel wire surface.
The quality of carbide shelling wheel is also one of the factors that affect the stripping rate. An excellent carbide shelling wheel can not only ensure a good stripping rate, but also reduce the traction force.
