Sand Belt Polishing Machine

Sand Belt Polishing Machine

The sand belt polishing machine replaces pickling with an environmentally friendly and non-emission method and removes more than 98% of the oxide layer on the surface of the wire (raw material).

The sand belt polishing machine manufactured by YF Metal Tech uses a 7.5KW motor to rotate the turntable around the steel wire 360° to ensure that the steel wire is in contact with the abrasive belt without omission.

The sand belt is driven by a 7.5KW motor to move two rollers equipped with sand belts to press the surface of the wire tightly to move so that the surface of the wire is slightly cut. Generally, the surface of the wire will be evenly cut off by 0.03mm.

However, during work, the oxide skin is constantly stuffed between the sand grains on the surface of the sand belt, which makes the sand belt slowly fail, usually not more than 24 hours.

In order to improve the service life of the abrasive belt, the steel brush sheller is placed in front of the sand belt machine, which not only ensures that the steel wire is 100% removed from the oxide layer but also increases the service life of the abrasive belt by 5 times.

The company recommends that the sand grain size of the abrasive belt be selected between 40 mesh and 600 mesh. The larger the mesh number, the smoother the surface of the steel wire. The 600 mesh sand grain can make the surface of the steel wire as smooth as a mirror. The steel wire can be directly plated with bright chrome or galvanized.

The sand belt polishing machine produced by YF Metal Tech has a simple structure. It only takes 1 minute to replace two abrasive belts. The sand belt-positioning system is simple and flexible. The debugging time is only 10 minutes. The abrasive belt will never move or slide during use.

YF Metal Tech’s sand belt polishing machine can increase the speed of low-carbon steel wire drawing and produce ordinary black iron wire.

Use a belt machine between the wire drawing machine and the shelling machine. Use a 60-mesh sandbelt to form spiral stripes on the surface of the steel wire. The depth of the stripes is about 0.025mm. These nebulous stripes can make the steel wire carry more lubrication when it enters the mold. Powder, so the drawing speed is generally increased by 50%.

If the mold adopts nano-coating, the outlet speed of 2mm steel wire should reach at least 20m/s, and the outlet speed of 1mm steel wire should reach at least 30m/s. And the service life of the mold is usually 500 tons.

The sand belt polishing machine produced by YF Metal Tech is used to produce welding wire. The use of coating molds saves boron coating and drying and reduces the cost of welding wire by 100 RMB per ton.

The sand belt polishing machine produced by YF Metal Tech is used to produce stainless steel wire, which can avoid coating agents and drying, does not accept weather interference, and saves more than 50 RMB in cost.

The sand belt polishing machine produced by YF Metal Tech is used to produce high-carbon steel wire without pickling, which meets the requirements of environmental protection.

Sand belt polishing machine is only limited to rust removal on the surface of steel wire with a diameter of 4mm or more.

The steel wire de-rusting machine can derust the steel wire below 4mm.

The principle is that the steel wire passes through the center of the steel brush, and the steel brush rotates around the steel wire at a speed of 1500 rpm, so as to realize rust removal on the surface of the steel wire.

This machine has the best effect on the rust removal of the steel wire after annealing, because the rust after annealing is very loose, and the raw materials are difficult to handle because they are exposed to air and rust, and must be removed with a belt polishing machine.

No matter what kind of machine, the steel wire must be straightened before rust removal!

The principle of the steel wire straightening machine for straightening steel wires above 4mm is to bend the steel wire repeatedly to loosen the scale on the surface of the steel wire, and at the same time, the huge bending force straightens the steel wire! The bending wheel material is tungsten steel YG8.

For steel wires, less than 4mm, especially annealed steel wires, use a bending and straightening wire machine! Bending wheel material bearing steel GCr15.
