Ra6.3 Ra12.5 Wire Rod Shot Blasting Machine PLC Control 20r/Min

Wire rod shot blasting machine

The purpose of this machine is to clean coiled wire rods by using the shot blasting process. It effectively removes oxide scale and surface scale layers formed during steel rolling. The shot blasting process achieves a surface derusting grade of Sa2.5 and a surface roughness grade of Ra6.3-12.5μm on the round billet.

Compared to traditional pickling treatment methods, this machine offers several advantages. Firstly, it is more economical and cost-effective. Secondly, it is environmentally friendly, as it does not involve the use of chemicals or generate harmful waste. Lastly, it is highly efficient, with an output capacity of 15-20 t

ons per hour.

The machine features a unique design with a "rotating gate + double cantilever shaft" carrying plate for the round wire material. This design enables a double-station working mode, significantly enhancing the equipment's production capacity. The cantilever shaft, made of special alloy steel, allows the wire to undergo a compound action during the shot blasting process, including "up and down + left and right swing + positive and negative rotation." This compound action ensures thorough cleaning of the wire.

The shot blasting devices are strategically arranged to ensure effective impact on both the inner and outer surfaces of the coiled wire. The entire machine is intelligently controlled by a programmable logic controller (PLC), offering convenient and reliable operation.

The purpose of the machine
This machine uses four beams of projectiles thrown by a shot blasting machine manufactured by foreign advanced technology to hit the fast-moving wire surface to remove the rust layer and oxide scale on it to obtain a clean metal surface. It is used in the metal product manufacturing industry. The machine benefits are as follows:
1. Remove the rust and oxide layer on the wire surface.
2. The surface layer of the wire rod after shot blasting shows uniform roughness, which is beneficial to increase the adhesion of aluminum and copper packages, and the cladding is uniform and never falls off.
3. Eliminate the internal stress generated during the wire drawing process of the bar.
4. Increase the tensile strength and stress corrosion cracking resistance of the wire surface to obtain a permanent service life. This machine is the best suitable model for the treatment of wire surface oxide scale in the manufacturing industry.
Features of the machine
1. The equipment has high efficiency, and the cleaned wire surface is clean and metallic.
2. The shot blasting machine adopts special shaped blades to focus on the shot, with high density of shots, which improves productivity.
3. The spacing between the wires by the guide can control the swing of the cleaned wires to achieve the purpose of cleaning.
4. A number of domestic and foreign advanced technologies are used to improve the technical content of functional components, so that the machine has a low failure rate and a high start-up rate. The sealing effect is good, and it reaches the environmental purification index required by environmental protection.

working principle
The front power (provided by the user) on the wire to be cleaned passes through the shot blasting chamber through the pressure wheel, and the high-speed shots are shot by two upper and lower shot blasting machines arranged inside the shot blasting chamber, and two left and right shot blasting machines arranged on both sides. Strike the surface of the passing wire to remove the oxide scale and rust layer on its peripheral surface. After cleaning, the pellets are sent to the lower part of the elevator by the screw conveyor, and the pellets are sent into the separator by the elevator, and the qualified pellets are fed into the hopper through the airflow for recycling. The unseparated mixture of pellets is returned to the shot blasting The chamber continues to circulate. After the fine rust and dust are purified by the sedimentation cylinder and the dust collector, the large particles are captured and collected, and the pure gas is discharged into the atmosphere.
