Characteristics and advantages of HV-80-JP supersonic flame spraying system

1, Solid cabinet design, fuel flow control area, pressure display area, electronic control area are modular layout, panel clear and easy to operate.
2. All imported valves, pressure switches, flow switches and sensors from Europe and America are of the same quality as those from Europe and America
3, The use of Japanese mitsubishi high-performance PLC control, after ignition automatically maintain oxygen and fuel, carrier gas flow output.
4. All the internal fuel, oxygen, carrier gas and cooling water connected on the equipment have the detection function to ensure that all preparation processes can be fully tested before ignition.
5. Monitor the running status of the equipment in real time. Once any part is found to be operating beyond the safe range, the whole system will stop sharply, send an alarm and provide fault information.
6. The equipment starts and stops automatically under the control of PLC, which reduces the possibility of operator's misoperation.
7. Communication interface is set up inside the equipment to control the operation of peripheral devices.
8. Signal shielding measures are adopted to protect peripheral devices from electromagnetic interference during high frequency arc ignition.
 

System on line equipment drawing reel and cone pulley surface need to be the excellent properties of wear resistance and fatigue resistance, otherwise the service life is short, often need to change, greatly increased the production cost of the customer, reel in drawing process improve the drawing force, the transfer between the drum and wire is relying on the outside of the drum and the friction between wire, drum under friction wear. When the surface of the drum is in contact with the steel wire, it bears the high pressure of steel wire drawing on the surface under the dry friction state of lack of water and lubrication, and the large amount of drawing heat brought by the steel wire. Therefore, the drum is a vulnerable part that bears high temperature and high wear.
The surface wear of the drum directly affects the quality of steel wire. Rapid wear leads to the increase of production cost and the decrease of production efficiency. According to the base material, the drum can be divided into cast iron, cast steel, low carbon steel, high carbon forged steel, medium carbon steel and so on. Different wear patterns will appear when different substrate materials are treated with different surface treatments.
The wear resistance of the drum depends on the hardness of the surface coating and also on the strength and hardness of the substrate. The above 5 kinds of cast iron reels with poor matrix shear strength, wear resistance and adhesive wear resistance are all poor. Low carbon steel rolls with soft base material have poor resistance to plastic deformation. The wear resistance of the medium and high carbon steel drum with high strength and hardness is obviously better, especially after the secondary surface hardening and surface coating treatment of the medium and high carbon steel drum is better, and the drum is in a low wear state for a long time.
The supersonic flame spraying process is used to spray carbide coating on the surface of drawing drum, drawing machine, drawing wheel, wire wheel, drawing cylinder, drawing reel, guide groove and other parts. The surface hardness can reach HRC68, which is far higher than the wear resistance of abrasive steel or cold cast iron. The base of these parts can also be made of ordinary steel or cast iron, which not only reduces the cost, but also prolongs the service life.
