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 the steel wire drawing on the surface under the dry friction state of water shortage and lubrication, and the steel wire brings a lot of drawing heat. Therefore, the drum is a vulnerable part bearing high temperature and high wear.
The surface wear of drum directly affects the quality of steel wire. The excessive wear leads to the increase of production cost and the decrease of production efficiency. According to the matrix material, drum can be divided into cast iron, cast steel, low carbon steel, high carbon forged steel, carbon steel and so on. Different substrate materials, using their own surface treatment, will appear different wear patterns.
The wear resistance of the drum depends on the hardness of the surface coating as well as the strength and hardness of the matrix. For the above five kinds, the cast iron drum with poor shear strength, wear resistance material and adhesive wear ability are all poor. Low carbon steel drum with soft matrix material has poor plastic deformation resistance. And the strength and hardness are relatively high medium and high carbon steel drum wear resistance is obviously better, especially after the surface hardening and surface coating treatment of medium carbon steel drum wear resistance is better, the drum is in a low wear state for a long time.
Using supersonic flame spraying technology to spray carbide coating on the surface of drawing reel, drawing machine, drawing wheel, wire wheel, wire drawing cylinder, wire reel, guide groove and other parts, the surface hardness can reach about HRC68, far higher than the wear resistance of abrasive steel or chilled cast iron; Also can make the matrix of these parts made of ordinary steel or cast iron, not only reduce the cost, but also prolong the service life.
