Component	Characteristic	Parameter
E-2000 Powder feeder	1. The powder feeder is a high-precision powder feeding mechanism based on the principle of toothed dial with vibration structure and gravity falling, with uniform powder output and wide particle size range. 2. After the top cover is sealed, the powder condition in the powder cylinder can be clearly seen through the visual transparent observation window on the powder cylinder. 3. Nitrogen or argon with small flow is used as powder gas. The powder is rotated to the powder outlet along with the powder tray at the bottom and enters into the spray gun together with the powder gas. 4. Adopting the latest international turnover structure, it is convenient to clean the powder, which can be discharged from the lower mouth, or can be poured from the barrel body.	1.

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.

Our company in the cathode material and battery production equipment iron ion isolation and wear reduction of impurities into the accumulation of perfect solutions, and the cathode material processing into finished battery greatly improved its self-discharge performance.

Battery material production process, there shall be no contact with the iron component, a lot of conical cylinder and conical spiral mixer, two of the mixing screw is made of stainless steel body, but the powder in the process of mixing with batteries, constantly friction cylinder, working long hours, barrel and screw blade will appear a lot of wear and wear down the stainless steel impurities mixed in battery powder, Iron content in stainless steel is up to 70%, which causes serious pollution to battery powder. In the past, coating was generally used for equipment, which needed regular maintenance due to its short life and poor high temperature resistance. However, our company used wear-resistant tungsten carbide coating to solve such problems.

Our company adopts integral tungsten carbide spray treatment for the contact parts of high speed mixer, complete machine, accessories (blade, tank, discharge port) and materials in the cathode material production equipment.
For the double cone screw mixer (screw, tank) overall spraying treatment to solve the previous FRP coating into the cathode material of sodium borosilicate and other element impurities.
After the treatment of the stirring paddle of the battery mixing equipment, the impurity introduction of the stainless steel wear agent was reduced, and the self-discharge ratio of the battery was greatly reduced.
