Tungsten carbide Wear-resistant Strips are Available to Enhance Vegetable Oil Production Efficiency

Vegetable oil is the most important food for the people. It is not only the most basic raw material for the food industry, but also an important raw material for industrial and agricultural production and national defense construction. The most critical equipment for the production of vegetable oil is the oil press, and the squeeze bar is one of the main working parts of the oil press. In addition to supporting the pressed material, it also clamps and squeezes the material together with the pressed screw. Due to the friction and extrusion of oil crops, the wear of the strip is very serious. Therefore, improving the service life of the strip has become an urgent problem for the manufacturers of vegetable oil plants and oil presses.

At present, the wear-resistant treatment process of the pressed strip is mainly based on carburizing treatment, which not only has a long production cycle, large power consumption, high cost, large deformation, and low hardness, which is the main reason for its resistance to wear. Although the production cost of the carburizing strip is low, the service life is short, generally about 10 days, and the frequent replacement of the strip not only causes the shutdown to stop production, but also increases the production cost of the oil plant. A new type of tungsten carbide wear-resistant strip has emerged for the problem of short cycle time of carburizing.

Tungsten carbide (WC) material has excellent comprehensive properties such as high hardness, high wear resistance, high chemical stability and high temperature resistance. It is the most widely used and most applicable machining tool material in the field of application, and is widely used in vehicles. Planing, milling, reaming, boring, drilling, grinding and other tools. In the industry, tungsten carbide is an ideal coating material with high temperature resistance and wear resistance. Spraying wear-resistant tungsten carbide coating on the device can greatly improve its performance and service life.

Recently, a new type of tungsten carbide wear-resistant strip has been introduced, which can greatly improve the working efficiency of the oil press, reduce the downtime and repair time and the frequency of press strip replacement, and reduce the labor intensity of workers, bringing extremely obvious economic benefits to oil companies.

The pressed bar is an irreparable product. The scientific research personnel comprehensively consider the factors such as performance, cost and technical maturity. The tungsten carbide material is selected and the surface-hardened wear-resistant layer is prepared by using advanced technology to make the surface of the strengthened tungsten carbide wear-resistant pressed bar even and even. Beautiful, low roughness, no obvious visible processing defects, and no deformation, no need to meet the assembly requirements in practical applications, can ensure the uniformity and stability of engineering processing quality. In addition, the service life of tungsten carbide is 7 times that of single-sided carburizing, without stopping the machine, no change, it can be used for 4-5 months.

The successful research and popularization and application of tungsten carbide wear-resistant strip can not only bring convenience and economic benefits to oil plant users, but also improve the technical level and market competitiveness of domestic oil presses and promote the scientific and technological progress of the grain machine manufacturing industry.
