In the selection of the National Science and Technology Progress Awards that ended not long ago, the project “Development and Industrialization of High-grade Series of Internal Combustion Engine Oil Compounds†declared by CNPC Lubricant Company won the second prize. This is the third time the company has won a national science and technology award in four years. The general manager of the company, Dr. Liao Guoqin, frankly stated that since the company was founded, it has experienced very difficult efficiency pressures, and there have been serious differences and disputes over the investment and value of scientific research. However, it has always insisted that R&D is the core competitiveness of the lubricant industry. The continuous increase in R&D investment has always promoted the transformation from results to market. According to her, 12 years after its establishment, the company has invested more than 900 million yuan in scientific research. The company's award-winning items have been widely acclaimed by the industry. Its award-winning projects have reached the international advanced level, or achieved a higher share of the high-end oil products market, or brought huge benefits to the company. At the same time, it has made the market power and reputation of the “ Kunlun †brand as an independent lubricant oil brand. More and more high.
Wear-resisting Steel Plate is composed of low Carbon Steel Plate and alloy wear-resisting layer. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity of resisting external forces, and the alloy wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.
Wear-resisting steel alloy wear-resisting layer and base plate are metallurgical combination. By means of special equipment and automatic welding process, the high-hardness self-protecting alloy wire is uniformly welded on the substrate, and the composite layers are one to two or even more. In the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear, which is a significant feature of the wear-resistant steel plate.
The wear resistant layer of the alloy is mainly chromium alloy, while manganese, molybdenum, niobium, nickel and other alloys are added. The microhardness of carbide can reach above hv1700-2000, and the surface hardness can reach hrc58-62. Carbide alloy has a strong stability at high temperature, maintain a high hardness, but also has a good oxidation resistance, within 500℃ completely normal use.
The wear-resistant layer has narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (S, W), etc. It is mainly composed of chromium alloy, while manganese, molybdenum, niobium, nickel, boron and other alloy components are added. With 40-60% carbide content, the microhardness can reach above HV1700 and the surface hardness can reach hrc58-62.
