In the process of producing stainless steel chain, the enterprise did not carry out anti-rust treatment for the chain parts in the processing process and finished products after assembly in strict accordance with the requirements of cleaning and anti-rust regulations and oil seal anti-rust packaging. The quality of antirust lubricating oil, cleaning kerosene and other products used by enterprises in production cannot meet the requirements of technological regulations. As a result of stainless steel chain steel prices fell again and again, resulting in a gradual decline in the chain steel quality. For example, the content of nonmetallic impurities in steel is too high, the deviation of metallographic structure and so on. The chain steel source used by the production enterprise is more miscellaneous, the quality of steel is more yu long mixed beads. Some enterprises have poor environmental conditions, high content of harmful substances in the air, and small turnover site, which makes it difficult to carry out effective anti-rust treatment. With the arrival of the 21st century, all walks of life have been well developed. China's chain industry is full of vigor and vitality. Many new changes have taken place in production development, product structure, technical quality, market development and economic operation, and many new achievements have been made.
In the range of the development of the stainless steel chain, in addition to the chain of the product development and the emergence of new materials, enhance the function of stainless steel chain, improve the overall strength and stiffness, the emergence of programmable controller and computer, the development of stainless steel chain is a huge impetus, stainless steel chain of electrical control system with high precision, high sensitivity, high reliability of speed control, signal acquisition, signal transmission, logic execution components, make the electric control of the stainless steel chain level with rapid change, make some complex automated conveyor line with logical network function could be implemented.
Stainless steel chain: the parts are made of stainless steel. This kind of chain is suitable for use in food industry and other occasions which are vulnerable to chemical and pharmaceutical corrosion. It can also be used in high and low temperature occasions. The second is nickel plated chain, galvanized chain, chrome plated chain: all the carbon steel materials of the chain can be surface treatment, parts of the surface after nickel plated, galvanized or chrome plated treatment, can be used in outdoor rain erosion and other occasions, but can not prevent concentrated chemical liquid corrosion. Self-lubricating chain: some parts are made of a sintered metal filled with lubricating oil. This kind of chain is characterized by excellent wear resistance and corrosion resistance, no maintenance and long service life. Widely used in high stress, wear resistance requirements, and can not often maintenance occasions, such as food industry automation production line, high-grade bicycle racing, less maintenance of high-precision transmission machinery.
