With the rapid development of China's national economy and the deepening of reform and opening up, China's stainless steel chain industry is full of vitality, in the production development, market development, product structure, technical quality, economic operation and other aspects of many new changes, has made a lot of new results. Look at the current total industrial production of stainless steel chain, our country has entered the world in production of stainless steel chain, but looked from the overall strength and development level, stainless steel chain per capita annual output is only about 1/5 of the international developed countries, most of the motorcycle stainless steel chain in the world is not beyond the C level, the chain of international market share is only 4.5%, so our country is still far from into chain world powers.
In the development of stainless steel chain also encountered a variety of problems, such as quality problems, or raw materials, so the development of the chain is blocked, and our company's products used materials are experience of various departments to check, for the stainless steel chain product processing automation to provide an effective guarantee. Secondly, we have invested more technology and made great progress in quality and performance, making our products more competitive than those of other enterprises. We will strive to further improve and perfect the chain and other products so as to meet the different needs of the vast number of users. There are also some phenomena such as violating rustproof regulations.
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.
Part material is stainless steel, this kind of stainless steel chain is suitable in food industry and is easy to be corroded by chemical, medicine and so on occasions use, also can 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.
