Specialized production of heat treatment flourishes Since the implementation of the market economy in the country, since 1995, the development of specialized production of heat treatment has been rapid, mainly in the rapid growth of private-owned, joint-stock franchise heat treatment processing enterprises. In 2003, the total number of such enterprises mainly concentrated in coastal cities was at least 2,000. In recent years, private heat treatment enterprises in North China, Northeast China and the Mainland have also seen a significant growth trend. The national heat treatment professional factory is likely to reach 3,000. The average annual turnover of each enterprise is 2 million yuan. The annual turnover of such enterprises in the country can reach 6 billion yuan, accounting for about 20% of the total turnover of national heat treatment. This ratio is greater than 10% in the US and less than 30% in Japan. It is undeniable that this is the greatest achievement in the past few years since the country promoted specialized production in the 1980s, and it is also the inevitable outcome of deepening reform and promoting the socialist market economy. Heat treatment production technology transformation and equipment renewal Most private companies recognize the importance of a high-tech starting point to maintain a strong competitive edge. They have sufficient funds and ability to purchase advanced heat treatment equipment. Aviation, weapons and shipbuilding enterprises have benefited from the national defense modernization policy in recent years, and have carried out large-scale technological transformation and equipment renewal. The unprecedented development of the automotive industry has created a large demand for advanced heat treatment technology and high-precision heat treatment equipment. Aviation industry enterprises and coastal private enterprises with light industrial products and molds as the main target have added a large number of vacuum heat treatment equipment in recent years, especially high-pressure gas quenching equipment. . Automobiles, weapons industry enterprises and private enterprises with automobile and motorcycle parts as the main targets use the multi-purpose furnace production line as the main technical transformation content. The heat treatment department of individual automobile companies also introduced a low-pressure carburizing and high-pressure gas quenching heat treatment production line. Shipbuilding enterprises are aiming at the technical transformation of large-scale well carburizing furnaces with precise control of the carbon potential of the blast furnace temperature uniformity. Among these enterprises, due to the vigorous development of production technology, the proportion of less oxidation heat treatment has reached more than 90%. Basically, advanced heat treatment production with less oxidation, less distortion, less pollution, less waste, less labor, and no mass dispersion is realized.
