Heat treatment processing companies continue to develop
China's cheap labor and low-cost production will continue to attract foreign investment in the manufacturing industry, not only in the coastal areas, but also gradually expand to the mainland. In addition to the automotive industry, other manufacturing industries are mostly small and medium-sized enterprises. These companies will not be small and complete, but mainly rely on collaborative processing. This will encourage more heat-treated private enterprises to emerge in coastal and inland cities where small and medium-sized manufacturing companies are relatively concentrated. The current trend of foreign-funded enterprises investing in the construction of heat treatment plants has shown this. The large demand for light industrial molds, basic parts, and automotive and motorcycle accessories has also stimulated the development of the heat treatment processing industry. However, the heat processing capacity in China currently has a surplus phenomenon. The average utilization rate of equipment is only 30%. Many state-owned large-scale heat treatment departments implement single shifts and produce up to two shifts, or three days fishing and two days drying. After the heat treatment plants and workshops of these companies are transformed independently, the enthusiasm for external collaboration will greatly increase, causing an impact on the existing heat treatment market. Coupled with the further increase of private enterprises will form a fierce competition for customers and competitive pricing, resulting in adverse effects on product quality and corporate reputation. Therefore, Fan Dongli reminded that new heat treatment companies must be careful.
Enterprise technical transformation and equipment update requirements are strong
In the automobile, aerospace, weapons, molds and basic parts industry, driven by technological changes, the heat treatment technology and equipment renewal in other industries will follow. At present, the height and depth of technological transformation of enterprises have begun to show marked changes. Most enterprises are already not satisfied with the alternating old and new technologies and equipment, but tend to step by step to a higher level. Many private enterprises are even more focused on the effective deployment of funds, giving priority to the purchase of high-tech, high-quality, and high-reliability equipment. Even if they spend more, they will not hesitate to pay for high-level production goals.
The strong momentum of technological transformation of enterprises brings more opportunities for equipment manufacturing. In heat treatment furnaces, the need for conventional equipment such as box, well and salt bath furnaces will be further reduced. What is needed is more advanced technology, reliability and automation, energy saving and pollution-free equipment. This requires manufacturers to clearly and accurately grasp the development of new equipment at home and abroad and the market demand of users, put forward their own product development planning and measures to achieve the goal. The technological transformation of heat treatment companies has enabled more joint-stock companies and individual private enterprises to maintain a strong demand for advanced heat treatment equipment. Vehicles and fittings, basic parts and weapons industry will maintain strong demand for 600-1000kg furnaces for multi-furnace production. It is estimated that there will be at least 500 sets of multi-purpose furnaces, 200 sets of mesh belt furnaces, 50 sets of push rod furnaces and roller bar furnaces, and 20 sets of rotary hearth furnaces each year. The continuous technical upgrading of the light industry mold market and the aviation industry has enabled the vacuum heat treatment furnaces, especially the high pressure gas quenching furnaces, to require more than 300 units per year. In various atmosphere furnaces, the combustion furnace (light diesel oil and natural gas as fuel) will increase to more than 10% by 2010, and the use of natural gas to produce an endothermic atmosphere will increase to more than 20%. The demand for 80% vacuum heat treatment furnace by 2010 is a double chamber high pressure gas quenching furnace with a capacity of 1000 kPa (10 bar) or more. Low pressure carburizing and 2000Kpa (20bar) high pressure gas quenching lines will be promoted to some extent in the automotive industry. It is an important development trend to perform gas quenching instead of oil quenching in an inert gas of 1000-2000 kPa after carburizing with multiple furnaces.
Heat treatment process material market demand
Heat treatment process materials (quenches, seepage agents, anti-seepage agents, atmosphere and salt baths) and auxiliary materials (cleaners, rust inhibitors, desiccants, catalysts, etc.) are an important part of the heat treatment technology. Without quality process materials, the quality of heat-treated parts and various products cannot be guaranteed. The largest amount of quenching agent in the heat treatment process material. Although there are many claims that the polymer medium can completely replace the oil, in practice, due to certain characteristics and irreplaceability under certain conditions, it cannot be completely replaced for a long period of time. In the current heat treatment production, as a quenching medium, 50% of water and salt, alkaline aqueous solution, 40% of oil, 5% of nitrate bath, 3% of polymer solution, 1% of corundum powder and sulfur bed. It can be seen that the amount of quench oil still occupies a considerable proportion. Among the actually used quench oils, 90% are N22 and N32 mechanical lubricating oils, and the proportion of commercial quench oils is still less than 10% of the total. The annual demand for heat-treated quenching oil in the country is estimated at 30,000 tons, while that for commercial quenching oil is only about 3,000 tons.
Professor Fan Dongli also pointed out that although the market prospect of China's heat treatment industry is very promising, there are still many problems, such as unbalanced development of the company, low degree of specialization, large energy waste, most of the equipment is still old, and environmental protection and production safety awareness are weak. , The new equipment development capability is low, the quality of industrial and auxiliary materials is not high, and the quality of staff and workers needs to be improved. In short, the situation is promising, but the problem cannot be ignored. He hopes that the above issues should be resolved as soon as possible so as to constantly adapt to the needs of the greater development of the manufacturing industry and the national economy.
Domestic demand for heat-treatment-related equipment grows strongly
In the heat treatment industry where the manufacturing industry plays an important role, what are the current market demands and trends? At the managerial meeting of the national heat treatment industry manager recently held, Professor Fan Dongli, a senior metal heat treatment expert and former vice chairman of the China Heat Treatment Industry Association, told reporters that the current heat treatment industry in China is accompanied by the development of the manufacturing industry and the market demand is strong. Highlights in three areas:
