In the manufacturing sector plays an important role in the heat treatment industry, the current market demand and the trend of how? At the recent meeting of the China heat treatment industry manager meeting, China's senior experts, the original Chinese heat treatment of metal heat treatment industry association and vice chairman of Professor Fan Dongli said that China's current development of heat treatment industry with manufacturing industry, strong market demand, is prominent in three aspects:

Continuous development of heat treatment processing enterprises

China's cheap labor and low-cost production will continue to attract foreign investment in manufacturing, not only in the coastal, but also gradually extended to the mainland. In addition to the automobile industry, other manufacturing industries are small and medium enterprises. These enterprises will not engage in small and full, but mainly rely on collaborative processing. This will encourage more heat treatment of private enterprises in small and medium manufacturing enterprises are relatively concentrated in coastal and inland cities emerging. At present, the momentum of the investment in the construction of the heat treatment process has been the trend of the foreign investment enterprises. A large number of light industrial molds, basic parts, automobile and motorcycle parts demand has stimulated the development of heat treatment processing industry. However, the processing capacity of heat treatment in China at present the phenomenon of excess equipment, the average utilization rate of only 30%, the heat treatment department in many large state-owned companies to implement a single class, most classes of production, or three days of fishing, two days. The enthusiasm of foreign cooperation will be greatly increased, resulting in the impact of the existing heat treatment market. With the further increase in private enterprises will form the intense competition for customers and compete to lower prices of the situation, have a negative impact on product quality and enterprise reputation. Therefore, Fan Dongli reminder, new heat treatment enterprise, we must be careful.
Enterprise technical innovation and equipment update requires strong

In the automotive, aerospace, weapons, tooling and technical transformation of the base of the industry under the pull of the other industries to heat treatment technology and equipment update will follow the climax. At present, the technical transformation of enterprises height and depth have been significant changes, turn most enterprises are not satisfied with the conventional technology and equipment, but tend to step a step towards a higher level. Effective delivery of many private enterprises more focused on capital, preferred to buy advanced technology, high quality and high reliability of the equipment, to achieve a high level of production targets, even if the money expense.

Strong technological transformation of enterprises to bring more opportunities to the equipment manufacturing industry. In the heat treatment furnace, box type, well type and salt bath furnace and conventional equipment demand will be further reduced. Need more advanced technology, high reliability and automation, energy saving and pollution free equipment. This requires manufacturers to clearly and accurately grasp the development trend of new equipment at home and abroad and the user's market demand, put forward their own product development planning and implementation of the objectives of the measures. Technological transformation of heat treatment enterprises, so that more joint stock enterprises and individual private enterprises to the demand for advanced heat treatment equipment is still maintained a great momentum. Vehicles and parts, the basic parts and weapons industry will be installed on the 600~1000kg furnace production line to maintain strong demand. It is estimated that there are at least 500 sets of multi furnace, 200 sets of net belt furnace, 50 sets of push rod furnace and rotary hearth furnace, 20 sets of rotary hearth furnace. The strong market and the continuous technological transformation of the aviation industry to make the vacuum heat treatment furnace, especially the high pressure gas quenching furnace, need more than 300 units per year. In all kinds of atmosphere furnace combustion furnace (with light diesel and natural gas as fuel) to 2010 will increase to more than 10% of the proportion, with natural gas to prepare endothermic atmosphere will increase to more than 20% of the proportion. By 2010 80% vacuum heat treatment furnace demand is 1000kPa (10bar) above the double chamber high-pressure gas quenching furnace. Low pressure carburizing and 2000Kpa (20bar) high-pressure gas quenching production line will be a certain degree of promotion in the automotive industry. The development trend of gas quenching in 1000~2000Kpa inert gas is an important trend in the process of gas carburizing.

Heat treatment process materials market demand

The heat treatment process of material (quenching agent, penetrating agent, waterproof agent, atmosphere and salt) and auxiliary materials (cleaning agent, anti rust agent, desiccant and catalyst) is an important part of heat treatment technology. Lack of quality process materials, can not guarantee the quality of heat treatment parts and all kinds of products. Quenching agent is the most used in heat treatment process. Although there are a lot of polymer media can completely replace the oil argument, but in fact, due to some unique characteristics and the specific conditions of irreplaceable, in quite a long period of time can't be completely replaced. In the heat treatment of the current production, as the quenching medium, 50% water and salt and alkali solution, 40% oil, 5% with nitrate salt bath, 3% with polymer solution, 1% with corundum sulfur powder bed etc.. Thus, the amount of quenching oil still accounts for a large proportion of. In the actual use of the quenching oil, 90% is to use N22, N32 mechanical lubricating oil, the use of the proportion of commercial quenching oil is still less than 10% of the total. The heat treatment of quenching oil demand is estimated to be 30 thousand tons of goods, and only about 3000 tons of quenching oil.

Professor Fan Dongli also pointed out that the heat treatment industry in China despite the market prospect is very promising, but there are still a lot of problems, such as enterprise development is not balanced, the degree of specialization is not high, the energy waste is high, most of the equipment is still obsolete, environmental protection and safety awareness is weak, the development of new equipment of low capacity, high quality workers and auxiliary materials the staff, to improve the service quality etc.. In short, the situation is optimistic, but the problem can not be ignored. He hoped that the above issues should be resolved as soon as possible, in order to continue to adapt to the manufacturing and the national economy more hair
