Now people's understanding of the importance of this issue is far the level of understanding of the environment. At present, national leaders many people of insight fully realize that the solution to this problem cannot be achieved by preaching alone. It is time to legislate formulate laws regulations. The potential of effective utilization, economical use reuse of fuel, power, water, oil other resources for heat treatment equipment is huge. The energy source of multi-purpose furnace heat treatment heating equipment must be selected reasonably according to the local conditions. The heat efficiency of the heating equipment has great room for improvement. The waste heat of fuel products must be fully utilized. A large number of cooling water must be recycled. The grease cleaned the surface of the workpiece shall be recycled by classification. The invalid quenching oil shall be collected, refined reused used for other purposes. In a word, the effective utilization regeneration of resources is an important part of the sustainable development strategy of heat treatment industry.

China is a big energy consumer, machinery manufacturing industry is a very important part of it. With the continuous development of heavy industries such as parts components, machinery manufacturing so on, heat treatment plays an important supporting role in the revitalization development of China's machinery manufacturing industry, the development of machinery manufacturing industry will certainly drive the rapid development of China's heat treatment industry, provide a broad development space for the development of China's heat treatment industry, the industry has a broad development prospect. The 12th Five year plan specifically points out that it is necessary to make full use of the industry information platform, promote new technology, guide enterprise innovation, vigorously develop energy-saving heat treatment; give full play to the advantages of technology research development service platform to provide support for energy conservation emission reduction in the industry; give full play to the role of the expert committee as a think tank, earnestly organize recommend basic engineering projects.

The waste water, waste gas, waste salt, dust, noise electromagnetic radiation produced by the multi-purpose furnace heat treatment will pollute the environment. To solve the environmental pollution of heat treatment to implement clean heat treatment ( green heat treatment) is one of the development directions of heat treatment technology in developed countries. In order to reduce the emission of SO2, Co, CO2, dust cinder, the use of coal as fuel has been basically eliminated, the use of heavy oil is becoming less less. The majority of light oil is used, natural gas is still the ideal fuel. The waste heat utilization of combustion furnace has reached a high level. The optimization of burner structure strict control of air-fuel ratio ensure the reasonable combustion reduce NOx CO to a low level. Gas carburizing, carbonitriding vacuum heat treatment technology are used instead of salt bath treatment to reduce the pollution of waste salt water source containing CN toxic substances. Water soluble synthetic quenching oil is used instead of partial quenching In order to reduce oil pollution, biodegradable vegetable oil is used instead of some mineral oil.

Induction heat treatment equipment has many advantages, such as fast heating speed, energy saving, no oxidation decarbonization, no pollution to the environment high production efficiency, which are widely recognized by heat treatment workers, so it has developed rapidly in the past decade. Of course, this actual demand also greatly promotes the development technical upgrading of domestic induction heat treatment equipment. Taking FAW in Changchun as an example, the company has more than 100 induction heat treatment equipment, of which 50 have been newly added updated in the past decade, almost all of which are SCR if equipment IGBT super audio equipment. At present, the weight of induction heat treatment parts of FAW's medium-sized trucks has reached 291.3kg, accounting for 52% of all heat treatment parts. Induction heat treatment has really raised half of the heat treatment.

The above is a multi-purpose furnace manufacturers to introduce the relevant content, I hope to help you.
