Advantages of industrial electric furnaces

With the development of emerging science and technology, various high-performance requirements have been put forward for materials, so that they can be applied to cutting-edge technologies such as computers, communications, lasers, aviation, aerospace, nuclear energy and national defense science; new materials have superior properties such as high temperature resistance, wear resistance, corrosion resistance and high strength, and have shown broad development prospects.

The research and production of these materials and performance testing need to be carried out at high temperatures, and the temperature, pressure, atmosphere, temperature field and other process conditions are very strict. The design and development of new high-efficiency thermal equipment and the research on high-temperature generation technology largely determine the further development of materials. The design, construction and commissioning of heat sources used to manufacture high-temperature materials require the same amount of labor and cost as the research and development of new materials. For many materials and products, in addition to atmospheric pressure and vacuum sintering, the application and continuous progress of hot pressing sintering, atmosphere pressure sintering and hot isostatic pressing technology have accelerated the development of industrial electric furnaces. It makes the development of new industrial electric furnaces more difficult and more advanced.

Compared with flame kilns, electric furnaces have many advantages:

1. High thermal efficiency. The heating furnace does not need to burn flue gas as a heat transfer medium, there is no heat loss caused by exhaust gas, the space heat intensity is high, and it can reach a very high temperature.
2. Good product quality. The atmosphere in the furnace is clean, the furnace temperature can be controlled, the temperature field is uniform and stable, and it can meet the requirements of various firing systems.
3. It can be fired in various artificial atmospheres. For example, products can be fired in N2, Ar, H2, O2 and other atmospheres.
4. Simple equipment. Small footprint, saving equipment investment.
5. Easy to operate. Good working conditions.

However, the auxiliary equipment of the electric furnace is relatively complex, and the installation cost and electricity cost are high.

Industrial electric furnace is a comprehensive application technology. It requires designers and researchers to have a solid theoretical foundation in heat transfer, gas mechanics, mechanics, electrical engineering, microelectronics and materials science. They should also have rich production practice experience and professional knowledge related to processing and manufacturing.

Modern industrial electric furnaces are highly mechanized and automated, and are computer controlled and managed. Industrial electric furnaces are facing comprehensive technological innovations. They need to transform existing industrial electric furnaces, design and develop new energy-saving and multi-purpose electric furnaces, study key furnace components, continuously improve their technical performance, form specialized production, digest and introduce advanced technologies, and improve the overall design and manufacturing level of my country's electric furnace industry.
