Development and application of box-type electric furnace

The ceramic industry plays an important role in social construction, national defense science and people’s life. It not only has a close relationship with human daily life, but also, with the development of science and technology, has gone beyond the scope of daily use, construction and general industrial use, and is applied to cutting-edge materials such as electricity and atomic energy.
An important process in the production of ceramics is sintering, which is carried out in the thermal equipment. The thermal equipment here refers to the box furnace and its auxiliary equipment. With the development of science and technology, the original materials can not adapt to many situations, and need special processing. Most of its raw materials are high-purity oxides, carbides, nitrides and other high-temperature materials. The manufacturing and inspection of these modern heat-resistant materials need to be carried out at high temperature. Therefore, new high-temperature equipment has also been developed accordingly.
At present, in the production and research of electronic kiln ceramics, high-temperature ceramics and other special ceramics, various electric furnaces emerge in endlessly. Higher and higher requirements are put forward for the circuit in terms of high temperature, atmosphere and pressure. Electric tunnel kiln, high-temperature hydrogen wire furnace and tungsten rod furnace have been widely used. Compared with flame furnace, electric furnace has many advantages: high thermal efficiency, compact heating space, high thermal intensity in space, and higher temperature can be obtained, which is difficult for flame furnace to achieve. Besides, the product quality is good, the atmosphere in the furnace is relatively clean, and the temperature can be controlled abnormally accurately, which is easy to realize automatic production. The electric furnace does not need combustion chamber, exhaust fan or chimney, and has simple structure and small floor area, It can be fired in various artificial atmospheres. Because there is no influence of extremely high temperature combustion chamber and furnace ash, the service life of refractory materials is long.
The box-type resistance furnace has a wide range of applications. Different electric heating elements can be used at different temperatures, and the firing range of products is also relatively wide. It is also suitable for the production and processing of large, medium and small products. The furnace of the box-type resistance furnace is square, and different specifications can be customized according to the size of specific requirements. Moreover, the box resistance furnace is economical, simple in manufacturing process, long in service life and high in cost performance.
