The ceramic industry plays an important role in social construction, national defense science and people’s lives. It not only has a close relationship with human’s daily life, but with the development of science and technology, it has surpassed daily use, construction and general industrial use. Range, and applied to cutting-edge materials such as electrons and atomic energy.
An important process in the production of ceramics is sintering, which is carried out in thermal equipment during firing. The thermal equipment here refers to the box furnace and its auxiliary equipment. With the development of science and technology, the original materials cannot be adapted in many cases and require special processing. The raw materials are mostly high-purity oxides, carbides, nitrides and other high-temperature materials. The manufacture and inspection of these modern heat-resistant materials need to be carried out at high temperatures. Therefore, new high-temperature equipment has also been developed accordingly. </div>
At present, in the production and scientific research of electronic kiln ceramics, high-temperature ceramics and other special ceramics, various electric furnaces are emerging one after another. Higher and higher requirements are put forward for circuits in terms of high temperature, atmosphere and pressure. Electric tunnel kilns, high-temperature hydrogen wire furnaces and tungsten rod furnaces have been widely used. Compared with flame kilns, electric furnaces have many advantages: electric furnaces have high thermal efficiency, compact heating space, high space thermal intensity, and higher temperatures can be obtained, which is difficult to achieve with flame kilns, and the product quality is good, and the atmosphere in the furnace is relatively high. It is clean, at the same time the temperature can be controlled very accurately, and it is easy to realize automatic production. The electric furnace does not need a combustion chamber, exhaust fan or chimney, has a simple structure and a small footprint, and can be fired in a variety of artificial atmospheres. Because there is no influence of extremely high temperature combustion chamber and furnace ash, the service life of refractory materials is long.
Box-type resistance furnace has a wide range of use, different electric heating elements can be used at different temperatures, and the firing range of products is also relatively wide, and the firing range is also relatively wide, suitable for large, medium and small products For the production and processing, the furnace chamber of the box-type resistance furnace is square, and different specifications can be customized according to the specific requirements of the size. In addition, the box-type resistance furnace is economical and economical, the manufacturing process is relatively simple, can have a long service life, and the cost performance is high.
