Heat treatment process of production and processing is important in the process of heat treatment, the radiant tube plays an important role.Radiant tube adopts advanced production technology and material, has the characteristics of high temperature resistant, corrosion resistant, can use for a long time, high heat treatment technology, also plays an important role on the development of industry.The heat treatment technology is very advanced, and the heat treatment equipment such as radiant tube and furnace bottom roll these auxiliary equipment is tested on its advanced nature.Heat treatment technology are usually very strict indicators, so all the auxiliary equipment also needs and in accordance with the provisions of relevant indicators for production to use.Because only the equipment level raised, then can guarantee the quality of production object, to some extent also save the cost, improve the production of products, increase the efficiency of enterprises.Now the improvement of production technology, as well as the continuous development and application of the material, the emergence of a lot of high temperature resistant material provides conditions for the radiant tube production, improve the performance of the equipment, but also pay attention to the maintenance of equipment, maintenance, the problems in time to avoid the unnecessary loss.
