Heating furnace is a kind of equipment specialized in heating treatment of product materials and workpieces produced, and its working principle is to work in a phase change heat mode, in an airtight container without non-condensable gases, through the heat generated by the combustion of fuels to the intermediary substances are heated. Heating furnace applications throughout the petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, pharmaceuticals and many other industry sectors. The structural composition of the heating furnace usually includes preheating section, heating section and equalization section, which are distributed along the length of the furnace chamber to ensure that the temperature of the material or workpiece is uniform in the heating process.
Heating furnace classification methods are diverse, according to the heating principle can be divided into thermal storage heating furnace, tube heating furnace, etc.; according to the heating method can be divided into tube heating furnace, air heating furnace, electric heating furnace, etc.; according to the use can be divided into petroleum heating furnace, industrial heating furnace, chemical heating furnace, etc.; according to the structure can be divided into the push steel type continuous heating furnace, walk-in continuous heating furnace, etc.. These classifications reflect the diversity and adaptability of heating furnace technology to meet the needs of different industries and specific applications.
In the design and use of heating furnace, the selection of refractory materials is crucial. The selection of refractory materials needs to take into account factors such as operating temperature, temperature changes, temperature gradients and flushing of high temperature furnace gases. For example, forging heating furnaces work at high temperatures, and the operating temperature is generally below 1400°C. Therefore, refractory clay bricks or refractory precast concrete blocks are required to build the roof and bottom of the furnace to ensure the durability and safety of the furnace. In addition, for key components such as nozzle bricks, refractory materials with high softening temperature, good thermal stability, strong slag resistance and appropriate dimensions need to be used to ensure the normal operation and prolong the service life of the heating furnace
