Heat treatment furnace is an important equipment in industrial production, the application of radiation tube in the heat treatment furnace has a great advantage.2) products are of good quality.The whole furnace is divided into 24 temperature control area, the pulse type ON - OFF control burner, greatly improved the precision of temperature control, make steel plate from an arbitrary point temperature and target temperature deviation is less than + 15 ℃, and ensure the released plate temperature uniformity of the length and width, all control within plus or minus 10 ℃.3) low energy consumption.Reduce the energy consumption is the direction of the industrial development, energy conservation and consumption reduction is the theme of development, the application of the radiant tube to a certain extent, also reduced the energy consumption.4) small heat loss.The heat exchanger, radiant tube is used to complete the stove can be combustion-supporting air preheat to 500 ℃, the effective utilization of flue gas waste heat.
