Information
       While using the tempering furnace, it is necessary to pay attention to the factors that affect the combustion temperature. Generally, preheating the air and fuel can increase the combustion temperature, and the higher the preheating temperature, the higher the combustion temperature, especially the significance of preheating the air. The higher the calorific value of the tempering furnace fuel, the higher the combustion temperature is. Therefore, when higher temperature is required, high-quality fuel with high calorific value should be selected.

        At the same time, the quenching oil accumulated throughout the year in the tempering furnace forms a thick oily layer. During the tempering process, the oil vapor adheres to the work piece, causing serious oil stains on the surface of the work piece after tempering, and it is easy to adhere to sand during the shot blasting process. The traditional method to remove oil stains can only be manually cleaned. It is recommended to clean it regularly.

 
 
  The tempering furnace minimizes the heat loss of the furnace, such as the heat loss of the furnace hull, the heat storage loss, the radiant heat loss when opening the furnace door, etc., as far as possible to ensure the complete combustion of the fuel, reduce the mechanical incomplete combustion and the chemical incomplete combustion, and ensure complete combustion. In this case, the excess air should be minimized and the use of oxygen-enriched air blast should be used.
