How the furnace works The fuel is burned in the furnace to release heat, and the heat is transferred to the furnace tube (mainly through radiation heat transfer in the radiation chamber, and mainly through the flue gas convection heat transfer in the convection chamber), and the heat is transferred through the furnace tube wall to the material in the tube, So as to achieve the purpose of heating the material.The importance of brazing holding time Second, the composition and function of the tubular heating furnace 1. Composition A tubular heating furnace is generally composed of four parts: a burner, a radiation chamber, a convection chamber and a chimney. Furnace tubes are installed in the radiation chamber and convection chamber; burners are installed at the bottom, side walls or top of the radiation chamber; flue baffles are installed in the chimney. Advanced furnaces are also equipped with air and fuel ratio control and regulation systems.Low pressure vacuum carburizing process of Cr17Ni2 stainless steel 2. Function (1) Burner: It mainly provides high temperature heat source for the heating furnace. (2) Radiation chamber: also known as the furnace, it is the core part of the tubular heating furnace. The fuel ejected from the nozzle is burned in the furnace, and due to the high temperature of the flame, the heat is mainly transmitted by radiation. Part of it is accepted by the furnace tube, and part of it increases the temperature of the furnace wall, and the furnace wall reflects the heat back and transmits it to a part of the furnace tube. Vacuum heat treatment of high speed steel (3) Convection chamber: The temperature of the flue gas leaving the radiation chamber is usually controlled at 700-900 °C, and a convection chamber can be set up to make use of this part of the heat. Convective heat transfer is mainly in the convection chamber. In order to improve the heat transfer efficiency, the flow direction of the oil in the pipe is opposite to the flow direction of the flue gas outside the pipe. (4) Chimney: The temperature of the flue gas leaving the convection chamber is generally 300-450 ℃. In order to reduce the heat loss of the heating furnace and improve the thermal efficiency of the heating furnace, the air preheater can be used to recover this part of the heat, so that the temperature of the flue gas can be reduced to 200 ℃ about. The density of the high-temperature flue gas in the chimney is smaller than that of the air outside the chimney to generate a pulling force, so the flue gas can be automatically discharged. The higher the chimney, the greater the draw force of the furnace and the greater the air volume entering the radiation chamber. In order to control the proper drawing force, an adjustable baffle should be added in the chimney to maintain a proper negative pressure in the furnace.Battery cooler vacuum brazing
