The heating furnace is divided into: a preheating section, a heating section, a heating section, and a soaking section; the segmentation method is to divide the furnace into four sections along the length direction. Each heating section is composed of upper heating and lower heating, that is, when adjusting the furnace temperature of each heating section, adjust the upper and lower burners at the same time.X6332 / X6336 SERIES UNIVERSAL TURRET MILLING MACHINE WITH HORIZONTAL According to production needs (such as output, heating process requirements, etc.), the temperature of the heating section, the heating adjustment and control of the second section and the soaking section. The heating furnace is controlled by: through the temperature of the temperature control instrument (or manual adjustment). The temperature controller automatically adjusts the opening of the electric butterfly valve on the air main pipe to adjust the air pressure (and adjust the air flow accordingly).X6436 SERIES HEAVY DUTY UNIVERSAL SWIVEL HEAD MILLING MACHINE The air pressure is transmitted to the air/gas proportional valve by the pressure signal collected by the copper tube. Through the function of the proportional valve, it is directly adjusted according to the natural gas flow rate with a reasonable air-fuel ratio to realize automatic control of the furnace temperature.Laminated evaporator vacuum brazing Check whether the valves before each burner (natural gas regulating valve and air butterfly valve) are open or closed. Release and make sure all natural gas regulator valves (main control valve and front nozzle control valve) are fully closed. Check to make sure the front of the burner is clear of debris and blockages.Vacuum Heat Treatment of Engine Cylinder Block Die-casting Mold
