This calciner is developed on the basis of summarizing the rich experience of many out-of-kiln decomposition methods. It is formed by adding a TSD calciner between the kiln and the C5 cyclone. It mainly consists of the swirl pre-combustion chamber, the main furnace and the ascending pipe to form the calciner area.LARGE CNC HORIZONTAL LATHE There is a shrinkage between the kiln tail smoke chamber and the main furnace to balance the pressure between the kiln and the calciner. The wind speed at the constriction can generally reach 30-50 m/s, and the negative pressure is 0.8-1.0 kPa. HIGH PRECISION CNC LATHE The tertiary air drawn from the cooler enters the furnace at a certain speed from the upper part of the pre-combustion chamber in a tangential direction. The raw material coming down from the C4 cyclone is fed into the airflow before the tertiary air enters the furnace, and a spreader is installed there to make the air and material mix into the furnace.Tips for vacuum brazing problem Intense vortex motion is generated inside it, and due to the centrifugal force, the central part of the pre-combustion chamber becomes the equilibrium phase area of the material concentration, and the peripheral part becomes the dense phase area of the material.Research on Vacuum Heat Treatment Technology of Cr12 Steel
