45# Seamless Steel Pipe Defect Control
1. Control the carbon content in the steel as much as possible to avoid the peritectic reaction zone and the upper or lower control limits. 2. The vibration stability should be monitored to ensure that the lateral deflection of the vibration is not more than 0.2 mm and the longitudinal deflection is not more than 0.4 mm. 3. Strict nozzle assembly ensures good nozzle alignment, prevents drift, and ensures uniform solidification of shaped pipes. 4. Improve the accuracy of the fan section, especially the mold and the zero part. If severe bending is found, replace the zero part of the pinch roller. 5. Control the superheat of the steel in the 45# seamless steel tube , determine the appropriate drawing speed system, and prevent the outer casing from being too hot and the drawing speed too thin. 6. Select the appropriate slag according to the characteristics of the special steel pipe, appropriately increase the viscosity of the mold slag, improve the heat transfer unifo...
