How to effectively extend the service life of 12Cr1MoV alloy pipes? Reduce friction. In the cold drawing process, effective lubrication can lower the coefficient of friction between the cold drawing die and the deformed metal surface, decrease surface friction energy consumption, reduce drawing force, and lower the consumption of drawing force. Minimize die wear. Effective lubrication can reduce wear on the die during cold drawing, which not only reduces production costs but also shortens the time for replacing and repairing dies, improves productivity, and reduces labor intensity, ensuring product size accuracy. Lower the surface roughness of 12Cr1MoV alloy pipes. Our 12Cr1MoV alloy pipes are required to have smooth inner and outer surfaces. Poor lubrication during cold drawing can result in surface roughness, bamboo-like joints, and even cracks in the drawn products, so effective lubrication is crucial to ensure the reduction of surface temperature in the cold-drawn 12Cr1MoV alloy pipes. When metal pipes undergo plastic deformation in the die, a significant amount of energy is required to overcome deformation forces and friction with the die wall, which also generates a lot of heat. Effective lubrication significantly reduces heat generation, ensuring pipe quality and reducing energy consumption. Reduce uneven distribution of internal stresses in cold-drawn products. The quality of lubrication can affect the distribution of internal stresses in the product. Sudden changes in stress distribution during cold drawing can severely degrade the mechanical properties of the drawn products. In cases of uneven stress distribution, excessively high local internal stresses can lead to product failure. Prevent rust on products. During the cold drawing process, phosphatization also serves as a rust inhibitor, enhancing the corrosion resistance of the cold-drawn products and extending their service life.
