Discussion of steel wire direct drawing production without intermediate heat treatment

To analyze some important factors such as wire rod quality, wire rod surface pre-treatment, lubrication condition and cooling effect which affect steel wire drawing directly. By controlling these important factors strictly, steel wire direct drawing can be realized without intermediate heat treatment. The processes adopted by direct drawing and traditional wire drawing, the properties of finished wire were compared. Improved direct drawing process was given out. Tensile strength average value of direct drawing and traditional wire drawing was 2081,1 780 MPa respectively, torsion value was 36, 42 respectively tensile strength average value of traditional drawing was 1 780 MPa, torsion value was 42. Comparing with traditional wire drawing process, direct drawing process can reach a certain situation steel wire properties requirement. It is suitable for the requirement of present energy saving and environment protection, cost saving and efficient production.
