Problems solved by technology

[0003] In addition, in the process of brass production, the rod blanks pulled out of the melting furnace are drawn by a giant drawing machine or a large drawing machine and then enter the subsequent process. However, internal cracks and stress cracks in the wire core often occur during the giant drawing process. , distortion, drawing fracture, uneven thickness of the pipe, scratches on the surface of the product and other defects, to a certain extent, change the structure of the wire and enlarge the defects in the slab, which is not conducive to subsequent production
[0004] At present, due to the unreasonable ratio of some alloying elements in the alloy wire, the hardness and wear resistance of the material are not high, and the impact toughness and fracture resistance of the material are not good.
