Causes of Surface Cracks in Wire Rod Rolling Mill

The main reasons for surface cracks of wire rod out of high-speed wire rod rolling mill are that the uneliminated cracks (longitudinal or transverse), subcutaneous bubbles and non-metallic inclusions on the billet will cause cracks on the surface of wire rod. If the pinholes on the continuous casting slab are not eliminated, the linear hairlines of the finished products will be caused by the extension, oxidation,

What is Wire Rod Mill? - Bar Wire Rod Rolling Mill ...

Wire rod is the product with the smallest interruption surface size. The total elongation coefficient is large when the product is rolled from billet to finished product. The rolling piece is usually rolled only once on each rolling mill. Therefore, wire rod mill is the rolling mill with the largest number of stands and the finest division of labor in the hot rolled section.

Rolling Mill - an overview ScienceDirect Topics

It has long been recognized that some, if not most, of the variations in thickness of strip produced by a cold-reduction mill have their origin in the hot rolling process. For example, it has been shown that in many coils of metal produced by a cold mill several heavy areas can be identified which result from water-cooled skids in the slab-heating furnace preceding the hot-strip mill.
