Some cracks have inclusions and decarbonization on both sides. 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
Mill Cracks In The Mill Ends. The rolls of rolling mill may break in practical application of the roll and the cyclic cooling of the cooling water will cause the wear of the roll and the appearance of hot cracks example in the rolling process the rolls will be affected by. Learn More.
2020-7-15 · These cracks are usually formed in the pipe mill for seam welds or during pipeline construction for girth welds. Cold cracking in weld metal requires the presences of hydrogen, a susceptible weld metal microstructure and stress, so cracks typically form in the longitudinal direction. While cold cracking generally occurs during or just after the

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 7.17 Reduction of Local Buckles. Even though the cold mill itself may cause local buckles, the majority of the local buckles are caused by the feed stock from the hot mill (Melfo et al., 2006). Therefore, proper monitoring of the hot band profile and mechanical properties will be the first choice to reduce local buckles.
