Abstract:In order to study the surface sheet crack in medium and heavy plate, the methods such as the scanning electron microscope and optical metallograph were used to analysis the defect. The results showed that disabled bearing cage made of Cu was pressed into slab, and then the crack formed and enlarged during rolling. The failure of bearings was caused by the bad cooling and lubrication conditions under high temperature. By changing the material of bearing cage, improving the lubrication and cooling conditions, the defect of surface sheet cracking was solved effectively.
