Hardox450 cold rolled bimetal clad hardox450 wear-resistant plate has a smooth surface and excellent processing. It is used in automobile, refrigerator, washing machine and other household appliances, as well as industrial equipment and various construction materials. With the development of economy, cold rolled bimetal clad hardox450 wear-resistant plate has been called the necessary material in modern society. Hardox450 cold rolled bimetal clad hardox450 wear-resistant steel plate is smooth and well processed, and is used in automobile, refrigerator, washing machine and other household appliances, as well as industrial equipment and various construction materials. With the development of economy, cold rolled bimetal clad hardox450 wear-resistant plate has been called the necessary material in modern society. The common defects of hardox450 cold rolled bimetal clad hardox450 wear-resistant plate are as follows:
1. Edge crack defect
The enrichment of large inclusions at the edge is one of the main causes of edge crack. Because the funnel mould is used in the thin bimetal clad hardox450 wear-resistant steel plate, the flow, heat transfer inhomogeneity and liquid level fluctuation in the mould are more complicated than that of traditional bimetal clad hardox450 wear-resistant steel plate. In the casting process, slag roll will be caused, and some of the slag remains on the surface of the slab to form surface inclusions, and the larger inclusion particles are on the edge of the billet The deposition of the part results in the enrichment of the large oxide inclusions at the edge.
2. Surface defects
Black line defects on the surface of strip before cold rolling after pickling. The surface defects of cold rolled strip mainly come from the defects of hot rolled base materials, mainly including inclusions on the surface of hardox450 wear-resistant plate with hot-rolled bimetal layer, and the possibility of defects in cold rolling production line is very small.
3. Defects of iron oxide sheet pressing
The surface defects of the strip are caused by the incomplete removal of the primary oxide sheet which is pressed into the strip during subsequent rolling. The key to the defect of the secondary scale pressing is that the secondary descaling water is not open. The results of defect tracking show that the defects can be eliminated in the subsequent pickling and cold rolling process, and the effect on hardox450 wear-resistant sheet of cold-rolled bimetal clad layer is not affected.
