冷轧双金属复层hardox450耐磨板表面光洁,加工优良,用于汽车、冰箱、洗衣机等家电,以及产业设备、各种建筑材料。随着经济发展,冷轧双金属复层hardox450耐磨板已被称为现代社会的必须材料。冷轧双金属复层hardox450耐磨钢板表面光洁,加工优良,用于汽车、冰箱、洗衣机等家电,以及产业设备、各种建筑材料。随着经济发展,冷轧双金属复层hardox450耐磨板已被称为现代社会的必须材料。冷轧双金属复层hardox450耐磨板的常见缺陷有以下三种:

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、边裂缺陷

1. Edge crack defect

边部出现的大型夹杂物富集是诱发边裂的主要根源之一。由于薄双金属复层hardox450耐磨钢板采用了漏斗型结晶器,结晶器内部的流动、传热的不均匀程度和液面波动情况比传统双金属复层hardox450耐磨钢板连铸时复杂,在浇铸过程中往往会造成卷渣,一部分卷渣残留在铸坯表面形成表面夹杂,其中较大的夹杂颗粒在铸坯边部沉积,造成边部大型氧化物夹杂的富集。

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、表面缺陷

2. Surface defects

酸洗后冷轧前带钢表面的黑色线条状缺陷。冷轧带钢表面缺陷主要来自热轧基料缺陷,以热轧双金属复层hardox450耐磨板表面夹杂类缺陷为主,冷轧生产线自身产生缺陷的可能性很小。

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、氧化铁皮压入缺陷

3. Defects of iron oxide sheet pressing

未完全除净的一次氧化铁皮在随后的轧制过程中被压入管带中造成管带表面缺陷。二次除鳞水未开等原因是造成二次氧化铁皮压入缺陷产生的关键。缺陷跟踪结果表明,氧化铁皮压入缺陷在随后的酸洗和冷轧过程中基本可以消除,对冷轧双金属复层hardox450耐磨板基本不造成影响。

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.
