国外热轧中高碳钢板的开发现状及其借鉴

DEVELOPMENT STATUS OF FOREIGN HOT ROLLED MEDIUM AND HIGH CARBON STEEL PLATE AND USE FOR REFERENCE

热轧中高碳钢板广泛应用于机械制造和汽车等领域,市场需求量较大。国外钢铁公司JFE、新日铁住金、浦项、安赛乐米塔尔等开发的典型中高碳钢产品成系列化、性能优良、附加值高。国内热轧中高碳产品与国外相比还存在着较大的差距,一些高端的产品仍需要进口,需进一步加快中高端热轧中高碳钢产品的研究和开发。

Hot rolled medium and high carbon steel plates were widely used in machinery and automobile manufacturing field etc. The medium and high carbon steel plates developed by foreign companies JFE, Nippon Steel ＆ Sumitomo Metal, Posco, Thyssen Krupp and ArcelorMittal realized seriation, excellent performance and high added value. The big gap of hot rolled medium and high carbon steel plates between domestic and foreign was pointed out; some high value products need to be imported. It is necessary to accelerate the development of high added value medium and high carbon steel plates.
