一、概况 在七十年代,微量合金化和控制轧制作为提高钢板机械性能的有效手段已被广泛应用。然而,由于输油管线、海上采油平台、大型高压容器、船舶和工程机械等工业对钢板的性能要求日益提高,对产品厚度要求在10至50毫米之间,并要求可焊性优良,故采用常规控制轧制方法已不能满足钢板高性能的要求。 为了达到现代化要求,必须生产出具有如下高性能的钢板:
First, an overview In the seventies, microalloying and controlled rolling as an effective means to improve the mechanical properties of steel has been widely used. However, due to the increasing performance requirements of steel plates in industries such as oil pipeline, offshore oil platform, large-scale high-pressure vessels, ships and construction machinery, the thickness of the product is required to be between 10 and 50 mm and the solderability is good, so conventional Controlled rolling method can not meet the high performance requirements of steel. In order to meet the requirements of modernization, it is necessary to produce steel plates with the following high performance:
