前言目前,国内的船板生产,由于采用了控制轧制和严格的技术操作规程,使轧制出的船板无论在机械性能和同板差上,都达到了国际上通行的英国劳埃德船板标准。但是,轧好的钢板在矫直之后,再经冷却、剪边、切头切尾等精整工序,有相当一部份船板因表面严重擦伤,以及外形几何尺寸精度上的偏差等问题而被降级,甚至于报废,这无疑是十分可惜的。 Preface At present, the domestic ship board production, due to the use of controlled rolling and strict technical procedures, so that the rolling ship plate in terms of mechanical properties and plate with the same, have reached the internationally popular British Lloyd Ship board standard. However, after the straightening of the rolled steel is rectified, there are a number of problems such as serious scratches on the surface of the ship due to the finishing processes such as cooling, shearing and cutting of the cut ends, as well as variations in the accuracy of the shape geometries It is undoubtedly a pity that they have been downgraded or even scrapped.
