一、前言 船体结构钢在造船材料中占有极其重要的位置。可以预计,在今后相当长的时间内以钢材造船为主的局面不会改变。 我国对船体结构钢的研制已有二十多年的历史。在这段时间内,对新钢种的开发与应用取得了很大成绩。应该特别指出的是,近几年来,由于重视了新钢种的应用研究,已大大加快了船体结构钢的研究进度。为适应我国造船工业的发展与要求,分析我国船体结构钢的现状,并对今后的开发与应用研究工作以及有关技术政策进行讨论是十分有意义的。
First, the foreword Hull structural steel in shipbuilding materials occupy an extremely important position. It can be expected that the situation dominated by steel shipbuilding will not change for a long time to come. China’s research on the structural steel has been more than 20 years of history. During this time, great achievements have been made in the development and application of new steel grades. It should be particularly pointed out that in recent years, due to the emphasis on the application of new steel species, has greatly accelerated the progress of the research of structural steel hull. In order to meet the development and requirements of China’s shipbuilding industry, the status quo of China’s hull structural steel is analyzed. It is of great significance to discuss the future development and application of research and related technical policies.
