预计到21世纪中叶,我国的钢材需求可能超过2亿t/a。目前1亿t/a的规模已颇为不易,国家为此投入了6000亿元。如果再增加1亿t/a的产量,将再投入10000亿元,国家财力、能源、资源、环境和运输等均无法承受。“国家重点基础研究规划”首批项目之一“新一代钢铁材料的重大基础研究”,就是要寻求一套解决方案,即发展新型高效钢材,以1t顶几吨现有钢材。 It is estimated that by the middle of the 21st century, China’s demand for steel may exceed 200 million t / a. At present, the scale of 100 million t / a has been rather difficult, and the state has invested 600 billion yuan for this purpose. If we increase the output of 100 million t / a, we will invest another 1,000 billion yuan to make it impossible for the country’s financial resources, energy, resources, environment and transportation to sustain it. One of the first projects of “National Key Basic Research Program”, “a great fundamental research of a new generation of steel materials,” is to find a solution to develop new high-efficiency steel materials with 1t tops of existing steel products.
