90年代以至可以预见的未来岁月里,钢铁作为重要的结构材料和某些方面量大面广的功能材料的地位不会有根本性的改变。 1.基本态势从世界范围看,90年代对钢铁的数量需求将是在起伏波动中适度地增长(见图1),国际钢铁协会预计,2000年世界钢需求量将达到7.9亿吨,大约年均上升0.8％。还有人预计,世界钢产量90年代将以平均每年1.3％的速度增长。在质量、品种方面,总的趋势是要求越来越高,而在成本方面的竞争也将越来越激烈。与其他材料相比,钢材价格上升的总趋势相对慢些。钢铁产品不会再象1974～1986年间那样被其他材料占领其固有的市场(虽然是小量的)。90年代基本建设、基础设施方
From the 1990s to the foreseeable future, there will be no fundamental change in the status of steel as an important structural material and in some aspects of a wide range of functional materials. 1. Basic Situation From a global perspective, the demand for steel in the 1990s will be modestly increased in fluctuation (see Figure 1). The International Iron and Steel Institute estimates that in 2000 the world demand for steel will reach 790 million tons Both up 0.8%. Still others predict that world steel production will grow at an average annual rate of 1.3% per year in the 1990s. In terms of quality and variety, the general trend is that the requirements are getting higher and higher, and the cost competition will also become more and more intense. Compared with other materials, the general trend of steel prices is relatively slow. Iron and steel products will no longer be dominated by other materials (as small as they were) from 1974 to 1986. 90s infrastructure, infrastructure
