1.90年代应着重考虑的问题 1.1我国钢铁工业仍是“三个不适应”,而品种质量问题更为突出“七五”期间,累计进口钢材6500×10~4t,相当于同期国内生产钢材的32％。长期以来,我国钢材结构基本上以型材、线材为主。1989年我国板管比约为37％。随着运输、能源,轻工等部门的发展,对板管的需求越来越多,要求越来越高。由于我国钢材产品结构不合理,还严重影响了我国机械制造业的发展。我国不少钢材产品质量标准低,性能不稳定。目前按国际标准和国外先进标准组织生产的钢材只有20～30％。不少部门的引进 1. Problems to be Considered in the 1990s 1.1 The steel industry in our country is still “three unsuitable” and the quality problems of varieties are more conspicuous. During the “Seventh Five-Year Plan” period, the total imports of steel products were 6500 × 10 ~ 4t, equivalent to 32% of the domestic production of steel products %. For a long time, the basic structure of steel in China mainly profiles, wire-based. In 1989, the ratio of plate and tube in our country was about 37%. With the development of transportation, energy, light industry and other departments, the demand for slab pipes is increasing and the demand is getting higher and higher. Due to the unreasonable structure of China’s steel products, but also seriously affected the development of China’s machinery manufacturing industry. Many Chinese steel products, low quality standards, performance instability. At present, only 20-30% of the steel produced according to international standards and advanced foreign standards is produced. Many departments to introduce
