建筑用钢品种开发和技术发展的趋势杨忠民1(1.北京市钢铁研究总院结构材料研究所)摘 要:建筑用钢是中国钢材消费最大的品种,快速发展的建筑业为建筑用钢品种的开发和应用提供了广泛的市场.中国建筑用钢品种的开发和应用已经取得了巨大进步,但是建筑用钢的科研和应用技术开发仍然相对落后.这包括钢材新品开发能力和建筑应用技术水平较低;高强度高性能钢材的消费比例偏低;冶金标准和应用技术规范更新滞后等等.中国建筑用钢的技术含量较低,至今仍属于基础类,低档次钢种,科研开发资金投入相对不足.建筑用钢品种的技术指标尚需进一步完善,尤其......
liner made of fire-resistant materials, the diameter of the sample was 30 mm, and the thickness was 2-3 mm. Then the ash and the liner were put into the furnace to be heated. Table 1 Ash compositions..., and new substances will be produced. The free energy among compositions of ash and fire-resistant materials during the slagging process will tend spontaneously to the minimum in order to reach a new......
