本文叙述了冷粘结球团在瑞典格兰耶斯贝里耶工业性球团厂投产后的发展。列出了高炉球团的化学成分和机械特性。介绍了粘结剂加工和添加垫料技术的改进,特别介绍了降低球团产品碱度的措施。评论了低碱度对冷粘结球团在熔化前的低温碎裂、膨胀性和软化性等冶金特性的影响,探讨了使用冷粘结球团冶炼的高炉操作,强调了低碱度对操作参数的影响。对格兰耶斯冷粘结球团法与普通造块方法的投资和加工费用做了经济比较。最后简要探讨了格兰耶斯冷粘结球团法进一步应用的有利条件。
This article describes the development of a cold-bonded pellet after it was put into operation at the Granys Berry industrial pellet plant in Sweden. The chemical composition and mechanical properties of blast furnace pellets are listed. The improvements of binder processing and padding technology are introduced, especially the measures to reduce the alkalinity of pellet products. The effects of low alkalinity on metallurgical properties such as chilling, swelling and softening properties of cold-bonded pellets before melting were reviewed. The blast furnace operations using cold-bonded pellet smelting were discussed, emphasizing the effect of low alkalinity on operation Effect of parameters. An economic comparison of the investment and processing costs of Glencore Cold Bonding Pelletizing and the common method of making blocks is made. Finally, the favorable conditions for the further application of Glenn’s cold bonding pellet method are briefly discussed.
