| Abstract: | The process of all these elements such as potassium, sodium, zinc, lead and chloride which are enriched circularly in blast furnace is analyzed with regard to the reaction behavior of harmful elements in blast furnace as well as the catalytic action to coke degradation caused by these harmful elements. The effect of harmful elements on thermal properties of cokes is mainly discussed and therefore the harmfulness of several harmful elements to cokes and iron- making by blast furnace is clearly confirmed. Finally control measures are proposed based on the characteristic of circulating enrichment of these elements. |
