In order to study the metallurgical properties of the pellet, experimental smelting with pellet-ratio up to 90% were performed in a 100m~3 blast furnace. Samples were taken from the furnace stack at different levels. Changes of pellet properties, such as reducibility at high temperature, strength after reduction, pulverization, softening, fusion, sticking, etc., in the operation of the furnace were investigated. The metallurgical effect of pellet in the blast furnace operation was studied, The result...

In order to study the metallurgical properties of the pellet, experimental smelting with pellet-ratio up to 90% were performed in a 100m~3 blast furnace. Samples were taken from the furnace stack at different levels. Changes of pellet properties, such as reducibility at high temperature, strength after reduction, pulverization, softening, fusion, sticking, etc., in the operation of the furnace were investigated. The metallurgical effect of pellet in the blast furnace operation was studied, The result shows that the pellet behaves better than the sinter. When the pellet are used to replace the sinter, the operating indices has been improved remarkably. However, the degree of improvement of the operating indices is not directly proportional to the increase of the pellet-ratio, It declines as the ratio raises. Thus, it is important to increase the high temperature

为了研究球团矿的冶炼性能,在100米~3高炉上进行了配比达90%冶炼试验和炉身取样.一方面考查球团矿在高炉实际冶炼中高温还原性,还原强度,粉化,软化,融熔,粘结等性能变化,另一方面分析了球团矿对高炉冶炼的影响.试验表明,球团矿比烧结矿冶炼性能更好,以球团矿代替烧结矿,冶炼指标显著改善.但随着球团矿配比增加,冶炼指标改善幅度变小.在保证还原性的情况下,改善球团矿的高温强度,提高软化温度是高炉大量使用球团矿的关键.

With the development of iron making technology in blast furnace, it is necessary to manufacture metallurgical coke of high quality. This article has made a detailed analysis of the coke quality of some major steel plants and discussed the effect of coke quality on the production of blast furnace. Since recent years, the quality of metallurgical coke in our country has been much worse in compare with the past best record. While as in other important iron and steel producing countries the coke quality is improved in order to satisfy the requirement of large blast furnace. For improving the coke quality in our country, this paper introduces some new ways in coke manufacture, for example, to select a appropriate low ash content in washed coal, to adopt the new technology of coal handling, including blending briquettes, preheated coal and selective crushing etc. Some proposals for improvement of coke quality are suggested.

随着高炉的大型化和炼铁技术的发展,对冶金焦炭提出了更高的要求.本文对我国冶金系统一些重点企业的焦炭质量及其对高炉生产的影响进行了分析.近几年来,我国冶金焦炭质量和历史最好水平相比有所下降.而国外几个主要产钢国家为了满足大型高炉冶炼需要,焦炭质量都不断提高.为了提高我国焦炭质量,介绍了几种改善焦炭质量的新途径,如:选择合理的精煤灰份;采用备煤新工艺,包括煤料的选择破碎、配入型煤炼焦、预热煤炼焦等.并提出了改善焦炭质量的几点建议.

Three procedures of cold consolidation of iron-ore and ore-coke pellets using sponge iron powder as a binder (without salt and other additions) have been developed. 1. Cold consolidation of green pellets, 2. consolidation of green pellets after drying. 3. cold consolidation and then drying. The cold consolidated pellets have a compressive strength of 10-20kg/pellet (pellet diameter 8-10mm), suitable for direct charging into rotary kiln and allowing a high temperature (>850℃) at the end of the kiln. Mechanism...

Three procedures of cold consolidation of iron-ore and ore-coke pellets using sponge iron powder as a binder (without salt and other additions) have been developed. 1. Cold consolidation of green pellets, 2. consolidation of green pellets after drying. 3. cold consolidation and then drying. The cold consolidated pellets have a compressive strength of 10-20kg/pellet (pellet diameter 8-10mm), suitable for direct charging into rotary kiln and allowing a high temperature (>850℃) at the end of the kiln. Mechanism of consolidation of these pellets is studied. Their metallurgical properties appear superior to ordinary oxidized pellets. Direct reduction tests of cold consolidated pellets in a semi-industrial rotary kiln (inner diameter 1.1×1.4m) gave a metallization rate of about 95%, with less than 6% powder and at the same time without reoxidization and ring formation. A new scheme of cold consolidation of iron-ore pellets and their direct reduction in the rotary kiln in commercial scale is proposed.
