本文介绍了硼泥特性、凌钢８ｍ￣２竖炉及张钢、邢钢、鞍钢等烧结厂添加硼泥的工业性试验和高炉冶炼试验。试验表明：硼泥可以降低球团焙烧温度７０－１００℃，提高球团矿强度；降低烧结矿自然粉化率和低温还原粉化率，提高高炉产质量，降低焦比，获得了明显的经济效益。本文还阐述了硼泥在烧结球团过程中的作用机理。
This paper introduces the characteristics of boron mud, Lingang Steel 8m ~ 2 shaft furnace and Zhang Gang, Xing Steel, Anshan Iron and Steel Company, such as the addition of boron sludge industrial test and blast furnace smelting test. The results show that the boron mud can reduce the pellet roasting temperature from 70 to 100 ℃ and improve the pellet strength; reduce the natural pulverization rate and the low-temperature reduction pulverization rate of the sinter, raise the output and quality of the blast furnace and reduce the coke ratio, and obtain obvious economy benefit. The paper also describes the mechanism of action of boron mud in sintering pellets.
