十几年来,鞍钢铁厂成功地采用了唢吹重油、煤粉的新技术。在学习鞍钢实行大喷吹量提高喷吹效果的一系列宝贵经验的基础上,提出如下几点认识,供进一步商榷讨论。 一、影响炉缸热状态的诸因素 众所周知,保证高炉正常生产的前提条件是炉温充沛、渣铁流畅,即炉缸应有良好的热状态。实践和理论都表明,炉缸热状态是高炉冶炼条件、冶炼制度和炉内物理化学反应过程
For over a decade, Ansteel Iron and Steel has successfully adopted the new technology of blowing heavy oil and pulverized coal. On the basis of learning a series of valuable experiences of Anshan Iron and Steel Group to achieve a large injection rate to improve the injection effect, put forward the following points for further discussion. First, the factors that affect the hot state of hearth As we all know, to ensure the normal production of the blast furnace is a prerequisite for adequate temperature, slag iron smooth, that is, the hearth should have a good thermal state. Practice and theory have shown that the hearth thermal state is the blast furnace smelting conditions, smelting system and furnace physicochemical reaction process
