鼓风炉连续放渣的基本概念,自1902年Lincoln发表他的论文后就已被揭示出来。连续放渣系统首先是在铜鼓风炉上应用的。1955年J,T Roy进行了研究,这一系统乃运用于铅鼓风炉。随后,连续放渣也相继用于其他低强度的有色冶炼鼓风炉。1985年,澳大利亚的硫化物公司在他们的铅锌密闭鼓风炉上采用了连续放渣系统。该公司发现,其所牵涉的物理原理,与早期的研究经验没有什么差异,但由于ISF炉与别的有色冶金炉其还原气氛的强度不同,从而黄渣的稳定性不同,而这一点对连续放渣系统的设计和操作,都有很重要的作用。
The basic concept of continuous slag discharge in blast furnaces has been revealed since Lincoln published his paper in 1902. Continuous slag discharge system is first applied to the copper blast furnace. In 1955, T Roy studied the system for lead blast furnaces. Subsequently, the continuous slag discharge has also been used for other low-intensity non-ferrous smelting blast furnace. In 1985, Australian sulphide companies employed a continuous slag removal system on their lead-zinc enclosed blast furnace. The company found that the physical principles involved were not different from those of earlier studies, but the stability of the yellow dross was different due to the difference in intensity of the reducing atmosphere between the ISF furnace and the other non-ferrous metallurgical furnaces, Grading slag system design and operation, have a very important role.
