本文扼要地阐述了攀钢高炉投产以来炉料结构的演变。1970年7月至1978年2月为采用全钒钛烧结矿冶炼期,由于粘渣、泡沫渣等问题,高炉利用系数低,焦比高。1978年3月以来,采取钒钛烧结矿配加10—15%的普通块矿炉料结构,突破了生产设计水平.提出了进～步完善炉料结构的设想,当前应创造条件增加钒钛烧结矿富矿粉配入量到12％左右,减少块矿入炉。从长远考虑,有待白马矿的开发,生产酸性球团矿配高碱度钒钛烧结矿冶炼,将有利于改善技术经济指标。
This article gives a brief account of the evolution of charge structure since the BF was put into operation. July 1970 to February 1978 for the all-vanadium titanium sinter smelting period, due to sticky slag, foam slag and other issues, blast furnace utilization factor is low, high coke ratio. Since March 1978, adopting vanadium-titanium sinter with 10-15% ordinary lump ore charge structure has broken through the design level of production, and put forward the idea of improving the charge structure with ~ step. At present, it is necessary to create conditions to increase vanadium-titanium sinter The amount of rich ore dosing is about 12%, reducing lump ore into the furnace. From the long-term consideration, pending the development of Baima Mine, production of acid pellets with high-basicity vanadium-titanium sinter smelting, will help improve the technical and economic indicators.
