Abstract

Abstract

The technical modernization of No.1 blast furnace in the relining for the fourth generation lifetime at PZH Steel was introduced. The modernization includes:increasing the capacity of blast furnace to 1280m³ and optimizing the technical-and-economic indexes. The blast furnace bottom adopted high density fire-clay bricks, water cooling device, pure copper cooling stave and Ukrainian large-scale cooling modules. 4 remodelled internal combustion hot stoves were installed. The ability of transmitting raw material was increased. The process control of blast furnace employed DCS system. Meanwhile, an intelligence automatic control system was used to optimizing the blast furnace operation. After the remodification,the equipment and automatic control of the blast furnace reach to national advanced level.
