ON THE CONTROLLED CHARGING OF BLAST FURNACES

摘要

The demands technology of charging blast furnace can be met while fulfilling three prerequisites. Number one, the charging device must be capable of achieving a high degree of circular uniformity in distributing burden material and a flexible control of ore/coke rations along the furnace top radius. Number two: the charging device must be equipped with means to monitor the charging technology on-line. And number three - ACS must support the optimum distribution of ore/coke rations along the furnace radius, using feedback of furnace performance data. The above-said prerequisites have been partially put into effect and are still under development on blast furnace N° 2 at JSPL Steel plant of Jindal Corporation in India. This furnace is Equipped with the bell-less rotary charging unit (BRCU). Nowadays the installation of automatic system called "TOTEM Top Scan" for monitoring the charging process is under implementation.
