Implementation of Lance Control in Top-Blown Copper Smelting Process Based on DCS

Abstract:

Top-blown furnace is known to be effectively adopted in copper smelting. This paper elaborates lance control strategies in top-blown smelting process based on the real project named KUNPENG COPPER SMELTER in China. We implement lance control by using several schemes, such as auto lower, auto raise, normal raise and emergency raise; meanwhile, we propose a method of auto creep control to stabilize tip pressure of lance. Moreover, the configuration of the smelting control system based on Emerson DeltaV is introduced. The result reported clearly shows that the lance rises and falls automatically according to specific conditions, as well as the lance tip pressure is stable and creep movement is precise and responsible.
