Abstract

An excellent arithmetic for flow rate control - expert and alterable parameter PID control arithmetic has been developed by combining theory with practice to realize optimal control for bottom blowing flow rate. The practical application of 30 ~ 120 t top and bottom combined blown converter indicated that the expert and alterable parameter PID control technique had nice control performance i. e. smooth and quick to control bottom blowing flow rate curves

precisely modify flow rate

effectively prevent bottom lance blocking and obviously increase economic benefit.
