Abstract

PURPOSE: To enhance the performance of controlling the final carbon content and the final temperature of a molten steel, by a method wherein a synthetic control is conducted by combining a static control to set a program based on charing conditions and blowing-out conditions with a dynamic control utilizing process signals obtained during refining.
CONSTITUTION: Based on an input from a condition setter 26 and a previous analogous blow refining pattern, a reference claculator 27 calculates the continuous variation amount of the target amount of oxygen accumulated in slag and feeds it to a blow refining controller 25 so as to determine and adjust the height of the lance, the amount of oxygen blown in and the amounts of auxiliary materials charged. Then, the blow refining is started, the data from a calculator 28 for the amount of oxygen accumulated in slag are inputted into the controller 25, and the controller 25 corrects reference values for the height of the lance and the like. Immediately before the blow refining is completed, an apparatus for a sublance 4 is operated, a correction operation command device 30 estimates the final molten steel temperature and the final carbon content on the basis of the actually measured values of molten steel temperature and carbon content as well as the information of the amount of oxygen accumulated in slag which is fed from the calculators 27, 28, and the height of the lance and the like are corrected toward the target values through the controller 25.
