NEW PROGRESS OF APPLICATION OFMATHEMATICALMODEL OF CONVERTER

The dynamic control of sublance is based upon the static control of converter, which is the basic control model of converter computer system. With static models (including end control, oxygen feeding control, slag making control, bottom blowing control) and dynamic models (for decarburization speed, molten steel heating and quantity of mixed cooling agent) used in converter steel-making the pressure tolerance at mouth can be decreased, gas recovery increased.
