Abstract

The invention discloses a mode-based converter steelmaking automatic control device and an application method of the automatic control device. The automatic control device comprises a converter body, an oxygen gun, a feeding device, a bottom blowing device, an oxygen gun control system, a bottom blowing control system, and a feeding control system, wherein the oxygen gun and the feeding device are arranged above the fire hole of the converter body; the bottom blowing device is arranged at the bottom of the converter body; the oxygen gun control system is used for controlling the oxygen gun to move vertically; the bottom blowing control system is used for controlling the variety and the flow of gases blown from the bottom blowing device; and the feeding control system is used for controlling the variety and the weight of auxiliary materials added by the feeding device. Automatic control on the converter steelmaking process can be achieved, and the mode-based converter steelmaking automatic control device has the beneficial effects of simplicity and convenience in operation, and low error rate.

Description

technical field [0001] The invention relates to a converter steelmaking method, in particular to a mode-based automatic control method for converter steelmaking. Background technique [0002] In converter steelmaking, oxygen is blown into a converter equipped with molten iron and scrap steel to carry out a violent oxidation reaction, to remove carbon and harmful impurities in molten iron, and to turn molten iron into molten steel. During the blowing process, the auxiliary raw materials are added from the silo to form slag, and the impurities are brought into the slag through the steel slag interface reaction, and the stirring gas such as nitrogen or argon is blown at the bottom to strengthen the stirring of the molten pool, which is conducive to the full progress of the chemical reaction . [0003] At present, in the process of converter steelmaking, the operator needs to often set the oxygen flow rate, bottom blowing gas flow rate, nitrogen and argon switching timing on th...
