Problems solved by technology

The existing technology generally calculates the amount of wire feeding manually, manually inputs it on the HMI screen, and then manually controls the start and end of the wire feeding action. The disadvantage is that manual calculation and manual input may easily cause data input errors, and generally Control according to the upper limit requirements results in higher costs and requires more auxiliary time, which has a certain impact on the production rhythm

Abstract

The invention relates to an intelligent control system for a secondary feeding machine for a ladle refining furnace. The intelligent control system comprises an L2 parameter storage and maintenance module, an L2 data collection module, an L2 thread yield self-learning module, an L2 thread calculation module, an L1-L2 communication module and an L1 PLC control module. According to the invention, the technique of automatically calculating thread types and lengths is employed. On the basis of the initial composition and target composition requirements of molten steel, the needed thread types andlengths are calculated automatically, so that the error caused by manual calculation is avoided and thus the control precision is improved. Moreover, no manual computation is needed, so that the manual labor intensity is reduced.

Description

technical field [0001] The invention relates to a control system, in particular to an intelligent control system and control method for a second-stream wire feeder of a ladle refining furnace, and belongs to the technical field of ladle refining furnace control systems. Background technique [0002] The ladle refining process involves adding various wires (such as aluminum wires, calcium wires, etc.) to adjust the composition of molten steel to meet the target requirements. At the same time, when the oxygen content of molten steel is high, use aluminum wires to deoxidize and adjust the aluminum content of molten steel. In order to ensure the target requirements of molten steel composition, it is very important to accurately control the amount of wire feeding. Due to different batches of the same silk thread, there are certain differences in linear density and composition, and slight changes in equipment conditions will lead to changes in the effect of silk feeding. In order ...
