Spillage Control Method in the Production Process of Argon Oxygen Smelting Low-Carbon Ferrochrome

Abstract:

Taking the process of Argon oxygen smelting low-carbon ferrochrome as the research object using the multi-rules fuzzy control, the signal of sound intensity is divided into different segments. According to the different segments,control the oxygen flow rate, nitrogen flow rate, the height of Oxygen lance and the addition amount of foam inhibitor, complete the design of the fuzzy controller, then carries on the simulation under MATLAB.The simulation results show that in different segments, the time of the system achieve stability is different, but when the sound intensity stability in 30-50 normal range and the system adjustment time in 3-5 min is a relatively stable system and able to suppress spillage occurs quickly.
