NOUFERROUS METALLURGICAL EQUIPMENT

Taking the research on the flow control of DelaV treatment process with the new algorithm of temperature and pressure compensation as an example, the oxygen-enriched flow is controlled at 3540.73~3651.37Nm3/h in the molten pool manufacturing process based on the new algorithm of temperature and pressure compensation, and at 5456.83~5577.27Nm3/h in the material addition and normal production process. All of them meet the requirements of process indexes, which completely solves the problem of inaccurate control of process oxygen-enriched flow caused by not considering temperature and pressure compensation in traditional current signal processing algorithm. It effectively improves the control accuracy of flammable and explosive gas medium in slag treatment process, realizes accurate batching and slag type control in melting furnace and fuming furnace, and has wide application value in many aspects such as accurate measurement of enterprise equipment and on-site safety.
