Accusteel Ltd.

http://www.accusteel-Systems.com/

The control of the main technological parameters, temperature and chemical composition of the melt steel in the EAF and BOF steelmaking is performed by the certified instruments. For temperature control of the melt it’s using submersible thermocouple or “bomb”-thermocouple. For melt chemistry control it’s taking test sample and doing express analyze in the interferometer. And also it’s using the computer systems which are calculating the carbon percentage in the melt by temperature of thermocouple measurement. Analyze of results of these equipment is shown that the melt temperature and melt chemistry are determined with poor accuracy. For example, the determined average temperature at 255 measurements is 1622 ° C and according the normal distribution law the measure of inaccuracy is ± 34 ° C. The total inaccuracy consists of the sum of the determined inaccuracy and the systematic inaccuracy of instrument ± 10 ° C, so the total is ± 44 ° C. The situation is similar in chemistry analyze of the melt. Therefore more detailed analysis of the data is required. As a result of the correlation analysis of the data it was established that for all used certified measuring complexes the correlation coefficient is within the range 0.08 - 0.72, which is indicating low reliability of the received information. The low reliability necessitates to make melting with superheating of the melt of 80 - 100°С. The reason for this data mismatch is the locality of the determination of temperatures and chemistry in the high-temperature inhomogeneous melt. Accusteel Acoustic Control System is an alternative for the existing certified computer systems. Testing of the Accusteel system was made together with analyzing of data from the existing systems. It is proved that the Accusteel system is determining the mass-average temperature, chemistry and behavior of the liquid phase of the melt in real time and has high reliability with the correlation coefficient of 0.93 - 0.99. The Accusteel system allows controlling the slag level during the heat in real time. Control of thermal and slag adjustment parameters allows to optimize the process with increasing up to 30% of the unit's capacity, up to 20% energy saving, up to 10% increase of yield, reduction of deoxidants and ferroalloys using, elimination of emissions, and also improve of conditions at the workplace of steelmakers. High reliability of the Accusteel system information can provide possibility for full automation of BOF and EAF production.
