[0022] Example
[0023] Desulfurization station takes molten iron samples and sends them to the laboratory for testing as soon as possible, and the test components of the molten iron samples from the laboratory are transferred to the second stage of the converter through the second stage of the laboratory in time. The converter level 2 sends the blowing time, oxygen blowing flow rate and oxygen lance position to the converter level 1 PLC according to the molten iron silicon content and the oxygen lance position and flow control correspondence table before the start of the converter. After the blowing starts, the converter level PLC controls the oxygen blowing flow and the oxygen lance position according to the blowing time progress.
[0024] Among them, the molten iron silicon content and the oxygen lance position and flow control correspondence table are:
