AI Technical Summary
In the existing technology of RH smelting of ultra-low carbon steel, the timing of temperature and oxygen measurement is not accurate enough, and multiple measurements of molten steel temperature and oxygen content are required. In addition, expensive mass spectrometers are required, which makes the operation complicated and costly.
The invention provides a method for intelligently determining the timing of temperature measurement and oxygen determination in the RH refining process of ultra-low carbon steel. The method automatically determines the temperature measurement and oxygen determination time at different smelting stages and realizes the automated temperature measurement and oxygen determination operation by using a temperature measurement and oxygen determination instrument, a control unit and a prompt unit.
The level of standardized on-site operations has been improved, and the accuracy of molten steel temperature and composition control has been enhanced, achieving a 98.5% breakthrough temperature compliance rate and a 99.2% internal control pass rate for molten steel carbon content.
