Study on adaptive parameter internal mode control method for argon-oxygen refining ferrochrome alloy
Source abstract
Abstract
To enhance the rate of argon–oxygen refining of ferroalloys, this article is based on the physical and chemical reactions of the smelting process as well as the actual smelting data. A mechanistic model of the rate of change of oxygen supply and carbon content in the smelting process and the temperature of the reaction fluid in the furnace is established. An expert internal model control framework with furnace temperature and carbon content as output and oxygen supply rate as input is constructed. An adaptive parameter adjustment mechanism is added to the control framework by combining data on the maximum gas supply rate and temperature threshold of the stage in the actual production process. The method improves smelting speed and smelting accuracy compared to the general method. It is also able to adjust the furnace temperature according to the actual smelting situation. The actual smelting was carried out according to this method, the improved method reduced the smelting time by 12.79% compared to the general method, and the furnace temperature was controlled below 1950 K.
