MMK is upgrading three converters to increase productivity and improve blowing process efficiency. The focus of the order is on a new BOF (Basic Oxygen Furnace) converter model, which calculates the optimal composition of charge materials and process gases.
By upgrading three converters, PJSC Magnitogorsk Iron and Steel Works (MMK) in Russia intends to increase its productivity and make the blowing process more efficient. The order includes the purposeful modernization of the automation system for the three converters, in particular the expansion of the basic automation system to include our BOF process model. Furthermore, the three converters, numbers 1, 2, and 3, will be equipped with a bottom-stirring system for inert gases (nitrogen and argon). The objectives of the upgrade are high process stability and high flexibility with regard to the varying input volumes of pig iron and scrap, as well as a reliable process flow that saves both time and material.
