A system for determining process parameters for the ladle refinement of steel includes a computer executing a number of software algorithms for determining one or more process parameters for various steel refinement process steps. In one embodiment, for example, the computer is configured to determine the total amount of flux additions to achieve a desired sulfur percentage as part of a steel desulfurization process. In another embodiment, the computer is configured to determine the total quantity of oxygen to be injected into the steel as part of a steel reoxidation process. In still another embodiment, the computer is configured to determine a melting temperature of inclusions within the refined steel, and to determine whether this melting temperature is within an acceptable range to successfully process the steel in a continuous steel strip casting apparatus/process, or whether the steel must be reworked to achieve an acceptable inclusion melting temperature.
A process for ladle refinement of steel for a steel strip casting process, the process comprising the steps of:
A method of determining melting temperature of inclusions within a batch of molten steel, the method comprising the steps of:
A system for determining melting temperature of inclusions within a batch of molten steel, the system comprising:
A method of determining a quantity of flux to be added to a batch of molten steel to reduce an initial sulfur content thereof to a desired sulfur content, the method comprising the steps of:
A system for determining a quantity of flux to be added to a batch of molten steel to reduce an initial sulfur content thereof to a desired sulfur content, the system comprising:
A method of determining a quantity of oxygen to be added to a batch of molten steel to increase an initial free oxygen content thereof to a desired free oxygen content, the method comprising the steps of:
A system for determining a quantity of oxygen to be added to a batch of molten steel to increase an initial free oxygen content thereof to a desired free oxygen content, the system comprising:
