Process Optimization And Control For RH Degassing Unit

With the continuous development of RH vacuum degassing technology, it has been becoming more and more important. The main task of RH is: degassing deoxidation decarburization desulfurization, dephosphor exactly chemical tuning steel homogenisation increase steel purity temperature tuningIt improve the quality of liquid steel, increase yield and reduce energy consumption to adopt process computer and mathematical model in RH vacuum refining process.This dissertation states the principles of RH degassing, the degassing model, the deoxidation model, the decarburisation model, the alloying model, and the temperature calculation model. Expatiates in detail on the realization of these models.
