A furnace chamber is formed in the converter so that magnesium can be used to process the cast iron melt. The size and shape of the furnace wall components of the converter have a decisive influence on the efficiency of processing the cast iron melt in the converter and the accuracy of obtaining the remaining magnesium content.
