Riser design plays an important role in the casting of the components. The component taken for casting is the "column". This column is used to support various parts of blast furnace. Increasing the casting yield by optimizing the volume of riser for the casting of column such that the shrinkage defect and the hot spots is eliminated is the main objective of this project. Geometric modeling of column is done in catia v5r20 through which volume and surface area of the column for different sections was obtained and section with higher modulus is calculated. Formulation for riser using cylindrical neck is done and has been given to the constrained optimization technique in MATLAB R2017a and the optimum dimensions of riser is obtained which has been compared with the ongoing manufacturing of column in industry and 18.5 % reduction of riser volume is obtained which increases casting yield.
