Rigorous control of the temperature of the molten metal is necessary to insure a billet which is sound and free from porosity. The metal is being poured therough a cone known as a runner box, which is guided into place over the center of the mold by the operator at the lower left. The furnace operator at the right is handling a control which tilts the furnace and permits the metal to run into the vertical mold.
