Process

M.S. Scrap of predetermined composition is melted in Induction furnace and Liquid hot metal is transferred in pouring ladle

From pouring ladle the liquid metal Is transferred into ingot moulds. The ingot moulds are placed on the bottom plate at the correct position. Ingot moulds are C.I.Moulds placed with larger cross section at bottom. The central trumpet which receives the liquid metal is lined with bricks inside. General practice is to use three sets of bottom plates with moulds. Ingot moulds are cleaned from rust and dust from the inner surface with compressed air and suitable coating of graphite powder is given inside for easy removal ingot moulds. After the hot metal gets solidified, the ingot moulds are removed by crane. The ingots are then knocked out and transferred to cooling area for . Any surface defect if observed is removed by grinding, chipping etc. Ingots are batch marked of grade/heat number and stocked for dispatch. induction melting of steel uses pig iron and sponge iron as charge material in the project report.The most commonly used ingot mould sizes for ingot production are 3½”x4½”x54”.
