PURPOSE:To enable the omission of the conventional bar stock manufacture and rough forming process and to improve the productivity by cold-rolling a deformed cross sectional ingot, executing the heat treatment and further, applying a skin pass-rolling. CONSTITUTION:Molten metal in a melting furnace for a continuous casting apparatus is poured into a mold and then solidified, and the ingot are drawn out from drawing-out mechanism to form the deformed cross sectional inoat. This deformed cross sectional ingot 8 is cold-rolled and thereafter, the heat treatment is executed and further, by applying the skin pass rolling, the deformed cross sectional shape is manufactured. By this method, the productivity is improved and this manufacturing method can be kept up with any kind of the shape and the product having good surface characteristic can be obtd. |
