<p>PURPOSE:To reduce heat consumption and to improve the yield of rolling and the efficiency of a continuous casting method by covering the outside surfaces of an ingot with covering materials such as heat insulating materials, antioxidizing materials and the like in arbitrary places right after the pinch rolls of a continuous casting device. CONSTITUTION:The ingot 1 cast by a continuous casting method is drawn in an arrow direction by means of pinch rolls 2. The covering materials 3 formed on the outside surfaces of the ingot 1 are press stuck with press rolls 4. The covered ingot 1 is cut to standard lengths with a cutter 5 and the cut ingots are fed into a heating furnace while the ingots are heat insulated with the materials 3. Surface flaw detectors 6 are provided right after the rolls 2 and the ingot which is detected of surface flaws is ceased of covering and is fed into a conditioning stage for flaws. The other ingots are applied with the coverings and are subjected to high temp. charging, direct charging or direct rolling. Silica, alumina, magnesia, lime, etc. are molded or are used in the form of powder, slurry or liquid as the covering materials. A heating agent such as Al powder may be contained therewith.</p> |
