Abstract
PURPOSE: To save pattern-draw process and produce the clad-steel at high efficiency by pouring molten steel for internal member in the material for external part of a case whose inside surface is formed with undulations and which has no draft and rolling the steel after allowing the molten steel to harden.
CONSTITUTION: A case 2 which is disposed with lump-form protrusions 1 on both longer and shorter sides of the inside peripheral surface and has no draft is formed by using the material for the external part of the clad steel. Borofluoride being an antioxidant is coated on the inside of the case 2 and molten steel or the like for the material for the internal part is poured and is allowed to metallurgically bond and set. Next, the case is loaded into a soaking pit, after which it is rolled to arbitrary shapes through blooming, hot rolling, etc. whereby the clad steel is obtained. This product is covered at its edge parts and is highly corrosion resistant. This method reduces the production time from casting up to product.
