DEVELOPMENT OF NONFERROUS CLAD PLATE AND SHEET BY WARM ROLLING WITH DIFFERENT TEMPERATURE OF MATERIALS

Clad materials are more useful than uniform materials in many cases since they have characteristics of both materials. Aluminum is characterized by low density, high thermal conductivity and low electrical resistivity. When combined with carbon steel, stainless steel or titanium, aluminum clad plate and sheet are created. Basic studies were carried out on a mill model. First, aluminum clad steel plate was developed by the method of warm rolling where materials were heated to different temperatures and then bonding conditions were made clear. Aluminum plate was heated and layered on steel plate which was at room temperature, and finally rolled without welding. Second, stainless steel clad aluminum sheet was developed by warm rolling method where both materials were heated to the same temperature. Titanium clad aluminum sheet was treated in the same way as aluminum clad steel plate, and bonding conditions were made clear. Last, wide plate and sheet were manufactured in the mill and characteristics of these products were made clear.
