PURPOSE:To obtain Fe/Al clad steel plate excellent in workability by heating and press-fixing each material through electric heating to the optimum temperature. CONSTITUTION:Steel blanks 1, 3 are provided with two electric rollers 11, 14 and a steel blank 2 is provided with one electric roll. Power sources 21, 23 are connected between the respective electric rolls and current is made to flow between them, the aluminum plate is heated at an ordinary temperature -450 deg.C and the steel plate is heated at 600-910 deg.C and the clad steel is sent between pressing rolls and press-fixed at a draft below 30%. In this way, the Fe/Al clad steel plate suitable to workability and different uses can be manufactured. |
