MANUFACTURE OF TITANIUM CLAD STEEL PLATE AND TITANIUM CLAD STEEL PLATE

摘要

PURPOSE: To manufacture a titanium clad steel plate having excellent joining strength at a low cost. ;CONSTITUTION: In this manufacturing method of the titanium clad steel plate by the hot rolling, one or more passes of the rolling of the assembled slab for rolling are executed in the first hot rolling process with the draft of ≥15% at 950-1100°C, and one or more passes of the rolling with the draft of ≥5% at 90-600°C are executed in the second hot rolling process to manufacture the titanium clad steel plate. The slab may be left in the air down to the temperature of ≤900°C after the first hot rolling process, and rolled in the second hot rolling process. Thus, mass production of the titanium clad steel plate can be achieved by using the conventional hot rolling mill for the steel. Since the draft is large and the yield and the joining strength are improved, the titanium clad steel plate with excellent joining strength can be obtained at a low cost.;COPYRIGHT: (C)1996,JPO
