摘要： A thin rolled steel plate, and method and apparatus for producing it is disclosed. The thin rolled steel plate is formed with a drum shape in cross-section with a thickness ratio of a central portion to the edge portions of at least 1.1. The rolled steel plate is rolled having a concave drum shape during the rough rolling step and/or the first half of the hot finishing rolling step so as to achieve the desired drum shape. The plate is subsequently rolled in the second half of the hot finishing rolling step and the cold finishing rolling step by concave drum shaped rollers which reduce its thickness while not altering its drum shape.

摘要： In producing a titanium strip using a continuous hot strip mill, the invention discloses a method of producing a titanium hot coil by a continuous hot rolling system characterized by the steps of heating a titanium slab to 700.degree.-950.degree. C. inside a heating furnace, then performing the hot rolling, and winding the hot rolled strip in a coil form while the strip is kept at a temperature of not lower than 450.degree. C. under a condition that at the time of taking up the leading portion of the resulting titanium hot rolled strip after hot rolling, its trailing portion is being caught by the final stand roll of a finishing mill of the continuous hot strip mill.
