摘要： PURPOSE:To enlarge a rolling reduction of a titanium material and to improve an efficiency of a rolling mill by conveying the titanium material in the state of covering its upper and lower surfaces with steel plates heated to the rolling temperature of the titanium material and performing a hot rolling by removing the steel plates just before the rolling. CONSTITUTION:The upper and lower surfaces of the titanium material/(or titanium base alloy material) travelling on roller tables 2 are covered with the steel plates 3 possessed of temperatures about 1100-950 deg.C. The titanium material 1 whose upper and lower surfaces are held between the heated steel plates 3 is transfered to the rolling mill 4, and immediately before arriving at the rolling mill 4, only the steel plate 3 on the upper surface is removed and the lower steel plate 3 is allowed to pass through the rolling mill 4 as it is thus only the titanium material 1 is subjected to rolling reduction by the rolling mill 4. In this way, because the titanium material can be rolled while maintaining on a proper temperature, the rolling reduction per one pass is enlarged and the problems of the shapes such as a waving camber are improved.

摘要： PURPOSE:To considerably decrease waving camber of a titanium material, etc., during hot rolling by rolling the titanium or titanium alloy material while the material is held inclined at a required angle with the line of the rolling direction, then inclining the material in the direction opposite from the above- mentioned direction in the next pass, rolling the same and alternately repeating such rollings. CONSTITUTION:The above-mentioned titanium material 1 is rolled while the center line in the longitudinal direction of the material 1 is inclined an angle theta1 with the rolling direction X-X line and is passed between rolling rolls 2 at the time of hot rolling the material 1. About 15 deg. is preferable for the above- mentioned angle theta1. In practice, the material is inclined to the width at which the engagement of the rolls 2 is possible. The material is inclined at an angle theta2 in the direction opposite from the above-mentioned theta1 relative to the rolling direction X-X line and is rolled. The above-mentioned theta1 and theta2 may not always be the same. The waving camber during the hot rolling is considerably decreased and the rolling reduction per pass is largely taken by executing the rolling while repeating the above-mentioned method, by which the rolling efficiency is improved.

摘要： PURPOSE:To decrease the crop loss at the front and rear ends of slab and to improve yield by forging a titanium cast ingot and working the ingot to an approximately I-shaped slab then reheating the slab and subjecting the slab to drawing and edging by rolling. CONSTITUTION:The titanium cast ingot A obtd. by vacuum arc melting, etc. is subjected to cross forging in a beta phase temp. region in a forging stage B to form the approximately I-shaped slab S1 having the width H1 at the front and rear ends larger than the width H2 in the central part. The slab is then subjected to a drawing and edging pass at a high rolling reduction of about >=80m/m in the direction of the slab end broader than the central part by rolling under the temp. conditions similar to the temp. conditions of the forging stage in a blooming stage C. Rolling rolls execute edging by restraining the free surface of the rolls having calibers by which a slab product S2 is obtd.
