METHOD OF MANUFACTURING SHEET BY PACK ROLLING

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a sheet by pack rolling by which the wide thin materials of an alloy such as a heat resistant alloy and titanium alloy whose hot work is difficult are especially manufactured into products having small thickness deviation by hot rolling. SOLUTION: In the method for manufacturing sheets by which a pack rolled stock is formed by covering one or plural pieces of planar core materials with a spacer material and a cover material and the sheet is manufactured from the core material by rolling this pack rolled stock, by this manufacturing method of the sheet by pack rolling, draft is defined as >=15% about passes whose reduction ratio is >=3 to the initial thickness of the pack rolled stock.
