Process Studies Covering Hot Shearing Concept of Billet Separation. Volume II.
Abstract
The hot shearing and hot flame cutting concepts of billet separation for use in projectile forging applications were investigated during this project. The hot parting concept of billet separation involves heating 20 to 24 foot lengths of billet stock to forging temperature, hot shearing to required mult length after which the hot sheared mult moves directly to the forging press. Using this concept of billet separation, heating to forging temperature, parting to mult length and forging can be accomplished as a completely integrated, synchronized and automatic operation. Hot shearing studies were conducted on the 105 mm M1 and 155 mm M107 projectiles. Hot shearing was determined to be a completely satisfactory method of billet separation for projectile manufacture. Benefits which can be achieved from use of hot sheared mults are derived from reduced material handling, reduced material waste, reduced operating cost and improved projectile cavity surface finish. Hot flame cutting was determined to not be a successful process for parting of mults for projectile manufacture. Slag and molten metal caused problems in subsequent forging operation. (Author)
