Can-rolling of beryllium ingots
Aspects of hot-rolling cast-beryllium billets canned in 304 stainless steel are examined. Emphasis is placed on the development of the proper rolling schedule to completely convert the columnar cast structure to a uniform equiaxed one. Also emphasized are curling difficulties found in rolling this two-metal composite. The curling is found to depend chiefly on friction between ths billet and work rolls. Lubrication and roll surface finish are found to be the key variables which in turn control friction. Curling is best prevented by having a higher friction coefficient on the bottom billet surface than on the top during rolling. (auth)
