974,947. Rolling. SCHLOEMANN A.G. Feb. 2, 1962 [Feb. 3, 1961; May 23, 1961], No. 4180/62. Heading B3M. Round material, such as wire, is rolled from square billets in exclusively oval passes 13 having adjustable roll gaps 15, the material being under tension during rolling. Consecutive stands are horizontal or alternatively horizontal and vertical with interstand twisting guides. The use of oval passes is said to obviate the formation of cracks and surface defects in the material. |
