Piercerolling Process Salzgitter Ag Geschichte

The pierce-rolling process, which was patented in 1886, made it possible for the first time to roll a thick-walled seamless hollow body from a solid steel billet.. To do this, the billet is heated to between 1200 and 1300 C and then positioned between two rolls arranged at an angle to each other and operating in the same direction, thus locking the billet into a kind of gear mechanism.
