Sep 12, 2007 The material-handling system was designed with a lance-pusher rather than a typical skewed-roll drive Fig. 8.

Since steel is relatively soft at typical hardening temperatures, the force exerted by the skewed roll imparts distortion into the pipe.Free consultation 40 years of industry experience providing one-stop solution
