Us5660070a Cold Rolling Mill With Tension Bridle
tension bridles for a cold rolling reducing mill are provided. the reducing mill reduces the thickness of a metal strip passing through the reducing mill. the tension bridles create tension on the metal strip between the bridle and the first reducing stand to receive the metal strip and between the final reducing stand and the exit bridle so that a greater reduction can be made in the roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill sees instantaneously unless some damping system such as a surge hopper is used.sms demag hot strip mills the drum-type shear installed between the roughing and finishing mills of a hot strip mill crops the trans-fer bar at its head and tail. In special applications, the drum-type shear also serves to divide transfer bars and finished plates. based on the experience gained from more than drum-type shears built so far,apr 29, 2016 sendzimir rolling mill technology and machine design. over years of experience in hot and cold rolling mills for carbon, stainless steel, and non-ferrous rolling mills. our precision cold rolling mills have name brand recognition worldwide for gauge accuracy, flatness of strip shape, and ultrathin gauge. before 90% of the worlds stainless
