scrap diameter rolling mills

The paper describes an innovative technique for producing balls which are used as grinding media in ball mills. With this method, balls are formed from heads of scrap railway rails. The proposed two-stage technique is based on cross wedge rolling. First, a rail head is formed into a cylindrical bar with a diameter of 52 mm.

Cold rolling mill is a new type of steel bar cold rolling equipment. The machine can process hot-rolled wire rods and circles with a diameter of 6.5 mm to 12 mm into cold-rolled ribbed bars with a finished specification diameter of 5 mm to 12 mm. The cold-rolled ribbed steel bar rolled by cold rolling mill is an updated product of cold drawn ...

Benchtop Rolling Mills With hardened rollers and precision-machined gears, these rolling mills stand up to heavy use. They're often used to compress sheets to an uncommon gauge size, convert scrap metal into sheets or wire, or create different thicknesses in a single piece of metal without welding multiple pieces together.

After certain steel mill's high-speed rod line was gone into operation, adopting cross-sectional area was the square billet of 150 * 150mm or 160 * 160mm, and the bright wire material of producing Φ 5.0～22mm is coiled the screw-thread steel wire rod (that is valve snail) of (that is round steel) and Φ 6.0～16mm.Its maximum mill speed can reach 110m/s.Yet, milling train steel-fastening ...
