The Cold Drawing Process for Steel Bars and Wire

The Cold Drawing Process for Steel Bars and Wire. Raw StockHot rolled steel bar or rod coils are used as raw material. Because the hot rolled products are produced at elevated temperatures (1700 2200 Deg. F. i.e. hot rolling), they generally have a rough and scaled surface and may also exhibit variations in section and size.

Tube drawing principles The FABRICATOR

The rod drawing process draws the tube over a hardened steel rod, or mandrel, that passes through the die with the tube. The typical die angle for rod drawing is 36 degrees; the bearing length is short. This process reduces the OD, ID, and wall thickness. A secondary operation called reeling expands the diameter slightly so the rod can be

Hot Rolled vs Cold Rolled Steel Metal Casting Blog

Cold rolled steel Cold worked steels are typically harder and stronger than standard hot rolled steels. Cold rolled steel is essentially hot rolled steel that has been through further processing. Once hot rolled steel has cooled, it is then re rolled at room temperature to achieve more exact dimensions and better surface qualities.
