BAR MILL AND WIRE ROD MILL TOOLING, Bar Mill & Wire Rod Mills are continuous production lines with capacities of few thousand tons to a couple of million tons/annum. Each tool/consumable product used in the mill has to be of very high quality as a small breakdown costs hundred of tons production loss. Being used in hot application and at very high speeds, tools must withstand high temperatures & must have high degree of wear resistance and toughness.

Commonly used raw material grades | Bar Mill And Wire Rod Mill Tooling

Guide Box Rolls- H13 is most common grade for the initial stands where temperatures are very high. For intermediate & finishing stands, D2 is mostly used.

Pinch Rolls- In this application, due to the high speeds, wear resistance is most important. D2 is mostly used. Powder metallurgy rolls are also used for very long life. Hot Shear Blades- Because of high heat, H13 is the best suited material. Special 8% Cr tool steel is used for shearing higher diameter bars.

Cold Shear Blades- H13 being a tough grade, it work well in cold shearing up to 20 mm bars. For higher diameters, nickel based special tool steels are used.

Copper/Aluminum Wire Rod Mill Rolls- Due to extremely high temperatures & Copper/Aluminum being very soft, the rolls material becomes very critical. Commonly used grade is H13. DeeTee has developed a special tool steel grade which gives much higher wear & adhesion resistance at such high temperature compared to H13.
