[PDF] PROCESS IMPROVEMENTS ON ROD MILLS | Semantic Scholar

In a modem high-speed rolling mill, where steel temperature exceeds 1,000°C (1,800°F), production speeds surpass 100 m/s (20,000 fpm) and coils can be 10 km (6 miles) long, it is impossible to visually inspect the entire surface of any coil for defects. This is especially true when the defect in question is a seam—a tightly rolled discontinuity in the rod surface that is typically ...

Failures of Rolling Bearings in Bar and Rod Mill

Bar and rod mills can usually be found in the steel-rolling process at a steelmaking plant. Pre-heated steel billets are rolled into the mill in order to produce channels, bars, rail beams, etc. The rolling stock is then forced into the grip of rolls, rotating in opposite directions. The two rolls, which are supported by rolling bearings, and a ...
