Evaluation of friction in the hot rolling of steel bars by

2004517 · Coefficients of friction in the range 0.35–0.40 have been evaluated from the forward slip measurements. The rolling speed did not exceed 0.2 m/s and measurements were made in the temperature range 1000–1150°C. No clear influence of temperature on friction could be observed. The stability measurements show similar results.

Hot Rolled vs Cold Rolled Steel: Overview and Differences

The hot-rolling process involves pressing the molten steel at high temperatures of over 926° Celsius (1700 degrees Fahrenheit). Such high temperatures are essential because steel ideally recrystallizes between 750 degrees to 1,300 degrees Fahrenheit, allowing easier forming and reshaping. ...
