Rolling Margin of Steel Test Procedure

Now, to test the rolling margin of steel, we need to get a cut-length of 1 meter of a specific diameter of steel. The length of the samples should be at least 0.5 m or 500 mm. For example, let us take the cut-length of 16 mm diameter TMT bar and weigh it. We get actual weight of the cut-length steel as 1.56 Kg.

Understanding Rolling Process in Long Product Rolling Mill

If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours.
