HOT ROLLING PRACTICE – An Attempted Recollection

1. Introduction. It had be concluded so far that in hot rolling, increase in height of roll grooves which was a function of its expansion, caused by the process parameters, resulted in increase in thickness of rolled stock, which affected the mechanical properties of the rolled samples such as ultimate tensile strength, yield strength, bendability, modulus of elasticity, % reduction in area ...

Sep 12, 2007· Rolled Throughput Yield (RTY) Process 1 had a daily yield of 84% (84/100) while process 2 had a daily yield of 75% (82/110) and finally process 3 had a daily yield of 91% (126/138). So, to calculate RTY we simply multiply these yields together giving us a composite yield for the day.

The Hot Rolling Process - California Steel Industries

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

Definition of Rolled Throughput Yield (RTY): The probability that a single unit can pass through a series of process steps free of defects. Next we will turn our attention to a Rolled Throughput Yield example. If you will remember, the First Time Yield calculation we did (FTY) considered only what went into a process step and what went out.
