Abstract
A new estimation procedure for estimating the influence of rapid strengthening on the strain resistance is proposed using a 6061 aluminum alloy (AD33, 1330) as an example. To implement this procedure, it is suggested to mathematically process the data of a system for monitoring a hot rolling mill. Attention is paid to the fact that the roll force in each pass increases with the rolling speed. On the basis of the determined strain resistance at a known roll force, it is possible to plot strain resistance as a function of the rolling speed. It has been revealed that the results of data processing are reliable for roll passes from 6 to 12, which is confirmed by the results of dispersion analysis. The obtained results have been compared with the published laboratory data, and they are found to agree with each other. The results obtained can be applied for everyday operation of rolling-mill shops.
