roll down to the required thickness of strip.
<p>For best results, roll the strip in as few passes as you can handle.
+The results aren’t accurate for broad, thin strips.
+Width-to-thickness ratios of up to 6:1 are known to be good; ratios of
+12:1 or more don't work: strips don’t get as wide as predicted by
+our model. We need to collect more data and construct a better model to
+handle this case properly.
