We used microscopes to detect imperfections and there were always problems. I also did the uniformity surveys of ovens which had to be within +/- 3° throughout furnace area you could fit a dump truck in.

Ya, the plate rolling mill I worked in had strict limits too. Time from furnace to rolling was critical. Mostly because of the metalurgy but also because of the extrordinary ability of titanium to lose heat. 40 seconds was fine, 41 was questionable, send it for analysis, 45 would break the mill.
In the Swansea rolling mill we had to open the door (not always easy as you will know, given the forced door design) discharge the load, rotate it 90 degrees, traverse from one of the 6 furnaces and stuff it into the rollers. 40 seconds. 3 tonnes. 2200 degrees.
