Goodyear Experience in Temperature Control of Mill Rolls

Doubling the gage of the mill increases the roll temperature 10° F., due to increased working of the batch. The same effect is obtained by increasing the size of the batch, up to the point of producing an idle bank. As small a change of ratio as from 1.11 to 1.17 will produce a rise of 10–12° F. in roll temperature.

Temperature monitoring of hot rolling mills Fluke

2021-8-29  Hot Rolling Mills. In metalworking, rolling is a metal forming process in which metal stock is preheated up to 1300°C (2400°F) and passed through rollers to reduce thickness. Hot rolling processes include pre-heating furnaces, scale breakers, slab scale, rough stand, finishing stand and cooling lines. Request more information. At a Glance
