white paperSuccessful Execution of Roll Cooling Strategies rev3. In today's hot rolling mill, realizing the promised longevity of high speed steel rolls depends on one's ability to develop successful roll cooling strategies that successfully manage heat transfer issues. Moreover, effective cooling in both hot and cold rolling mills. Get Price

Hot mills generally need more cooling and it is an advantage to have exit sprays as well as entry sprays. However, the exit sprays have more effect because the roll surface temperature is higher on the exit side. As a rule of thumb, the exit side cooling

Furthermore, when combined with in-line accelerated cooling, hot leveling and a shearing line, the Steckel process makes it possible to produce large quantities of discrete plates economically, achieving the tight geometrical tolerances and high yield typical of hot …

Inter Stand Cooling possibilities were determined by measurements and mathematical simulations in three different hot strip mills (2000 mm). The scheme of finishing mill with the cooling headers is shown in Figure 4. The ultimate possible temperature drop due to interstand cooling varies from 80°C - 65°C for the thick strip

CSI's Hot Strip Mill includes six finishing mills, which reduce the thickness of the transfer bar down to the gauge required by the customer or the next process. The rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, between 1500° to 1650°F, specified to reach certain mechanical properties.

type of pyrometer to measure the strip temperature stably during cooling on the hot run ta-ble of a hot strip mill and a control process for precise cooling of the strips using the pyrom-eter. The new strip cooling process was developed and put into commercial practice at Kashima Works and is being expanded to other mills of the company.
