Jan 01, 2007 Hot strip finishing mill is initially set up with rolling conditions such as roll speed, roll gap, and cooling pattern obtained by a set-up model. To improve the accuracy of initial roll speed setting for a 7stand finishing mill, an equation for predicting forward slip and a compensation method for initial roll speed setting were proposed ...
Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.
Dec 03, 2015 The rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, between 820 deg C to 900 deg C, so as to achieve certain mechanical properties in the hot rolled strip. The finishing mills roll the transfer bar in tandem, meaning each bar is rolled through all the finishing stands at once.
