A method for collecting mill scale from a hot rolling mill is provided. The hot rolling mill includes a flume. The method includes transporting mill scale particles in wastewater, retrieving the wastewater from a flume of the hot rolling mill and separating the mill scale particles from the wastewater using a separator. A hot rolling mill and a method for retrofitting a hot rolling mill are ...

roll force and torque in the hot rolling process. As an improvement, Poliak, Shim, Kim, and Choo (1998) examined a proposed linear regression model to predict the roll force in hot plate rolling. Lee and Lee (2002) proposed a longterm learning method using neural network to improve the accuracy of rollingforce prediction in hot rolling mill ...

with direct contact force sensor Measuring roll has high reliable magnetoelastic force sensor in roller shaft every 90 deg. There are four snapshots of the flatness profile for every revolution. From Magnetoelastic force sensor, Shapemeter System can measure force distribution with width direction and then evaluate shape profile at online.

Iron making and steel making areas often have an abundance of large belt conveyors, critical ultralow speed machines with limited rotation, critical large EOT cranes and large volume turbo blowers coupled with >2300 ºF hot blast air, molten liquid iron, red hot slabs, often carbon monoxide risks and of course, rolling mills.

HOT ROLLING MILLS. In a hot rolling mill process, the steel gets heated at extremely high temperature, which is generally above 1100°C. BLH Nobel can provide sensors and complete measurement systems that are highly durable and withstand the extremely harsh environment in .
