The rolling oil is pumped from the clean tank into the mill stand where flow rates may be 14,000 l/min or more. In the mill stand the several thousand litres of rolling oil serve to cool the stock and rolls, lubricate the roller bearings and remove contamination. Primary filtration stage After passing through the mill stand, the

The L:S ratio of each sample is determined by test or by calculation. Each sample is violently agitated and the settling tests started. From the first 0.05 ft. settled in the tests, are calculated the settling rates corresponding to the feed horizons of continuous-settling tanks. These may be termed "the settling rates of feed."

Accurate prediction of the rolling force is critical to assuring the quality of the final product in steel manufacturing. Exit thickness of plate for each pass is calculated from roll gap, mill spring, and predicted roll force. Ideal pass scheduling is dependent on a precise prediction of the roll force in each pass. This paper will introduce a concept that allows obtaining the material model ...

Water (scale) pit in steel rolling mill? | Yahoo Answers. 1/3/2010· the first pit is called the scale pit because the water also collects the free scale off the steel. this scale has to be collected and dealt to, usually settling in the pit. the working height of the pit must be below the bottom of the HSM, so water and scale can be washed / flow into the pit, this means that the working ...
