Dec 08, 2015 The steel plant has several scale pits in operation. One of the smaller in-plant scale pits holds 25,000 gallons of water and has the highest concentration of scale. The scale is pumped away via a flume. The pumps in this scale pit need to be extremely reliable and handle large scale loads without clogging.
taining heavy scale particles, flows to a scale pit where these particles settle, the effluent then being repumped to the mill for roll cooling as in the plate mill. Surface oil also is skimmed from the scale pit and is pumped to tanks (Figure 4) for further concentration before removal. The steel from the roughing stand is reduced further in

Sep 08, 2017 The scale can pop off the surface, cracking the coating and allowing moisture to penetrate. This allows a galvanic reaction to occur which results in pitting corrosion (rust) to the base steel. Scale is a nuisance when the steel is to be processed. It
In steel production, hot milling and casting uses water at rates of between 100 cubic meters per hour and 10,000 cubic meters per hour, depending on the scale of the operation. As steel leaves the casting operations, cooling and cutting with water produces mill scale (iron oxides). Mill scale particles range from a few microns up to the size of a fist. They are also heavy and abrasive.
