GENERAL ASPECTS OF ROLL COOLING FOR HOT COLD

As cold rolling of steel requires a lubricant in order to fulfil the lubrication role, oil is necessary. Hence, water-oil mixtures are used with a percentage of oil in water of approx. 5%. In most cases emulsions are the common coolants for cold rolling, where the oil and the water form a pseudosolution. There are stabile and meta- stabile -

60 YEARS OF ROLLING MILL TECHNOLOGY By Ford B. Cauffiel

At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills and blooming mills. Companies such as Mesta, United, Blaw-Knox, Lewis, Continental, and Bliss were attributed to building some of the largest rolling mills in the world before World War II. In fact, Mesta and United pioneered the rolling process to reduce very thick as

Rolling (metalworking) - Wikipedia

Tandem mills can be either of hot or cold rolling mill types. Defects. In hot rolling, if the temperature of the workpiece is not uniform the flow of the material will occur more in the warmer parts and less in the cooler. If the temperature difference is great enough cracking and tearing can occur. Flatness and shape. In a flat metal workpiece, the flatness is a descriptive attribute ...

Cold Rolling - process overview -

The cold rolling mill is usually fitted with thickness gauges that check the steel as it comes out of the rollers. Reversing mills are designed so that the steel can be reversed and pushed back through the rollers which are brought closer together each time until the desired thickness is achieved. Multi-stand mills have three to six pairs of rollers in a series, each pre-set to reduce the thickness by a certain
