With the advancement of technology in rolling mills, the size of rolling mills grew rapidly along with the size of the products being rolled. One example of this was at The Great Exhibition in London in 1851, where a plate 20 feet long, 3 1 ⁄ 2 feet wide, and 7/16 of an inch thick, and weighing 1,125 pounds, was exhibited by the Consett Iron ...
After World War I the company bought land at nearby Roundwood, and by 1920 a tenth open hearth furnace was added and new rolling capacity on 10-inch (250 mm), 12-inch (300 mm) and 18-inch (460 mm) rolling mills began production. In 1946 steel plate rolling ended.
The works began rolling double-headed rail in 90 feet (27 m) lengths in 1929, and 120 feet (37 m) lengths in 1937. [5] Output was c.130,000 tons steel ingots in 1920 and 1929; in 1937 reduced to 100 thousand tons. In 1936/37 the business made a 6.4% profit (c. £0.1 million on capital of c. £1.6 million). [9]
A tandem rolling mill is a rolling mill used to produce wire and sheet metal. It is composed of two or more close-coupled [clarification needed] stands, and uses tension between the stands as well as compressive force from work rolls [clarification needed] to reduce the thickness of steel. It was first patented by Richard Ford in 1766 in England.

The heart of the temper mill is the cold rolling mill stand which produces the temper pass. It will include electric powered drive motors and speed reduction gearing suited to the process desired. The design of the rolling mill can be a 2-high or 4-high (even 6-high in some cases). The mill stand can be work roll driven or back up roll driven.
