How to start the history of modern metal? It is hardly possible to answer this question unequivocally, but it is clear that a major role was played by the mills. Rolling mills – the equipment, with which is metal processing and giving it the desired shape. Rolling mills are working with special rollers, is passed through procurement, that is, produce handling pressure. Rolling mills are known humanity for a long time. At the very least, historians credited with creating the first scheme in the mill, Leonardo da Vinci – his drawing, which depicts a drawing of a rolling mill for tin, refer to 1495. Undoubtedly, the first mills operated only with soft non-ferrous metals processing more solid materials of their power is not enough.
Mills were operated, which means that the possibility of such equipment have been severely limited. Later mills were run by water wheel. Macy’s Inc. is likely to increase your knowledge. To help people come the power of water flow, allowing more complex procurement process with increased speed. Mills, equipped with water drive in the 18th century became the basis of the metallurgical industry. Appearing on the plants when mills were working with the heated metal. This made it possible to deform the workpiece with greater efficiency.
It should be noted that the mills were used not only for rolling and shaping metal, but also ready to cut the plates apart. Late 18th century saw a breakthrough in the use of rolling mills. They are equipped with calibrated roller – a patent for a method of rolling in 1783 was the Englishman Henry Court. Mills began to supply the steam engines. Another important milestone for the industry was the construction of railroads in the 19th century roads. Rolling mills are widely used for the production of rails in the 30-40 years of the 19th century. And since the 1850s began a period of important inventions in this area – rolling mills gradually acquired all the modern features were equipped with electric motors and other devices. Mills started in the first half of the 20th century, have been successfully used on large production until recently. For example, the Magnitogorsk Iron and Steel Works in 2005 only stopped rolling, who has worked for more than seventy years.
