The history of rolling rolls. Renaissance

Rolling is a classic way of plastic deformation of metals. The schematic diagram, and then the drawings of the rolling mill for lead, were developed by Leonardo da Vinci. In the Renaissance it was also established that the main property of the material of rolling rolls is its smoothness and the ability to withstand more strain loads without flaking the particles of the material.

XIX century

As an alternative to roll steels, cast iron was considered, the smelting of which was already mastered in those years. The advantage of cast iron was that the amount of carbon as the main carbide-forming material in it is greater than in steel alloys, so the hardness of cast iron rolls was higher. However, it was unprofitable to conduct the rolling with the initial shock application of the load (the first stand), since the cast-iron rolls were rapidly dyed.

Optimization of the composition of roll steels

• An increase in the percentage of carbon contributed to an increase in the strength of the rolls, especially in the range 0.8… 1.2%;
• Purification of the melt from harmful non-metallic inclusions occurs when manganese is introduced into the melt. Manganese provides the spheroidization of carbides, and increases the uniformity of particle distribution by volume. The maximum permissible content of manganese in modern grades of roll steels is 1.5… 2.0%;
• Similarly to manganese, it has been established that silicon acts, but its percentage in the roll steel should not exceed 1.2… 1.5%;
• The fine grain structure and uniform strength along the section of the ingot, from which the rolls are subsequently produced, ensures the presence of nickel, chromium and molybdenum in the steel.
