From ancient times, a person learned to extract iron and make instruments of labor and other objects important at that time from it. The transition from the Bronze Age to the century of iron according to archaeological excavations occurred about three millennia ago. It was from this moment that the development of ferrous metallurgy began. Later, people guessed to heat a piece of cast iron in the horn along with a piece of ordinary iron ore. So there was a huge leap in the history of metallurgy – steel was obtained. But the scale of its production was still negligible. By the middle of the fourteenth century, this problem was solved – domain stoves were created and industrial volumes of production of steel and cast iron were established. But from the same they did everything: weapons, and wheels and other utensils. Many industrialists were puzzled by this problem, since the material was not as universal as we would like. By the end of the eighteenth century, this problem was solved, and with it the era of “pure” steel was completed. Simply put, steel began to allocate. Learned and change the properties of cast iron, regulating the carbon content with it. And in almost the same form the production of ferrous metals has reached this day. The modern metallurgical plant is equipped with electric stoves with high -precision sensors, a large set of rolling equipment and the chemical department for competent alloy. All this allows you to produce high -quality products and work with a minimal impact on the ecology.
