development of rolling mill - steel rolling mill machine

The development of the primary rolling mill has gone through three stages. By the early 1970s, the roll diameter of the mill has increased to 1500mm. Since 1959, China has designed and manufactured the blank opener. At present, 700mm, 750m, 850m and 1150M primary rolling mill have been made. Since 1980s, continuous casting technology has been developed greatly

rolling millproduction line: presentation on electric arc

The el ectric arc furnace is an electric furnace that uses high temperature produced by electrode arc to smelt ore and metal. When the arc is formed by gas discharge, the energy is concentrated and the temperature of the arc zone is above 3000 ℃. For smelting metals, EAF is more flexible than other steelmaking furnaces, which can effectively remove sulfur, phosphorus and other impurities
