Essay

The work deals with solving the applied problem of lengthening the cycle of trouble-proof work of blast furnace casings at the expense of domestic high-strength rolling usage. The task was solved by creating temperature-deformative regimes of plate rolling from steel 10Г2ФБЮ to form in polygonal austenite structure heterogeneous nucleation of ferrite. It leads to the formation of highly dispersed ferrite-perlite structure that keeps a high level of power, plasticity and heat-resistance of plate, while being exploited under the conditions of elevated temperatures.
