Компенсация поверхностных дефектов при толстолистовой прокатке

Modeling of transition of sites of lateral faces of slabs on contact surface is executed. It is established that the difference of temperatures of the top and bottom sides of a piece before layout of width promotes adverse shift of cracks deep into to colder side. Actions for blocking of movement of cracks are developed for improvement of quality of rolled metal products.
