Improving the process flowsheet manufacture of bulb-flats profiles production in Ukraine

Abstract

As a result of research of the manufacturing technology and quality big section symmetric bulb-flats profiles from continuous casing billets is shown, that the level, achieved in Ukraine, in a condition to ensure parameters of service properties of roll according to the requirements of the conducting world registers of shipping. For the first time made in Ukraine a trial and skilled party bulb-flats profiles from continuous casting billet in comparison with traditional technology (casting in ingots + subsequent manufacture of billet) are characterized by the greater uniformity of mechanical properties, high viscosity and plasticity.
