DEFORMATION BEHAVIOUR OF SECTIONS FROM X15CRNISI20-12 HEAT RESISTING STEEL IN ROLLING OF SPECIAL SECTIONS

Popis výsledku v původním jazyce

The purpose of this paper is to give a comparison of the behaviour of heat-resistant austenitic stainless steel X15CrNiSi20-12 and the ordinary S355J0 steel grade during rolling of a special-purpose section for door hinges from 80 x 80 mm stock in caliber rolls under normal service conditions of VÚHŽ special section rolling plant. The X15CrNiSi20-12 steel grade possesses low thermal conductivity and high thermal expansion capacity. The latter leads, together with higher flow stress, to more pronounced spreading of this material. This paper deals with the entire rolling procedure of 61949-type section. The initial position of the rolled stock in caliber rolls plays an important role. Key parameters monitored in the process of plant rolling include the shape of the product, spreading, surface temperatures, surface quality, metallographic structure and torques. Comparisons are made in the first and second roll calibers which are open and do not constrain the spreading. The cross-section s
