20.500.12556/DKUM-22677 Prenos profila DIN 1570 na novo linijo valjanja Transfer of profile bar DIN 1570 to new rolling line Podjetje Štore Steel se ukvarja z valjanjem jekla. Do sedaj se je jeklo valjalo na stari valjarski progi 550, sedaj se valjanje prestavlja na novo konti progo. Valjanje na konti progi je hitrejše, kvalitetnejše in bolj avtomatizirano, s tem pa tudi kompleksnejše in težje nadzorovano. Valjanje specialnih profilov z rebrom je zaradi nesimetrične oblike še zahtevnejše. Namen diplomskega dela je simulirati valjanje specialnega profila DIN 1570 na konti progi s programom Deform. Z računalniško simulacijo po metodi končnih elementov je določena sprememba oblike valjanca med valjanjem. Numerični rezultati so primerjani z dopustnimi odstopanji, ki so dani s standardom profila. Štore Steel company deals with steel rolling. Until now, steel was rolled on an old mill named 550, but now, it is being moved to new continuous mill. Rolling on the continuous mill is faster, produces higher quality and is more automated, but also more complex and harder to control. Rolling special profiles with a rib is even more complex because of their asymmetric shape. The purpose of this diploma is to simulate the rolling of a special profile DIN 1570 on the continuous mill, with the program Deform. The shape changing of workpiece during the rolling is defined by a computer simulation using the finite element method. Numerical results are compared with the acceptable deviations, which are given by standard of the profile.
