Abstract

Diplomska naloga preučuje ravnost debele pločevine jekla AISI 304 po vročem valjanju. Delo zajema tehnološko pot izdelave debele pločevine od valjalnega stroja pa vse do skladiščenja pri sobni temperaturi. Posebej sem preučil delovanje vročega ravnalnika, njegovo delovanje in vpliv na ravnost plošč. Vsi preizkusi so potekali na industrijski ravni v vroči valjarni podjetja SIJ Acroni. V grobem pride do neravnosti po vročem valjanju zaradi dveh vzrokov. Zaradi mehanskih vplivov med vročim valjanjem in termičnih vplivov po vročem valjanju pa vse do sobne temperature v skladišču. V diplomski nalogi sem opisal tudi različne vrste napak, ki povzročajo neravnost na debeli pločevini in postopke ravnanja za vsak tip napake. Meritve smo izvajali na nerjavnim jeklu AISI 304. Cilj je preveriti ravnost jekla AISI 304 pri različnih deležih plastifikacije debele pločevine in upogiba zgornje kasete na vročem ravnalniku.

Secondary title: levelling of AISI 304 steel heavy plate after hot rolling
Secondary abstract: The diploma work examines the flatness of thick AISI 304 steel sheets after hot rolling. The work covers the path of the plate from the hot rolling machine all the way to warehouse, where it reaches room temperature. I specifically studied the hot plate leveler, its operation, and its effect on a flattens of a plate. All tests were performed at the industrial level in the hot rolling department of SIJ Acroni. Roughly, unevenness occurs after hot rolling for two reasons. One is due to mechanical properties during hot rolling and thermal factors from hot rolling to warehouse, where it reaches room temperature. In my work I also described the different types of errors that cause unevenness on the thick metal sheets and the handling procedures for each type of error. Measurements were performed on AISI 304 stainless steel. The goal was to check the flatness of AISI 304 steel at different plastification fraction of thick sheet metal and deformation of the hot leveler.
