20.500.12556/DKUM-39031 ZAMENJAVA POGONA NA SREDNJI PROGI V VALJARNI REPLACEMENT OF THE ELECTRIC DRIVE OF THE MIDDLE LINE IN THE ROLLING MILL Diplomsko delo govori o zamenjavi glavnega pogona s pripadajočim napajanjem in regulacijo na srednji progi v valjarni. Delovanje obstoječega pogona je podrobno opisano z vsemi prednostmi, slabostmi ter željami, ki bi jih moral imeti novi pogon. Z upoštevanjem želja uporabnika sem izbral, predstavil in opisal tri različne možne rešitve zamenjave glavnega motorja, in sicer z asinhronskim, sinhronskim in enosmernim motorjem. Pri vseh treh rešitvah bi podjetje veliko pridobilo pri učinkovitosti in zanesljivosti proizvodnje linije, vendar je najbolj ekonomsko upravičena zamenjava motorja s sinhronskim motorjem. This paper speaks about the replacement of the main electric drive together with associated power and regulations on the middle track in the rolling mill. Operation of the existing electric drive is described in detail with all the advantages, disadvantages and desires which the new electric drive is expected to have. Considering the wishes of the user, I chose, presented and described three possible solutions of replacing the main motor, namely with the induction, synchronous and DC motor. Taking into account all these solutions, company would gain much in efficiency and reliability of production line. However, the most economically justifiable is the replacement of the main motor with the synchronous one. Valjarna pogon asinhronski motor sinhronski motor enosmerni motor. Rolling mill electric drive induction motor synchronous motor DC motor. true true false [A.
