Abstract:V Termoelektrarni Trbovlje za proizvodnjo električne energije kot energent uporabljamo rjavi premog, ki ga meljemo v ventilatorskih mlinih. Rotor mlina je premera 2600 mm in ima na obodu nameščenih 10 do 12 udarnih plošč. Njihova obraba predstavlja velike stroške tekočega kot tudi remontnega vzdrževanja. V nalogi sem predstavil materiale udarnih plošč, ki so se uporabljali v preteklosti. Uvajajo se novi materiali za udarne plošče z navarom iz varilne žice. Uporabljenih oz. predstavljenih je več različnih materialov varilne žice za navarjanje. V praksi se uporabljajo trije do štirje materiali, ki so se izkazali za uporabne. V nalogi želim prikazati namen uporabe ustreznih navarov na udarnih ploščah mlinov, oziroma koliko se posledično s takim načinom vzdrževanja zmanjšajo stroški menjave rotorjev zaradi podaljšanja trajnosti dobe trajanja.

Title:Possibilities for increasing durability of rotor blades in coal mills using hard facing
Abstract:To generate electricity, in TET, we use brown coal milled with fan mills as an energy source. The rotor of the mill is 2600 mm in diameter and has 10 to 12 cladded plates installed at its periphery. Their wear deamands a high amount of recurring costs as well as the refit maintenance. In thesis, I have presented materials of cladded plates, which were used in the past. New materials for cladded plates with a welding wire are being introduced. Different kinds of materials for surfacing a welding wire are used and presented. In practice, three or four materials that have proven to be useful, are being used. In the thesis, I want to outline the appropriate use of welds on the cladded plates of mills and prove how much do costs of changing the rotors due to their extended life expectancy with this kind of maintenance reduce.
Keywords:cladded plate, wear resistance, hardness, impact toughness, microstructure, abrasion
