20.500.12556/DKUM-61747 Postopki kovanja jekla Methods of forging steel Cilj diplomske naloge je predstaviti postopke preoblikovanja jekla, izzive pri kovanju, preoblikovalne stroje primerne za kovanje ter njihovo izbiro pri kovanju. Pri preoblikovanju jekla ločimo prosto in utopno kovanje, pri čemer prosto delimo na ročno in strojno kovanje. Zelo pomembna je tudi pravilna izbira peči, saj če dosežemo pravilno temperaturo v peči, na surovcih nastane manj okujin. V diplomski nalogi pa sem navedel tudi nekaj strojev, ki so primerni za kovanje, opisal kaj je pomembno pri njihovi izbiri ter naredil izračun za izbiro primernega stroja. V diplomi sem želel raziskati, ali je pravilna izbira postopka kovanja pomembna za kakovost izdelka, čas izdelave in njegovo ceno. Omejitve, ki sem jih pričakoval pa so povezane z dimenzijo in ceno končnega izdelka. The following work presents processes of steel forming, challenges when forging steel, forming machines suitable for forging and which choice of machine is most suitable for forging. We can separate steel forming to free forging and drop forging. Free forging can be divided to hand forging and machine forging. The correct choice of furnaces is also very important. We must reach correct temperature in the furnace for raw steel to melt with less scalings. In diploma I mentioned some machines that are suitable for forging, described what is important when choosing it and did the calculation needed for selection of most suitable machine. I wanted to investigate whether the correct choice of forging process is important for product quality, preparation time and price. Restrictions that I expected are associated with the dimension and cost of final product.
