20.500.12556/DKUM-81777 Konstruiranje naprave za površinsko hlajenje valjev diplomsko delo Design of a surface cooling device for rolls Toplotna obdelava je ključni del v postopku izdelave kvalitetnega izdelka, v tem primeru valja. Med postopkom izdelek večkrat segrevamo in ohlajamo, da s tem zmanjšamo zaostale napetosti v valju in zagotovimo ustrezno trdoto. Diplomsko delo zajema konstruiranje naprave, katere naloga je ta, da med procesom toplotne obdelave po ciklu segrevanja opravlja proces prislinega hlajenja. Proces prisilnega hlajenja, ki bo potekal na napravi je sledeč. Segret valj, ki se bo horizontalno položil na napravo se mora med delovanjem vrteti, posledično enakomerno ohlajati po celotni površini, škaja, ki nastane med ohlajevanjem se mora avtomatsko odstraniti, zagotoviti se mora ustrezna zaščita pred hlajenjem na delih valja kjer je to zahtevano in hkrati se mora zagotoviti tudi, da se valj med celotnim procesom ne bo pomikal v smeri svoje horizontalne osi. Heat treatment is a key part in the process of creating a quality product, in our case a roll. During the heat treatment procedure the product is heated and cooled multiple times. With this we reduce the residual stresses in the roll and ensure the adequate strength that is required. The diploma work contains the design process of a device of which the task is to perform the cycle of forced cooling after the heating cycle in the procedure of heat treatment. The forced cooling cycle which will take place on the device is as follows. The hot roll which is placed horizontally on the device has to spin throughout the whole cycle and it has to be cooled evenly over the entire surface area of the roll. The device has to remove the scale which is formed during cooling and adequate protection against cooling must be provided on the required parts of the roll. Finally, it has to be ensured that the roll does not move in the direction of it's horizontall axis during the whole process. toplotna obdelava prisilno hlajenje zaostale napetosti ustrezna trdota enakomerno hlajenje segrevanje. heat treatment forced cooling residual stresses adequate strenght even cooling heating. true true false [D.
