20.500.12556/DKUM-10735 SNOVANJE NOVIH TIPOV VALJEV ZA VALJANJE PLOČEVINE PLANNING NEW TYPE OF ROLLS FOR ROLLING THIN PLATES V diplomskem delu je opisan potek projekta trdnostne kontrole valja za vroče valjanje pločevine. Obravnavali in analizirali smo celoten postopek od priprave konstrukcije valja skozi njegovo izdelavo do odpreme h kupcu na testno vgradnjo. V nalogi smo podrobneje preiskali mehanske lastnosti jedra in nove delovne plasti (plašč) valja, kar je osnova za kasnejše preiskave. Večji poudarek pa smo posvetili ugotavljanju oziroma meritvam zaostalih napetosti v delovni površini valja ter protiobrabnim lastnostim opisane površine. Opisane lastnosti bistveno vplivajo na nosilnost valja med obratovanjem in s tem na želeno življenjsko dobo. The diploma work presents the course of the project which deals with a control of hardness of the rolls for hot rolling of thin plates. It has been discussed and analyzed the entire method from preparation of roll construction during the entire manufacturing to a departure to a customer on a test operation. In the diploma it has been dealt with mechanical characteristics of a core and a new working layer of the roll in greater detail, which is the basis for further research. Greater emphasis has been placed on findings and measurements of delay strain in a working layer of the roll and its antiabrasive characteristics. Represented attributes essentially affect on endurance capacity of the roll during operation and influence on the working expectancy of the roll.
