Vliv válcovací teploty na vznik povrchových trhlin při válcování nástrojové oceli 19 569

Abstract

This thesis deals with finding the effect of rolling temperature alloy steel 19 569 on the formation of surface cracks. The first part is theoretical and deals with the rolling mill at which the experiment took place as well as an overview of the production and use of tool steels. The practical part is dedicated to the production technology and the experiments conducted at two levels of the rolling temperature. The part of this work is the final processing and comparing of the data obtained during the rolling process and the possibility of their use in subsequent production of tool steel 19 569.
