Parametry ovlivňující vnitřní kvalitu mikrolegovaných plynule litých bram

Abstract

Bachelor thesis is focused on technological parameters affecting the internal quality of microalloyed CC slabs during the continuous casting. First, the characterization of micro-alloyed steel is made with a view to their chemical composition, distribution, industrial use and a basic description of production technology. In the following section, the various parameters affecting the internal quality of microalloyed continuously cast slabs are desribed. These parameters include for example: tundish metallurgy, chemical composition of steel, casting speed, temperature of the casting, cooling method, etc. The influence of defined parameters that affect the internal quality CC slabs is summarized from the results in the conclusion.
