Micropurity of steel manufactured in vacuum induction furnaces
 Hořínek, Jakub ; Myška, Martin (referee) ; Záděra, Antonín (advisor)
During the production of steel, a certain proportion of non-metallic inclusions always arises, which significantly affects its final properties. The theoretical part of this thesis focuses on the effects of these impurities on the properties of steel and on ways to reduce their total content in steel. In the experimental part, the effect of vacuum melting, with casting in air, on the final micropurity of stainless steel was investigated. The results showed that the vacuum method was very effective as there was a significant reduction of the oxide inclusions content and oxygen content in the steel. Then, a part of the material from the first melting was remelted and the effect of repeated vacuum remelting of the material with casting in vacuum was investigated. The analysis showed a significant reduction in nitrogen content but the oxygen content remained almost the same.
