Influence of complex modification on gas content in shipbuilding steel

Abstract
Behavior of gases at the stages of production of high-strength vessel steel made with REM complex material and standard technology of steel modification by ferrocalcium has been investigated. It has been shown that the nitrogen content in steel increases regardless of which of the tested modifying treatment methods was used, from liquid castings to sheet metal rolling.
Oxygen content regardless of the modifying method increases in liquid metal including casting, after which it decreases significantly in slab and sheets. Modification of high-strength vessel steel by complex alloys with REM allows to reduce the hydrogen content in the metal.
