Analysis and Process Optimization on Hydrogen Content by Electroslag Remelting of Steel 316H for Nuclear Power by Li　Dejun, Ge　Chunyu, Zhao　Liang, Li　Haiqiang, Ma　Qiang, Liu　Lei

“…In order to find out hydrogen content change law in ESR ingot during electroslag remelting， and on the basis of each process optimize to improve the electric slag ingot hydrogen content qualified rate ， nuclear power steel 316H is taken as the research object to study processing parameters such as melting speed， filling ratio， slag ingredients， amount of slag added， initial hydrogen of electrode and partial pressure of water vapor by using a 15 ton electroslag furnace in this paper.The results show that hydrogen addition is different in each stage of electroslag remelting，the hydrogen content in ESR ingot is proportional to the square root of water pressure in the air. The CaO can promote hydrogen increase and MgO can prevent hydrogen increase in the slag ingredients. …”
