Abstract: The thermodynamic and kinetic analysis of increasing nitrogen and nitrogen discharge was done in the molten steel converter process.Combined with a large number of production practice,the influence of combined blown converter system,raw materials adding and collocation,converting process control,discharge control,the steel deoxidation alloying system as well as the throat opening differential pressure to the steel liquid nitrogen were discussed.The relative improvement measures were given.

Key words: technology of low nitrogen steel, blowing converter, denitrification, increasing nitrogen
