For the argon bottom bubbling technology,first use the similar principle to the production of water model in laboratory simulation model to determine the argon flow and other key parameters on the impact of technology,then identified the argon flow range of Cr20Ni35 and 4J43 alloy in argon bottom bubbling process.

Effect of 80 t Converter-Ladle Argon Stirring-Concasting Steelmaking Process on Gas and Inclusion Content in Steel Q235A;

Compared blowing nitriding to ladle with alloying nitriding, the blowing nitrogen to ladle is thought to be a economic and advisable method.

Mathematical model of argon blowing behaviors in ladle;

The principle and method to measure directly the main flow velocity of liquid steel ina 60 tons argon-stirred ladle by a probe(an immersed body)were introduced in the paper.
