Abstract Single snorkel vacuum refining equipment is a new style refining equipment. One hundred twenty seven heats experiments on decarburization were carried out by 80t single snorkel vacuum refining equipment. The results indicate that single snorkel vacuum refining equipment can obtain better decarburization effect. The minimum content of carbon is 10×10-6. The experiment process of single snorkel vacuum refining equipment is introduced in this text, and analyzing different inflation factors for results of decarburization. The factors contain flow ration of ladle bottom blowing, thickness of slag in the ladle, free space height of ladle, treating time, temperature and component of steel liquid. The reasonable technology parameters were suggested.
