Abstract
The production technology of super clean steel at Baosteel is introduced Under the conditions of the existing technologies and installed equipment,the total content of phosphorus,sulphur,total oxygen,nitrogen and hydrogen in super clean steel amounts to 80×10 -6 The mass production technologies of IF steel,pipe line steel are introduced The control of carbon,nitrogen,total oxygen as well as inclusions of IF steel,and the control of phosphorus,sulphur of pipe line steel are discussed
