1. When sintering type refining slag is applied to pipeline steel such as X70, the amount of 10-13kg /T steel can be added and decreased appropriately according to the pre-sulfur (pre-sulfur is less than 70PPm) and the slag thickness of ladle into LF furnace station;
2, electric furnace steel add this product about 6Kg/T (according to the LF slag to determine the amount of lime), in order to improve the basicity;
3, in each stage of refining should be fully paid attention to blowing fluorine mixing in the slag, uniform composition, uniform temperature and other aspects of the role;
4, should observe the slag situation at any time, according to the slag condition adjust the dosage of deoxygenation and refining synthetic slag amount;
5, on the continuous casting, should ensure that the pure stirring or calm time is not less than 5 minutes;
6. When added to the ladle for use, it can be put into the ladle according to its specific situation.
7, conditions can be combined with blowing argon stirring, so that the product and molten steel fully contact reaction.
8. The product can be made into balls for weighing.
