distribution of bottom nozzle with 4 hole symmetry
2 hole symmetry and 2 hole non- symmetry and blowing location d/D = 0. 1 - 0. 9 (d- diameter of concentric circles of located nozzle ; D- diameter of converter bath) on bath mixing time has been studied by 10 : 1 water modelling. Results showed that the stirring effect for 4 hole symmetry bottom blowing with d/D = 0. 3 and flow rate 0. 70 m

/h was optimum
the stirring effect for 2 hole symmetry bottom blowing with 0. 60 ~ 0. 70 m

/h and d/D = 0. 3 ~ 0. 5 was optimum
and that for 2 hole non-symmetry was respectively 0. 65 m
