temperature gas will have a reduced cooling effect three different approaches have been illustrated for varying the volume fraction of solid between the respective sprays 16 and 17 using the apparatus 10 of fig1 these approaches can be used individually or in combination as desired to achieve the desired volume fractions of solid in the respective sprays 16 and 17 referring now to fig2 additional alternative embodiments for varying the volume fractions of solid between the respective sprays 16 and 17 will be described the apparatus 10 39 in fig2 is similar to the apparatus 10 shown in fig1 except that the direction of movement of the collecting member 18 is opposite the most significant change in the apparatus of 10 39 versus 10 is the use of two separate tundishes 24 and 24 39 one for each respective nozzle 28 and 28 39 in the apparatus 10 39 the use of two tundishes 24 and 24 39 allows the temperature of the molten metal supply 11 in the first tundish 24 to be varied from the temperature of the molten metal supply 11 39 in the tundish 24 39 if desired further the use of two tundishes 24 and 24 39 allows the respective distance of travel of the spray 17 to be different from the distance traveled by the spray 16 since two tundishes 24 and 24 39 are employed it is necessary to have two pin valves 26 and 26 39 controlled by.
