  central jet
It has been found that the droplet generation rate improves significantly due to the presence of the central jet.

This in turn produces an intermixing zone between the central jet and recirculating region further downstream from the valve, which contributes to the high-stress zone measured.

The speed of the decay of the jet stream discharged from the five-orifice lance nozzle has been measared. The result shows that the speed of the decay of the central and the peripheral jet's velocity isn't identical which is caused by the difference of the jet's surrounding condition. When the diameter of the central orifice(C.O)is equal to the diamefer of the peripheral orifice(P.O), the velocity of the central jet is twice as fast as the velocity of the peripheral jet, in the condition of the common...

The speed of the decay of the jet stream discharged from the five-orifice lance nozzle has been measared. The result shows that the speed of the decay of the central and the peripheral jet's velocity isn't identical which is caused by the difference of the jet's surrounding condition. When the diameter of the central orifice(C.O)is equal to the diamefer of the peripheral orifice(P.O), the velocity of the central jet is twice as fast as the velocity of the peripheral jet, in the condition of the common lance height. In order to make fuller use of these jets to agitate effectively and homogeneously the molten bath, the velocity of the central jet should be equal to, or slightly greater than, that of the peripheral one at the surface of the molfen bath. In order that this object can be obtained, the design of the five-orifice nozzle ought to make the area of C. O(Ac)less than that of each P. 0(Ap). According to the measured result, Ac/ Ap should be equal to 0.6-0.8.

测定了五孔喷头射流速度的衰减速率。测定结果表明,由于中孔射流和边孔射流的边界条件不同,因而它们的速度衰减速率不同。当中孔和边孔的直径相等时,在正常的枪位下,射流速度中孔比边孔大一倍。为了充分地利用五孔喷头的射流对熔池的有效和均匀的搅拌作用,要求作用于熔池面时,中孔射流的速度应等于或略大于边孔射流的速度,为此设计五孔喷头时应使中孔面积(A_中)小于每个边孔面积(A_边)。测定结果得出A_中/A_边应为0.6~0.8。
