Abstract

Description

FIG. 1 is a front view of a flow rate adjusting plate for a rotary nozzle type molten metal pouring unit showing my new design;

FIG. 2 is a left side view thereof;

FIG. 3 is a right side view thereof;

FIG. 4 is a rear view thereof;

FIG. 5 is a top view thereof;

FIG. 6 is a bottom view thereof; and,

FIG. 7 is a cross-sectional view taken along line VII--VII of FIG. 5.

The characteristic feature of my design is the octagonal body shape wherein one side of the octagon is of curvilinear form and merges into adjacent linear sides of the hexagon to form a parabola and wherein a circular hole is provided which is essentially coaxial with the curvilinear side, the hole being generally aligned with the axes at which the parabola merges with the sides which bracket the aforenoted hole, the hole being spaced from the parabola by distance no less than the hole's diameter.
