A gage, for determining the taper angle of the inner faces of the end walls of a continuous casting mold, includes a pair of rigidly connected, spaced apart, elongated, wall contact strips having parallel straight edges for engaging the wall for substantially its full height. A center, measuring strip is arranged between the wall contact strips and is pivotally connected to them at their lower ends. The measuring strip is pivoted by a manually operable screw that connects its upper end to the upper end of a wall contact strip. A level indicator mounted upon the top of the measuring strip indicates when that strip is vertical. A distance indicator gage mounted on the strips measures the amount of pivotal movement of the measuring strip until it becomes vertical. The taper gage is suspended in a mold and the wall contact strip straight edges are pressed against a mold end wall. Then the operator manipulates the screw to pivot the measuring strip until the level indicates that it is vertical. At that point, he reads the distance measuring indicator which may be calibrated to directly read the wall taper. |

DETAILED DESCRIPTION FIG.
1 schematically illustrates a typical continuous casting mold 10.
The mold is formed of broad or side walls 11 having copper liners 12 on their interior faces.
Between the broad walls are positioned the narrow end walls 13 which are also covered with interior copper liners 14.
The interface between the copper liners and the mold walls are provided with cooling channels through which cooling water is circulated to remove the heat of the molten metal.
However, these are not illustrated in the drawings as they are not pertinent to the invention herein.
The end walls 13 have mounting and positioning support rods which hold them between the broad walls.
Then the broad walls clamp against the end walls.
FIG.
2 illustrates schematically the slope or taper of the end wall inner copper faces, with the angle of slope being designated by the letter "a".
The actual slope or taper is very slight, as for example, a 16th of an inch horizontal offset difference between the upper end of the mold face and the lower end.
The slope may be measured in thousandths of an inch horizontal offset of the upper end of the mold, wall face from the vertical plane, passing through to the lower edge of the mold wall face.
The taper gage, as shown in FIGS.
5 and 6, includes a pair of elongated, flat, narrow, wall contact strips 17 and 18 having straight edges 19 for positioning upon the inner copper face of the end wall of the mold.
A measuring or pivot or center strip 20 is positioned between the two wall contact strips 17 and 18.
Preferably, the strips are made of lightweight material, such as magnesium, and may be provided with a series of holes along their lengths in order to lighten them still further.
These holes are not illustrated.
The two wall contact strips are rigidly fastened together by means of a lower U-shaped connector 22, an upper U-shaped connector 23, a pair of U-shaped handle connectors 24 and an upper block 25, all welded to the respective strips.
A U-shaped manually grasping handle 26 is welded to the connectors 24 (see FIG
