Conicity measurement mechanism for circular copper pipe crystallizer

Abstract

The invention discloses a conicity measuring device of a crystallizer with a circular copper tube, which comprises an object to be detected that is supported by four fixed supporting points and an elastic supporting point in an inner chamber of the circular copper tube as well as a displacement sensor that is arranged on the object to be detected and at one side of an elastic supporting rod; when the object to be detected moves inside the circular copper tube, the four fixed supporting points are contacted with the surface of the inner chamber of the circular copper tube all the time, thus ensuring a measuring axial line to be positioned on a normal line of inner and outer arcs all the time. The conicity measuring device can conveniently, reliably and precisely detect each shape index of an inner chamber of the crystallizer with the circular copper tube, and is applicable to the size precision and geometrical shape detection of the inner chamber of the crystallizer with the circular copper tube.

Description

technical field [0001] The invention relates to the field of metallurgical continuous casting, in particular to a circular copper tube crystallizer taper measuring device, which is used for checking and measuring the dimensional accuracy and geometric shape of the circular copper tube crystallizer cavity. Background technique [0002] Because the shape of the inner cavity of the mold copper tube is related to the output and quality of the continuous casting slab, manufacturers have always attached great importance to this. At present, a good solution has been found for square and rectangular copper tube crystallizers. Due to the special shape of the inner cavity of circular copper tube crystallizers, in addition to ensuring that the measurement axis is always on the normal line of the inner and outer arcs, it is also necessary to It is very difficult to ensure that the measuring device cannot be displaced in the circumferential direction, and the measurement process must alw...

At present, a good solution has been found for square and rectangular copper tube crystallizers. Due to the particularity of the shape of the inner cavity of the circular copper tube crystallizer, in addition to ensuring that the measurement axis is always on the normal line of the inner and outer arcs, it is also necessary to It is very difficult to ensure that the measuring device cannot be displaced in the circumferential direction, and the measurement process must always be carried out along the established generatrix (or outer arc reference line), so there has been no suitable detection method
