Embodiment Construction

[0012] The taper measuring device of the circular copper tube crystallizer of the present invention is composed of two major systems of mechanical structure and data processing; it can be used for on-site measurement and special measurement room measurement. Among them, the detection instrument is the main body in the mechanical structure, see figure 1 , 2 As shown, it includes three major components: a detection body 1, a guide cover 2, and a feed push rod 3. The detection body 1 is supported in the inner cavity of the circular copper tube 5 by two fixed support rods 8 and one elastic support rod 9 (elastic support point), which is responsible for movement and detection in the inner cavity of the circular copper tube 5 . Between the two fixed support rods 8, the fixed support rods 8 and the elastic support rods 9 are arranged at equal angles. According to the rule that three points form a surface, they constitute a stable detection volume. In order to increase the stabilit...

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...
