Embodiment Construction

[0066] in Figure 1A with 1B A measuring device 1 for automatically identifying the position of the gate of a metallurgical vessel with a measuring grid 5 that works in a non-contact manner is shown in FIG. Figure 1A Shows a front view, Figure 1B A top view is shown. Gate position refers to at least two-dimensional position description of the gate, such as the description of the position of the longitudinal axis of the gate. The measuring device 1 is movably constituted by a multi-axis multi-function manipulator via the support 4, so that the position along the longitudinal axis of the gate can be determined. In this regard, the measuring device 1 has a non-contact measuring grid 5 which discriminately discriminates the gate position in two lateral directions. The measuring grid 5 itself is composed of two groups of measuring rays 5, wherein the first group is arranged in the first transverse direction x and the second group is arranged in the second transverse direction y. In...

Abstract

The method of automatic layer recognition of spouts (10) of a metallurgical vessel such as a converter, a pan (9) or a casting distributor by a measuring device (1) with a contactless working measuring grid (3), comprises: a) positioning the measuring device (1) vertically below the spouts (10) so that the spouts (10) cut neither the measuring device (1) nor affect the measuring grid (3) and a measuring curtain (8); b) moving the measuring device (1) vertically basically to a first position; and c) contactlessly detecting an actual position of the spouts (10) through analyzing measurement data of the measuring grid (3) for partial dispersion of the measuring device (1), wherein the measurement data at least comprise a plurality of x-measurement values that are assigned to a first transverse direction (X) of the measuring device and y-measurement values that are assigned to a second transverse direction (Y) of the measuring device. Furthermore a measurement value corresponds with one measuring ray (5) of the measuring grid (3), thereby determining the actual positions of the spouts (10) in the first transverse direction (X) of the measuring device by means of the x-measurement value at a first position, and determining the actual positions of the spouts (10) in the second transverse direction (Y) by means of the y-measurement value, wherein the second transverse direction of the spouts (10) is vertical to the first transverse direction (X) of the spouts.

Description

Technical field [0001] The invention relates to a measuring device and method for automatically identifying the position of a metallurgical vessel, especially a gate of a converter, a steel drum or a tundish, by means of a measuring device, the measuring device having a non-contact working measuring grid or a contact working The measuring curtain. Background technique [0002] Those skilled in the field of foundry science or metallurgy have known various methods for identifying the position of the gate of a metallurgical vessel: [0003] According to one method, an optical stereo camera is used for this, in which the gate position is determined by the position of a measuring plate placed on or connected to the gate. The premise of this method is: [0004] -The measuring plate should be accurately placed on the gate, so that the gate position can be inferred from the position of the measuring plate, [0005] -There is enough space on the gate to place the measuring board, [0006] -Th...
