DE2933483A1 - Inspection jig for billet guide track in continuous casting plant - for measuring dimensional width of track prior to casting - Google Patents

Abstract

The jig is lowered by a chain into the guide and support roll track to measure the width of the track which determines the width of the cast billet or slab. The jig consists of a frame fitted on each side with pairs of centering rolls; and at least one roll on each side of the jig can be reversibly driven. Between each pair of rolls is a measuring sensor feeding signals either by cable or radio to display or recording appts. The jig frame also carries work cylinders, which push anvils against the rolls in the billet guide track to locate the jig.

Description

The invention relates to a measuring and testing device

for continuous casting molds and guide roller tracks with opposite one another Roller tracks, in particular for support frames, support tracks and pull-out machines from Continuous casting plants essentially consisting of a chain or the like and a transport device which can be guided to the respective measuring point and which can be adjusted in width Holding frame with centering rollers mounted on both sides and in pairs, of which at least one is reversibly drivable on each side and in the middle between the rollers and perpendicular to their axes with measuring sensors, which are connected via cables or wirelessly in connection with a display or writing output of measured values stand.

A dear-like measuring and testing device is described in DE-PS 26 39 240 disclosed. With this known device, the clear dimensions of continuous casting molds, the opening width of the rollers and their runout on guide roller conveyors are measured and Checked the roles.

The invention is based on the object of providing a device of the initially described called type so that that of the known measuring and testing device available measurement results supplemented by the distance between successive pairs of rollers can be.

According to the invention, this object is achieved by what is specified in the main claim Features solved.

The further development of the subject matter of the invention is based on the subclaim emerged.

The advantage achieved by the invention is that now with a single measuring and testing device next to those that have already been determined Measured values also the distance between successive pairs of rollers can be detected.

Another advantage is that of the construction according to the invention resulting inevitable rotation from roller pair to roller pair.

An embodiment of the invention is shown in the drawing.

FIG. 1 shows an outlined mold and a mold Arched roller conveyor of a continuous caster with retracted measuring and testing device in side view, Figure 2 is a plan view of the device according to Figure 1.

According to Figure 1, the measuring device is located in the guide roller conveyor an arc continuous caster 10.

The measuring device consists of a chain 12 and guide elements 24,24 'formed guide and feed device can be guided to the respective measuring point width-adjustable holding frame 1 with mounted on both sides and in pairs Centering rollers 2, 2 'and centrally between these rollers and perpendicular to their axes arranged sensors 3, which via cable 11 or wirelessly with an indicating or writing measured value output (not shown). the Guide elements 24, 24 'are connected to the clamping cylinders 20, 20', with both the elements 24, 24 ′ and the clamping cylinder 20 are rotatable and relative via the elongated hole 23 are arranged movably to the holding frame 1. The clamping cylinders 20 are on both sides provided with holding prisms 25 and 25 '.

The guide elements 24,24 'are on a centering roller side of the Holding frame 1 arranged.

They extend over at least three roles of the roller conveyor to be tested and lean on the two outer ones, keeping the middle roll free Roll off.

When the measuring device is introduced into an arch system, there are the guide elements 24,24 'on the roller conveyor with the larger radius of curvature. Of the centering rollers 2 resting on the rollers of the guideway, at least One each reversibly drivable to check the castors for runout and ease of movement to be able to.

When using the measuring device according to the invention, the device via the Zll-controlling system, e.g. an arch system on the mold cover plate set over the mold opening. Then the measuring part of the device lowered into the mold.

After the centering rollers have been pressed against the mold walls, the Measuring sensor used. The measured values can now be read on a digital display and / or recorded by a scribe. This measuring process can take place at any Make the mold wall are repeated.

After the mold has been measured, the entire measuring device is centered deposited over the mold opening. Then the measuring device is up to first pair of rollers lowered until the sensors are already extended 3 of the device indicate the position of the first pair of rollers. Upon reaching this Position, the lowering of the measuring device is stopped and the centering rollers 2.2 ' by means of the device 5 for adjusting the width of the holding frame 1 for accurate Determination of the mouth width approached to the rollers. According to concerns about the roles will these alternately with the aid of the drivable centering rollers 2 of the measuring device rotated so that from the changes in the measured values the roller runout of each individual Role can be determined and recorded.

At the same time, the load on the drive motors is measured the centering rollers 2 checked the ease of movement of the guide track rollers.

To measure the distance "X" between pairs of rollers, an the pair of rollers 6,6 ', the clamping cylinders 20 are extended and sit down with their holding prisms 25 and 25 'on the rollers 6 and 6' in the plane 21,22. The holding frame is now 1 moved together and moved into its new measuring position for the pair of rollers 7,7 '.

After reaching this position, the distance is "X" and thus the distance of the roller pairs measurable. With the help of the width adjustment 5, the frame 1 is with its centering rollers 2 are approached to the rollers 7 and 7 'and then the clamping cylinder 20 moved together and the way "X" to their new position the level 21 'and 22' moved.
