Description

The invention relates to a slide lock of the type specified in the preamble of claims 1 and 2, respectively.

In a known slide lock of this type (System FLOCON) the metal frames are fireproof Plates and the parts of the pressure maintenance device on a hydraulic anhcbbr-cn assembly trolley assembled and then by extending the hydraulic assembly trolley * against the ground of a container raised. If the slide closure assembled in this way is in its intended I-agc is arranged around the outlet opening of the container, it is by means of the hydraulically liftable assembly carriage pressed firmly against the bottom of the container generated. In this position, the fixed metal frame is locked to the bottom of the container by means of bolts.

Furthermore, a bottom closure is known (DE-PS 5 47 568), in which a swivel frame is provided, which can be rotated on a shaft around the entire floor lock inserted in the floor stone clamp by means of an eccentric.

This eccentric is used both to generate the sealing pressure and to maintain it Pressure and to connect the two refractory

Value can be done by passing these values on a data processing system, if necessary, an optimization or a statistical recording is carried out will. In addition, the sealing pressure can be adjusted to the optimum value in each case.

A wear or a deformation of the individual parts, especially the refractory plates, affects thus the generation of the optimal sealing pressure between the refractory panels each time the Slider closure at the bottom of a ladle is only insignificant.

The desired sealing pressure can also be achieved when using components with other dimensions reach.

When the piston-cylinder unit 36 and its hanger 35 remain inserted and the pressure measuring device is always connected to the pressure line, can also the force generated is determined during casting and thus an optimal sealing pressure is maintained will. Any disruptions or changes in the various working conditions can therefore be taken immediately responded.

The pressure values read can be systematically analyzed and checked to carry out a regulation are fed back to the fluid pressure device in order to set the optimum sealing pressure in each case to allow between the refractory panels.

The fluid pressure device can be operated either pneumatically or hydraulically, and the generated Force can be applied to the sealing pressure via a linkage, a lever mechanism or a screw mechanism for the refractory panels to be implemented.

All conventional embodiments can be used as the fluid pressure device, that is to say in a straight line devices that can be displaced or operated by rotation, additional rods or lever mechanisms to amplify the force generated by the fluid pressure device, a combination of a hydraulic or pneumatic device with a screw device and finally an additional one Electric motor and a screwing device.

To monitor the sealing pressure, a pressure relief valve or a reducing valve can be used for the fluid pressure device be used.

Resistance wire strain gauges, magnetic strain gauges, hydraulic pressure gauges and spring gauges are used.

In the following, with reference to FIGS. 7 and 8 a locking device with hooks for one Slide gate are described. A lower holding plate 1, which tröntische components, is attached to their s held by a locking metal frame 19 on both sides. It is also detachable from the stationary Metal frame 4 suspended. The surfaces of the sliding, refractory plate 6 and the stationary, refractory plate 5 are indirectly through a fluid deck device (not shown in FIGS. 7 and 8), as already mentioned above. The shutter metal frame 19 is fixedly attached to the stationary metal frame 4 by hooks 24 which are pivotably articulated on the stationary metal frame 4.

When assembling such a slide lock, the container is first brought into a horizontal position so that the bottom 28 of the container runs perpendicular to the supports.

The slide lock is then fully assembled by all components assembled and the desired sealing pressure between the refractory plates 5 and 6 is generated. Then holding brackets 3 t 'des fully assembled slide valve in engagement with

The assembly of the slide valve is so on

carried out the floor under the container, the individual parts, from the stationary metal frame 4 to the downward directed pouring nozzle 7 the ground can be arranged so that the refractory pouring nozzle 7 is directed upwards these parts are fully assembled on the floor.

In detail, the stationary metal frame 4 is placed on the ground that its surface, the comes into contact with the bottom of the container, facing the bottom Then the stationary, refractory plate 5 inserted into the metal frame 4. During this operation, the hooks 24 the bracket can be moved outwards. Then the sliding metal frame on which the sliding, refractory plate 6 and the lower refractory pouring nozzle 7 have been mounted on the stationary, Refractory plate 5 placed on the sliding metal frame 3 is then the finished assembly, consisting from the lower retaining plate 1. the elastic elements, such as springs 13, and the spring

so receiving devices, mounted. Then press then the fluid pressure device (not shown in Figs. 7 and 8) the refractory plates together, wherein the springs 13 are also compressed. As soon as the springs 13 are compressed to a certain length have been, the hooks 24, each of which has a handle 81, are inwardly rotated and brought into engagement with protrusions protruding from a portion of the lower holding plate 1. In this way, a certain sealing pressure has been set and the assembly of the slide valve closure has been completed

After this operation, the fluid pressure device is removed so that the slide gate valve is at the bottom of the casting container can be attached.
