Description

floats in buckets with replaceable funnels mounted on sliding rail carts; Fig. 2 shows a device with interchangeable funnels mounted non-medically on the opposite gutter.

The device (see Fig. 1) consists of a stationary trench I, located beneath it between two adjacent railway tracks Olya buckets 2 and 3 of the rolling one, trough 4 (in this case swinging in a vertical plane) with two drain toes and installed under each drain; The sock is replaceable funnels 5. To facilitate replacement and repair, replaceable funnels 5 are mounted on sliding carts 6. The latter, in turn, are mounted on rails 7, laid on the supporting structures of the blast furnace foundry. The lower part of the funnel 5 is a vertical pipe, the axis of which lies in the same plane with the axis of the railway track in the area of casting. The funnel is internally lined with refractory material. Along with the lining, it may have a water-cooled housing.

In another embodiment of the device (see: Fig. 2), the interchangeable funnels 5 are not mounted on the sliding carriages, but directly on the movable channel 4, to which they are attached with bolts with a wedge tie.

The device according to the first embodiment is expedient to use in those cases when there is no backup device for it by the project of the casting yard, and its maintenance with the casting crane is difficult. The presence of trolleys allows you to quickly roll away a replaceable funnel away from the axis of the movable chute for inspection and repair and install a new funnel in its place, which can be mounted on the same cart as the first one or on your own cart.

The device in the second variant is preferable to use when there is a redundant device and, if possible, with normal crane service, with a two-piece quick-change funnel.

In the case of the movable trough being pivoted in a horizontal plane, one replaceable funnel is installed under its drain toe, and the other is mounted directly on the trough (on the side) parallel to its receiving part.

The device works as follows.

During casting, the melt from the stationary chute 1 enters the swinging chute 4

and through one of its drain socks it is guided into the bucket 2, the passage through the funnel 5. Regardless of the nature of the path of movement of the melt jet, in the section between the rocking chute and the funnel, the jet leaves the latter vertically, going to the center of the bucket. With such a filling, an axisymmetric distribution of temperatures in the lining and bucket body is provided, there are no local overheatings of its temperature.

At the end of the filling of the bucket 2, the drive chute 4 is electrically driven in the direction of the bucket 3, which stands on an adjacent track. In the process of filling

of this bucket through the right funnel 5, the bucket composition with the filled bucket 2 is moved a step, installed under the left funnel 5 an empty bucket. These operations are then repeated until the completion of casting.

The implementation of the proposed device, due to its advantages, allows more than double the durability of buckets.
