Description

The invention relates to metallurgy, in particular, to devices used to prevent metal from splashing during pouring into a container.

The purpose of the invention is to improve the quality of the surfaces of the castings and to increase the safety of the work, both by eliminating splashing and by eliminating manual labor in extracting the damper from the molten metal.

FIG. Figure 1 shows schematically an embodiment of the drain section of the chute before and after metal filling; in fig. 2 - the same, during the pouring of the metal; in fig. 3 - the same, top view, before and after metal pouring.

The drain section of the chute for pouring metal comprises a metal lined casing 1, a cantilever axis 2 located at the outlet edge 3 of the section. On the cantilever axis 2 is mounted the sleeve 4 with the lever 5 rigidly connected to it, on

one end 6 of which is mounted a screen 7 made of non-wetted material with cast metal, at the other end 8 is a handle 9. At the outlet edge 3 of the section there is a stop 10 of the vertical position of the lever 5.

On the metal lined casing 1 a gripper-latch 11 of the horizontal position of the lever is placed.

The gutter drain section operates as follows.

Before the metal is poured from the furnace, the end 8 of the lever 5 with the aid of the handle 9 is released from the grip-clamp 11 and with the sleeve 4 is turned on the axis 2 into a vertical position. The screen 7 is also installed in the vertical position. The end 6 of the lever 5 is held in a vertical position by the stop-stop 10.

When pouring a stream of metal on the lined casing 1 passes the discharge edge

3 sections and falls into the closed volume of the screen 7.

The resulting metal splashes remain in the enclosed volume of the screen 7, which improves the quality of the castings, as it prevents splashes from entering the vessel walls (otherwise metal splashes solidify on the walls and with further pouring of the metal, unevenness forms on the side surfaces). As the metal level increases due to the difference in specific weights, the screen 7 pops up and moves the end of the lever 5 b to an intermediate position. Using the handle 9, the lever 5 and with it the screen 7 are placed in a horizontal position, which ensures safe working conditions, since The need to remove the screen 7 manually from under the stream of molten metal.

In the horizontal position, the lever 5 is secured in the catch-holder 11.
