Description

The invention relates to metallurgy, in particular to continuous casting of metal.

Closest to the claimed device is a device (Patent No. 2041011 RU 09/08/1995) containing a casting ladle with a glass, a vertical mold formed by a pair of walls with inclined upper and lower parts of the working surface, each of which is mounted on two parallel horizontal eccentric shafts and each of the working walls of the second pair is located on the lower drive eccentric shaft with the possibility of phase displacement to the first pair of reciprocating motion.

The disadvantages of the known device are that they provide sufficient rigidity when receiving a sheet of a sufficiently large width (more than two meters). To provide the necessary rigidity of the lower eccentric shaft to obtain a sheet of a given thickness variation in width, an increase in its diameter is necessary. This inevitably leads to an increase in the metal consumption of the entire installation and, consequently, to an increase in its cost.

The technical result obtained by the implementation of the inventive device is to reduce the metal consumption of the device.

The device comprises a casting bucket with a glass, a vertical mold, which is formed by a pair of working walls with inclined upper and calibrating lower sections of the working surface and a second pair of working vertical walls that perform reciprocating motion. The calipers on which the side walls are mounted have grooves in the horizontal plane of the lower eccentric shaft, in which sliding rods are mounted, abutting one end against the bearing on the eccentric shaft and the other end into the side cheek of the bed.

The inventive device is characterized by the following essential features.

Restrictive features: a casting bucket with a glass, a vertical crystallizer formed by a pair of walls with inclined sections of the working surface, making complex movement in the vertical plane with deformation in these areas of crystallized metal, and a second pair of working walls, making reciprocating motion.

Distinctive features: the calipers on which the side walls are mounted have grooves in the horizontal plane of the lower drive eccentric shaft, in which sliding rods are mounted, abutting one end against the bearing on the eccentric shaft and the other end against the bed side cheek.

The causal relationship between the totality of the features of the claimed device and the achieved technical result are as follows.

Due to the fact that in the lower part of the mold we have fully crystallized metal, its deformation with a significant width of the sheet stock is associated with great efforts attributable to the lower eccentric shaft. This pressure will be perceived both by the eccentric shaft itself and by the rod abutting against it, which prevents the eccentric shaft from bending in the horizontal plane, which will lead to a better-quality sheet with different thicknesses, to unload the bearings in the bed on which the eccentric shaft rotates.

The drawing shows the structural components of the device (section aa and section bb). The inventive device consists of a vertical mold, comprising a pair of walls 1 with inclined surfaces 2 and calibrating surfaces 3 and a pair of working walls 4.

The working walls of the vertical crystallizer are driven by splined shafts 5 through splined eccentric bushings 6. On the lower shaft there are cylindrical bushings 7, in which the sliding rods 8 abut against the side walls of the frame 9. There are windows 10 for installing the rods in the support in its lower part.

Device operation: liquid metal from a casting device enters a composite mold with movable walls driven by shafts 5 through eccentric sleeves 6, where it is cooled by heat removal by the mold walls, is deformed and pushed down in the form of a sheet of a given cross section. The main deformation of the crystallized sheet occurs in the lower part of the mold and the deformation forces are perceived by the drive eccentric shaft, which bending in the horizontal plane along with the shaft is prevented by sliding rods 8, abutting against one end of the shaft 5 through the cylindrical sleeve 7, and the other end against the side wall of the bed 9. At the same time, the sliding rods not only prevent the shaft from bending, but also unload the bearings in the frame, in which the eccentric shaft rotates.
