Description

The invention relates to metallurgy in the field of continuous casting, in particular to devices for installing and centering the mold in a continuous casting machine.

The purpose of the invention is to reduce the wear of the working walls of the mold and improve the quality of the ingot,

Fig, 1 schematically shows the proposed device; Fig. 2 shows the layout of the mold on the frame of the swing mechanism.

The mold with its supporting paws 1 is hinged on two-arm levers 2 placed on racks 3 rag-1Y 4 of the swing mechanism e and equipped with a ball bearing 5, secured - 1and on the body of the crystallizer 6.

The device works as follows.

With transverse displacements of the ingot, the force from it is transmitted to the end wall of the mold, causing the levers 2 to change the initial position due to the rotation in the hinges of the pillars 3 paivsbi 4 and in the hinges 7 on the support legs 1. The crystallizer b moves following the criHTKOMj performing aligned The benefits of the ball bearings 5 are directed 8 flat parallel to the jigs and at the same time maintaining uniform contact between the wall crystallizer. The ball bearings 5 are at the same time slate for the exhibition of the Crustaglizer on the machine and facilitate the movement of the mold in the transmission chain - the direction "

OnopHbse mold paws are one piece with the cast mold of the mold. Thus, when the ingot mold is moved to the right or to the left of the equilibrium position, both arms of the lever 2 (Fig. 1), having freedom of pivotal attachment to the legs and freedom in the hinge of the 3 „, are deflected simultaneously with the movement of the crystallizer.

The proposed solution allows

exclude turns

swing) of the mold relative to the axle of the axles when the ingot is shifted in the transverse direction, thereby preventing displacement (damage)

peel ingot in the upper part of the mold, where the thickness and, consequently, its strength is small.

The experience of curvilinear continuous casting machine operation showed the inter-regional control

resistance of the crystallizer due to wear of the working walls.

Removing molds with MHJ73 DD1Ya replacing the working walls of the oststestsya is through 60-70 spilled bottoms,

t, e, as far as wear of the end (narrow) walls. For the lifetime of the narrow walls up to 300 castings. Wear on the lateral (wide) walls of the upper arm and the service life of wide walls

up to 900 heats.

Thus, the durability of the wide walls is 3 times as long and for a period of time; if only one pair of side walls is replaced by three pairs of end walls

The use of the proposed device. TEa allows one to achieve uniform contact of the ingot with the walls of the crystal: lysatoria, which reduces them to: improves, improves the conditions; heat exchange between ingots and walls and, consequently, increases the quality of the metal.
