Description

one

This invention relates to ferrous metallurgy, in particular, to structures of elements of metallurgical furnaces.

A slag is known, including a damper, equipped with a grip, a suspension bracket fixed on the frame of the working platform, and a traverse that is permanently connected to the damper with the help of cable 1.

The disadvantage of this slag is the inconvenience of locating the gripper connection unit with the suspension roller under the working platform, as a result of which the operator does not see it at the time of installing the valve. The presence of large grips on the removed flap and crosshead makes it difficult to set it in a horizontal position ..

The closest to the proposed technical essence and the achieved result is the open-hearth furnace of the open-hearth furnace, which includes a flap provided with a gripper in the form of two carriages moving along the suspension of the T-section fixed to the working platform frame and parallel to the flap, a traverse permanently connected to the flap cables through the system of blocks for blasting the flap from the butt end of the slag grass and moving along it under the working platform, and the C2 clamps. The disadvantages of the known blade are then the valve does not go into the casting span for removal and replacement of the lining, it requires a special mechanism for pressing it against the end face of the slag grass, the shield is equipped with a complex system of weaning and moving the valve along the end.

The purpose of the invention is to increase the reliability and improve the working conditions of the mill.

The goal is achieved by the fact that the grassland, including the flap and suspension of the flap, interacting with each other by means of a carriage, traverse and

5, the cable system of its connection with the flap is provided with an additional suspension and carriage, the suspensions are arranged parallel to each other and obliquely to the wall of the slagberry, in a plane perpendicular to the axis of the slagberry, the carriages are interconnected by an axis, the axis being rotatable in the vertical plane It is connected to the cable system, and the filament is hinged on this axis. In addition, the flap is equipped with an earring. FIG. 1 shows the proposed device; FIG. 2 shows a section A-A in FIG. 1. Slag from an open-hearth furnace includes a flap 1 hinged with two hooks 2 on the axis 3. Axis 3 is connected via blocks 4 by cable 5 to the cross member 6 mounted on the stand 7. Axis 3 connects the carriages 8 to each other. The carriages 8 are mounted on suspensions 9 having a T-section, arranged parallel to each other and obliquely to the wall 10 of the slag, in a plane perpendicular to the axis of the slag; The flap 1 is equipped with a stud 11 for removal by the hook 12. The traverse 6 can be fixed on the bench 13. The slag is operated in a barely blunt manner. Before removing the slag, the valve 1 is removed. To remove the valve 1, the crane hook 12 seizes the yoke 6, which is connected to the axis 3 by the cable 5 through the system of blocks 4, and starts to be lifted with a small tap to the side of the pouring bay. , and set on it, secured in the restrictive stops. The axis 3 at this time, together with the flap 1 installed on it, moves on the carriages 8 on the suspension 9 from under the working platform to the position (conditional line, fig. 2), and when the rollers of the carriages reach the stops of the suspension, they stop axis 3 continues to move in a vertical plane around the axis of the rollers of the carriage 8 and moves to such a position that the valve 1 is removed and installed without difficulty for the operator. After completion of the slag cleaning campaign, a flap is installed. Hook 12 crane capture traverse. 6, is raised to its exit from the restrictive stops and retracted toward the pouring spill, while the shutter 1 with the axis 3 is slightly raised. Then the yoke 6 is lowered by the hook 12 along the stand 13 downward until it is installed on the stand 7, while the damper 1 under the action of its own weight moves on the carriages 8 on the suspension 9 towards the end of the slag and presses against it, since the suspension is inclined to the horizontal. The cable 5, after installing the valve 1 and the cross bar 6, slightly sags. The proposed design of the slag allows the shutter to self-clamp to the butt of the shlakivik, improves the conditions of the shutter installation, and increases the reliability of the work of the shlakovik. The operating conditions of the traverse with cables, which are located in a specially designated place, have been improved. The annual economic effect from using the invention per furnace is 10-15 thousand rubles. Claim 1. Slag of an open-hearth furnace, including a damper and damper suspension, interacting with each other through a carriage, a traverse and a cable system for its connection with a damper, characterized in that, in order to improve working conditions and increase reliability, the slag is equipped with an additional suspension and the carriage, the suspensions are parallel to each other and obliquely to the wall of the slag, in a plane perpendicular to the axis of the slag, the carriages are interconnected by an axis, the axis being rotatable in a vertical direction. It is connected to the cable system, and the valve is hinged on this axis. 2. Slag according to claim 1, characterized in that the valve is provided with an earring.
