Description

Technical Field

[0001] The utility model relates to the technical field of a converter stop seat, in particular to a converter device with a clamping block type stop seat. Background Art

[0002] The converter is an important core equipment in the steelmaking process equipment, and the connection and support system between the converter and the drag ring is the core of the converter equipment. It plays a role in the relative positioning of the furnace shell and the drag ring during the converter shaking process, and also bears the huge gravity of the converter body and the impact load of the converter rotation during the converter rotation. After using the traditional stopper for a period of time, due to the irregular thermal deformation of the converter, a certain gap will be generated between the stopper on the support ring and the stopper on the furnace body, causing the brake pad to gradually fall off. When the converter is tilted, under the strong impact of the furnace body on the stopper, the gap between the upper bracket of the converter and the stopper of the converter gradually increases, resulting in an increase in the impact load of the converter. The huge impact load directly knocks the stopper off, causing the stopper to fail. This will pose a serious hidden danger to the safe operation of the converter equipment. At the same time, during the continuous production of the converter, the furnace has to be stopped frequently, and its short gaps are used to brave the high temperature and heat radiation in a narrow and dangerous environment. In the high-altitude work area, the furnace body and the support ring stopper are urgently treated by plugging and welding. Above the converter is the flue system. There are many fine iron oxide scales on the inner wall of the flue, which form large pieces of slag over a long period of time. After the furnace is shut down, the temperature of the flue decreases, and the slag attached to the inner wall of the flue is at risk of falling off at any time. The welding is carried out just below the flue, and the welding risk factor is very high. Although the converter is shut down, the refractory bricks in the converter still maintain a high temperature. At this time, the furnace body of the converter is still more than 300 degrees high. As long as you touch it, you will be burned. Therefore, welding the stopper is a very high-risk thing. In order to solve the above problems, a converter device with a card block stopper is proposed. Summary of the invention

[0003] The purpose of the utility model is to solve the above problems and provide a converter device with a block-type stopper.

[0004] The specific scheme of the utility model is: a converter device with a card block type stop seat, comprising: a furnace body, a support ring is provided on the furnace body, the furnace body and the support ring are connected by a ball joint, furnace stop seats are provided on the upper and lower sides of the support ring, and the furnace stop seat is fixedly connected to the furnace body; a stop seat corresponding to the furnace stop seat is provided on the support ring, and the stop seat comprises:

[0005] Connecting seats, there are two connecting seats with a gap between them, symmetrically arranged on the supporting ring, and the connecting seats are fixedly connected to the supporting ring;

[0006] A clamping block corresponds to the connecting seat and is threadedly connected to the connecting seat. The furnace stopper is inserted between two adjacent clamping blocks and is used to limit the relative deflection angle between the furnace body and the support ring when the furnace body rotates.

[0007] Furthermore, the connecting seat is provided with a T-shaped slot, and the clamping block is provided with a T-shaped protrusion matching the T-shaped slot; the T-shaped protrusion of the clamping block is inserted into the T-shaped slot and is tightened and fixed by bolts.

[0008] Furthermore, reinforcing ribs are provided on the outer side of the connecting seat.

[0009] Furthermore, there are three reinforcing ribs, namely a long rib plate, a middle rib plate, and a short rib plate, which are arranged from the inside to the outside.

[0010] The utility model has the following beneficial effects: the utility model has a simple structure and is easy to operate. The stop seat is detachable. When the card block is deformed during the collision with the furnace stop seat, resulting in damage or excessive gap, it is only necessary to remove the damaged card block and replace it with a new one for continued use. While ensuring work efficiency, there is no need for secondary welding, avoiding safety hazards caused by welding, and greatly reducing the maintenance cost of the converter.
