Collection device for overflow steel slag for continuous casting tundish

Abstract

The invention discloses a collection device for overflow steel slag for a continuous casting tundish. The collection device comprises a slag basin; a supporting platform is arranged between a tundish and a rotary table; tracks which penetrate through the tundish and the rotary table are arranged on the supporting platform; a track trolley which can move along the tracks are arranged on the tracks; and the slag basin is placed on the track trolley. According to the collection device, the track trolley can drive the slag basin to move to the underneath of an overflow hole of the tundish driven by a drive mechanism, so that the slag basin can bear and receive the steel slag which overflows out of the overflow hole of the tundish; in addition, the track trolley can also drive the slag basin to leave the underneath of the overflow hole of the tundish and move out of the space between the tundish and the rotary table, so that the travelling trolley can hoist the slag basin without being influenced by the rotary table; a controller which can control the drive mechanism so as to control the movement of the track trolley is also arranged on the supporting platform; and the collection device for the overflow steel slag for the continuous casting tundish can also safely and reliably collect the steel slag which overflows out of the overflow hole of the tundish without influencing the production.

Description

technical field [0001] The invention relates to the field of steelmaking and continuous casting equipment, in particular to a collecting device for continuous casting tundish overflow steel slag. Background technique [0002] During continuous casting, the rotary table will turn the ladle containing molten steel to the top of the tundish, and then pour the molten steel in the ladle into the tundish. At this time, the rotary table is in the pouring position; steel slag will be generated on the surface of the molten steel in the tundish , too much steel slag will affect the pouring work of molten steel, so a tundish overflow port will be opened on the side wall of the tundish near the turntable to make the steel slag overflow the tundish, usually a slag is placed between the tundish and the turntable The slag basin is used to receive the steel slag overflowing from the overflow port of the tundish. When the slag basin is full of steel slag, it needs to be hoisted by a crane to...

[0002] During continuous casting, the rotary table will turn the ladle containing molten steel to the top of the tundish, and then pour the molten steel in the ladle into the tundish. At this time, the rotary table is in the pouring position; steel slag will be generated on the surface of the molten steel in the tundish , too much steel slag will affect the pouring work of molten steel, so a tundish overflow port will be opened on the side wall of the tundish near the turntable to make the steel slag overflow the tundish, usually a slag is placed between the tundish and the turntable The slag basin is used to receive the steel slag overflowing from the overflow port of the tundish. When the slag basin is full of steel slag, it needs to be hoisted by a crane to replace the full slag basin with an empty slag basin. The top of the basin makes it impossible to use the crane to hoist the slag basin in time. Only when the ladle is poured and the turntable is rotated 90 degrees away from the pouring position can the crane be used to lift the slag basin, which will lead to slag filled with steel slag. If the basin cannot be replaced in time, the excess steel slag will overflow from the slag basin, and the overflowing steel slag will bring a great burden to the subsequent cleaning work. In addition, because the slag basin is between the intermediate tank and the rotary table, the hoisting position will be relatively large. It is narrow and narrow, which makes the crane hoisting work more dangerous and takes a long time, which will greatly reduce production efficiency and bring great safety hazards
