Description

[Detailed description of the invention] This invention relates to converter slag treatment, and includes a mechanism for rotating the cooling vessel to take out the cooled and solidified converter slag from the cooling vessel, and a mechanism for fixing the cooling vessel to the rotating mechanism. Then, the cooling container is turned by a turning device equipped with a cover and a hood for collecting dust generated during the removal. The present invention relates to a turning device which has the advantage of being able to completely collect dust generated during turning and taking out by suctioning it from the hood, and also making it possible to make the space for processing converter slag compact.

Conventionally, the converter slag processing method is a natural release method in which the converter slag remaining in the converter after steel tapping is discharged into a slag truck, and the slag truck is transported to a slag pit and discharged. The cooled and solidified converter slag is crushed by bulldozers and loaded onto pallet trucks, and the dust produced during this process is large, creating problems in terms of the work environment for workers and pollution prevention, and is also discharged into the slag pit. Because the converter slag has a thick layer, cooling takes only 3 to 4 hours, and a large space is required. Also, JP-A-50-66405, JP-A-51-
147494, JP-A No. 52-42494, etc., the converter slag treatment process described in Japanese Patent Application Publication No. 52-42494 is such that the converter slag remaining in the converter after being tapped in the converter is discharged via a slag steel truck into a cooling container, where it is cooled and solidified. After that, the cooling container is tilted and taken out and crushed, followed by a conveyance process. In particular, when tilting the cooling containers to discharge the slag, one end of the cooling containers arranged in parallel is fixed and the other end is lifted by a crane, etc., and then the slag is placed on a slag receiving truck and transported to the conveyance process. However, dust is generated during the tilting, and it is difficult to collect this dust because the dust collection area is wide. Dust collectors require large capacity, and since multiple cooling containers are arranged in parallel and fixed,
Converter requires a large space for slag treatment.

The present invention solves the above-mentioned problems.The cooling vessels are not fixedly arranged in parallel, but have a structure that can be transported by a crane or the like. By placing and fixing the container on a dedicated turning table and turning it, the dust is generated locally, making it easy to collect dust, and it is also intended for processing in a narrow space. In other words, when processing converter slag, the converter slag is cooled and solidified in a cooling container with a shallow bottom and a wide opening. Possible mounting platform 26
A movable rod 17 is arranged horizontally below the turntable 6, and the tip of the rod fixes the turntable 6 and a part of the stand 26 with a connector via a lever 31. A guide 10 is placed on one long side of the turntable 6.
