Abstract

The invention provides a thermal-insulated lifting appliance for a steel ladle. The thermal-insulated lifting appliance comprises a hook body, a hood body and an opener / closer fixedly connected with the hood body, and is characterized in that a sub-hook used for lifting the opener / closer is arranged on the hook body; the opener / closer comprises a base connected with the hood body; shaft sleeves are arranged on two sides on the base; each shaft sleeve is connected with a swing arm through a first shaft; a closing stop block and a rocker are separately welded on the inner side of each swing arm;one sides of two opening stop blocks are mounted in a shaft sleeve in the base through second shafts; the other side of each opening stop block is connected with the corresponding rocker through a third shaft; and locking springs are arranged at the upper ends of the rockers and the base. Through the adoption of the thermal-insulated lifting appliance, the technical problems that in the lifting process of the steel ladle, heat of molten steel in the steel ladle is lost, and a crane hook and a steel wire rope are subjected to thermal deformation and degradation can be effectively solved.

Description

Technical field: [0001] The invention relates to a ladle heat preservation lifting sling, which belongs to the technical field of steel metallurgical machinery equipment. Background technique: [0002] In the steelmaking production process of the modern metallurgical industry, bridge cranes are usually used to realize the lifting operation of the ladle to realize the circulation of molten steel between various smelting process points. However, in the actual production process, due to the different smelting processes of different steel grades and the limitations of the production line layout, there are varying degrees of waiting for the ladle during the hoisting process. The heat of the molten steel in the ladle is directly diffused to the outside through the open ladle mouth. The loss causes the temperature of the molten steel on the upper part of the ladle to drop, which affects the accuracy of the normal molten steel smelting index. At the same time, the hook girder of the bri...
