[0002] In the steel industry, the steel in the ladle needs to be heated to a molten state. The ladle is used in steel mills and foundries to receive molten steel and perform pouring operations in front of open hearth furnaces, electric furnaces or converters. When the ladle is in use, the molten steel in the ladle needs to be weighed by an electronic scale.

[0003] When the existing electric furnace ladle electronic scale is in use, the ladle base is easily offset when the molten steel is poured into the ladle, resulting in the molten steel being easily spilled. In view of this, we propose an electric furnace ladle electronic scale. Utility Model Content
