Anti-concave structure for bottom water tank face plate of electroslag furnace

The utility model relates to an anti-concave structure for a bottom water box face plate of an electroslag furnace and is used for supporting the bottom water box face plate (9) covering on the upper surface of a bottom water box (1). The anti-concave structure is characterized in that supporting elements (2) are arranged on the upper surface of the bottom water box (1), and the number of the supporting elements (2) is 12 to 20. Due to arrangement of the supporting elements, the anti-concave structure can effectively prevent concave phenomenon of the bottom water box face plate, prolongs service life of the bottom water box face plate, shortens replacement period of the bottom water box face plate, reduces economic cost, and does not change the direction of cooling water to influence cooling effect. A steel plate is supported to prevent transformation of the bottom water box face plate.
