The adjusting assembly 140, the two sets of balance assemblies 190 and the jackscrews 150 form a four-point connecting structure, so that the side sealing plate assembly 120 can be better guaranteed to stably advance and retreat, proper output force can be given when the side sealing plate assembly runs to a working position, the side sealing plate 124 can be guaranteed to seal molten steel in a molten pool in a working state, abrasion of the side sealing plate 124 can be reduced, and the service life of the side sealing plate 124 is prolonged.
The side sealing plate 124, the back plate 123 integrating mechanism and the support 121 are isolated by the isolating sleeve 170, a certain space is reserved, which is called an air spacing layer, and the heat conducted to the side sealing plate 124 by molten steel can be effectively reduced through the space.
Because the temperature in the whole machine is higher in the whole continuous casting process of the thin strip, the moving rod 134, the fixed plate 135 and the seat body 110 on the bracket 121 are communicated with cooling water, so that the mechanism deformation caused by heat radiation generated in the molten steel casting process is avoided.
