Description

Technical Field

[0001] The utility model relates to the field of the design of the narrow-side protection device of a mold, in particular to a narrow-side protection device for a mold of a slab continuous casting machine. Background Art

[0002] The conventional mold of a slab continuous casting machine is a billet forming device, whose function is to force-cool the molten steel continuously injected into its inner cavity through water-cooled copper plates, conduct out the heat of the molten steel, and gradually solidify it into a billet with the required cross-sectional shape and a certain shell thickness. At the same time, the cross-sectional size of the billet is adjusted by adjusting the positions of the two narrow sides (cold adjustment or hot adjustment) to meet the requirements of different cross-sections.

[0003] Its disadvantage is that when adjusting the cross-section, especially during hot adjustment, the copper plates are easily scratched. After the copper plates are scratched, sticking steel is likely to occur, leading to steel leakage accidents, affecting normal production and increasing production costs. The main reason for the scratching of the copper plates is that during the steel pouring process, steel slag splashes, and the splashed steel slag falls into the corner seams between the narrow-side copper plates and the wide-side copper plates or between the narrow-side back plates and the wide-side copper plates. Then, when adjusting the cross-section, the steel slag scratches the copper plates. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that during the steel pouring process, steel slag splashes, and the splashed steel slag falls into the corner seams between the narrow-side copper plates and the wide-side copper plates or between the narrow-side back plates and the wide-side copper plates. Then, when adjusting the cross-section, the steel slag scratches the copper plates.

[0005] To solve the above problems, the technical solution adopted by the utility model is as follows: The utility model is a narrow-side protection device for a mold of a slab continuous casting machine, including a bottom plate, a silica gel plate, a pressing plate, and fixing bolts. The bottom plate is placed in a fitting manner on the mold, the silica gel plate is placed in a fitting manner on the bottom plate, the pressing plate is pressed on the silica gel plate, mounting holes are respectively provided on the bottom plate, the silica gel plate, and the pressing plate, the fixing bolts penetrate through the mounting holes and are threadedly connected with the mold, and the bolt heads of the fixing bolts are in close contact with the pressing plate.

[0006] Further, there are four groups of the silica gel plates.

[0007] Further, there are multiple groups of the mounting holes and multiple groups of the fixing bolts.

[0008] Preferably, M12 bolts are used as the fixing bolts.

[0009] The beneficial effects achieved by the utility model by adopting the above structure are as follows:

[0010] 1. The protection effect is significantly improved, effectively avoiding the scratching of the copper plates.

[0011] 2. The cost of this device is relatively low and it is convenient to replace. Description of the Drawings
