Side seal plate for double-roll strip continuous casting and application method thereof

The invention relates to a side seal plate for double-roll strip continuous casting and an application method thereof. The side seal plate for double-roll strip continuous casting comprises side seal plate bodies and a lubricating device. The side seal plate is formed by adhering a concave type shell (1), a heat insulation plate (2), a base plate (3), ceramic plates (4) and a wear-resisting plate (5); the lubricating device is formed by lubricating agent materials (6) and conveyer pipes (7); and the lubricating agent materials (6) are filled in the conveyer pipes (7). The application method comprises the steps of (1) preheating a working surface before casting; then fitting to the end face of a casting roller; and assembling a lubricating agent conveyer device and the conveyer pipes; and (2) during a casting process, enabling the lubricating agent conveying pressure to be larger than the pressing pressure. The side seal plate for double-roll strip continuous casting prepared by the invention not only has an e
