Heat-insulating plate for inclined plane of continuous casting cooling bed

The utility model relates to a heat-insulating plate for an inclined plane of a continuous casting cooling bed. The heat-insulating plate is provided with a water cooling cavity, wherein the water cooling cavity is provided with a water inlet and a water outlet; the heat-insulating plate for the inclined plane of the continuous casting cooling bed is bias fixed on a side wall of a roller bed facing to an operation chamber; and an inclined angle at a certain degree is formed between the heat-insulating plate and a billet. At a working moment, water is introduced and is used for cooling and taking away the heat which is radiated when red hot billets continuously pass by the cooling bed, so that a working condition of continuous casting operators is improved. The heat-insulating plate can be widely used as a device for improving the working condition of continuous casting operation in a steel mill.
