Detailed Description

The utility model will be further described with reference to the drawings and the specific embodiments

Example 1

As shown in fig. 1 to 4, the present utility model provides a technical solution: including firebrick main part 1, the equal fixedly connected with L type fixture block 2 in both ends at firebrick main part 1 top, spacing draw-in groove 3 has all been seted up at the both ends at firebrick main part 1 bottom, and two rectangle breach 7 have been seted up to one side of firebrick main part 1, and one side fixedly connected with two bar pieces 6 of rectangle breach 7 are kept away from to firebrick main part 1.

Through the above embodiment, when the refractory brick main body 1 is used, the limiting clamping groove 3 at the bottom of the refractory brick main body 1 is aligned with the L-shaped clamping block 2, then the L-shaped clamping block 2 is slid into the limiting clamping groove 3, and then the refractory brick main body 1 is moved forwards, so that one end of the L-shaped clamping block 2 enters the inside of the limiting clamping groove 3, thereby limiting the refractory brick main body 1 in the vertical direction, enhancing the stability, and simultaneously, one side of the strip-shaped block 6 is contacted with one side of the inner wall of the rectangular notch 7 in the horizontal direction, thereby limiting the refractory brick main body 1 in the horizontal direction by utilizing the matching of the strip-shaped block 6 and the rectangular notch 7, further enhancing the stability of the refractory brick main body 1 in the masonry process, thereby preventing the adverse effect of the deformation of the refractory brick on a furnace wall under the high temperature effect, enabling different refractory brick main bodies 1 to mutually support, and enhancing the practicability of the refractory brick.
