That is to say, the width direction boss bar and recess, on both sides of boss bar or recess.

[0038] This implementation, in the process of masonry, finds, and the firebrick of prior art fits more closely and firmly, but the length direction boss bar and width direction boss bar connect part are easy to form slip point, and the close and firm degree is not as good as only setting width boss bar on one side of length boss bar. But the firebrick of this embodiment is easier to smear mud and align with other bricks from the masonry angle, because the width direction boss bar and length direction boss bar are symmetrical left and right and front and back.

[0039] The utility model provides another embodiment, and the length direction's boss bar 2 of cuboid top surface has a, in the middle position of cuboid top surface;The length direction's recess 3 of cuboid bottom surface has a, in the middle position of cuboid bottom surface. The length direction's boss bar and recess can also set multiple according to requirement, but considering the masonry difficulty and cost, setting a is better.

[0040] The present application provides another embodiment, the left or right side of the length direction of the convex rib 2 is provided with 2-4 width direction of the convex rib 4, the left or right side of the length direction of the groove 3 is provided with 2-4 width direction of the groove 5.

[0041] The present application provides another embodiment, the right side of the cuboid is provided with one height direction of the convex rib, which is in the middle position of the right side of the cuboid; the left side of the cuboid is provided with one height direction of the groove, which is in the middle position of the left side of the cuboid. Multiple can also be provided, but considering the difficulty and cost of masonry, it is better to provide one.

[0042] The flue wall firebrick is provided with grooves and convex ribs on the left and right sides, which ensures that the transverse surface of the flue wall will not be deformed.

[0043] The present application provides another embodiment, the cross section of the convex rib on the top surface and the side surface of the firebrick is semicircular, and the cross section of the groove on the top surface and the side surface of the firebrick is semicircular.

[0044] The semicircular convex rib and groove are easier to apply fireproof mortar, and relative to the prior art, the convex rib with a certain height is more uniform in applying fireproof mortar, and the firebricks are more closely and firmly fitted. Figure 1

[0045] The firebrick structure of the present application is more firm and has a lower deformation rate relative to the firebrick with the same material and other shapes.

[0046] The above only describes the preferred embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.​
