Detailed Description
The technical scheme of the utility model is further described by specific examples.
Example 1
The utility model provides a novel resistant firebrick, includes fire-proof brick 1 and cooling shell 2, and cooling shell 2 is part parcel shell structure, and fire-proof brick 1 sets up in cooling shell 2 inboardly, is equipped with cooling through groove 3 in the cooling shell 2 outer wall, and interface 4 at cooling through groove 3 both ends sets up on cooling shell 2's outer wall.
The fireproof brick 1 is of a hexahedral brick structure, and the cooling shell 2 is of a pentahedral shell structure matched with the fireproof brick 1.
The cooling shell 2 is composed of a plurality of cooling plates 5, and the cooling through grooves 3 are arranged in spiral lines on the cooling plates 5.
The cooling housing 2 is made of metal.
The working principle of the scheme is as follows, as shown in fig. 1-2, the fireproof brick 1 is arranged in the cooling shell 2, one side of the fireproof brick 1 is exposed out of the cooling shell 2, the exposed part faces to a central heat source, an interface 4 arranged on the cooling shell 2 is connected with a refrigerating device, cooling liquid or gas is injected into the cooling shell to cool the whole, and the cooling shell 2 has the functions of reducing the temperature and corrosion of the fireproof brick 1, so that the corrosion resistance and the high temperature resistance of the fireproof brick are effectively improved. The shape and the size of the fireproof brick 1 can be adaptively adjusted according to actual use, the cooling shell 2 consists of a plurality of cooling plates 5, and the connecting structures among the cooling plates 5 are mutually connected by matching with the rotating structure of the fireproof brick 1. Preferably, the cooling through grooves 3 on the single cooling plate 5 are arranged in spiral lines, and the refrigerating effect is better.
Example two
As shown in fig. 3 to 4, on the basis of the first embodiment, the fireproof brick 1 is provided with a setting groove 6, and the cooling shell 2 is provided with a setting hole 7 matched with the setting groove 6.
The setting groove 6 and the setting hole 7 are of matching structures and are used for penetrating through a brick body to place an oxygen gun or a carbon gun, so that the situation that peripheral refractory bricks are corroded more easily due to the fact that refractory bricks around the gun body are not easy to pile up in the prior art is avoided, pits are formed in the periphery, the integral structure of the furnace body refractory bricks is damaged, and the service life of equipment is prolonged.
The foregoing describes one embodiment of the present utility model in detail, but the description is only a preferred embodiment of the present utility model and should not be construed as limiting the scope of the utility model.
