Referring to fig. 1 and 2, an embodiment of the present invention is:

the utility model provides a kiln is able to bear or endure firebrick, includes connecting brick 1 and end brick 2, fixed recess 3 has been seted up at the upper and lower both ends of connecting brick 1, end brick 2 is equipped with the adaptation fixed recess 3's plug 4, the first through-hole 5 that link up is seted up at the center of connecting brick 1, the adaptation is seted up at the center of end brick 2 the second through-hole 6 of first through-hole 5, it wears to be equipped with a plurality of heat conduction steel columns 7 to lie in on connecting brick 1 the outside of first through-hole 5, the tip of heat conduction steel column 7 is worn out the terminal surface of connecting brick 1, set up the adaptation on the end brick 2 the third through-hole 8 of heat conduction steel column 7.

The connecting brick 1 and the end brick 2 are mutually spliced to form the refractory brick of the kiln, after the end bricks are collided and damaged, the end bricks are broken and correspondingly replaced, the connecting brick 1 can be repeatedly used, and the production cost is greatly saved.

And the heat-conducting steel column is inserted into the third through hole, the plug is inserted into the fixing groove, and the plurality of combining parts are adopted for splicing and matching, so that the combination stability of the connecting brick 1 and the end brick 2 is ensured.

Because the connecting brick 1 is relatively long in length and the middle part of the connecting brick is provided with the through first through hole, the overall strength is weakened, the arranged heat-conducting steel columns 7 surround the outer side of the first through hole to fulfill the aim of complementing or even enhancing the strength of the connecting column, and the number of the heat-conducting steel columns can be specifically arranged according to actual needs by technical personnel in the field.

The structure that adopts first through-hole, heat conduction steel column and third through-hole can carry out heat-conduction more fast. The firing efficiency of the refractory bricks is improved.

The plug 4 and the end brick are integrally formed, and the second through hole 6 penetrates through the plug 4.
