Abstract
Disclosed is a refractory brick for restoring a kiln barrel. A groove (4) is formed in one side of a wedge-shaped surface (2) of the refractory brick (1), and protrusions (3) matched with the groove (4) are arranged at the corresponding position on the other side of the wedge-shaped surface (2). When the refractory brick is used, the groove and the protrusions of adjacent refractory bricks can be meshed mutually, so that when the cooperation of the refractory bricks is loosened, the refractory bricks are prevented from falling or collapsing under the effect of gravity, the production cycle of the rotary kiln can be prolonged, and production cost is effectively reduced.
Description
Technical field
The utility model relates to a kind of heat insulation and insulation material of reduction kiln cylindrical shell, is a kind of refractory brick of producing used reduction kiln cylinder inboard wall in reduced ilmenite of building specifically.
Background technology
Be used for the used reduction kiln cylindrical shell refractory brick of reduced ilmenite production and be generally wedge shape, namely major part is pressed close to the cylindrical shell medial surface, and the microcephaly is working face, and the wedge-shaped surface of both sides is the plane.The refractory brick of this structure in use for some time, owing to the reason such as expanding with heat and contract with cold, contact surface produces matching loose because the slit occurring between part brick and the brick, under the effect of refractory brick self gravitation, constantly friction of contact surface between brick and the brick, cause the slit further to enlarge, can brick occur falling when serious or refractory brick collapses, make reduction kiln be forced to stop kiln.
Summary of the invention
The purpose of this utility model provides a kind of reduction kiln cylindrical shell refractory brick, can effectively prevent from producing matching loose between brick and the brick, thereby can prolong the rotary kiln production cycle, effectively reduces production costs.
A kind of reduction kiln cylindrical shell refractory brick that the utility model provides, wedge-shaped surface one side of refractory brick is fluted, and the opposite side corresponding positions is equipped with the projection that adapts with groove.
In above-mentioned, groove and projection all have one, are separately positioned on the wedge-shaped surface medium position.
The utlity model has following advantage:
Because wedge-shaped surface one side of refractory brick is fluted, opposite side has the projection that adapts with groove, during use, groove and projection can be engaged between adjacent refractory brick, when between refractory brick brick and brick, producing matching loose, can avoid under the self gravitation effect, occurring falling brick or the refractory brick phenomenon that collapses, thereby greatly improve reduction kiln cylindrical shell refractory brick service life, simultaneously also prolong the rotary kiln production cycle, effectively reduced production cost.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Fig. 4 is use state diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of reduction kiln cylindrical shell refractory brick that the utility model provides, wedge-shaped surface 2 one sides fluted 4 of refractory brick 1, the opposite side corresponding positions is equipped with the projection 3 that adapts with groove, groove 4 and projection 3 all have one, size shape is corresponding, is separately positioned on wedge-shaped surface 2 medium positions.
Fig. 4 is use state diagram of the present utility model, and the major part of refractory brick 1 is pressed close to cylindrical shell 5 medial surfaces, and the microcephaly is working face, and the groove 4 of a refractory brick 1 is engaged with the projection 3 of adjacent refractory brick when laying bricks.
Claims (3)
1. a reduction kiln cylindrical shell refractory brick is characterized in that, wedge-shaped surface (2) one sides fluted (4) of refractory brick (1), and the opposite side corresponding positions is equipped with the projection (3) that adapts with groove.
2. a kind of reduction kiln cylindrical shell refractory brick according to claim 1 is characterized in that, groove (4) and projection (3) all have one.
3. a kind of reduction kiln cylindrical shell refractory brick according to claim 1 and 2 is characterized in that, groove (4) and projection (3) all are arranged on wedge-shaped surface (2) medium position.
