Abstract
The utility model discloses an anti gunning refractory that drops of andalusite corundum middle expects for the andalusite corundum, and its outside cladding has a flame retardant coating, the tip is wrapped up by the wearing layer about the andalusite corundum material flame retardant coating, a serial communication port, andalusite corundum material is equipped with the arch, and the wearing layer is equipped with the recess of fitting mutually with the arch, and the arch can be combined closely with the recess. Compared with the prior art, the utility model, the refractoriness is high, the heat resistanceheat resistant is shaken, stability is good, wear -resisting by force, has improved the life of product, has reduced the maintenance cost, and lug and recess block between andalusite corundum material and the wearing layer have improved the anti -drop function greatly simultaneously.
Description
Technical field
This utility model belongs to fire resisting material field, is specifically related to a kind of low cement jet of aluminium oxide and shoots material。
Background technology
Along with the fast development of China's building materials industry, the demand of cement increases day by day, and on the cement drying production line maximized, the refractory material at coal injection pipe and kilneye place is crucial, continuous properly functioning most important to cement kiln。From the external a complete set of cement kiln equipment introduced, the castable at coal injection pipe position, service life is also very short。
Coal injection pipe position work under bad environment, the requirement of refractory material is also harsh, do not require nothing more than high temperature resistant and good thermal shock resistance, and exigent mechanical strength and wearability, and also otherwise blocking coal injection pipe outlet。The castable of the common coal powder injection mouth of pipe, without solid shape, is one layer and is layered on kilneye or the corral castable at the mouth of pipe, if direct one layer is layered on kilneye, easily causing coal injection pipe place does not have resistance to material to cover, have impact on kiln temperature, bring the decline of work efficiency, even can cause potential safety hazard；If being directly trapped among the coal powder injection mouth of pipe, due to the reason without solid form of castable, it is easy to the blocking mouth of pipe causes coal powder injection insufficient, extends the working time, improves the cost of work。
Summary of the invention
Goal of the invention: the purpose of this utility model is in that for the deficiencies in the prior art, it is provided that a kind of low cement jet of aluminium oxide shoots material。
Technical scheme: in order to reach foregoing invention purpose, this utility model is specifically achieved like this: a kind of Andalusite corundum peel gunning refractory, centre is Andalusite corundum material, flame retardant coating it is coated with outside it, described Andalusite corundum material flame retardant coating upper and lower end parts is wrapped up by wearing layer, it is characterised in that described Andalusite corundum material is provided with projection, wearing layer is provided with the groove fitted mutually with projection, and projection can be combined closely with groove。
Wherein, described flame retardant coating is fire-resistant asbestos。
Wherein, described wearing layer is steel fibre。
Wherein, described wearing layer and Andalusite corundum material, flame retardant coating junction are filled with PVC adhesive。
Wherein, described Andalusite corundum material top and top are respectively provided with 1 projection, and wearing layer respective protrusions place respectively sets groove。
Beneficial effect: this utility model is compared with prior art, refractoriness height, anti-thermal shock, good stability, wear-resisting by force, improve the service life of product, decrease maintenance cost, simultaneously projection between Andalusite corundum material and wearing layer and groove engage, and substantially increase anti-drop function。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
Andalusite corundum peel gunning refractory as shown in Figure 1, centre is Andalusite corundum material 1, flame retardant coating 2 it is coated with outside it, described Andalusite corundum material 1 flame retardant coating 2 upper and lower end parts is wrapped up by wearing layer 3, described Andalusite corundum material 1 is provided with protruding 11, wearing layer 3 is provided with the groove 31 suitable with protruding 11 phases, protruding 11 can combine closely with groove 31, flame retardant coating 2 is fire-resistant asbestos, wearing layer 3 is steel fibre, described wearing layer 3 and Andalusite corundum material 1, flame retardant coating 2 junction is filled with PVC adhesive, described Andalusite corundum material 1 top and top are respectively provided with 1 projection 11, wearing layer 3 respective protrusions 11 place respectively sets groove 31。
