Abstract
The invention relates to a novel special coal-injection duct head prefabricated part of a dry process cement rotary kiln. The novel special coal-injection duct head prefabricated part comprises a prefabricated part body in a hollow cylindrical shape. The cross section of the prefabricated part body is circular, and the prefabricated part body is made of corundum mullite castable. The novel special coal-injection duct head prefabricated part is high in quality, not prone to being peeled off, abrasion resistant, scouring resistant and long in service life.
Description
Technical field
The present invention relates to a kind of prefabricated component, be specifically related to a kind of new type nonaqueous cement rotary kiln coal powder injection tube head special precast part.
Background technology
At present, the coal injection pipe head special precast part on market is various, but most of service life is shorter, can not realistic work requirements.Most of coal injection pipe head special precast parts easily come off, and material is easily peeled off, thereby need repeated multiple times trimming, bring great inconvenience to actual production work, the wearability of most of prefabricated component simultaneously, and resistance to impact is poor.
Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome deficiency of the prior art, provides a kind of high-quality, incrust, wear-resisting, resistance to erosion, the new type nonaqueous cement rotary kiln coal powder injection tube head special precast part of long service life.
Technical scheme: in order to solve the problems of the technologies described above, a kind of new type nonaqueous cement rotary kiln coal powder injection tube head special precast part of the present invention, it comprises prefabricated part body, described prefabricated part body be shaped as hollow circular cylinder, the cross section of described prefabricated part body is circular, and described prefabricated part body adopts corundum-mullite castable.
The internal diameter of described prefabricated part body is between 350-550mm.
The external diameter of described prefabricated part body is between 430-630mm.
The length of described prefabricated part body is between 500-800mm.
Beneficial effect: compared with prior art, its remarkable advantage is in the present invention: overall structure of the present invention is simple, and dimensions meets the requirements, adopt corundum-mullite castable, improved service life, improved wear-resisting, the abrasion resistance of product simultaneously, product quality is higher.
Accompanying drawing explanation
Fig. 1 is perspective view of the present invention;
Fig. 2 is cross section structure schematic diagram of the present invention.
Wherein:
1, prefabricated part body
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of new type nonaqueous cement rotary kiln coal powder injection tube head special precast part of the present invention, it comprises prefabricated part body 1, described prefabricated part body 1 be shaped as hollow circular cylinder, the cross section of described prefabricated part body 1 is circular, and described prefabricated part body 1 adopts corundum-mullite castable; The internal diameter of described prefabricated part body 1 is between 350-550mm; The external diameter of described prefabricated part body 1 is between 430-630mm; The length of described prefabricated part body 1 is between 500-800mm.Overall structure of the present invention is simple, and dimensions meets the requirements, and adopts corundum-mullite castable, has improved service life, has improved wear-resisting, the abrasion resistance of product simultaneously, and product quality is higher.
The invention provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications; these improvements and modifications also should be considered as protection scope of the present invention, in the present embodiment not clear and definite each part all available prior art realized.
