Definitions
- the invention relates to a heat and wear-stressed installation element, in particular segment for assembling a dip tube, the central one from above in a lined with fireproof material Cyclone separator of a cement clinker production line protrudes and can be hung on the cyclone ceiling.
- the invention is based, in particular an installation element Segment for assembling a heat and wear segmented dip tube for one with refractory Lined cyclone material of a cement clinker production line to create, the individual built-in element with a Length can be manufactured and assembled even greater than 120 cm should be characterized by a long service life.
- the heat-resistant and wear-resistant according to the invention Built-in element is that it's a composite body consisting of a comparatively thin-walled and lightweight metallic body, on the webs of a metallic grid-like grate are arranged, the grid openings with a heat resistant and against mechanical and chemical Influences of wear-resistant ceramic mass are filled.
- the heat-resistant ceramic mass in the grid openings of the Rust, which can be elastic, e.g. B. expanded metal grid, poured and / or injected and / or injected / vibrated and / or pressed in.
- the heat-resistant ceramic mass is in any case with the Production of the composite body according to the invention is flowable and it can also be done by additional heat treatment such as Sintering, tempering etc.
- the ceramic mass has e.g. B. silicon carbide (SiC) and it can also be a hydraulic binder such. B. contain cement according to its Hardening of the ceramic mass gives a special strength.
- the integrated body acts in the composite body of the invention Grating as reinforcement for the heat-resistant ceramic mass, that on the wear-stressed side of the from the invention Composite body segments composed Component should lie, so on the segmented cyclone immersion tube Dip tube outside that of the inflowing into the cyclone Hot gas solid suspension is highly stressed.
- the drawing shows a section of the cross section through an inventive Composite body installation element or segment, consisting from a heat-resistant metallic base body 10, namely from a thin-walled z. B. 5 to 15 mm thick rolled steel material, on which the webs 11 with a metallic grate grid-shaped openings are tacked or welded. It would be also possible in the manufacture of the composite body, the grating 11 place loosely on the base body 10.
- the openings of the grate 11, viewed in plan, square, hexagonal or otherwise as polygonal or round, are with a high heat resistant Ceramic mass 12 filled in the lattice openings poured, shaken and then hardened.
- Coating 13 has the lowest possible porosity, especially one Glaze, glazing, enamelling etc.
- the thickness of the ceramic mass 12 can e.g. B. 25 mm.
- the metallic base body 10 no longer needs a heat-resistant cast, the thickness of which is large long segments are approximately more than 15 mm should. Rather, with the structure according to the invention heat-resistant and wear-resistant composite segments manufacture with a length of more than 120 cm without the Thickness of the metallic base body 10 must exceed 15 mm.
- the composite body segments become thermally and mechanically highly stressed dip tube of a cyclone of the cyclone suspended gas heat exchanger system / precalcination system a cement clinker burning plant assembled, so the heat-resistant Ceramic mass 12 on the outside of the metallic base body 10 arranged, that is the side on which the inflowing abrasive hot gas / solid suspension flows in. It exists but also the possibility of the layer structure of the invention Composite body on both sides of the base metal sheet 10 to arrange. In any case, the service life of the invention Composite installation elements or segments high.
- the metallic base body 10 consists of cast steel, can the metallic grid-shaped grate with its webs 11 completely or partially as a one-piece cast body together with the Base body 10 be made.
- the composite bodies according to the invention are not used for production segmented cyclone immersion pipes in cement clinker burning plants too to protect others a high thermochemical and abrasive Components subject to wear can be used, in particular for Protection of those built into the hot gas pipes and hot meal pipes Guiding and / or regulating elements such as swiveling diverter flaps, Impact slider or the like.
