A kind of nonmetallic cooling stave, comprise water-cooled tube, the cooling stave that constitutes separately by the cold junction body, or contain the cooling stave that the cool and heat ends body is combined into, no matter be the cooling stave that the cold junction body constitutes separately, or the cooling stave that is combined into by the cool and heat ends body, all be to make with non-metallic material, convex-concave coupling pattern structure is arranged on the bonding surface of cool and heat ends body, and its hot side was horizontal bar connected in star or raised line when the cold junction body constituted cooling stave separately, or was the light face.
Described nonmetallic cooling stave, the pattern structure of convex-concave coupling is on the hot side of cold junction body, horizontal strip raised line or horizontal strip breast convex raised line is arranged, or have horizontal strip rectangular recess or horizontal strip breast convex groove on the cold junction body hot side, on the huyashi-chuuka (cold chinese-style noodles) of hot junction body, have the horizontal strip rectangular recess or the horizontal strip breast convex groove that match, or hot junction body huyashi-chuuka (cold chinese-style noodles) is provided with horizontal strip rectangle raised line or the horizontal strip breast convex raised line that matches.
Described nonmetallic cooling stave, when constituting cooling stave by described cold junction body separately, water-cooled tube directly is embedded in the cold junction body, when being combined into cooling stave by described cool and heat ends body, water-cooled tube is embedded in the cold junction body, the hot junction body is described cold junction body material, or makes for one or more non-basic refractories, for monoblock type cooperates with the cold junction body by the convex-concave matching structure; Or for the non-basic refractory goods assembling combination of hot junction body by some amount forms and cold junction body coupling, water-cooled tube is a serpentine tube, and alternate arc convex is arranged on the water pipe surface, and this external surface of cold junction is extended with and installs and fixes built-in connection, seat.
Useful positively effect of the present invention:
(1) refractoriness under load of nonmetallic cooling stave cold junction body of the present invention is greater than 1600 ℃, the fusing point of the spheroidal graphite cast iron that adopts than existing blast furnace cooling stave, steel, copper is much higher, make the cooling stave body have good high-temperature adaptability, improve nonmetallic cooling stave resistance to wearing under the condition of high temperature, erosion resistibility and chemical resistance of concrete ability, prolonged cooling stave work-ing life.
(2) in nonmetal body material, use materials such as SiC, C, zirconium white, silicon, aluminium micro mist, make the cooling stave of cast, ramming process that better anti-slag, iron and basic metal erosional competency be arranged, improve wearing quality.
(3) the non-metallic material coefficient of thermal expansion of formation cooling stave cold junction body is little, cooling water circulation like this water pipe can be directly and the furnace shell welding, the inhomogeneous heat expansion that has overcome between existing metal cools wall body and the furnace shell causes the water pipe rupture failure, simplified the complex construction of avoiding water pipe to absorb differential expansion and sealing, nonmetallic cooling stave material heat expansion rate is little, can not occur the phenomenon of metallic substance crack propagation such as cast iron, steel in the use.
(4) the hot junction body adopts and to burn till refractory brick and have than cast, ramming and give clamp dog better intensity, higher compactness and use temperature, in blast furnace is gone into operation the back quite a long time, better protects the cold junction body, opposing machinery, chemical erosion.After work for some time; when burning till refractory brick and be etched totally; be embedded in the effect that the remaining refractory brick performance slag crust in the cold junction body adheres to fulcrum, help the cold junction hot side and generate stable " slag crust " protective layer, obtain to prolong the effect in cooling stave life-span.
(5) the hot junction body can adopt the refractory product of one or more materials to constitute, and makes the present invention can use the different working conditions at position according to difference, selects differing materials, reaches the best effect of making the best use of everything.
(6) its comprehensive cost of nonmetallic cooling stave reduces more than 50% than the facility investment of metal matter cooling stave, the non-metallic material wide material sources, and domestic aboundresources has application promise in clinical practice.
