Description

Nonmetallic cooling stave
(1) technical field: the utility model relates to but wall of a kind of blast furnace cold, particularly relates to a kind of nonmetallic cooling stave.
(2) background technology:, two types of metal cools wall and nonmetallic cooling staves are arranged at present as blast furnace cooling stave.In the metal cools wall, be divided into cast-iron cooling wall again, three kinds of steel cooling wall and copper cooling walls.Cast-iron cooling wall adopts spheroidal graphite cast iron or other cast iron as the material of cooling stave body, when cast, gives and imbeds circulation cooling steel water pipe, forms the flow of cooling water passage.The advantage of cast-iron cooling wall is that cost is lower, but heat conductivility is bad, cooling performance is relatively poor, the steel water pipe exists carburizing and water pipe surface melting phenomenon when cast simultaneously, there is high thermal resistance gap between steel water pipe and cast iron body, defectives such as body material metal toughness difference in use are prone to corrode, crackle, and the life-span is shorter; Steel cooling wall adopts cast steel or rolled sheet material as cooling stave body material, by be cast into the molten steel pipe or in rolled sheet material the bore hole mode, in the cooling stave body, form the flow of cooling water passage.The steel cooling wall material has better toughness, and material melting point is than advantages such as height, and heat conductivility is still lower, the defectives such as melting phenomenon when having the water pipe surface casting equally; Its over-all properties of copper cooling wall is better, and heat conductivility is good, but is worth highly, and many iron and steel enterprises are subjected to economics dictate, can't adopt; CN1259579A discloses a kind of nonmetal cooling apparatus of monomer that is applicable to blast furnace, the body material of this nonmetallic cooling stave is by corundum, silicon carbide, silica flour and wooden calcium sulfonate, aluminium dihydrogen phosphate combines, this blast furnace cooling apparatus (cooling stave) cost is lower, certain advantage is arranged, but water-cooled tube glide path in the cooling stave body is shorter, make cooling performance not ideal, and cause the outer water pipe of last furnace shell to connect complicated, in manufacturing process after the moulding of monomer cooling apparatus matrix, carry out nitrogenize and burn till, cause cost to increase by a relatively large margin, matrix thickness is bigger simultaneously, it is complete to be difficult for nitrogenize, makes material structure, there is defective in performance.
(3) utility model content: the purpose of this utility model is, overcomes the deficiency in the background technology, prolongs the cooling stave life-span, reduces cost, develops nonmetallic cooling stave.
The technical solution of the utility model is: a kind of nonmetallic cooling stave, comprise water-cooled tube, the cooling stave that constitutes separately by the cold junction body, or the cooling stave that is combined into by the cool and heat ends body, when the cold junction body constitutes cooling stave separately, its hot side has horizontal bar connected in star or raised line, or is the light face, and concavo-convex coupling pattern structure is arranged on cool and heat ends body bonding surface.
The pattern structure of convex-concave coupling can be on the hot side of cold junction body, horizontal strip rectangle raised line or horizontal strip mastoid process shape raised line are arranged, or have horizontal strip rectangular recess or horizontal strip mastoid process connected in star 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 mastoid process connected in star that match, or hot junction body huyashi-chuuka (cold chinese-style noodles) is provided with horizontal strip rectangle raised line or the horizontal strip mastoid process shape raised line that matches.
The cooling stave that constitutes separately by the cold junction body, or be combined into cooling stave by the cool and heat ends body, and all be that non-metallic material are made, the non-metallic material of cold junction body are prepared by a certain percentage by main body material and wedding agent material, the main body material is by corundum, silicon carbide, zirconium white, graphite, alumina powder, Pure Silicon Metal micro mist, metallic aluminium powder is mixed evenly by a certain percentage, the wedding agent material is by dextrin, phosphoric acid, and water is mixed by a certain percentage.
Water-cooled tube is embedded in the cold junction body, and water pipe is a serpentine tube, and outside surface has alternate arc convex, and this external surface of cold junction is extended with to install and fix to give and buries web member, seat.
The cool and heat ends body can use identical material or unlike material, and the hot junction body can use one or more non-basic refractories to make.
The hot junction body can be monoblock type and cooperates with the cold junction body by concavo-convex matching structure, or to be the hot junction body by the non-basic refractory goods assembling combination of some amount form with the cold junction body mates.Useful positively effect of the present utility model:
(1) refractoriness under load of nonmetallic cooling stave cold junction body of the present utility model 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.
