Abstract
The utility model discloses a ceramic lined large diameter steel straight pipe, which belongs to the technical field of metal processing and manufacturing technology, and is adaptive to relative industries such as electric power, metallurgy, mines, coal, chemical industry, etc. for conveying grinding particle materials and corrosive mediums such as sandstones, powdered coals, ash slag, aluminum liquid, etc. The utility model is composed of a steel pipe, a steel layer inner wall, a transition layer and a ceramic coating, and is characterized in that the transition layer appressed with the inner wall of the steel pipe is also pasted with the ceramic coating. The utility model has the advantages of strong abrasion resistance, corrosion resistance, high temperature resistance, high heat resistance and anti-mechanical performance, smooth inside of the pipe, no scale, convenient installation, low cost, firmness, durability and long service life.
Description
Affiliated technical field
The utility model relates to a kind of large-diameter steel straight tube, relate to a kind of lined ceramics large-diameter steel straight tube specifically, belong to metal manufacturing technical field, be widely used in industries such as electric power, metallurgy, mine, coal, chemical industry, grindability granule materials such as sandstone, coal dust, lime-ash, aluminium liquid and Korrosionsmedium etc. are required as carrying.
Background technique
Before the utility model, in industries such as metallurgy high furnace, the defeated coal dust of electric power, the defeated powder in mine and coal washing, the general diameter of using of pipeline is small-bore steel straight tube below Φ 600mm all, its type is diabase lining pipe, rare earth wear-resistant steel pipe, line with rubber pipe etc., but above-mentioned a few class steel straight tube exposes serious deficiency and defective, drawback and shortcoming that it is main are: diabase lining pipe wear resistance is general, this lining wall thickness is big, usually mostly more than 35mm, its inner tube wall serves as a contrast has only about 15% to be the aluminium sesquioxide pottery in the attached composition, major part is SiO
2, SiO
2Mohs hardness is 6 grades, so anti-mechanical impact property is relatively poor; Rare earth wear-resistant steel pipe wear-resisting property is general, but the welding difficulty is big, and linear load is heavy, the engineering cost height, and the pipeline burst phenomenon often appears, working life is short; Line with rubber pipe non-refractory, easily aging, wear resistance belongs to general situation, and such steel pipe gum cover bulk integral body very easily occurs and peel off, thus blocking pipe, for the normal operation procedure of producing has brought " bottleneck " phenomenon.From the above mentioned drawback situation and phenomenon cause cost of production to improve for the relevant industries of using this type of steel straight tube, the serious waste resource, and the continuous operation that influence is produced is for industrial development has sustainably brought obstruction and greater loss.
Summary of the invention:
The objective of the invention is to provide a kind of novel lined ceramics large-diameter steel straight tube, to solve deficiency and the defective in the above-mentioned technology.
The technological scheme that its technical problem that solves the utility model adopts is: this structure comprises steel pipe, steel pipe inwall, transition layer and ceramic layer, and described steel pipe inwall is close to transition layer, and transition layer is close to ceramic layer.Forming process is such: aluminium powder and ferric oxide in the steel pipe of packing into, under the situation of steel pipe high speed rotating, produced powerful centrifugal force, pass through action of centrifugal force, aluminium powder and ferric oxide are got rid of to be attached on the steel pipe inwall, light ferric oxide this moment, the two at high temperature reacts, molten is aqueous body, when the steel pipe combustion process finishes, its the two response procedures also stops thereupon, on the steel pipe inwall, cool off to the greatest extent, solidify, tensile stress (also claiming thermal expansion force) that the steel pipe behind the expanded by heating produces and the pressure stress that reaction mass produced on the steel pipe inwall, the two unity of opposites forms the integral body of a balance, when the reaction mass cooling, also with its cooling cooling, at this moment steel pipe produces a kind of powerful compressive stress to steel pipe, and moment attaches to transition layer (ferroaluminium) and ceramic layer (aluminium sesquioxide) on the steel pipe inwall from spreading the rail journey by centrifugal, the steel pipe layer has appearred, transition layer, the whole machine balancing form that the ceramic layer three is not molten has mutually mutually just realized the purpose of design this moment.
Diameter of steel tube of the present utility model is Φ 600mm～Φ 1500mm.
The beneficial effects of the utility model are: design science is reasonable, technology is unique novel, simple in structure, manufactures conveniently, have anti-strong wearing and tearing, be able to bear strong corrosion, high temperature resistant, heat resistanceheat resistant and outstanding advantages such as mechanical shock resistance is strong, machinability and good weldability, smooth, the smooth non-scaling of this internal surface in addition, operation is fast in it, steadily resistance is little, and installation is convenient, cost reduces greatly, sturdy and durable, long service life is so there is very high practical and popularizing value.By retrieval, do not find as yet at present state, inside and outside have identical or the similar techniques feature with the present invention.Description of drawings
