Description
Technical field
The utility model relates to technical field of smelting, particularly a kind of in the pyrometallurgy environment liquid state metal meet and to become solid for cold time and be bonded at high-temperature adhesion resistant material coating on the equipment.
Background technology
The smelting iron and steel temperature is generally about 1600, so material should work in this temperature range, antiseized mainly is to solve the waste residue that produces in metal chance condensation knot and the metallurgical process to be bonded on equipment or the mould, in metallurgical smelting process because Metal smelting high-temperature technology liquid and generation in production technique have a lot of waste residues, be easy to meet cold become solid-state, bonding plucking on the equipment, be difficult to remove, accumulation affects the production technique operation, and serious can affect production efficiency and quality product.Since hot environment, workman's manual handling difficulty, and also relatively more dangerous, be a worldwide technique difficult problem.For example: metallurgical furnace, temperature 1600 degree in the stove, molten steel position liquid, metallurgical equipment is the refractory materials body of heater that box hat coats, the oxygen blast heating in smelting process when molten steel in the stove and slag when seething with excitement body of heater, is condensed at oxygen blast oxygen rifle and steel furnace shell, be difficult to remove, adopt high-temperature adhesion resistant material coating technology can effectively solve the metal sticking problem.
My former utility model adopt the lubricant of metallic cover sprayed on the metal object with supersonic spray coating and plasma spraying method with the metal bonding agent, can be effectively anti-1000 degree high-temperature adhesion resistants, to since the metal-to-metal adhesive ability be metal, high temperature resistant limited, can only be anti-1100 degree temperature, non-refractory affects frequency of utilization and environment for use.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of high-temperature adhesion resistant material coating is provided, this high-temperature adhesion resistant material coating manufacturing process is simple, application method is flexible, the high temperature that adapts to 1600 degree, having prevented effectively in the metallurgy environment that the liquid state metal is met becomes solid cold time and is bonded on the equipment, is widely used, safe and reliable.
In order to achieve the above object, the technical scheme that the utility model provides is: a kind of high-temperature adhesion resistant material coating has self-lubricating material particle, coating material and high-temperature-resistant adhesive; The particle diameter of self-lubricating material particle is micron order; Coating material coats described self-lubricating material particle; The fusing point of high-temperature-resistant adhesive is higher than the fusing point of described coating material, forms the high-temperature adhesion resistant material coating with coating good self-lubricating material particle bond together, is sprayed on the equipment that needs protection;

Coating material be metal or for the pottery or for alloy is the metals such as nickel, copper, aluminium, the potteries such as aluminum oxide, phosphoric acid salt, rare earth material; The thickness of the coating layer that coating material forms is far smaller than the particle diameter of self-lubricating material particle, and is easily broken;
High-temperature-resistant adhesive is aluminium dihydrogen phosphate;
High-temperature adhesion resistant material coating slave unit surface is to the surface of coating, and the ratio that coats good self-lubricating material particle increases gradually.
Surfaceness need to the solvent cleaning method of polishing, be improved in the surface of the equipment that needs protection.
The utility model high-temperature adhesion resistant material coating with the self-lubricating material granulation, can not wait from the nano level to the micron order according to different needs particle diameters.Self-lubricating material comprises boron nitride, the materials such as graphite, Calcium Fluoride (Fluorspan), barium fluoride, chromium sesquioxide, silver.
Coat lubricant, according to the performance of anti-stick coating, adopt refractory metal or nonmetally coat or not exclusively coat lubricant fully, coating thickness is nanometer or several microns.Manufacture breakable composite material granular.Can adopt chemical deposition or physics to coat method.Breakable composite material granular and self-lubricating material are compared itself, and good vacuum antioxidant property and process industrial art performance are arranged.
Metallurgical equipment (metal or nonmetal all can) surface treatment is clean.Adopt sand-blast, or with the solvent cleaning method of polishing.Improve surfaceness.
According to different metallurgical equipments, adopt aluminium dihydrogen phosphate and the metallurgical equipment body of different performance bonding, it has the very wide coefficient of expansion.Have high combination powerful with the metallurgical equipment matrix, thermal shock resistance is good.
Take aluminium dihydrogen phosphate as tackiness agent, with breakable composite material granular.Bond together, aluminium dihydrogen phosphate plays several effects, a) breakable composite material granular is coated again, because the resistance to elevated temperatures of aluminium dihydrogen phosphate self, the breakable composite material granular that again coats has played high temperature resistant vacuum antioxygenation, prevents the self-lubricating material oxygenolysis, b) bonding effect, breakable composite material granular is bonded together, played skeleton function.
High temperature resistant aluminium dihydrogen phosphate in varing proportions and breakable composite material granular.Make mixing material, the metallurgical equipment body is to skin, and the ratio of breakable composite material granular progressively increases.Then spary several times produces the material coating of the high-temperature adhesion resistant that bonding brute force from inside to outside descends gradually.Make the material coating of high-temperature adhesion resistant that the gradually layering fragmentation of coating that the outside can be arranged in the situation of external force arranged,
Breakable composite material granular is under the effect of external force or dirt settling self gravitation, and outer wall breaks, and the self-lubricating material of the inside discharges, and plays antiseized effect within the regular hour.Because the relatively gradually reduction of the inside of the brute force of coating outside, the unlikely coating integral body that makes comes off because of external force so that from outside to inside successively fragmentation of coating consumes, thereby guarantees high temperature resistant anti-stick coating according to different metallurgical equipment performances, and arranged very long work-ing life.
Except the breakable composite material granular of high temperature resistant aluminium dihydrogen phosphate of different ratios, can also add other high temperature self-lubricating composites of part at outermost layer, such as Calcium Fluoride (Fluorspan), the materials such as barium fluoride are the surface lubrication raisings.
High temperature resistant aluminium dihydrogen phosphate and breakable composite material granular solidify at 90 degree, and 150 kilsyth basalt face passivation form the high temperature resistance material, thereby make again low-temperature curing of high temperature resistant anti-stick coating, the processing performance of the excellence of applied at elevated temperature.
High temperature resistant anti-stick coating makes metallurgical equipment or mould antiseized metal or other metallurgical material in some cycles, make metallurgical equipment or die surface cleaning, solved and got bonding problem in the metallurgical production process, the steel bonding problem of steelmaking oxygen blowing oxygen rifle particularly, avoided cleaning time, saved because the repair time is repaired in the bonding shut-down that causes of equipment, improved production efficiency.Because steel adhesion on oxygen lance reaches several meters height, the workman is very difficult when processing the oxygen rifle of steel bonding, the slag of several meters height also danger close that falls down, high temperature resistant anti-stick coating have also solved because workman's working conditions that manual handling steel bonding oxygen rifle causes is abominable and the work safety problem.
