Abstract
The invention relates to a manufacture technique for improving the wearing resistance of an extrusion forming mould material, and the manufacture technique can be applied to the industries such as a building material and a flame-proof material which need the extrusion forming mould. The manufacture technique aims to manufacture a ceramics iron and steel composite board, so as to improve the rigidity of the key place of the mould and strengthen the wearing resistance of the mould through cutting, inserting and welding the board to the extrusion mould. The manufacture technique mainly adopts the technical proposal that: with vibration and magnetic force, the separation problem of the thermit reaction liquid product of Fe and Al2O3 in self-spreading ceramics iron and steel composite manufacturing is solved, so as to reach the equal effect for separating the rotation inertia force. The main element of the mould comprises a flame-proof material box provided with the steel plate backing as the base, and reaction raw material Al as well as Fe2O3 mixed-powder which are filled-in at the upper opening of the flame-proof material box; one end of a steel mobile stage is fixedly provided with a speed-regulation vibration electric motor with eccentric quality, and the middle part of the steel mobile stage corresponding to the steel plate backing is punched with for fixing a permanent high magnet; the upper side of the magnet is parallel to the surface of a platform; the platform is connected with the base through a rolling bearing and a spring.
Description
Technical field:
The invention belongs to the manufacturing technology that improves the extrusion molding dies material wear ability.The industry that can be used for a large amount of extrusion molding dies of needs such as construction material, refractory material, semisolid Metal Processing.
Background technology:
In the construction material moulding, the refractory material moulding, mould is main production equipment in the industry extrusion modlings such as semisolid Metal Processing, their common trait is that material is big especially to the friction of mould in the extrusion modling engineering, die wear speed is fast, the mould and die accuracy life-span is short, for head it off, expert and engineers and technicians develop multiple high rigidity, wear-resisting high-carbon, Gao Ge, Gao Meng, steel alloys such as high molybdenum are as the mould manufactured materials, perhaps existing steel alloy mould is carried out carburizing, nitriding, technology such as carburized tungsten improve its anti-wear performance, good effect is all arranged, at construction material, be used widely in the mould production of refractory material extrusion modling, but its shortcoming is a die cost to be improved greatly, spread out die cost on every manufactured goods also than higher, under the condition of fierce competitive market, reducing die cost also is a practical way.
On the other hand, ripe (ZL method for preparing thin-wall steel pipe with ceramic lining, University of Science ﹠ Technology, Beijing, China, C04B35/65,200510086804.9 of ceramic iron and steel multiple tube manufacturing technology; The manufacture method of ZL composite pipe with ceramic lining, Wang Jianjiang, China, B28B21/72,97111352.1).The pottery steel pipe be adopt self propagating high temperature synthetic-centrifugal process makes.Exactly seamless steel pipe is placed in the pipe die of centrifuge, adds iron oxide red and al powder mixt in the steel pipe.This mixture is called thermite in chemistry.After the rotation of centrifuge pipe die reaches certain speed, light thermite, thermite burns immediately, and following violent chemical reaction takes place when spreading the combustion wave rapid spread:
2Al+Fe
2O
3＝Al
2O
3+2Fe+836kJ
3Fe
3O
4+8Al＝4Al
2O
3+9Fe+3265kJ
Product is α-Al behind this thermit reaction
2O
3(being corundum) and iron are emitted a large amount of heats simultaneously.These heats are as under in adiabatic condition, and adiabatic temperature can reach 3753K and 3509K, and it makes in the steel pipe original material and reacted product corundum all become liquation, because reaction is very fast, have only the several seconds, the frit reaction thing separates by the proportion size rapidly under centrifugal action.Iron is thrown to steel pipe inwall, Al by centrifugal force
2O
3Then be distributed in the internal layer of iron.Because steel pipe is heat absorption and heat transfer rapidly, Al
2O
3Reach freezing point rapidly with Fe, very fast layering is solidified.At last the ceramic steel pipe of Xing Chenging be respectively the corundum enamel coating from inside to outside, based on the transition zone of iron and outside steel pipe layer.The iron liquid and the Al of high-temperature fusion
2O
3Liquid, contact with the steel pipe inwall, make steel pipe be in the semi-molten state, make iron layer and steel pipe form metallurgical binding, also form strong bonded between iron layer and diamond spar enamel coating, its mechanical endurance can improve greatly, measures through the authoritative department simulated test, resistance to wear the combination property of antiscour all than improving more than 5 times with the wear-resistant alloy cast steel of heavy wall, improve more than 20 times than No. 20 carbon steel pipes.
The static self-spreading legal system is equipped with ferrous metal semi-solid processing ceramic coat die (Chen Wei etc., application number: 200510040328.7; Authorization notification number: 1762618), in extrusion die production, obtained application, be characterized in that die is Integratively formed, but document is only found the example of succeeding at the circular die of simple shape, the extrusion die complicated slightly for the production shape also has great difficulty, furtherly, spreading legal system certainly, to be equipped with the technology difficulty of extrusion modling ceramic coat die bigger, is difficult to promote in general extrusion die manufacturing enterprise.
Summary of the invention
The invention reside in and utilize,, reach and improve mould key position hardness, strengthen the purpose of its wearability by cutting, inlay, be welded in the extrusion die from spreading manufactured pottery iron and steel composite board.
Major technique of the present invention is characterized as: finish under vibration and magnetic force environmental condition from spreading thermit reaction and liquid product Fe and Al in the compound manufacturing of method pottery iron and steel
