Description
Technical field
The present invention relates to a kind of manufacturing approach of clad steel, belong to metal material and make the field.
Background technology
Clad steel is owing to have good: advantages such as anti-wear performance, drawability, hardness, toughness; Be applied to industry and civilian every field; As: building, chemical machinery, storing, electric power etc.; Present domestic manufacturing clad steel roughly is divided into: traditional forging method, explosive forming method and casting composite algorithm.Traditional forging method is to be heated to uniform temperature to two kinds of steel, forges with pressure hammer, makes it to integrate the method that is rolled then.This method is because the time that forges and the bad grasp of number of times of the temperature and pressure of two kinds of steel hammer; So two kinds of steel gas enclosures, the folder ash is many, and needs post bake when rolling; Make the steel decarburization easily; Cause required steel carbon-content to descend, cycling processability is poor, and the clad steel that this method is produced is a qualification rate or all very poor in processing characteristics.The explosive forming method is the solid phase composite algorithm, and its characteristics are suitable for the metal seam that large tracts of land is compound and fusing point differs greatly of two kinds of metals.But not enough is: adopt the explosive forming method, the impulsive force during because of explosive charge is uppity, therefore causes the metal composite interface that gas enclosure is arranged, and presss from both sides grey phenomenon, causes unstable product quality, and production cost is high.Adopt the explosive forming method also to exist explosive to deposit and the explosion place selection simultaneously, noise treatment, safety guarantee and a series of problems such as seriously polluted.
The casting composite algorithm is liquid-solid mutually compound, is that required steel are placed punching block, and is compound with required steel in the matrix molten steel injection punching block with fusion, processes clad steel with hot rolling again.But different because of composition metal with the fusing point of matrix steel, when casting, be prone on the one hand make the binding site of two kinds of metals produce melting loss, compound interface is prone to take place oxidative phenomena; On the other hand; Two kinds of metals are when at high temperature fusion is compound, cause carbon atom in the high-carbon steel tempestuously to the diffusion of mild steel side, cause required steel carbon containing to descend; Secondly there is gas enclosure too in the liquid-solid compound interface that is compounded in mutually; Folder ash and poor in processability once more, combination of materials size and steel are not higher than accuracy, a series of problems such as homogeneity difference.Therefore be difficult to produce the clad steel of high-quality, moreover adopt liquid-solid mutually compound manufacturing process relative complex.
Summary of the invention
The manufacturing approach that the purpose of this invention is to provide a kind of clad steel, this clad steel can make metal interface bonding firmly, stable after the high temperature hot rolling; Its material section combination size is compared with the clad steel that additive method is processed; Accuracy is high, and yield rate is high, does not reduce the mechanical performance of required steel.
For realizing the object of the invention, the present invention provides a kind of manufacturing approach of clad steel, and it may further comprise the steps:
1) steel plate and matrix steel are smoothed, the faying face of required steel plate and matrix steel is carried out the deoxidation layer, abatement processes makes faying face bright and clean, and is smooth;
2) steel plate and matrix steel are stacked, the contact area of the faying face of required steel plate and matrix steel must reach 100%, and making does not have air between the faying face; Then the 90%-100% of the girth seam total length of faying face is carried out seam and fix, process blank;
3) above-mentioned blank is heated to 950-1000 ℃ in stove, kept 20-30 minute, after getting into hot-rolling mill again and being rolled, handle, process clad steel of the present invention by the conventional method stress relief annealing.
Preferably, the seam length around the faying face being carried out 100% totally-enclosed seam fixes.
Preferably, said clad steel is one deck steel plate one deck matrix steel or two-layer matrix steel therebetween one deck steel plate or two-layered steel plates therebetween one deck matrix steel.
More preferably, in the middle of the faying face of required steel plate and matrix steel, can also be covered with the nickel foil or the Copper Foil of the equal size of one deck area.
Described steel plate comprises: carbon steel, steel alloy.
Described matrix steel is a wrought iron.
The present invention at first smooths required steel and matrix steel and polishes, and makes it bright and clean, and is smooth; After two kinds of metals stacked, no air got into, and carries out seam at the contact-making surface girth seam again and fixes; Realized non-oxidation manufacturing in the recombination process; Heating-up temperature and heat time heating time through the control blank are activated two or more intrametallic atoms and spread each other, under the high pressure of hot-rolling mill external force; Thereby in the extremely short time, accomplish intermetallic combination, realized that the solid phase of two kinds of metals is compound.
The manufacturing approach of a kind of clad steel of the present invention i.e. (solid phase composite algorithm), owing to can avoid high temperature that the melting loss and the carbon atom in the high-carbon steel of the faying face generation of two kinds of metals are spread to mild steel side tempestuously with respect to the casting composite algorithm, and in the mechanical performance that keeps high-carbon steel; Because the compound interface anaerobic gasification of two kinds of metals; And compound interface does not have gas enclosure, presss from both sides grey phenomenon, and forms firm linkage interface; Make combination interface stable, and good cycling processability is arranged.
The present invention adopts the solid phase composite algorithm, and the combination size of clad steel and steel are than simplicity of design, accurately; Material range is wide, and manufacturing process is simple, is easy to suitability for industrialized production; Yield rate is high, owing to realized non-oxidation manufacturing in the recombination process, can make the yield rate of clad steel reach 100%; Blank of the present invention can be placed for a long time, and does not influence the character of clad steel.The present invention had both guaranteed the high combined strength bination of clad steel, had kept the original mechanical performance of two kinds of metals again, had really realized the best-of-breed technology of production high-quality clad steel.
