Description

A kind of big thickness bi-metal composite panel production equipment of large area

Technical field

The utility model relates to foundry engieering and field of new materials, especially a kind of big thickness ply-metal of large area Material production equipment.

Background technique

There are many bimetallic complex method at present, mainly there is roll-bonding method, explosion composite method, casting composite algorithm etc..

Rolling compund has that diffusion of alloy elements is insufficient and chemical reaction, bond strength still have deficiency, and Process is more, need to clear up raw material surface, and production efficiency is lower.Therefore there is the technology for combining casting with rolling, it is such as anti- To solidification, liquid, semisolid casting, liquid, liquid casting etc..Reverse solidification cannot generate the biggish material of matrix thickness, only It is suitble to production thin plate and band.Although solid-liquid casting and roll process does not have to preheated substrate and carries out coating and coating scaling powder etc. to matrix Surface treatment, but too thick metal plate cannot be produced, clad can not be too thick, and equipment is expensive, once puts into huge.

The working condition of explosive welding is poor, and obtained complex laminate out-of-flatness and production process have certain risk. Using casting production double metallic composite material, cost is relatively low, bond strength is high between metal, therefore have developed rapidly.Common is double Metal composite casting method has casting infiltration, inlays casting, double-fluid double metal composite casting method etc..Casting infiltration has very under study for action More problems are to be solved, such as slag inclusion, wash away, penetrating power is poor, alloying layer thickness is uneven and scab.The shortcomings that centrifugal casting is technique Process is cumbersome, and inner layer metal liquid has souring to outer layer when casting, and the interface of the clad pipe or roll prepared is also easy to produce one A little casting flaws.Continuous casting process production bimetallic plied timber research and application have become Metal coating investigation of materials field One of hot spot, research direction has at present: being continuously poured composite casting technique, double crystallizer continuously casting technologies, double fluid casting company Continuous foundry engieering, electromagnetic braking continuously casting technology etc..

Continuous casting composite casting is mainly used for the production of composite roll.The shortcomings that technique is that internal layer need to be located in advance Reason is then not easy to prepare the roll being well combined if treatment effect is not good enough, or do not cast at once after processing.

The Novelis Fusion technology of Novelis company can be realized big thickness ply-metal.But the technology pair Metal bath surface height has strict demand, and liquid level has to be lower than heat-exchanger rig bottom, but again cannot be excessive with distance from bottom, therefore needs It to be just able to achieve using advanced liquid surface height controlling system.

Existing solid-liquid complex technique there are the problem of include: that must overcome base metal surface oxidation film to compound obstruction Effect, need to just can be carried out substrate preheating to enough temperature compound, need to carry out recombination process under protective atmosphere.For this purpose, The prior art all needs the processing that a series of complex is carried out to matrix surface, carries out under gas shield after coating metal surface cleaning It is compound；The overlay coating or coating scaling powder of some technologies then after the cleaning；It needs to use heating equipment before compound or in recombination process Parent metal is heated.Increase process, production cycle and the cost of technique.

Currently, the development key of composition metal is: realizing metallurgical bonding between metal, meeting the premise of bond strength Under, seek the production method and equipment of simpler, economic and efficient disposal multi-layer and multiple types metal composite.

Utility model content

The purpose of this utility model is to provide a kind of big thickness bi-metal composite panel production equipments of large area, solve The problem of proposed in background technique.

To solve the above problems, the utility model provides the following technical solutions: a kind of big thickness bimetallic of large area is compound Board production equipment, including matrix and clad, the bottom of described matrix are equipped with mobile platform, and described matrix is set to heat preservation casting mold In, the top of the heat preservation casting mold is equipped with clearance type casting ladle, and the inside of the clearance type casting ladle is equipped with clad molten metal, described The left side for keeping the temperature casting mold is equipped with spoiler, and the bottom of the heat preservation casting mold is equipped with metal mold.

Compared with prior art, the beneficial effects of the utility model are as follows:

Processing cost is low.Since the running gate system of the utility model is directly contacted with plate, the plate tailing of formation Less, it can be achieved that near-net-shape, reduces machine-finish allowance, stock utilization is up to 90% or more, so processing cost is low.
