Problems solved by technology

When the cladding material is formed by hot-dip plating, the core material needs to be preheated to a certain high temperature in advance, and the core material will be immersed in the cladding metal melt for a long time. It is more likely to be excessively corroded, the thickness of the interface diffusion layer of the cladding material, the interface quality (such as easy to generate intermetallic compounds, etc.) and the thickness of the cladding layer metal are difficult to control, and the thickness uniformity and stability of the cladding layer metal are difficult to guarantee , the surface quality of the cladding layer metal is poor, and at the same time, the equipment is complicated, the investment is large, the technology is difficult, and the production cost is high
Some other composite casting methods are being developed that use the cladding metal melt to continuously clad the formed solid core material (such as horizontal continuous casting cladding, down-drawing continuous casting cladding, net-shape casting and rolling). C

Embodiment 1

[0038] The core material is a Q235 steel bar with a diameter of 15 mm, and a copper-clad steel composite bar with a thickness of 1 mm of pure copper in the cladding layer is formed by continuous casting.

[0039] Under air conditions, the heater (6) heats and insulates the cladding pure copper melt in the crucible (5) to 1200°C; during the continuous casting process, it is continuously filled into the core material protection device (3). Nitrogen; start the traction mechanism (11), so that the Q235 steel bar starts to move towards the dummy ingot through the core material guiding and positioning device (2) and the core material protection device (3), and at the same time, the side of the head end of the dummy bar (13) leaves position of the draft tube (7); then the cladding pure copper melt in the crucible (5) flows into the draft tube (7) from the bottom side of the crucible (5) into the reverse solidifier (9), and passes through the high-temperature cladding The contact betw...

Embodiment 2

[0041] The core material is a pure copper wire with a diameter of 2mm, and a silver-clad copper composite wire with a cladding layer of pure silver with a thickness of 0.2mm is formed by continuous casting.

[0042] Under the condition of argon gas protection, the clad pure silver melt in the crucible (5) is heated and kept warm to 1050°C by the heater (6); Fill in argon; start the traction mechanism (11), so that the core material pure copper wire passes through the core material guide and positioning device (2) and the core material protection device (3) and starts to move towards the direction of the dummy ingot, and at the same time the dummy rod (13) The side of the head end leaves the position of the draft tube (7); then the coated pure silver melt in the crucible (5) flows from the bottom side of the crucible (5) into the draft tube (7) and enters the reverse coagulator (9), Through the contact between the high-temperature clad pure silver melt and the unpreheated pure ...

Embodiment 3

[0044] The core material is a pure titanium pipe with a diameter of 6 mm and a wall thickness of 1 mm, and a copper-clad titanium composite pipe with a cladding layer of pure copper with a thickness of 1 mm.

[0045] Under the condition of argon gas protection, the cladding layer pure copper melt in the crucible (5) is heated and kept warm to 1150°C by the heater (6); during the continuous casting process, the core material protection device (3) and The pure titanium pipe is continuously filled with argon gas; the traction mechanism (11) is started, so that the core material pure titanium pipe passes through the core material guiding and positioning device (2) and the core material protection device (3) and begins to move toward the dummy The side of the head end of the ingot rod (13) leaves the position of the guide tube (7); then the clad pure copper melt in the crucible (5) flows from the bottom side of the crucible (5) into the guide tube (7) and enters the reverse solidifi...

Abstract

The invention discloses a clad material solid/liquid composite continuous-casting forming device and method and belongs to the technical field of clad material continuous casting. A core product protecting device, a guide pipe, a reverse coagulator and the like are installed on the side of a crucible, a core material is not heated in advance, the designed small-capacity reverse coagulator is used for preventing the core material from penetrating a cladding layer metal melt for a long period of time, the melt flows out of the side of the bottom of the crucible by relying on self weight, the sizes of the reverse coagulator and a water-cooling crystallizer are effectively regulated and controlled, and other measures are adopted, so that a high-quality clad material with required shape and size is formed through continuous casting. The clad material solid/liquid composite continuous-casting forming device is simple in structure, convenient to operate and maintain, reasonable and compact in layout, high in production efficiency, low in investment, short in forming process, energy-saving, environment-friendly, efficient and low in cost, parts are easy to replace, automatic control is easy to achieve, large-scale industrial production is facilitated, combination freedom degree of cladding layer metal and core material metal is high, and the prepared clad material is good in quality and performance.

Description

technical field [0001] The invention belongs to the technical field of continuous casting of coating materials, and in particular relates to a solid / liquid composite continuous casting forming equipment and method for coating materials. technical background [0002] The cladding material is a composite material that coats a layer of dissimilar metals on the core material. It has the advantages of both the cladding metal and the core material metal. It not only has excellent comprehensive performance, but also greatly reduces the amount of precious metals used and reduces the cost. Therefore, it is widely used in the fields of aerospace, energy and environmental protection, construction machinery, petrochemical industry, transportation, electronic information, national defense and military industry, and daily life. It is a key development direction of composite materials at present. [0003] The traditional cladding material forming methods mainly include core material surfac...
