Embodiment Construction

[0018] Figure 1, figure 2 , shown in Fig. 3, the manufacturing device of large-scale bimetallic composite panel of the present invention, comprises machine base 1, induction heater 2, slit type insulation pouring device 3, retaining structure 4, conveying mechanism 5, vibrating mechanism 6 and insulation agent cover device7.

[0019] The base 1 includes a frame 11 and a sealed chamber 12 mounted on the frame 11 with sealing properties.

[0020] The airtight chamber 12 is made of heat-resistant glass or steel plate, and its size can ensure that the induction heater 2, the slot-type heat preservation pourer 3 and the heat preservation agent cover 7 are included, so that the preheated substrate 8 is melted in the casting cladding metal. Body and thermal insulation agent are not in contact with air before, when the protective gas is passed in the sealed chamber 12, an oxygen-free and atmosphere-protected environment is formed, which prevents the steel plate from being oxidized du...

Abstract

The invention discloses a method of producing large double metal composite plate and a device thereof. The method and device can continuously produce large-size thick double metal composite plates with high production efficiency, low cost, accurate control of interface layer and good lamination. The device comprises a frame with a sealed chamber, an induction heater arranged inside the sealed chamber, a gap-type heat-insulating caster and a conveying mechanism. The sealed chamber has an oxygen-free protective atmosphere inside. The method includes the following steps: substrate preparation, casting preparation, continuous hot casting, oscillatory crystallization and finishing. The continuous hot casting step includes: continuously heating a continuously forward-moving substrate by the induction heater and the gap-type heat-insulating caster in the oxygen-free protective atmosphere, allowing a molten metal coating for continuous casting to flow towards the substrate through a casting gate in a downward-oblique direction, and completely solidifying the molten metal coating on the substrate by means of oscillatory crystallization.

Description

technical field [0001] The invention relates to a manufacturing method and device of a layered board product, in particular to a manufacturing method and device of a large double-metal composite board. Background technique [0002] Bimetal composite panels are widely used in metallurgy, shipbuilding, aerospace, chemical industry, electric power, electronics, thermal engineering and other industrial fields. The common types are titanium / steel, copper / steel, nickel / steel, aluminum / steel, copper / aluminum, etc. category. In the prior art, the manufacturing methods of bimetal clad plates can be roughly divided into three categories: welding clad method, rolling clad method and casting clad method. [0003] Explosive welding is the simplest of the welding composite methods, and its composite interface is in good condition, but it is difficult to produce large-thickness bimetallic composite panels with a cladding thickness exceeding 20 mm, and the deformation during the forming pr...
