Embodiment 1

[0050] This embodiment provides a method for preparing a metal composite panel, such as figure 1 As shown, the method includes the following steps:

[0051] Step 110, treating the oxide scale on the surface of the first slab and the second slab, and roughening the interface to be combined of the first slab and the interface to be combined of the second slab.

[0052] In this step, the first slab is placed on the first roller table, the first roller table is provided with a first brush roller and a first sealing groove, and the first slab is brushed off by using the first brush roller and the first sealing groove. The oxide scale of the interface to be compounded of the first slab, and roughening the interface to be compounded of the first slab.

[0053] The second slab is placed on the second roller table, the second roller table is provided with a second brush roller and a second sealing groove, and the second brush roller and the second sealing groove are used to brush off ...

Embodiment 2

[0068] Corresponding to Embodiment 1, this embodiment also provides a device for preparing a metal plate, such as figure 2 As shown, the device includes: a first roller table 1, a first brush roller 2, a first sealed water tank 3, a second roller table 4, a second brush roller 5, a second sealed water tank 6, a billet inlet guide roller 7, Preheating furnace 8, heating furnace 9, reduction furnace 10, high-temperature multi-head press 11, heater 12, high-pressure water dephosphorization machine 13, rolling mill entrance guide roller 14, rolling mill 15; among them,

[0069] The first roller table 1 is provided with a first brush roller 2 and a first sealing groove 3. When the first slab runs on the first roller table 1, the first brush roller 2 and the first A sealing groove 3 is used for brushing off the iron scale on the interface of the first slab to be compounded, and roughening the interface of the first slab to be compounded. The first brush roll 2 includes two.

Abstract

The invention discloses a method and device for preparing a metal composite board. The method comprises the steps of processing oxide scale of interfaces to be composited of a first slab and a second slab, and matting the interfaces to be composited of the first slab and the second slab; overlapping the first slab and the second slab; preheating the first slab and the second slab to 200 DEG C, then heating to 800 to 850 DEG C; reducing the oxide scale on the surfaces of the first slab and the second slab by using reducing gas with the concentration of 5% to 20% and temperature of 600 to 950 DEG C for 15 to 20 minutes, and the reducing temperature is not less than 800 DEG C; heating the overlapped first slab and second slab to 950 to 1300 DEG C and at the same time applying pressing force not greater than 20,000N to press the first slab and the second slab for 15 to 20 minutes to form a slab to be composited; performing descaling and multiple times of rolling on the slab to be composited to form the composite slab, and cooling the composite slab to form the metal composite board. In such a way, the oxide scale on the surface of the slabs to be composited is reduced by using the reducing gas, and the production efficiency is improved while the influence of oxides on the composite interfaces is eliminated.

Description

technical field [0001] The invention belongs to the technical field of iron and steel smelting, and in particular relates to a method and a device for preparing a metal composite plate. Background technique [0002] The metal composite panel is a new type of material compounded by two or more different metal materials through a special process. Compared with single metal components, metal composite panels after rational design and combination combine the respective advantages of metal components, and can obtain mechanical, physical and chemical properties that single metals do not have. At present, metal composite panels have been widely used in aerospace, petroleum, chemical industry, metallurgy, machinery, automobiles, ships, construction and other fields. [0003] Due to the large performance difference between the materials of the metal composite panel, the preparation of the metal composite panel has certain difficulties. The current preparation methods mainly include...
