Description
Technical Field
The invention belongs to the field of materials, and particularly relates to a method for producing a titanium/aluminum/stainless steel composite sheet on a large scale.
Background
Titanium metal is almost inert to human body in physiology and is the only metal which has no effect on vegetative nerve and gustatory nerve of human body, so that the cookware made of titanium can ensure cooking safety, is corrosion-resistant and can be almost permanently used. However, titanium has poor thermal conductivity and poor heat storage function, is likely to cause temperature unevenness during heating, and cannot be used for electromagnetic heating. Therefore, the titanium pot produced at present adopts a titanium composite structure in material. Wherein, the inner layer contacting with food adopts pure titanium called biological metal, which avoids the separation of harmful heavy metals (such as manganese, nickel, chromium, etc.) in cooking and storing food; the middle layer is made of pure copper or aluminum, so that heat of the pan bottom is rapidly transferred to the pan edge, and oil smoke and food heating unevenness caused by overheating of the pan bottom are avoided; the outer layer is made of magnetic stainless steel, can be electromagnetically heated, is corrosion-resistant, is clean and easy to clean, and accordingly the function of the pot body is refined, and the best performance is achieved.
At present, the mainstream preparation methods of the composite board comprise a rolling composite method, an explosion composite-rolling method and an explosion welding method. The explosion cladding-rolling method and the explosion welding method are production processes of medium-thickness composite plates, and compared with other methods, the rolling cladding method has the advantages of good product quality stability, higher production efficiency, simple process and easy realization of industrial batch production, and is a main preparation method of future composite plates, particularly composite sheets for manufacturing pots. At present, the mainstream manufacturers in China still mainly produce the composite plates by an explosion method or an explosion and hot rolling method, the existing intellectual property rights are mainly focused on the aspects of explosion cladding and explosion and rolling cladding technology, and the titanium/aluminum composite thin plates or ultrathin plates are not involved.

Detailed Description
The technical solution of the present invention can be specifically implemented as follows.
The method for producing the titanium/aluminum/stainless steel composite sheet on a large scale specifically comprises the following steps:

Preferably, in the step b, the heating mode is to put the stacked plates into an air circulation furnace, an electric furnace or a continuous heating furnace for heating, the heating temperature is controlled to be 300-.
In order to ensure better annealing effect, it is preferable that in the step d, the annealing temperature is controlled to be 400-; the cooling mode is furnace cooling or air cooling; and cutting the head and the tail of the cooled composite plate to obtain the titanium/aluminum/stainless steel composite sheet.
