Manufacturing method of titanium-copper-stainless steel three-layer composite plate for pots

Abstract

The invention discloses a manufacturing method of a titanium-copper-stainless steel three-layer composite plate for pots. The manufacturing method comprises the following steps: (1) polishing contact surfaces of a titanium plate, a copper plate and a stainless steel plate, and brushing the outer surfaces of the plates with a separating agent; (2) polishing one surfaces, contact with the three-layer laminated plate, of two steel plates, welding a side plate to a polished surface of one steel plate, and forming an exhausting pipe hole; (3) putting the three-layer laminated plate on the steel plate, and buckling the two steel plates so as to form a closed space between the side plate and the steel plates; (4) pressing and flattening the five-layer combined blank, and sequentially carrying out spot welding fixation and electric welding to seal peripheral gaps; (5) vacuumizing the combined blank by virtue of the exhausting pipe hole to maintain the five-layer combined blank at a vacuum state, so as to obtain a vacuum plate blank; (6) heating the vacuum plate blank, and carrying out calendering compositing by virtue of a hot mill; (7) heating the calendering composite plate, so as to eliminate stress in air; and (8) separating the steel plates, so as to obtain the composite plate.

Description

technical field [0001] The invention relates to a method for manufacturing a composite board, in particular to a method for manufacturing a titanium-copper-stainless steel three-layer composite board for pots. Background technique [0002] Pots are utensils for cooking food. They are made of metal materials, mostly made of metal plates. Metal materials for pots require high strength, good thermal conductivity, high temperature resistance, corrosion resistance, beautiful appearance, and will not affect the human body. healthy substance. At present, iron, aluminum, and stainless steel are widely used as cooking utensil materials at home and abroad, and these materials will more or less cause some unfavorable factors to people's health in the use of cooking utensils. The advantage of iron pan is that the material price is low, the manufacturing cost is low, cooking with iron pan can supplement iron, the disadvantage is that the corrosion resistance is poor, and it is easy to r...

Problems solved by technology

In the existing three-layer metal composite technology, there are titanium-aluminum-stainless steel composite panels manufactured by hot pressing equipment, which are only fixed by a press and then heated and pressed. In addition, the existing titanium steel aluminum manufacturing method, aluminum is a composite slab obtained by scraping the prepared aluminum powder paste on the steel surface, the disadvantage is that the uniformity of the aluminum powder paste is difficult to grasp, And the sealing method is to apply sodium hydroxide on the periphery of the fusion seal to obtain an edge-sealing laminated board. This process is complicated and has many uncontrollable factors, so it is not suitable for large-scale production
