Description

A kind of composite metal

Technical field

The utility model relates to cook utensil and manufactures field, particularly relates to a kind of composite metal manufacturing cook utensil.

Background technology

The bottom of a pan of the prior art is normally made up of single-layer metal, such as stainless steel or carbon steel.Because the bottom of a pan is in the working environment of high temperature, many salt for a long time, the poisonous metal in the bottom of a pan can be caused after stainless steel or carbon steel material contact with food materials to separate out, and pollute food materials.The bottom of a pan of being simultaneously made up of single-layer metal can cause the bottom of a pan heat conduction uneven, thus sticky pot occurs or the phenomenon such as to be charred.

Utility model content

The purpose of this utility model is open a kind of composite metal, in order to improve heat conductivility and effectively to prevent poisonous metal from separating out.

For realizing above-mentioned utility model object, the utility model discloses a kind of composite metal, comprise titanium layer, the first aluminium lamination, layers of copper, the second aluminium lamination and stainless steel layer, the bottom of stainless steel layer offers blind hole.

In some embodiments, blind hole has multiple, is distributed in bottom described stainless steel layer.

In some embodiments, blind hole is conical blind hole, and the tapering of blind hole is 5-12 degree.

In some embodiments, the internal face of blind hole has multi-turn convex ridge.

In some embodiments, the thickness of titanium layer, the first aluminium lamination, layers of copper, the second aluminium lamination is equal, and is less than the thickness of stainless steel layer.

In some embodiments, the thickness of titanium layer, the first aluminium lamination, layers of copper, the second aluminium lamination is 1/6 of stainless steel layer thickness.

Compared with prior art, the beneficial effects of the utility model are: first, and titanium layer directly contacts with food materials, and the harmful metal elements avoided in stainless steel layer is separated out and polluted food materials; Secondly, by the first aluminium lamination, layers of copper and the second aluminium lamination that superpose, the excellent heat conductivity performance had by aluminium and copper, can further improve the heat transfer efficiency of composite metal, prevent hot-spot, effectively improve the heat conductivility of composite metal, prevent the problem that cooker sticky pot occurs or is charred; Finally, the multi-turn convex ridge had by the internal face of the blind hole offered in the bottom of stainless steel layer and blind hole, is increased the surface area contacted with thermal source, thus further increases the heat transfer efficiency of composite metal.

Detailed description of the invention

Below in conjunction with each embodiment shown in the drawings, the utility model is described in detail.It should be noted that these embodiments are not limitation of the utility model, those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection domain of the present utility model.

See a kind of detailed description of the invention of a kind of composite metal of the utility model shown in Fig. 1 and Fig. 2 100.A kind of composite metal 100, comprises titanium layer 10, first aluminium lamination 20, layers of copper 30, second aluminium lamination 40 and stainless steel layer 50, and the opposition side (i.e. the bottom of stainless steel layer 50) facing toward the side of titanium layer 10 at stainless steel layer 50 offers blind hole 501.This blind hole 501 has multiple, and these blind holes 501 are distributed in bottom stainless steel layer 50 ringwise.Blind hole 501 is conical blind hole, and the tapering of blind hole is 5-12 degree.Further, the internal face along this blind hole 501 has some circle convex ridges 511.By these blind holes 501 and convex ridge 511, the contact area of flame and composite metal 100 can be increased, improve heat conducting efficiency.Meanwhile, titanium layer 10 directly contacts with food materials, and the harmful metal elements avoided in stainless steel layer 50 is separated out and pollutes food materials under high temperature, hypersaline environment.Because the thermal conductivity of aluminum metal and copper metal is much higher than stainless steel and titanium, the heat that therefore stainless steel layer 50 can be absorbed rapidly and Transmit evenly to titanium layer 10.Therefore, the first aluminium lamination 20, layers of copper 30 and the second aluminium lamination 40 are set in titanium layer 10 with stainless steel layer 50, can further improve the heat conduction efficiency of this composite metal 100, prevent the problem that cooker sticky pot occurs or is charred.It should be noted that, also can will be arranged to the laminated construction of five layers " copper-aluminium composite beds " in this composite metal 100 between titanium layer 10 and stainless steel layer 50, to form the laminated construction of " Solder for Al-Cu Joint Welding-Solder for Al-Cu Joint Welding-aluminium " or " copper-Solder for Al-Cu Joint Welding-Solder for Al-Cu Joint Welding ".

Concrete, in the present embodiment, the titanium trade mark selected by titanium layer 10 is TA1, TA2, the stainless steel trade mark selected by stainless steel layer 50 is SUS201, SUS202, SUS301, SUS304, SUS316, SUS409, SUS410, SUS430, first aluminium lamination 20 and the aluminum metal trade mark selected by the second aluminium lamination 40 are 1050,3003, and the bronze medal number selected by layers of copper 30 is T2, T1.

The thickness of titanium layer 10, first aluminium lamination 20, layers of copper 30, second aluminium lamination 40 is equal, and is all less than the thickness of stainless steel layer 50.Concrete, the thickness of titanium layer 10, first aluminium lamination 20, layers of copper 30, second aluminium lamination 40 is 0.5mm, and the thickness of stainless steel layer 50 is 3mm.

A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.
