Preferably, outer layer by thermosphere be iron outer layer by thermosphere or stainless steel outer layer by thermosphere.The outer layer of this kind of magnetic conduction by
Thermosphere substantially increases heat transfer efficiency of the outer layer by thermosphere.
Preferably, the top surface of annular boss is concordant with pot mouth, side is arcwall face, the radian and internal layer of arcwall face
Radian at the identical height of work layer inner surface is identical, bottom surface and internal layer work layer outer surface rounding off.Annular boss
The intensity for substantially increasing boiler port effectively reduces its temperature distortion probability
A kind of manufacturing process of clad steel pot comprising following steps：
A. sheet stock oiling：Oiling is carried out using two sides of the oiler to sheet stock；
B. it once imitates molded:The sheet stock after oiling is carried out using press machine to be stamped and formed out internal layer work layer, by internal layer
The bottom of work layer is stamped and formed out the bottom of a pan boss, and it is convex that the lateral wall of internal layer work layer close to boiler port is stamped and formed out annular
Platform；The sheet stock of the magnetic conduction after oiling is stamped and formed out outer layer by thermosphere again, outer layer is stamped and formed out downwards by the bottom of thermosphere and is had
The pedestal of first groove, and it is convex that outer layer by the lateral wall of thermosphere close to boiler port is stamped and formed out the outer ring with the second groove
Platform；
C. it imitates for two times molded:Outer layer is wrapped on the outside of internal layer work layer by thermosphere, so as to be accommodated in first recessed for boss
In slot, annular boss is accommodated in the second groove, then internal layer work layer and outer layer are struck out one by thermosphere using press machine
Body formula pot body.
Present invention employs above scheme to have the advantages that：The present invention pass through high tonnage presses under enable aluminum alloy to or
Stainless steel holds tightly together again with magnetic conduction layer material, by high tonnage presses act on aluminum alloy materials in the case where freezing off state or
Flowed under person's heated condition, multilayered structure made to connect finer and close, the finer and closely woven arrangement of molecular structure, increase aluminium alloy or stainless steel and
The adhesive force of magnetic conduction layer material；In addition pot body MULTILAYER COMPOSITE Steel material is integrally formed, bottom stage and pot the mouth setting of pot body
Step has carried out structural strengthening to entire pot body, so that greatly reducing in the temperature distortion for reinforcing position, solves common inserted
Multiple bottom, full bottom again be easy to fall off, easy infiltration, bottom is recessed tests the problem being easily detected by.
