Multi-layer compound-bottom aluminum pot

Abstract

The invention provides a multi-layer compound-bottom aluminum pot, comprising a pot body, wherein the bottom part of the pot body is connected with a plurality of metal materials to form the compound pot bottom by extrusion; the plurality of metal materials are as follows: a high heat-conductive layer, a double-direction connection sheet, aluminum alloy and magnetic steel; the high heat-conductive layer is melted to cover the double-direction connection sheet; the highly heat-conductive layer has good and uniform heat conduction performance; the aluminum alloy is compounded with the magnetic steel to form a metal plate with a flat surface; the magnetic steel compound bottom can be used for all kinds of stoves; as the surface of the compound metal plate is flat, the compound metal plate can be used for avoiding scratching the surface of an induction stove when the compound metal plate is used on the induction stove; convex holes at the front side of the double-direction connection sheet face the pot bottom and concave holes at the back side of the double-direction connection sheet face the compound metal plate, so that the pot bottom and the metal plate are extruded to form the compound-bottom aluminum pot by the double-direction connection sheet via the high-strength extrusion process at normal temperature; the compound pot bottom is formed by direct extrusion at normal temperature. When the multi-layer compound-bottom aluminum pot provided by the invention is used, the phenomena of deformation and falling of the compound bottom of the aluminum pot caused by the heat expansion can be effectively avoided. The high-strength extrusion process is simple and convenient, does not cause environmental pollution and noise pollution in the production.

Description

technical field [0001] The invention relates to a multilayer composite bottom aluminum pot. Background technique [0002] At present, aluminum pots in the cooker market cannot be used in induction cookers, because aluminum pots themselves do not have the function of magnetic conduction, so they cannot be used in induction cookers. Some aluminum pots that can be used on induction cookers all adopt thermal re-strike technology, brazing technology, and perforated double-bottom technology. Add one or more layers of iron or stainless steel metal plates or perforated metal plates to the bottom of the pot. The aluminum pan can be widely used on various stoves including induction cookers. When the single-layer compound bottom is heated, it will cause local high temperature phenomenon at the bottom of the pot, making the food mush, and at the same time, oily fume will be produced, which is harmful to the human body to a certain extent. [0003] There are following defects in adopt...

AI Technical Summary

Problems solved by technology

It will cause pollution to the surrounding environment, and it will also cause shedding when dry burning and affect the overall appearance of the pot.

[0006] Porous compound bottom technology: the firmness is unreliable, the concave and convex deformation of the bottom of the pot after heating will affect the use, and the porous compound bottom is easy to scratch the surface of the induction cooker
