Cooking pot, and methods of preparation

Abstract

A cooking pot is composed of a main body made of Al alloy, a pig iron sheet wrapping part of all of said main body, and a coated layer.

Its manufacture technology includes such steps as casting said pig iron sheet, inserting it in a mould, pouring molten Al alloy, grinding, abrading, and coating. It has health-care function.

Description

technical field [0001] The invention relates to a cooking utensil and a manufacturing method thereof, specifically a cooking pot and a manufacturing method thereof. Background technique [0002] The traditional iron pot cooks the food completely like a pressure cooker, and the iron component seeps out in a very fine form, which not only tastes better, but is also very beneficial to health. However, this kind of iron pan is heavy and difficult to form, and it is not easy to produce in large quantities, and it is not easy to deal with rust. [0003] Recently, aluminum alloy cooking utensils that are lighter in weight and easier to shape are manufactured and used in large quantities. At this time, in order to prevent food from sticking, non-stick coatings are provided on the inside and outside. This aluminum alloy cooking utensil has many advantages. It is lighter and easier to shape than cast iron cooking utensils, so it can be mass-produced, and because of the non-stick coat...
