Abstract

The invention relates to a cooking pot and a preparation method thereof, belongs to the field of cooking pots, and aims to solve the problem that food is burnt and is difficult to clean due to poor heat-conducting property of an existing pot, and adopts the technical scheme as follows: the cooking pot comprises an iron matrix made of refined iron or cast iron; open fire cooking or electromagnetic cooking is facilitated; the heat conduction layer is tightly attached to the lower surface of the iron base body, and the heat conduction layer is a copper layer or a silver layer; the stainless layers are formed on the upper surface and the top surface of the iron base body; the bottom surface of the heat conduction layer is coated with the magnetic conduction layer; and the anti-corrosion layer covers the side surface of the heat conduction layer and the bottom surface of the magnetic conduction layer. The heat conduction layer made of copper or silver is good in heat conduction performance and arranged on the lower surface of the iron base body, heat can be quickly conducted to the whole iron base body, uniform heating is guaranteed, heat gathering is reduced, and the problem that food is burnt and stuck to the pan due to local heat gathering of the pan body can be effectively solved. The invention also discloses a preparation method of the cookware.

Description

technical field [0001] The invention belongs to the field of cooking pots, and particularly relates to a cooking pot and a preparation method thereof. Background technique [0002] The existing iron cookware has the problem of slow heat conduction, especially when heating by electromagnetic coils, the bottom of the cookware is close to the electromagnetic source, and the side wall of the cookware is far away from the electromagnetic source. It is easy to be heated unevenly, and it is easy to burn the pot in severe cases, which is difficult to clean; if you use hard tools to clean the pot, it is easy to damage the pot, and if you use water to soak the pot, the pot is easy to rust. utensils to reduce the problem of difficulty in cleaning caused by the local heating of the food. SUMMARY OF THE INVENTION [0003] Aiming at the problem that the poor thermal conductivity of the existing cookware causes the food to stick to the pan and is difficult to clean, the present inventio...
