A kind of soot-free pig iron pan and its manufacturing method

Abstract

The invention discloses a smokeless cast iron wok and a manufacturing method thereof, and belongs to the field of kitchenware. The smokeless cast iron wok comprises a wok body, wherein the work body comprises an outer wok body, an inner wok body and a stainless steel coating; the outer wok body is cast from copper; the bottom of the outer surface of the outer wok body adopts a plane structure; the inner surface of the outer wok body and the outer surface of the inner wok body are combined in a fusion manner; the inner wok body is cast from cast iron; the bottoms of both the outer surface and the inner surface of the inner wok body adopt a circular-arc structure; the stainless steel coating is sprayed onto the inner surface of the inner wok body; and the stainless steel coating contains silicon, manganese, chromium, nickel, molybdenum, nitrogen, copper, cobalt, boron, carbon, niobium, calcium, phosphorus, sulfur and the balance of iron. The invention further provides the manufacturing method of the smokeless cast iron wok. The smokeless cast iron wok disclosed by the invention can be heated uniformly, can be prevented from generating smoke, is large in heated area and low in breakage possibility, and can be protected from rust erosion.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to a smoke-free pig iron pan and a manufacturing method thereof. Background technique [0002] The wok that is generally used now generally adopts a single-layer thin iron sheet through stamping or pig iron casting. Due to the poor thermal conductivity of the wok made of these two materials. When cooking, the pot body is heated unevenly, and high temperature is generated locally, especially the highest temperature at the waist of the pot, followed by the bottom of the pot, and the lowest temperature at the edge of the pot. After a series of complex changes of edible oil and food under high temperature conditions, a large number of thermo-oxidative decomposition products are produced, some of which are released into the air in the form of smoke to form oil fume. The components that make up the lampblack are complex, and most of them are toxic, such as heterocyclic amines, which are ...

AI Technical Summary

Problems solved by technology

The components that make up oil fume are complex, and most of them are toxic, such as heterocyclic amines, which are strong carcinogens

Oil fume has a great impact on human health, and it will pollute the environment when it is discharged into the atmosphere
