Abstract

The invention discloses a double-layer cast iron pan casting process and relates to cookers in the field of daily life. Two iron alloys with different compositions are selected, melted and cast to form a double-layer composite cast ion pan. The cast ion pan is cast in twice, materials adopted for casting in twice are different, the inner layer contains more trace elements and enhancing components, and therefore the strength and rust resistance of the inner layer are substantially enhanced while the inner layer which is in contact with food provides necessary iron and zinc elements. Meanwhile, after casting of the inner layer and outer layer is finished, atoms of same components and different components between the inner layer and the outer layer can mutually migrate and merge by means of heat preservation for a certain time, and finally the strength and uniformity of the pan are improved.

Description

technical field [0001] The invention relates to cooking utensils in the field of daily life, in particular to a casting process of a double-layer cast iron wok. Background technique [0002] Iron is an essential element in the construction of cells. 72% of the iron in the human body exists in hemoglobin. Iron deficiency can cause anemia. There are limited sources of iron intake in daily life, and the iron element that the human body can absorb can only be active iron element. According to the Netease Health Channel report, according to statistics: about 30% of children in the country suffer from anemia, iron deficiency is still serious in women, and middle-aged and elderly people also suffer from anemia in varying degrees. [0003] Iron deficiency can reduce the activity of many iron-containing enzymes and iron-dependent enzymes in the body, affect a variety of metabolic processes, thereby impairing the functions of the nervous, digestive, muscle and immune systems, causing...
