Abstract

The invention discloses a high-strength enamel pan and a production technology thereof. The high-strength enamel pan comprises a cast iron pan body and an enamel glaze layer attached to the surface of the cast iron pan body, wherein the cast iron pan body comprises components including iron, manganese, vanadium, tungsten, aluminum, molybdenum, cerium and carbon, and the enamel glaze layer comprises raw materials including quartz, albite, calcined kaolin, magnets, shell powder, borax, iron oxide powder, aluminum oxide powder, silica powder and an additive. The adopted enamel glaze layer of the high-strength enamel pan adopts conventional ingredients such as the conventional quartz, potash feldspar, the calcined kaolin, the borax and the like, the magnets, the shell powder, the iron oxide powder, the aluminum oxide powder, the silica powder and the additive are also added, so that the enamel glaze layer sintered at the relatively lower temperature can have the same strength and density, and glaze layer damage caused by bumping is reduced as much as possible.

Description

technical field [0001] The invention relates to cooking utensils in the field of daily life, in particular to a high-strength enamel pot and its manufacturing process. Background technique [0002] The enamel pot is to adhere a layer of inorganic vitreous material on the base of the metal pot, and then melt and condense on the metal base and firmly bond with the metal to form a layer of enamel on the surface of the pot. At the same time, due to the stable chemical properties of the enamel pot, it can store mildly acidic and alkaline foods. [0003] Existing enamel pans are generally white, and the used glaze solvents of white enamel are silicon oxide, aluminum oxide, manganese oxide, potassium oxide and sodium oxide, and are lead-free, so there is no danger of aluminum poisoning. But because the enamel layer of this enamel pot is extremely easy to break under the situation of bumping, therefore, cause it to need very careful in use, prevent the breakage of enamel layer. C...
