Embodiment
[0030] The specific and detailed preparation process of the magnetically conductive cookware according to the embodiment of the present invention is as follows:
[0031] Stamping magnetic energy sheet: cold stamping die, making a circular magnetic energy sheet, and doing phase fusion trimming on the surface of the magnetic energy sheet; the outer diameter of the magnetic energy sheet (Thickness), using a blanking die, using a 100T ton force punch to blank; then using a punching die to punch dark holes on the magnetic energy sheet, the inner diameters include: 1, X8, 12. The magnetic energy sheet uses a plane sander, and uses a 240# abrasive belt to process the surface with a sand pattern of about 0.05mm.
[0032] Casting mold: place the prepared magnetic energy sheet in the mold cavity and fix it; cast it into the smelted liquid aluminum alloy liquid, the smelting temperature is 700-800°C, and pour it with a quantitative heat preservation container of about 2.5kg Put i...

Abstract
The invention discloses magnetic cookware and a manufacturing process thereof. The manufacturing technique comprises the following steps: (1) manufacturing a circular magnetic energy sheet with a plurality of hidden hole structures and performing melting finishing on the surface of the magnetic energy sheet through a cold stamping mold; (2) placing the manufactured magnetic energy sheet in a casting mold cavity to be fixed, casting liquid-state alloy and manufacturing a cookware blank of which two phases are melted integrally through natural cooling; (3) finishing the bottom of the manufactured cookware blank through a punching die, then finishing the flatness of the cookware bottom and eliminating the internal stress of the magnetic energy sheet on the middle part of the cookware bottom; and (4) performing machine tool surface cutting on the blank which is subjected to the treatment of the steps. According to the magnetic cookware and the manufacturing technique thereof, the magnetic energy sheet is cast into the alloy cookware, so that the cookware is more stable and longer to use, the efficacy is improved, and the energy is saved.
Description
technical field [0001] The invention relates to an alloy pot, in particular to a magnetically conductive pot in which a magnetic energy sheet is cast into the alloy pot and a manufacturing process thereof. Background technique [0002] At present, the induction cooker is a commonly used magnetic cooker in the family, and only the cooker with a magnetically conductive bottom can achieve the effect of magnetic conduction heating and cooking domestic food. Induction cookers usually also require an all-stainless steel or multi-layer composite metal bottom aluminum pot and a magnetic conductive sheet to be embedded in the bottom of the pot. [0003] Existing aluminum alloy cookware adopts the method of pressing in the magnetic conductive sheet to achieve the effect of magnetic conduction and heat transfer. With the method of pressing in, the stability performance is low, and the situation of falling off occurs. Contents of the invention [0004] The purpose of the present inve...
