Embodiment 1

[0025] (1) Smelting pig iron and copper; respectively smelting pig iron and copper to obtain molten iron and copper. The melting temperature of molten iron is 1400°C; the melting temperature of copper is 1100°C;

[0026] (2) Casting the blank of the inner pot body: pour the molten iron into the die; then press the mold into the molten iron, pressurize and shape it through a die-casting machine, and cast the blank of the inner pot body; the casting thickness of the blank of the inner pot body is 3mm;

[0027] (3) Coarsening: After the cast inner pot body blank is cooled, the outer surface is roughened by sandblasting;

[0028] (4) Casting the pot body blank; inject copper water into the die; then use the roughened inner pot body blank as a mold to press into the die, so that the copper water and the inner pot body blank are melted and combined; Press forming, cast into pot body blank;

[0029] (5) Heat treatment of the pot body blank: heat-treat the synthesized pot body blank,...

Abstract

The invention discloses a casting method of a cast iron pan. The method comprises pig iron and copper block smelting, inner pan body workblank casting, roughening, pan body workblank casting, pan bodyworkblank heat treatment, grinding and polishing. Copper high in thermal conductivity is casted into an outer pan body to wrap an inner pan body casted through pig iron, all the positions of the whole inner pan body are evenly heated, the local high-temperature condition is avoided, and lampblack in the use process cannot be generated; and in addition, the cast iron pan is fragile, the copper layer wrapping the outer surface of the cast iron pan achieves the good protection effect, and the anti-breaking capacity of the cast iron pan is improved.

Description

technical field [0001] The invention relates to the field of kitchen utensil production, in particular to a casting method of a pig iron pot. 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. Contents of the invention [0003] The object of the present invention is to provide a cast iron pot casting method, using pig iron as t...
