Example Embodiment

[0027] Example 1:

[0028] No. 22 cast iron is used as the raw material, and it is smelted by ordinary technology at a temperature of 800-900 ℃. After smelting, it is processed into a pot semi-finished product according to the shape of the pot according to the existing method of casting and processing pot, and then passes through ordinary sanding The equipment removes the oxide scale sand on the surface of the semi-finished cast iron pot and removes the dust on the surface. The mouth of the semi-finished cast iron pot is ground into rounded corners with ordinary grinding equipment, and the side of the semi-finished cast iron pot is drilled with holes for installing handles.

[0029] Put the cast iron pot semi-finished product after the above drilling into a vacuum nitriding furnace with good sealing performance. The space of the vacuum nitriding furnace is 2 cubic meters. It can hold 200 semi-finished cast iron pots of 32 cm in one time, using a vacuum pump Take out the air with a...

Abstract

The invention provides a fabricating method of a stainless cast iron cooker, which belongs to the technical field of the fabrication of daily goods and solves the problems of higher cost, lower rigidity, poorer wearing property and corrosion resistance, shorter service life, and the like. The fabricating method of the stainless cast iron cooker comprises the following steps: A. forming; B. nitrogen stainless treatment; and C. oil finish. The invention has the advantages of good rust prevention property, high safety performance, good iron supplementation effect, favorable rigidity and wearing property, long service life, and the like.

Description

technical field [0001] The invention relates to a method for making cookware; in particular, to a method for making cast iron cookware with high antirust ability; the method is also suitable for iron cookware that is pulled up or formed by ordinary cold-rolled iron plates; belongs to The production technology field of daily necessities. Background technique [0002] Cooking utensils are closely related to people's lives, and cooking utensils are closely related to people's lives. Existing cooking utensils are mainly made of materials such as cast iron, stainless steel, copper, and enamel. Cookware made of stainless steel is elegant in appearance, light and durable, corrosion-resistant and rust-free. However, stainless steel cookware is made of iron-chromium alloy infiltrated with nickel, molybdenum, titanium, cadmium, manganese and other trace elements. These trace metals are harmful to the human body; , beneficial to the human body; but after rusting, "patina" and blue vi...
