Embodiment 1

[0017] A production method of an ecological pot is carried out according to the following steps: firstly, heating the ductile iron to 1500 degrees and melting it into molten iron, then pouring the molten iron into the mold of the ecological pot, and forming a pot blank after cooling; placing the cooled pot blank in a Put it into the electric furnace for heating, stop heating when the heating temperature reaches 980 degrees, and keep the constant temperature for 10 minutes. Elements such as manganese, phosphorus, sulfur, and magnesium are precipitated from the billet beyond the melting point. Expose the pot blank to the air for natural air cooling; after cooling to room temperature, the precipitated elements solidify on the pot blank surface to form slag attached to the pot blank, and then polish the inner surface of the pot blank to remove the inner surface of the pot blank slag until smooth. After polishing, the inner surface roughness of the ecological pot reaches 0.4μm-0.8μ...

Embodiment 2

[0020] A production method of an ecological pot is carried out according to the following steps: firstly, heating the ductile iron to 1575 degrees and melting it into molten iron, then pouring the molten iron into the mold of the ecological pot, and forming a pot blank after cooling; placing the cooled pot blank in a Put it into the electric furnace for heating, stop heating when the heating temperature reaches 1015 degrees, and keep the constant temperature for 8 minutes. Elements such as manganese, phosphorus, sulfur, and magnesium are precipitated from the billet beyond the melting point. Expose the pot blank to the air for natural air cooling; after cooling to room temperature, the precipitated elements solidify on the pot blank surface to form slag attached to the pot blank, and then polish the inner surface of the pot blank to remove the inner surface of the pot blank slag until smooth.

Embodiment 3

[0022] A production method of an ecological pot is carried out according to the following steps: firstly, heating the ductile iron to 1650 degrees and melting it into molten iron, then pouring the molten iron into the mold of the ecological pot, and forming a pot blank after cooling; placing the cooled pot blank in a Put it into the electric furnace for heating. When the heating temperature reaches 1050 degrees, stop heating and keep the constant temperature for 5 minutes. Elements such as manganese, phosphorus, sulfur, and magnesium are precipitated from the billet beyond the melting point. Then turn off the power of the electric furnace and take out the billet from the electric furnace. Expose the pot blank to the air for natural air cooling; after cooling to room temperature, the precipitated elements solidify on the pot blank surface to form slag attached to the pot blank, and then polish the inner surface of the pot blank to remove the inner surface of the pot blank slag u...

Abstract

The invention provides a method for making an ecological boiler. The method comprises the following steps: heating ductile cast iron to 1,500-1,650 DEG C, melting into molten iron, pouring the molten iron into a die of the ecological boiler, and cooling to form a boiler blank; placing the cooled boiler blank into an electric furnace for heating, stopping heating when the heating temperature reaches 980-1,050 DEG C, preserving heat for 5-10 minutes, taking the boiler blank out of the electric furnace, and naturally cooling in the air to the room temperature; polishing the inner side surface of the boiler blank, and removing slag on the inner side surface of the boiler blank till the surface become smooth. Since the ecological boiler is made of the ductile cast iron which is high in toughness, the ecological boiler is prevented from being broken and deformed; the ductile cast iron can be used for conducting heat rapidly and is heated uniformly, and heat can be transferred rapidly during use of the made ecological boiler, thereby preventing the temperature of the inner side surface of the boiler body from getting too high, preventing the oil temperature from reaching a smoke point and realizing a smoke-free effect. The made ecological boiler is free from a chemical coating and ceramics falling, and has a rust prevention function.

Description

technical field [0001] The invention relates to the technical field of iron pot manufacturing, in particular to a method for manufacturing an ecological pot. Background technique [0002] In the history of the use of iron pots, cast iron pots have always been popular cooking utensils among the people, especially in rural areas. The cast iron pot conducts heat evenly, and the pot body will never be deformed, which can effectively relieve iron deficiency anemia, which is unmatched by other cookware products. But traditional cast iron pots are extremely prone to rust and are not easy to clean. With the improvement of living standards, in the early 1990s, the newly developed enamel technology temporarily solved the problem of easy rust. However, due to the incompatibility of enamel and pig iron, the enamel pots are often de-enamelled in daily use, and this problem has not been effectively solved so far. . In the future, the non-stick pan technology represented by Supor has al...
