Problems solved by technology

Chinese patent application No. 88102637.9 discloses a method of adding selenium to molten steel, which is to add selenium powder and other metal powders into the molten steel after being compressed into blocks, but selenium is easy to gasify at high temperature, and the recovery rate of selenium is not high. Ideal, waste of selenium-containing raw materials, so it is necessary to find new ways to add selenium

Abstract

The invention discloses a selenium-rich iron pot, which is characterized by being prepared mixing pig iron, selenium-copper alloy and selenium-zinc alloy according to a certain weight ratio, smelting,and carrying out die casting for molding; the selenium-rich iron pot is prepared from the following components by a ratio (weight percent): 0.101-1.01% of Se, 0.005-0.05% of La, 0.005-0.05% of Ce, 1.20-1.40% of Si, 0.5-0.7% of Mn, 0.1-1.0% of Zn, 0.48-1.88% of Cu, 0.0175-0.116% of Ag, 0.002-0.024% of P and the balance of Fe. The invention also provides a manufacturing method of the selenium-richiron pot. The trace element release amount of the selenium-rich iron pot provided by the invention is 20-30% of the daily intake standard of a human body during normal cooking, and the selenium-rich iron pot can release a rare earth La/Ce element, so as to meet the demand for trace elements of the human body.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, more specifically, it relates to a selenium-enriched iron pot and a manufacturing method thereof. Background technique [0002] At present, most of the cooking utensils used for cooking, cooking and boiling water are made of stainless steel and aluminum. Stainless steel cookware cannot release trace elements that are beneficial to health during the cooking process. Long-term use of aluminum cookware will cause the brain to decline and age, which is not conducive to human health. The cooking pot made of pig iron in our country contains iron, silicon, manganese and other elements. This kind of pot releases iron element during the cooking process, which is beneficial to the human body's blood enrichment, but it is beneficial to the human body's trace elements, especially selenium element. . Therefore how to prepare selenium-enriched iron pot (so that the pot can release the selenium elem...
