Alterant for producing high-strength cast-iron nutrient frying-disc by furnace cupola and method for manufacturing same

Abstract

The invention discloses alterative which is used on a furnace cupola to produce high-strength cast iron pan with nutrient elements and a production process thereof, which is mainly used to conduct modification treatment for liquid cast-iron when applied on casting high-strength cast iron pan with nutrient elements. The alterative of the invention comprises elements which have greater nutrient roles for human bodies such as Ca, Zn, Mg, Cu, Sr, B and Si, wherein the weight percentage content of each chemical component is that 2-5% Ca, 2-5% Zn, 1-4% Mg, 2-10% Cu, 0.1-0.8% Sr, 0.1-0.5% B, 37-50% Si and the rest is Fe. Pots and pans such as iron pans or pans and the like which are produced through utilizing the alterative of the invention not only can increases the mechanical property of pots and pans such as strength and the like, strengthens the pearlite capacity of cast iron and guarantees the sufficient ink ability, but also makes the pots and pans have nutrient health function, and the alterative has larger brittleness, which can be disintegrated into grain size which is needed in production, thereby conveniently using.

Description

technical field [0001] The invention relates to a modifier for cast iron, in particular to a nutritional modifier for producing high-strength cast iron nutritional frying pans in a cupola and a manufacturing method thereof. Background technique [0002] The research results of human nutrition have shown that the occurrence of many diseases is closely related to the lack of trace elements in the human body. The trace elements necessary for the human body are basically obtained through diet, and the elements in the cooking utensils for making food will penetrate into the food little by little. With people's understanding of this point of view, aluminum cookware, which is considered harmful to the human body by experts, has gradually been neglected, while iron cookware has been favored because it is beneficial and harmless to the human body. The United Nations, Education, Culture and Health Organization also advocates the use of iron cookware to improve people's health. Nutri...

[0003] Chinese patent 94213349.8 discloses a cast iron nutrition and health care pot with a double bottom, and it is mentioned in the patent document that Zn (zinc), Ca (calcium), Mo (molybdenum), Mg (magnesium), K (potassium), Li (lithium) and more than a dozen nutritional elements, but it does not mention how to add these elements to cast iron

[0007] At present, the role of cast iron modifiers is generally to improve the mechanical properties of cast iron parts such as strength and toughness. There is no modifier that can be used with cast iron cookware to improve the nutritional content of cast iron cookware.
