Magnesium-zinc-selenium alloy material for kitchen ware and preparation method thereof

Abstract

The invention discloses a magnesium-zinc-selenium alloy material for kitchen ware. The magnesium-zinc-selenium alloy material is prepared from the following components in proportion by weight: 1%-5% of zinc, 0.3%-1% of calcium, 0.2%-0.5% of selenium and the balance of magnesium. A preparation method for the magnesium-zinc-selenium alloy material comprises the following steps: step I of putting pre-heated pure magnesium ingot and a magnesium-calcium intermediate alloy into a crucible to heat and melt, and using a solvent to cover and protect; and step II of rising the temperature to 700-720 DEGC to add zinc and tin selenide, stirring until components are uniform after melting, thereby obtaining the magnesium-zinc-selenium alloy. The preparation method has the advantages that magnesium is taken as a base material, and trace elements zinc, calcium and selenium are added to realize alloying; and the prepared magnesium-zinc-selenium alloy has better heat conduction in comparison with iron,is made into kitchen ware, so that trace element supplement of a human body can be realized, and therefore, body health is facilitated.

Description

technical field [0001] The invention relates to the technical field of kitchen utensil manufacturing, in particular to a magnesium-zinc-selenium alloy material for kitchen utensils and a preparation method thereof. Background technique [0002] At present, kitchen utensils are mainly made of iron, aluminum and stainless steel. Although iron materials are good for human health, they are easy to rust, heavy and inconvenient to use; although stainless steel materials are beautiful in appearance and not easy to rust, they have poor thermal conductivity and are easy to paste; It is also light, but long-term use will cause harm to human health. In order to avoid the impact of this hazard, the surface is generally coated with non-stick coatings, and this type of coating will decompose when the temperature reaches a certain value, and the decomposition products will be harmful to the human body. Health brings hidden dangers, and long-term use of such kitchen utensils for cooking wi...
