Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with specific implementation, which is an explanation of the present invention rather than a limitation.

[0027] 1. Analysis of influencing factors of metal magnesium reduction

[0028] 1.1 Analysis of Factors Affecting Raw and Auxiliary Materials Components

[0029] The main raw and auxiliary materials for metal magnesium reduction are: dolomite, ferrosilicon, and fluorite powder.

[0030] 1.1.1 Dolomite

[0031] In the test process of the present invention, the chemical composition of dolomite, the main raw material of metal magnesium, is analyzed. During the first Mg9995B test from October 2016 to January 2017, the testers analyzed and controlled the impurity components in the chemical composition of dolomite, such as silicon dioxide, aluminum oxide, and manganese oxide, to find out the maximum value and The minimum value is analyzed to evaluate its influence factor on the production o...

Abstract

The invention provides a production technology of Mg 9995B and above protogenetic magnesium ingot. The production technology comprises the following steps: S1, calcining dolomite to obtain calcined dolomite; S2, mixing calcined dolomite, fluorite powder and ferrosilicon to obtain a mixture, and carrying out ball-milling and pelletizing on the mixture to obtain pellet material; S3, filling the pellet material in a reducing tank, carrying out high temperature heat reduction reaction under the vacuum condition to obtain crystallized magnesium, wherein the reducing temperature is 1235-1245 DEG C;and S4, carrying out refining and pouring on the crystallized magnesium to obtain the protogenetic magnesium ingot. With adoption of the production technology, the percentage content of Mg in the protogenetic magnesium ingot is increased, the impurity element is reduced, large-scale production of Mg 9995B and above protogenetic magnesium ingot is realized, and master batch is provided for production of magnesium alloy.

Description

technical field [0001] The invention belongs to the field of production of primary magnesium ingots, in particular to a production process of primary magnesium ingots of Mg9995B and above. Background technique [0002] China is a major producer of primary magnesium in the world, with the output of primary magnesium accounting for more than 40% of the world, while the output of primary magnesium in Shaanxi accounts for nearly 62% of China, and the output of primary magnesium in Fugu County of Shaanxi accounts for more than 50% of China. [0003] Since the 1940s, magnesium alloys have been used in automobiles, aviation, aerospace and other fields. In the late 1990s, magnesium alloy products have been widely used in civil, military, electronic products and other fields. Magnesium alloys are known as "green engineering materials in the 21st century" for their light weight, heat dissipation, shock resistance, and electromagnetic radiation protection. [0004] The higher the puri...
