Abstract

The invention discloses a preparation process of an alkaline earth heat-resistant magnesium alloy ingot, which belongs to the technical field of magnesium alloy production technology, and comprises the following steps: firstly preparing a talcum powder coating, a zinc oxide coating, a covering agent and a refining agent, and then adding the covering agent in the process of smelting a magnesium ingot and an aluminum ingot to control the smelting stability; next, introducing Mn element by using Al-10% Mn intermediate alloy, then adding zinc ingots, next, wrapping Mg-30% Ca by using aluminum foil, then adding the wrapped Mg-30% Ca into alloy liquid, and then adding a refining agent so as to control the refining process; and after refining is completed, pouring is conducted in a mold preheated to 200 DEG C, and a magnesium alloy ingot can be obtained after pouring is completed. The technical problems that in the prior art, a magnesium alloy preparation technology is high in cost and difficult are solved.

Description

technical field [0001] The invention relates to the technical field of magnesium alloy production technology, in particular to a preparation process of an alkaline earth heat-resistant magnesium alloy ingot. Background technique [0002] Magnesium alloys have the advantages of low density, high specific strength and specific stiffness, high electrical and thermal conductivity, excellent damping and shock absorption properties and electromagnetic shielding properties, good casting and machining properties, and easy recycling. Therefore, it has broad application prospects in aerospace, automobile manufacturing, home appliance instruments, electronic communications and other fields, and has become a very important modern industrial material. Mg-Al based alloys are the most widely used magnesium alloys due to their good die casting, machining, mechanical properties, low density, high specific strength and specific stiffness. In recent years, the requirements of energy saving, e...
