Abstract

The invention discloses a continuous preparation method of a gallium-based liquid alloy. Based on crucible furnace equipment with a glove box, in a preparation process, the preparation process of thegallium-based liquid alloy at least comprises the following steps of A, preparing materials; B, preheating a crucible furnace; C, refining the gallium-based liquid alloy by sealed heating; and D, refining the gallium-based liquid alloy by continuous cyclic heating. According to the preparation method, multiple steps of charging, atmosphere smelting, melt purification, cooling, product packaging, crucible cleaning and the like required in the liquid metal smelting process are integrated together to form a continuous production line, a bubbling deslagging process and a novel crucible structure design are introduced, an integrated smelting method of the continuous preparation method of the gallium-based liquid alloy is formed, the method has the advantages of being high in automation degree,small in occupied area, low in energy consumption and the like, production expansion can be achieved by increasing the number of equipment, the requirement for large-scale production is met, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of a gallium-based liquid alloy preparation device and a preparation method, in particular to a continuous preparation method of a gallium-based liquid alloy. Background technique [0002] Metal alloys that are liquid at room temperature in nature include mercury, cesium, francium and gallium, and their corresponding melting points are –38.87°C, 28.65°C, 27°C and 29.8°C, respectively. Among them, mercury is highly volatile and highly toxic; cesium is easily oxidized in the air and reacts violently with water; francium is an unstable radioactive element; only metal gallium is harmless to the human body and is a safe metal . Metal gallium, indium, tin, etc. are prepared into eutectic alloys, and metals that are liquid at room temperature can be obtained. Among them, gallium indium tin alloy (melting point -19°C) and gallium indium alloy (melting point: 15.6°C) are both liquid at room temperature. [0003] Ga...
