A protective melting furnace for infusing anti-oxidation magnesium alloy gas with argon gas in the laboratory

Abstract

The invention discloses a laboratory argon filling anti-oxidation magnesium alloy gas protective smelting furnace. The laboratory argon filling anti-oxidation magnesium alloy gas protective smelting furnace structurally comprises a funnel-opening groove seat, a grid top cover, a gas exhaust hot pouring gate, an octagonal cover plate, eight thin film plates, an eight-face smelting furnace box and an S-shaped inert gas pipe; the eight thin film plates are vertically attached to the eight front faces of the eight-face smelting furnace box correspondingly; and the S-shaped inert gas pipe is installed in the eight-face smelting furnace box. According to the laboratory argon filling anti-oxidation magnesium alloy gas protective smelting furnace, the effects that the funnel-opening groove seat cooperates with the S-shaped inert gas pipe, an inert gas tank is opened, argon is poured into an S-shaped interlayer pipe through a gas conveying pipe so that magnesium alloy gas can be protected, then, the magnesium alloy gas is guided to meet and flow into a gas collecting barrel beam tube through a three-branch bottom pipe of a four-way funnel groove, when the argon arrives at the whole smeltingfurnace to protect the magnesium alloy gas, the gas quality is checked, the gas is guided for rising accumulation, the situation that chemical reaction is performed in advance, and magnesium alloy gas is consumed is avoided, magnesium liquid is heated by argon transition hot gas for vaporization and rising efficiently, and protection is achieved are realized.

Description

technical field [0001] The invention relates to a laboratory-used protective smelting furnace for infusing anti-oxidation magnesium alloy gas with argon gas, belonging to the field of experimental gas protection equipment. Background technique [0002] The protective smelting furnace for magnesium alloy gas used in the laboratory is an operation method in which the heated furnace body evaporates magnesium liquid, so that the extraction of magnesium alloy gas has a tightness, and the interference of external impurities can be reduced, and it also protects magnesium in a broad sense. implementation, but the metal properties of magnesium are unstable, and it is easy to produce the effect of interfering with the experimental function. The shortcomings of the current technology to be optimized are: [0003] Magnesium reacts violently when it is heated, and is an active metal. When the liquid magnesium is heated and changes its molecular structure into a gas, the calorific value i...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a protective smelting furnace for infusing an anti-oxidation magnesium alloy gas with argon gas in a laboratory, so as to solve the problem that magnesium reacts violently when it is heated and is an active metal. When the liquid state of magnesium is heated and changes When the molecular structure is formed into gas, the calorific value is accumulated on the oxide film of the magnesium liquid, and the heated magnesium liquid is gradually eroded to make it deteriorate. When the magnesium alloy gas fills the furnace and contacts the oxide film, and the heat of the oxide film reaches a critical value, it will cause an explosion. A problem that greatly affects the protection efficiency and production volume of magnesium alloy gas
