Problems solved by technology

At present, most metals need to be melted in the melting furnace when smelting. However, due to the oxidation of the metal itself, the molten metal is easily oxidized by oxygen, resulting in the impurity of the collected metal.
[0003] For example, in teaching or experiments, castings are often sampled to analyze their composition. When the molten metal is taken out, even if a protective gas is used, the molten liquid will inevitably come into contact with the air, causing the molten metal to be easily absorbed by the air. Oxidation will affect the quality of the metal. In addition, there may be some oxidation of the molten metal in the melting furnace

Abstract

The invention provides a sampling anti-oxidation device for molten metal, which includes a melting furnace, an opening is arranged at the top of the melting furnace, a lower closing mechanism is arranged at the opening position, an upper closing mechanism is arranged directly above the lower closing mechanism, and the lower closing mechanism and the upper closing mechanism are all arranged on the support, the top of the upper closing mechanism is provided with a lifting mechanism, and the lifting mechanism is connected with a feeding barrel, which can move up and down to enter and exit the opening. The anti-oxidation device for sampling molten metal provided by the patent of the present invention prevents the molten metal from being oxidized when taking out the molten metal. Through the combined effect of the upper and lower sealing mechanisms and the protective gas, the molten metal is guaranteed not to be oxidized to the greatest extent. The stability of the tissue composition is improved, and the validity of the test effect is improved.

Description

technical field [0001] The patent of the invention belongs to the technical field of metallurgy, and specifically relates to a sampling and anti-oxidation device for molten metal. Background technique [0002] Metal casting is a process in which metal is smelted into a liquid that meets certain requirements and poured into a mold, cooled and solidified, and cleaned to obtain a casting with a predetermined shape, size and performance. At present, most metals need to be melted in the melting furnace when smelting. However, due to the oxidizing properties of the metal itself, the molten metal in the molten state is easily oxidized by oxygen, resulting in impure metals collected during smelting. [0003] For example, in teaching or experiments, castings are often sampled to analyze their composition. When the molten metal is taken out, even if a protective gas is used, the molten liquid will inevitably come into contact with the air, causing the molten metal to be easily absorbe...
