Abstract

The invention belongs to the field of metal smelting, and in particular relates to a titanium manganese alloy smelting device. The titanium manganese alloy smelting device comprises a smelting furnace, wherein a feeding device is arranged above the smelting furnace and is connected with a feeding hole in the top of the smelting furnace through a pipeline; a vacuum pump, a molecular drag pump and an air distribution device are connected with the smelting furnace through pipelines respectively; valves are arranged on the pipelines among the vacuum pump, the molecular drag pump, the air distribution device and the smelting furnace respectively; a vacuum meter and a heating device are arranged on one side of the smelting furnace; brackets are arranged on two sides of the bottom of the smelting furnace; a discharging hole is formed in the middle of the bottom of the smelting furnace; a pouring mold with an upward opening is arranged at a position, corresponding to the discharging hole, below the smelting furnace; a cast ingot base pad and a heat-preserving base pad are sequentially arranged at the lower part of the inner cavity of the pouring mold from bottom to top; a through hole is formed in the middle of the heat-preserving base pad; a circular arc of 80 to 100 degrees is formed between the upper end surface of the heat-preserving base pad and the horizontal plane. The titanium manganese alloy smelting device is simple in structure, the air exhaust time is shortened, the air exhaust energy consumption is reduced, and the quality of a cast ingot is effectively improved.

Description

technical field [0001] The invention belongs to the field of metal smelting, and in particular relates to a titanium-manganese alloy smelting device. Background technique [0002] Roots pumps and oil diffusion pumps are the main pumps for traditional vacuum melting furnaces, which have the disadvantages of complex structure, low pumping efficiency and high energy consumption. In addition, when casting superalloys, in order to prevent the ingot from being difficult to remove from the mold, a smelting bottom pad is usually used at the bottom of the mold to prevent the ingot from sticking to the mold and prevent difficulty in removing the mold. However, the upper end surface of the bottom pad and the bottom of the ingot are prone to sticking, which makes it difficult to release the mold. In addition, the heat of the molten steel at the bottom is rapidly dissipated, causing cracks in the ingot, and the stress concentration at the bottom of the ingot during the forging process is...
