Description

Technical Field

[0001] The invention relates to the technical field of smelting, in particular to titanium alloy ingot smelting equipment with a crushing feeding structure. Background Art

[0002] However, the existing titanium alloy smelting equipment still has certain defects when in use;

[0003] For example, a titanium alloy smelting equipment that is easy to load is proposed in the application number CN202311545839.9, wherein a curved plate is symmetrically arranged on the top of the bottom ring, the inner wall of the curved plate is fixedly connected to the top of the bottom ring, the bottom end of the curved plate is fitted with the outer surface of the pressure plate, and a curved block is symmetrically arranged on the bottom of the top ring, the top of the curved block is fixedly connected to the bottom of the top ring, and a pressure ring is fixedly connected to the bottom of the curved block, and the bottom end of the pressure ring is fitted with the outer surface of the curved plate. The inclined slope of the heat insulation board is used to guide the discharged condensed water droplets to prevent them from flowing back into the smelting bin. At the same time, after the water vapor in the smelting bin is discharged, the internal pressure is reduced to ensure the safety of subsequent material addition, prevent the water vapor from not being discharged during the addition process, and cause scalding to personnel at the moment of opening, thereby reducing the danger of adding materials. In actual use, there are still the following problems:

[0004] 1. The titanium alloy smelting equipment will remove impurities in the raw materials through the feeding mechanism during the feeding process of the smelting raw materials, and the raw materials after impurities are removed are directly put into smelting. However, due to the different volumes of raw materials, the required smelting time will be different, and the smelting efficiency will be reduced when smelting raw materials of different volumes;

[0005] 2. During the smelting process of the raw materials for titanium alloy ingots, the raw materials accumulate in the internal crucible. When the internal crucible is heated by the external heating ring, the accumulated raw materials will melt from the outside to the inside, which will reduce the uniformity of smelting. In addition, the molten liquid is easy to adhere to the inner wall of the crucible during discharge, resulting in a decrease in the discharge effect.

[0006] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0007] In view of the above problems, an innovative design was carried out based on the original titanium alloy ingot melting equipment with a crushing feeding structure. Summary of the invention
