Technical Field
The invention belongs to the technical field of casting molding of special metals, and particularly relates to a crucible assembly combining bottom pouring and directional condensation.
Background
The special metal to which the patent is directed has active chemical properties and needs to be cast and molded under vacuum conditions. Meanwhile, the production line has higher requirements on the density of the final product, so that a directional solidification technology is needed to ensure that molten metal is gradually solidified from bottom to top, thereby achieving the purposes of reducing casting defects and improving the density of a metal ingot.
Disclosure of Invention
The invention aims to provide a crucible assembly combining bottom pouring and directional condensation, which can be used for casting molten metal in a bottom pouring mode and directionally condensing the molten metal. Finally, special metal ingots with the sizes and the densities meeting the requirements are obtained.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
a crucible assembly combining bottom pouring and directional condensation consists of a crucible, a plug, a die, an outer supporting cylinder, an inner supporting cylinder and water-cooled copper; the crucible is placed on an outer supporting cylinder, the plug is placed on the die, the die is placed on an inner supporting cylinder, the inner supporting cylinder is placed on the transmission mechanism, in the smelting process, the plug, the die and the inner supporting cylinder move up and down along with the transmission mechanism, and the water-cooled copper is located below the inner supporting cylinder.
When smelting, firstly placing raw materials in a crucible, adjusting the height of an inner supporting cylinder to enable a plug to plug a pouring hole at the bottom of the crucible, then vacuumizing and heating, after the raw materials are melted, lowering the inner supporting cylinder to enable the plug to be separated from the crucible, enabling molten metal to flow into a die through the plug, continuing lowering the inner supporting cylinder to enable the die to be in contact with water-cooled copper, directionally condensing the molten metal in the die from bottom to top, and taking out a finished metal ingot from the die after the smelting process is finished.
The beneficial effects obtained by the invention are as follows:
by using the crucible assembly and the matched transmission mechanism which combine the bottom pouring and the directional solidification technology, molten metal can be poured in a bottom pouring mode, and the molten metal is directionally condensed. The size and density of the finally obtained special metal ingot meet the requirements of customers.

Detailed Description
The invention will now be described in detail with reference to the drawings and specific examples.
The crucible assembly consists of a crucible 1, a plug 2, a die 3, an outer support cylinder 4, an inner support cylinder 5 and water-cooled copper 6. Wherein the crucible 1 is placed on top of the outer support cylinder 4 and remains stationary throughout the smelting process. The plug 2 is placed on the die 3, the die 3 is placed on the inner support cylinder 5, and the inner support cylinder 5 is placed on a mechanical transmission mechanism of the equipment. In the smelting process, the plug 2, the die 3 and the inner support cylinder 5 can move up and down along with the transmission mechanism. The water cooled copper 6 remains stationary during smelting. The water-cooled copper 6 is positioned below the inner support cylinder 5.
During smelting, raw materials are firstly placed in a crucible 1, and the height of an inner supporting cylinder 5 is adjusted, so that a pouring hole at the bottom of the crucible 1 is blocked by a plug 2 (figure 1). Subsequently, the vacuum is applied and the temperature is raised, and after the raw materials are melted, the inner support cylinder 5 (fig. 2) is lowered to separate the plug 2 from the crucible 1, and the molten metal flows into the mold 3 through the plug 2. The inner support cylinder 5 is continuously lowered to enable the die 3 to be in contact with the water-cooled copper 6 (figure 3), and molten metal in the die 3 is directionally condensed from bottom to top. And ending the smelting process.
And (3) assembling: the crucible assembly is assembled in the manner shown in fig. 1, ensuring that the stopper 2 blocks the pouring hole in the bottom of the crucible 1.
And (2) charging: the raw material was put into the crucible 1.
Melting: vacuumizing and heating to above the melting point of the raw materials.
A section of descent: the inner support cylinder 5 is lowered to disengage the plug 2 from the crucible 1, and the molten metal flows into the mold 3 through the plug 2, as shown in fig. 2.
The second stage is lowered: the inner supporting cylinder 5 is continuously lowered to enable the die 3 to be in contact with the water-cooled copper 6, and molten metal in the die 3 is directionally condensed from bottom to top, as shown in fig. 3.
Discharging: and (5) stopping the furnace, cooling, and discharging. The finished ingot is removed from the mould 3.
