Detailed Description
For a clearer description of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings.
Example one
See fig. 1, 2, 3, 5 and 6.
An ingot casting container comprises a die 12 made of metal or alloy material, a first plug body 16 and a second plug body 29.
The die 12 comprises a cavity 13 which is made of metal or alloy and has an upward opening, and an accommodating groove 14 which is arranged at the center of the bottom of the die 12, wherein the accommodating groove 14 is a circular truncated cone-shaped through groove with the inner diameter gradually increasing from top to bottom and penetrates through the bottom of the die 12; the outside of two opposite side surfaces of the die 12 is symmetrically provided with 1 each of the lugs 15 for hooking the ingot casting container and the rare earth metal in the ingot casting container. The number of the hanging lugs 15 can be more, and the hanging lugs are suitable for hanging the ingot casting container and rare earth metals in the ingot casting container.
The first plug body 16 includes a first clamping plate 19 and a recess 17. The upper half of the first plug 16 is shaped to fit into the receiving groove 14. a downward groove 17 is provided in the top surface of the first plug 16, and a first clamping plate 19 is located at the bottom.
The second plug body 29 is provided with a platform 21, a plug head 22 and a second clamping plate 23, and the second clamping plate 23, the platform 21 and the plug head 22 are connected into a whole in sequence from top to bottom. The plug 22 is matched with the groove 17 in shape, but is slightly smaller than the groove 17, and a gap is formed between the plug 22 and the groove 17 after the plug is plugged into the groove 17. The platform 21 is a thin plate having a larger circumference than the recess 17 in the top surface of the first plug 16. The second clamping plate 23 is a cube, and a second hole 24 is horizontally formed in the middle of the second clamping plate.
During the ingot casting container, the upper half of first cock body 16 is arranged in holding tank 14 according to top surface (the one side that is provided with recess 17) from bottom to top, pluggable, and the top of first cock body 16 is not higher than the end of die cavity 13. The bottom of the recess 17 is lower than the lowest point of the mould cavity 13. The plug 22 of the second plug 29 is placed in the recess 17 of the first plug 16 or, in use, the plug 22 is placed in the recess 17 of the first plug 16.
When the plug is used, the second plug body 29 is taken out, a proper amount of molten electrolyte (or called fused salt) is injected into the cavity 13 and the groove 17, the second plug body 29 is immediately plugged into the groove 17, redundant electrolyte is extruded out, after the electrolyte remained in a gap between the groove 17 and the plug head 22 is solidified, the second plug body 29 is taken out by clamping the second clamping plate 23 or hooking the second hole 24, and the solidified electrolyte is adhered to the inner surface of the groove 17. Then, when the liquid rare earth metal is injected into the mold 12, the temperature of the mold 12 is raised by heating, and the liquid rare earth metal is cooled and solidified. Then the liquid rare earth metal enters the groove 17, the first plug 16 is heated to a higher temperature, a small amount of electrolyte originally solidified on the inner wall and the bottom of the groove 17 absorbs the heat of the liquid rare earth metal to be remelted, and at least one part of the electrolyte is blocked in the groove 17 by the liquid rare earth metal; the detection column 26 is kept in a liquid state before solidification and in the initial solidification stage, heat released in the solidification and cooling processes of the detection column 26 is continuously transmitted to the first plug body 16, the first plug body 16 absorbs the heat by itself and further transmits the heat to other substances, the detection column 26 is usually solidified within 1-2 minutes, then the first plug body 16 can be removed under the protection of protective gas or under vacuum, and if necessary, the detection operation can be finished after waiting for 2-3 minutes (namely 3-5 minutes after the liquid rare earth metal is injected into the mold 12) and detection data such as weight, impurity content and the like can be obtained. At this time, the rest of the rare earth ingot 25 is not completely solidified, and the surface temperature is also higher than the spontaneous combustion temperature. But the cooling rate of the detection column 26 is much greater than that of the remaining portion of the rare earth ingot 25. In the groove 17, as the temperature of the detection column 26 is further reduced, the volume thereof is continuously reduced, and a gap is naturally generated between the detection column 26 and the groove 17. Since the solidification temperature of the electrolyte is lower than that of the rare earth metal, a small amount of the electrolyte in the recess 17 is filled in a naturally occurring gap between the detection column 26 and the recess 17, and heat from the detection column 26 is continuously transferred to the first plug 16. The small amount of electrolyte in recess 17 eventually solidifies centrally at the bottom of recess 17 and surrounds the outside of detection post 26, and after removal of first plug 16, is kept free of air, continuing to protect detection post 26 until stripped. When the first plug 16 is installed, the first clamp plate 19 can be clamped by using a proper tool for installation; the first plug 16 can also be removed by clamping the first clamping plate 19 with a suitable tool.
The electrolyte film layer solidified on the inner wall and bottom of the recess 17 also prevents the defect that the detection column 26 is solidified too fast by direct contact with the first plug 16 while it is still in a liquid state.
The circular truncated cone-shaped receiving groove 14 can be changed into a multi-edge truncated cone shape, and the shape of the upper half part of the first plug 16 can be still adapted to the receiving groove 14.
Although when the second plug 29 is not used, the recess 17 will be filled with electrolyte; when the liquid rare earth metal is injected into the cavity 13 and the groove 17, because the temperature of the liquid rare earth metal is higher than the melting point of the electrolyte, the electrolyte in the groove 17 is heated and melted, and is extruded out of the groove 17 by the liquid rare earth metal with higher density, and the detection column 26 is formed in the groove 17 after the liquid rare earth metal is cooled.
The use of the second plug 29 ensures that the sensing pin 26 cools and solidifies outside the mold 12; the cooling rate of the detection column 26 is increased.
Example two
See fig. 1, 2, 4, 5 and 6.
The ingot container of this embodiment is substantially the same as that of the first embodiment except that a horizontal through hole 20 is formed in the center of the first clamping plate 19.
When the first jaw 19 is removed, the first plug 16 may be removed by gripping the first jaw 19 with a suitable tool. The first plug body 16 can also be removed by pulling the horizontal through hole 20 of the first jaw 19 with a suitable hook.
EXAMPLE III
See fig. 1, 2, 4, 5 and 6.
The ingot container of this embodiment is substantially the same as the first embodiment, except that it is centered on the first plug body 16. Firstly, the top of the first plug body 16 is 2-3 mm higher than the bottom of the cavity 13; secondly, the lower half part of the first plug 16 is a cylinder, and thirdly, the first clamping plate 19 at the bottom in the first embodiment is replaced by a limiting member 18 fixed on the side surface of the cylinder.
The top surface of the first plug 16 is slightly higher than the bottom of the cavity 13 in the mold 12, so that the defect that the liquid rare earth metal initially injected into the cavity 13 directly enters the groove 17 at a lower temperature due to heat transfer to the mold 12 and is solidified before reaching the bottom of the groove 17 can be avoided, and the routine of 'pinching and removing the head and the tail' of material sampling is also met.
The receiving groove 14 may also be cylindrical, and the upper half of the first plug 16 is also cylindrical accordingly. But the accommodating groove 14 should not be a truncated cone shape having an inner diameter gradually decreasing from top to bottom.
Example four
An ingot casting container, see fig. 1, fig. 2, fig. 4, fig. 5 and fig. 6.
This embodiment is substantially the same as the third embodiment, except that it further includes an auxiliary basin 27 and a metallic tin 28. The auxiliary basin 27 is a container with an upward opening, and a proper amount of metal tin 28 is arranged in the auxiliary basin. The tin 28 has a depression formed therein that is shaped to conform to the cylindrical portion of the first plug 16. The lower end of the cylindrical body of the first plug 16 is placed in a depression in the middle of the tin metal 28.
In use, the first plug 16 itself absorbs heat from the detection column 26 and transfers heat from the detection column 26 to the metallic tin 28, thereby accelerating the cooling of the detection column 26. The ingot container and rare earth metals may be transported in an auxiliary basin 27.
If necessary, objects (not shown) for supporting and stabilizing the mold 12 can be arranged in the metallic tin 28.
The metallic tin may be replaced by lead, lead-tin alloy, heat conductive oil, or the like.
EXAMPLE five
An ingot casting container, see fig. 1, fig. 2, fig. 4, fig. 5 and fig. 6.
The present embodiment is substantially the same as the fourth embodiment, except that the metallic tin is located between the outer bottom surface of the mold 12 and the highest point of the limiting member 18 of the first plug 16, so as to wrap the limiting member 18. Because of the low melting point of the metallic tin, the metallic tin around the first plug 16 is melted after receiving the heat transferred by the first plug 16, and the first plug 16 is integrated with the metallic tin 28 and the auxiliary basin 27 after the metallic tin 28 is solidified.
When the first plug 16 is separated from the detecting column 26 after the metallic tin 28 is solidified, the lifting lug 15 can be directly hooked to lift the mold and the rare earth metal 25, and the first plug 16 is separated from the detecting column 26 by using the weight of the first plug 16, the metallic tin 28 and the auxiliary basin 27. The metal tin can be replaced by lead, tin-lead alloy, paraffin, heat conducting oil, etc.
Finally, it is noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
