Abstract
The utility model relates to a down-flow type crucible for smelting high-purity magnesium and magnesium alloy. The utility model includes a crucible positioned in a resistance furnace and a casting tube, the vertically positioned casting tube penetrates the bottoms of the crucible and the resistance furnace, and the upturned inlet of the casting tube is positioned over sediment to form a valve seat, which matches a valve body connected with a lifting rod. The smelting crucible provided by the utility model can greatly increase the quality of products and produce high-purity magnesium and magnesium alloy ingots.
Description
(1) technical field:
The utility model relates to a kind of magnesium and magnesium alloy smelting crucible, particularly a kind of downflow system high-purity magnesium and magnesium alloy smelting crucible.
(2) background technology:
At present magnesium factory continues to use artificial pail casting mostly when the casting magnesium ingot, or with the direct casting of tumbler cooperative mechanical, its equipment is more outmoded, is difficult to guarantee magnesium and magnesium alloy purity.Russia and the equipment used of the U.S., its gate spool are that the straight tube under shed inserts in the crucible, melt magnesium liquid with the pump suction, and its gate spool can cause vortex stirring and bring sediment into gate spool when under shed sucks molten magnesium liquid, influence end product quality; Adopt the molten magnesium liquid of pump suction, also produce eddy current, and, increase the weight of sediment and sucked gate spool, influence end product quality by stirring because the pump suction causes vibration.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of downflow system high-purity magnesium and magnesium alloy smelting crucible, can prevent from that crucible bottom sediment is mingled with by stirring to enter finished product, improves end product quality.
For achieving the above object, the utility model adopts following technical proposals:
A kind of downflow system high-purity magnesium and magnesium alloy smelting crucible, comprise the crucible and the gate spool that are placed in the resistance furnace, it is characterized in that the gate spool positioned vertical and pass at the bottom of crucible bottom and the resistance furnace, the gate spool import upwards is positioned on the sediment and constitutes valve seat, valve seat and a valve body coupling, valve body connects a lifting arm.
The upward opening of crucible has the crucible cover by the sealing ring sealing, inserts inert gas inleting pipe from crucible cover.
The utility model has following conspicuous characteristics and advantage compared with prior art: gate spool positioned vertical of the present utility model and import upwards can not stirred sediment and be mingled with and influence product quality when molten magnesium liquid inflow gate spool; Insert inert gas inleting pipe from crucible cover, flow out from gate spool, when the liquid level of molten magnesium liquid is hanged down, can lead to people's inertia gas and pressurize, keep due flow velocity, prevent that gate spool from stopping up at molten magnesium liquid.The melting crucible that adopts the utility model to provide can improve the quality of products greatly, produces highly purified magnesium and magnesium alloy ingot.
(4) scheme attached explanation:
Accompanying drawing is the structural representation of an embodiment of the utility model.
(5) specific embodiment:
A preferred embodiment of the present utility model is: referring to accompanying drawing, the molten refining crucible of this downflow system high-purity magnesium and magnesium alloy includes crucible 24 and the gate spool 13 that is placed in the resistance furnace 21, gate spool 13 positioned vertical and pass 24 ends of crucible and 21 ends of resistance furnace, gate spool 13 imports upwards are positioned on the sediment and constitute valve seat 22, valve seat 22 and valve body 23 couplings, valve body 23 connects a lifting arm 25; One end of the upper end of lifting arm 25 and a lever 2 is hinged, and the middle part of lever 2 is by bearing support 3 supportings, and the other end of lever 2 and a pull bar 1 are hinged.The upward opening of crucible 24 has the crucible cover 5 by sealing ring 4 sealings, inserts inert gas inleting pipe 7 from crucible cover 5.The outlet of an inert gas steel cylinder 12 is connected air inlet pipe 7 through safety valve 11 and pressure regulator valve 10, and Pressure gauge 9 is housed on the air inlet pipe 7; The blast pipe of also pegging graft on the crucible cover 5 has air bleeding valve 6 on the blast pipe.Resistance furnace 21 is supported by support 9; Gate spool 13 is by being placed in the jack 19 on the platform 18 and being with the leg of roller 16 to support; Gate spool 13 outlet sections put lifting cover 14 and are switched to casting mold 15.
