Abstract
The utility model relates to a metal melting crucible, which comprises a crucible body for containing and melting magnesium alloy, a material feed inlet extending to the bottom of the crucible, and a sealing ring for sealing the mouth of the crucible. The utility model has the advantages of reasonable structure, good sealing performance, configuring alloy, and no use of large quantities of fusing agents; besides, the purposes of combustion resistance and oxidation resistance can be achieved with micro-gases protecting.
Description
The utility model belongs to the crucible that a kind of deposite metal is used.
The present metal molten crucible that uses, for example the fusion crucible of magnesium metal is the crucible of worn-out open type, and the dog-house of projection promptly only is set at the top of crucible, and dog-house and crucible mouth join, and directly throw in magnesium ingot from dog-house, and dog-house seals with the crucible lid.Because the magnesium metal is through can burning and oxidation in air after the heat fused, therefore, below dog-house in the crucible body, flux need be added and gas is made cover layer, to stop the oxidized of magnesium metal.Because the contact frequency and the area of dog-house and air are all bigger, thereby flux that expends and gas flow are also bigger, cause cost to increase, and influence the quality of magnesium liquid.
The purpose of this utility model provides a kind of metal molten crucible that improves structure, makes the oxidized of metal be reduced to a minimum.
The utility model comprises:
A, a crucible body is used for holding and melting magnesium alloy:
B, one extends to the dog-house at the bottom of the crucible;
C, the sealing ring of a sealing crucible mouth.
The utility model is rational in infrastructure, good airproof performance, and the configuration alloy avoids using a large amount of flux, does protection with the gas of trace and has promptly reached fire-retardant and oxidation resistant purpose.
Accompanying drawing is the utility model structural representation.
Be molten into example with magnesium alloy, as shown in the figure, the utility model comprises: a, and a crucible body 1 is used for holding and melting magnesium alloy; B, one extends to the dog-house 2 at the bottom of the crucible; C, the sealing ring 3 of a sealing crucible mouth.
At the bottom of dog-house 2 extended to crucible by commissioning pipe 21 from the crucible top, dog-house 2 added removable cover 22 sealings, 3 sealings of crucible mouth 10 usefulness sealing rings, and the crucible mouth is provided with suction soup mouth 4 and seals.Dog-house 2 uses protective gas SF6 to cover; crucible mouth 10 places use argon gas or other gas to cover; argon gas is charged to crucible mouth 10 with concora crush; after opening removable cover 22 and feeding in raw material; magnesium ingot falls into crucible bottom, and magnesium ingot begins fusing, and magnesium liquid 5 liquid levels are progressively raise; when surpassing dog-house 2 positions, the magnesium liquid 5 in the crucible has been stopped under the protection of argon gas and the contacting of air.Dog-house 2 has adopted less spatial design, and using gases is protected, even it is reinforced often to open dog-house 2, its gas windage is minimum, after employing vacuumizes, charges into protective gas, makes the crucible internal gas pressure value of being maintained fixed, and makes gas lossless, reaches the protection purpose.
The utility model can be used with another utility model of the applicant " magnesium alloy fusing protection stove ", also can be used with existing common melting furnace.
