A crucible body of the crucible is formed from a cylindrical wall and a crucible bottom which is connected with the cylindrical wall into integration, wherein, the bottom of the crucible body is provided with a U-shaped draft tube of which one end is provided with a stem bar extending out of the bottom of the crucible body, and the lower end of the stem bar is provided with a nozzle. The crucible has the advantages that the outflow velocity of fused masses can be effectively controlled, the operation is convenient, and the phenomenon of furnace leakage can not be generated.
Description
The utility model relates to the crucible that is applicable to that effective control melt is supplied with.
Crucible is the common equipment of smelting metal, alloy, glass etc., but some occasion needs to make by the flow export at the end melt to flow out, and the crucible that the speed of melt outflow again can be controlled.For example when the preparation quick setting flat alloy welding wire, just need this crucible.
Reported the production technology and the device thereof of non-rolled catalyst alloy for artificial diamond among the Chinese patent literature CN1161883A (application number 96115208.1), its device is seen Fig. 4.The crucible of used a kind of melting catalyst alloy band is that top is cylindrical in this device, the bottom is the rectangular platform body of the similar shape of falling isosceles of interior sky, on the platform body, be provided with the rectangle spray orifice, the width of its spray orifice is 0.1～0.8 millimeter, and spray orifice is 0.2～2.5 millimeter apart from the distance on chill roll surface.This crucible is made by quartz, and the top of crucible is equipped with the inert gas gas ducting.Can produce the catalyst alloy band with this crucible.But because the spray orifice of this crucible is the spray orifice that is directly installed on the straight-run of pipe formation of crucible bottom, reliability is not high, and the melt that do not pressurize sometimes also can leak out, and the runout phenomenon takes place easily.
Chinese patent literature CN1062861A has reported the vacuum metal spray and has revolved the prevention of leakage method and system.Its system and device is seen Fig. 5.The crucible that a kind of melt can flow out from its bottom has been described in its system.This crucible has a crucible body, and there is a spray orifice that is formed by straight tube the lower end of crucible body, crucible body suitable for reading a sealed cavity is arranged, and is provided with heat-resisting silicon rubber vaccum seal ring between crucible body and the seal chamber.A pipeline is arranged on sealed cavity.This crucible also can be used for the production of metal band.But, because spray orifice is an aperture of crucible bottom, control the rate of outflow of melt, so be difficult for the effectively flow velocity of control melt, the leakage that equally also is easy to produce melt with pressure P 2 balances of pressure P 1 in the crucible and crucible outer container.
The purpose of this utility model just is to develop a kind of runout phenomenon of avoiding taking place, again a kind of novel crucible that can effectively control the melt supply of easy operating.
Of the present utility modelly a kind ofly can effectively control the crucible that melt is supplied with, constitute crucible body 6 at the bottom of the crucible that fuses by cylindrical wall with cylindrical wall.U type mozzle 7 is housed in the bottom of crucible body 6, at an end of U type mozzle 7 stem bar 9 that stretches out crucible body 6 bottoms is arranged, there is spout 32 lower end of stem bar 9.
Said crucible body 6 constitutes good with the cylindrical wall that has circular base.In order in the process of supplying with metal, alloy melt, to provide pressure to keep the chamber, on 6 mouthfuls of crucible bodies, a crucible gland 22 is installed, air inlet pipe 33 and pressure vacuum gauge 34 are housed or/and thermocouple and sleeve pipe 2 thereof on the crucible gland.
For crucible gland 22 and crucible body 6 are well sealed, between 6 mouthfuls of crucible gland 22 and crucible bodies, sealing ring 21 is housed.In order to make crucible body 6 and crucible gland 22 tightr, again better with smelting furnace for example intermediate frequency furnace be connected, bolt hole 35 is arranged on crucible gland 22, by bolt 23 crucible gland 22 is linked to each other with the parts of smelting furnace.
Stem bar 9 fuses with U type mozzle 7, said stem bar 9 fuses with U type mozzle 7, be U type mozzle 7 and stem bar 9 to be made an integral body or made U type mozzle 7 with a kind of material with a kind of material, make stem bar 9 with above-mentioned same material or with different materials again, again with commercially available high-temp glue for example Ludox it is bonded together.U type mozzle 7 with or the mode of stem bar 9 by screw thread or bonding be connected with the bottom of crucible body 6, so promptly saved stopper rod, simplified apparatus structure, can guarantee again runout does not take place in the process of melting, could flow out crucible body 6 because melt 8 has only by the effect of air pressure.Crucible body 6, U type mozzle 7 and stem bar 9 can with quartz, graphite, metal for example platinum and the pottery for example a kind of material wherein such as boron nitride, zirconia make.The spout 32 of said stem bar 9 can be 1-60 spout side by side, is good with 1-10 again.Spout 32 is wherein a kind of of circular, square, rectangle.The diameter of circular spout is the 0.05-20 millimeter, and the length of side of foursquare spout is the 0.05-20 millimeter, and the rectangle width of jet is the 0.05-3 millimeter, long 0.06-200 millimeter.
The utility model can use in atmospheric environment, also can use in vacuum environment.For when vacuumizing, the eliminating that magnetic valve 20 is opened for the gas in the crucible body 6 provides new passage, to accelerate the rising of the vacuum in the crucible body 6, a magnetic valve 20 is installed on crucible gland 22.
Of the present utility model effectively to control a kind of mode that crucible that melt supplies with uses be that crucible of the present utility model is installed in (see figure 3) in the flat alloy welding wire spray to cast device, with raw material soldering wire alloy ingot Ag for example
5Cu
