Description
Technical field
The utility model relates to a kind of vacuum melting furnace, particularly relates to a kind of beryllium copper smelting, ingot casting vacuum melting furnace.
Background technology
Beallon is a kind of precipitation hardening type alloy, it is unique non-ferrous alloy of mechanical performance, physical property, chemical property and etch resistant properties good combination, after solid solution and timeliness heat treatment, there is the high strength limit, elastic limit, yield limit and the fatigue limit suitable with special steel, possess again high conductance, thermal conductivity, high rigidity and wearability, the high erosion performance of wriggling simultaneously, also there is good casting character, non magnetic and no-spark electric conductivity while impacting.
Because beallon possesses many excellent properties, its use is more and more extensive, has become indispensable essential industry material in the development of the national economy.External beallon is mainly used in car electrics manufacture, computer and telecommunication industry.In addition, beallon also has a wide range of applications in industries such as Aero-Space, household electrical appliance, electronic instrument, machinery, submarine cable, oil, coals
But, due to some characteristics of beryllium, in copper, add after a small amount of beryllium, compared with conventional copper alloy (as red copper, brass etc.), there is huge change in its character, be embodied in the problems such as hard state effect is obvious, smelting temperature raising, fluidity of molten variation, the casting of beallon all adopts conventional casting mode at present simultaneously, in casting cycle due to beryllium copper oxidation, cause that foundry goods is inner easily to be formed loose, cavity and the various casting flaw such as be mingled with, thereby have a strong impact on follow-up pressure processing and machining.
Summary of the invention
The purpose of this utility model is to solve the defect that prior art exists, and a kind of beryllium copper that provides a kind of melting and cast all to carry out under vacuum state is smelted, ingot casting vacuum melting furnace.
The technical solution of the utility model is: a kind of beryllium copper is smelted, ingot casting vacuum melting furnace, comprise vacuum melting furnace body, vacuum extractor, electrical control gear, the melting kettle that it is characterized in that being placed in body of heater is by crucible, be wrapped in the heater outside crucible and be enclosed within the shell body composition on heater, in shell body both sides, correspondence position is provided with short supporting axle, melting kettle is arranged on the support in body of heater by the short supporting axle of both sides, wherein the short supporting axle of a side is connected with connecting axle one end, the connecting axle other end is connected with whirligig through body of heater, between connecting axle and body of heater, adopt rotatable being tightly connected, be sidelong the mould that is equipped with cast use at melting kettle one, in upper of furnace body, the agitating device for the material in melting kettle is stirred is installed.
The above-mentioned whirligig being connected with connecting axle is rotary handle or motor.
The temperature measuring equipment of measuring temperature in melting kettle is installed on above-mentioned body of heater.
Above-mentioned agitating device is magnetic stirring apparatus.
The utility model adopts the integrated technology that carries out melting, casting in vacuum melting furnace, in smelting process, pass through the stirring to liquation simultaneously, can make the impurity floating in beryllium copper solution, improved the uniformity of various elements in liquation simultaneously, can effectively prevent beryllium copper oxidation in casting cycle that antivacuum casting that prior art adopts brings, the problems such as the inside ingot defect that causes is many, density is poor, effect has improved the lumber recovery of beryllium copper ingot casting post-production, cuts down finished cost.
Adopt the technical solution of the utility model, the density of the ingot casting that obtains is between 96%～98%, and grain size is between 40～80 μ m, and maximum internal defect (empty be mingled with) is less than 10mm.Above-mentioned technical indicator is far longer than the corresponding technical indicator of the ingot casting of prior art production, and because internal flaw is little and less, the lumber recovery in process is more than 70%, higher than 50% left and right of prior art, a ton processing cost can reduce more than 30% simultaneously.
