Description
Technical field
The utility model relates to monocrystalline orientation hot investment casting furnace more particularly to a kind of monocrystalline orientation hot investment casting furnace clamping dresses
It sets.
Background technique
Directional solidification refers in process of setting using compulsive means, makes solid-liquid circle of the casting in entire process of setting
Hot-fluid on face should keep spreading from a direction, i.e. oriented heat dissipating, while positive temperature must be maintained in crystallization front region
Gradient provides the temperature gradient on single direction during metallic crystal, eliminates in crystallization process to prevent new nucleus from being formed
The transverse grain boundaries of generation significantly improve the ability to work of casting at high temperature, grow crystal along this direction as far as possible, make to cast
Part has the column crystal or single crystal organization structure of single direction.
Directional solidification is a technology being of great significance in casting, it is mainly for the manufacture of gas turbine hot-end component
High temperature alloy part, the especially turbo blade of aerospace engine.This kind of blade working is in bearing temperature highest, stress
Under most complicated, the worst environment of environment, it is considered as most important part in engine critical material.The property of turbine rotor blade
The horizontal especially temperature capability of energy is the important symbol of aero-engine performance, and directional solidification casting is exactly to improve engine whirlpool

The charging work of smelting period, traditional feed way are completed in the charging that monocrystalline orients hot investment casting furnace by feed compartment
For the material rod cavity body for clipping base material is carried out vacuumize process with clamp, is then opened between connection working chamber and feed compartment
Balanced valve reaches the vacuum pressure in two spaces unanimously, to can just open isolation gate valve between the two, completes to add
Material movement, masterbatch complete fusing and casting work in working chamber, wait casting to terminate to feed by feed compartment again, in cycles
Charge-melting-comes out of the stove movement.
Scene is different in melting situation, it is sometimes necessary to the mating crucible lining of one, a furnace master alloy, sometimes again
It needs several furnaces or more than ten furnace master alloys to replace crucible lining again, smelts steel grade and weight due to need to often replace, then it can constantly more
Crucible specification and master alloy specification are changed, causes the charging of monocrystalline orientation hot investment casting furnace and replacement crucible lining that two sleeve clamps is divided to be used for
The master alloy and crucible lining of different size are accommodated,
At present at present to vacuum precision foundry furnace charging and replacement crucible be divided to two sleeve clamps, meanwhile, charging and replace
Crucible device is under high temp/high pressure environment for a long time, is replaced fixture every time and is obtained vacuum breaker first, vacuum degree is waited to get off to reach
Under normal pressure, equipment cooling is also needed to wait for, extends the stand-by time of equipment entirety, production efficiency substantially reduces, and high-temperature operation
Also it is easy to cause unexpected injury to execute-in-place worker.
Therefore, how a kind of monocrystalline orientation hot investment casting furnace clamp device is provided, bar and any, crucible be both able to satisfy
Fixture problem with size, but can solve vacuum breaker in smelting process, vacuumize, cool down waiting time problem, save smelt etc.
To the time, to reduce production process and equipment adjustment time, improving production efficiency and automatization level becomes art technology
Personnel's important technological problems urgently to be resolved.
