1. a kind of cold crucible vacuum induction melting device for directionally solidifying of low radial symmetry gradient, including vacuum melting room and trueDirectional solidification room, continuous ingot pulling mechanism, induction power supply, vacuum pump set, cooling system, the control system of empty working chamber'"'"'s connection, itsIt is characterized in:

  • Water jacketed copper crucible, the induction coil around water jacketed copper crucible, and continuous feeding machine are equipped with vacuum melting roomStructure;

    Equipped with crystallizer, crystalline element, the pull bar for drawing crystallizer and providing water route in directional solidification room, and in knotCooler below brilliant device;

    Continuous ingot pulling mechanism provides power that is mobile and rotating below directional solidification room to pull bar;

    The crystalline element is the tubular conduit connected with mouth under water jacketed copper crucible, and its temperature control is attached in the freezing point for the treatment of materialClosely, the environment of solidification is provided for treatment material, the liquid material moved down with crystallizer completes solidifying when by crystalline elementGu process;

    Processing the process of the directional solidification of material is:

    Start induction power supply and convey superaudio electric current to induction coil, electric current is producedElectromagnetic field the furnace charge in crucible is realized smelting in suspension;

    After furnace charge is completely melt, continuous ingot pulling mechanism drawing pull bar simultaneously drivesCrystallizer is moved down, or is moved when rotating;

    The liquid furnace charge carried by crystallizer is moved down therewith, and liquid furnace charge existsSolidified during by crystalline element, be further cooled after cooler is entered;

    Meanwhile, continuous charging mechanism is according to the speed for settingCharging, makes the liquid level in molten bath in crucible keep fixed height, so as to realize continuous directional solidification process.
