1、 Equipment Description:
1. This equipment is mainly used for continuous casting of single crystal copper bars, single crystal silver bars, and single crystal gold bars, and can also be used for continuous casting production of other metals and alloys
2. This equipment is a vertical furnace body. The raw materials, crucible, and crystallizer are placed in the furnace cover opened from the top, and the crystallization guide rod is placed in the lower part of the furnace body. First, the crystal is pulled out of the melt by a certain length through the crystallization guide rod, and then the crystal rod is fixed on the winding machine for drawing and collection.
3. This device adopts a touch screen fully automatic control system with multiple monitoring devices to accurately control the temperature of the furnace and crystallizer, achieving the long-term stable conditions required for crystal growth; Multiple protective actions can be performed through monitoring equipment, such as material leakage caused by high furnace temperature, insufficient vacuum, water under pressure or shortage, etc. The equipment is easy to operate, and the main parameters set include furnace temperature, temperature of the upper, middle, and lower parts of the crystallizer, pre pulling speed, crystal growth pulling speed (as well as inch mode, which means pulling for a period of time and stopping for a period of time), and various alarm values.

3、 Main structural description:
1. Furnace body: The furnace body adopts a vertical double-layer water-cooled structure. The furnace cover can be opened for easy insertion of crucibles, crystallizers, and raw materials. There is an observation window on the upper part of the furnace cover, which can observe the condition of the molten material during the melting process. Induction electrode flanges and vacuum pipeline flanges are symmetrically arranged at different height positions in the middle of the furnace body to introduce induction electrode joints and connect with the vacuum unit. The furnace bottom plate is equipped with a crucible support frame, which also serves as a fixed pile to accurately fix the position of the crystallizer, ensuring that the center hole of the crystallizer is concentric with the sealing channel on the furnace bottom plate. Otherwise, the crystallization guide rod will not be able to enter the interior of the crystallizer through the sealing channel. There are three water-cooled rings on the support frame, corresponding to the upper, middle, and lower parts of the crystallizer. The temperature of each part of the crystallizer is precisely controlled by controlling the flow rate of cooling water. There are four thermocouples on the support frame, which are used to measure the temperature of the upper, middle, and lower parts of the crucible and crystallizer, respectively. The interface between the thermocouples and the outside of the furnace is located on the furnace bottom plate. A discharge container can be placed at the bottom of the support frame to prevent the melt temperature from flowing directly down from the cleaner and causing damage to the furnace body. There is also a detachable small coarse vacuum chamber in the center position on the bottom plate of the furnace. Below the coarse vacuum chamber is an organic glass chamber that can be added with an anti-oxidation agent to improve the vacuum sealing of the fine wire. The material can achieve the anti oxidation effect on the surface of the copper rod by adding an anti-oxidation agent to the organic glass cavity.
2. Crucible and Crystallizer: The crucible and crystallizer are made of high-purity graphite. The bottom of the crucible is conical and connected to the crystallizer through threads.
3. Vacuum system:
1. Roots pump
2. Pneumatic high vacuum disc valve
3. Electromagnetic high vacuum inflation valve
4. High vacuum gauge
5. Low vacuum gauge
6. Furnace body
7. Pneumatic high vacuum baffle valve
8. Cold trap
9. Diffusion pump
4. Drawing and winding mechanism: The continuous casting of copper bars consists of guide wheels, precision screw rods, linear guides, and winding mechanisms. The guide wheel plays a guiding and positioning role, and the first thing the copper rod passes through when it comes out of the furnace is the guide wheel. The crystallization guide rod is fixed on the precision screw and linear guide device. The copper rod is first pulled out of the furnace body (pre pulled) through the linear motion of the crystallization guide rod. When the copper rod passes through the guide wheel and has a certain length, the connection with the crystallization guide rod can be cut off. Then it is fixed on the winding machine and continues to draw the copper rod through the rotation of the winding machine. The servo motor controls the linear motion and the rotation of the winding machine, which can precisely control the continuous casting speed of the copper rod.
5. The power system's ultrasonic power supply adopts German IGBT, which has low noise and energy saving. The well uses temperature control instruments for programmed heating. Electrical system design
There are overcurrent, overvoltage feedback and protection circuits.
6. Control system: This equipment adopts a touch screen fully automatic control system with multiple monitoring devices to accurately control the temperature of the furnace and crystallizer, achieving the long-term stable conditions required for copper rod continuous casting; Multiple protective actions can be performed through monitoring equipment, such as material leakage caused by high furnace temperature, insufficient vacuum, water under pressure or shortage, etc. The equipment is easy to operate and the main parameters are set
There are furnace temperature, temperature of the upper, middle, and lower parts of the crystallizer, pre pulling speed, and crystal growth pulling speed
And various alarm values. After setting various parameters, in the production process of copper rod continuous casting, as long as safety is ensured
Place the crystallization guide rod, place the raw materials, close the furnace door, cut off the connection between the copper rod and the crystallization guide rod, and connect it to the winding machine.
