Tellurium Automatic Refining and casting Furnace TARCF
TARCF is used for produce refined Tellurium in block after refining and improve the impurities
After drying in dryer, the tellurium flakes (powder) are manually fed into the crucible and placed into the melting furnace for heating, melting and impurity removal after which the crucible is dumped and the liquid tellurium is poured into the mold for casting. the Special made mold ,after slag removal on the ingot turntable automatically rotates to complete the subsequent tellurium ingot casting in sequence. When the turntable rotates to a designated station, the mold is mechanically knocked down and it starts to automatically demold the tellurium ingot that is manually clamped to complete the stacking process. These unqualified tellurium ingots are automatically removed and returned to the melting furnace for repeated production until qualified .
Main Functions and Technical Features
PLC control system
① Unique Design of crucibles and its poring chute has long life, fast heat conduction, and no pollution to the liquid.
② The furnace and crucible are divided into temperature measurement and control zones, and the solution temperature can also be indirectly controlled by the temperature of one furnace.
③ When the furnace or liquid is overheated, the thermocouple fails and the system automatically sounds and lights an alarm.
④ Automatic 15.5-inch color human-machine interface touch screen ,Programmable parameter input and output, alarm information;
⑤ Ensured stability on production process With K-type high-quality ceramic thermocouples to control temperature with accuracy within ±5℃;
⑥ Equipped with PID power regulator heating control to effectively prevent the furnace temperature drift that increases the heating element service life ; Real-time furnace split pouring control function, intuitive and easy to control
