Abstract: PURPOSE: A device and a method for continuously casting high purity silicon are provided to prevent impurity contamination from a crucible by protecting the inner wall of the crucible made of copper or copper alloy with a solid silicon lining. CONSTITUTION: A silicon shell corresponding to a crucible lining is formed on the inner wall of a crucible(2) using a plasma torch(1) as a first fusion for preventing the impurity contamination from the crucible made of copper. A fusion and a refining are generated on the center unit using the plasma torch with low power as a second fusion. A tap is generated on the lower side of the opened crucible with the direct cooling. A sound casting is performed by applying the vibration to a dummy bar and solidified silicon.
