Abstract:
     The invention uses servo crucible to carry on inter mittent feeding and, uses servo crucible linked with grawing crucible to realize simultaneously feeding and drawing. Due to the temp. field in the course of growing is constant, the completeness of crystal is good, transparentness is high, coated matter is less, dimension of crystal is large, so that it can greatly lift up the rate of finished products.
