Process to separate impurities from molten tin in a float bath for the production of float glass

摘要

#CMT# #/CMT# In a process to separate impurities from molten tin in a float bath for the production of float glass, the liquid tin is drained from the bath at a location where the temperature is at least 600[deg] C. The liquid tin is then fed through a settling duct at a speed between 0.0005 cm/s and 0.3 cm/s. The cleaned tin is then returned to the float bath. #CMT#USE : #/CMT# Process to separate impurities from molten tin in a float bath for the production of float glass. #CMT#ADVANTAGE : #/CMT# The process removes iron better than prior art and combines simplicity with low cost. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of the assembly. 1 : Cylindrical mantle 2 : lid 3 : countersunk base 4 : aperture 5 : screw 6 : clamp ring 7 : tube 8 : outlet.
