ABSTRACT:
A crystal-growing furnace having a slurry drainage duct structure includes a furnace body, a supporting table, a loading frame, a plurality of eaves elements, and a set of eaves gutters. The supporting table includes a table plate and a plurality of supporting posts. The loading frame includes a lower plate and four side plates, where four elongated eaves boards descend from sides of the lower plate. Four eaves gutters, having V-shaped grooves, are connected with one another and disposed beneath the four eaves elements correspondingly. Any high-temperature silicon slurry leaks from a furnace crucible will be guided by the elongated eaves boards into the V-shaped grooves of the eaves gutters to prevent the silicon slurry from flowing along the periphery of the table plate and down to the supporting posts.
