[0002] The tin bath plays an important role in glass production. The molten glass enters the tin bath filled with nitrogen and hydrogen protective gases through the flow channel and the flow trough. The molten metal tin is contained in the tin bath. Since the density of glass is smaller than that of molten tin, the molten glass will float on the surface of the molten tin, similar to oil floating on water. Then, the molten glass will complete the process of natural flattening, thinning, polishing, and cooling, and will be lifted up by the transition roller table to leave the tin bath and enter the annealing furnace for annealing and cooling.

When the tin bath is in use, it is necessary to ensure that the metal tin in the tin bath is in a molten state and the temperature of the molten metal tin is uniform, so as to improve the overall uniformity of the glass plate and reduce glass defects caused by temperature differences. Therefore, a device is needed to achieve lateral temperature difference insulation for the molten metal tin in the tin bath. Utility Model Content
