The invention discloses an overflow port structure of an ultra-white rolled glass melting furnace in the technical field of glass melting furnaces. The overflow port structure comprises a branch passage, the overflow port is formed in one side of the tail end of the branch passage; the outlet arch is arranged above the overflow port; the first electric boosting piece is arranged at the bottom of the tail end of the branch path and is used for preventing the molten glass from crystallizing; the second electric boosting pieces are arranged on the overflow port pool walls on the two sides of the overflow port and are used for reducing the transverse temperature difference of the molten glass. According to the invention, an electric boosting mode is adopted, and the molten glass at the tail end of the branch path is integrally heated through the first electric boosting piece, so that the temperature of the molten glass at the tail end of the branch path can be increased, and a crystallization phenomenon is prevented; and the second electric fluxing piece is used for locally heating the glass liquid in the overflow port, so that the transverse temperature difference of the glass liquid in the overflow port is reduced, and the uniformity and the glass quality of the glass liquid are improved.

This invention relates to a furnace for producing high-quality photovoltaic glass and a novel overflow outlet for calendering. The furnace includes a furnace pool comprising a melting section, a refining section, a necking section, and a transverse passage connected in sequence. The end of the transverse passage is directly connected to the overflow outlet. In this furnace structure, the transverse passage does not have branch passages; instead, it connects directly to the overflow outlet. This reduces the large lateral temperature difference caused by excessively long branch passages in existing technologies, resulting in low glass melt temperature at the overflow outlet and high temperature in the middle section. It also reduces flow fluctuations caused by excessive bends in the branch passages, thus helping to reduce glass bubble defects. In this furnace structure, the transverse passage is directly connected to one or more overflow outlets, resulting in a small temperature difference between the glass melts at each overflow outlet. This ensures a relatively consistent forming temperature at the calendering stage, facilitating glass forming control.
