[0002] In the production process of photovoltaic glass, after the glass liquid is melted in the kiln, the glass liquid is transported to the calender through the lip brick. The calender forms and rapidly cools the glass liquid, and then the glass plate is transported to the annealing furnace through the transition roller table for annealing. After the annealing is completed, the glass plate is cut and packaged after being transported to the cold end, and the production is completed.
[0003] After the glass liquid flows out of the kiln, it first forms a molten pool on the lip brick, and then stably provides the glass liquid to the calender.

In order to stabilize the width of the glass pool, a side brick is arranged on the upper side of the lip brick on both sides to determine the width of the glass pool.
[0004] The glass liquid at the edge is blocked by the side brick and exchanges more with the external environment, so the temperature drops quickly. The temperature loss of the side brick is easy to cause crystallization, which produces a series of defects and greatly affects the production quality of the glass. CONTENT OF THE INVENTION
