[0002] With the improvement of float design level and the progress of refractory production technology, float glass melting furnace is developing towards large scale and high furnace age. At present, the domestic float glass melting furnace design furnace age is generally 8~12 years, and the high level glass furnace age abroad has reached 15~20 years, so the gap between the two is very large. Besides the difference in the production technology level of melting furnace refractory materials from foreign countries, the service life of L-shaped hanging wall is also an important "bottleneck" restricting the furnace age.

[0003] The use environment of the feeding port of the float glass melting furnace is relatively poor. Therefore, the L-shaped hanging wall as a separation device of the feeding port also has high technical requirements. First, the temperature of the feeding port area is high, and the hanging wall needs to have high high-temperature corrosion resistance. Second, due to the need for sealing and separation, the L-shaped hanging wall needs to be pressed low, so the flame baffle brick of the L-shaped hanging wall is close to the aggregate pile, which is easy to bond the aggregate, so the nose area of the hanging wall needs to have high aggregate corrosion resistance. In addition, due to the effect of the horizontal flame furnace, there is a large pressure difference between the normal combustion and the small furnace injection interval in the furnace, thereby forming the phenomenon of alternating wind and fire in the nose area of the hanging wall, which requires the refractory material in the nose area of the hanging wall to have strong anti-quenching and anti-thermal performance.

[0004] Therefore, in the float glass production practice, the flame baffle brick of the L-shaped hanging wall is the vulnerable part of the hanging wall, which is prone to breakage, and if not replaced in time, it will affect the internal pressure and atmosphere of the melting furnace, and further affect the glass melting quality.
