Fire-resistant glass has good light transmittance and flame retardant properties. The demand for fire-resistant glass in Ningxia is also increasing. Fire-resistant glass can effectively improve the level of construction.

[0003] The fireproof glass tempering furnace is the core equipment for producing tempered glass, and the wind chamber of the tempering furnace is a key component to ensure the heating and cooling quality of the tempered glass. The wind chamber provides an efficient wind field for the heating and cooling of the tempered glass, which can not only ensure that the tempered glass is heated quickly and evenly, but also reduce the energy consumption of the fan. The cross-section of the original wind chamber is a trapezoidal structure. Although it can balance the wind pressure of the wind chamber, it is impossible to ensure the balance of wind pressure in a large-sized wind chamber due to the limitation of the structural size of the wind chamber. Therefore, the utility model proposes a wind chamber of a tempering furnace. Utility Model Content
