Selection of passage pool wall bricks near the neck outlet of photovoltaic calendering glass melting furnace

The selection of passage pool wall bricks near the neck outlet of photovoltaic calendering glass melting furnace is a critical and complex engineering task involving multiple considerations. These factors include the working environment of the glass melting furnace, the corrosion resistance of the material, thermal stability, and mechanical strength. Below we will discuss in detail how to select suitable passage pool wall bricks to ensure the normal operation and extended service life of the melting furnace.

First of all, considering the high temperature environment near the neck outlet of the photovoltaic calendering glass melting furnace, the passage pool wall bricks must have good high temperature resistance. This means that the selected material should be able to withstand the high temperature in the melting furnace without deformation, melting or cracking. Generally, high-alumina refractory bricks and silica refractory bricks are widely used because of their excellent high temperature resistance.

Secondly, corrosion resistance is also a key factor to consider when selecting passage pool wall bricks. There may be various corrosive gases and chemicals in the melting furnace, so the selected material should be able to resist these corrosive effects and maintain its structural integrity and stable performance. In this regard, some specially proportioned refractory materials are favored for their excellent corrosion resistance.

In addition, mechanical strength is also an aspect that cannot be ignored. The passage pool wall bricks need to withstand the scouring of the flowing glass liquid inside the melting furnace and the mechanical force, so they must have high compressive strength and flexural strength. By selecting refractory materials with excellent mechanical properties, it can be ensured that the passage pool wall bricks are not easily damaged during use, thereby maintaining the stable operation of the melting furnace.

In summary, when selecting the passage pool wall bricks near the neck outlet of the photovoltaic rolled glass melting furnace, it is necessary to comprehensively consider multiple factors such as high temperature resistance, corrosion resistance and mechanical strength. By selecting suitable materials, the normal operation of the melting furnace can be ensured and the service life can be extended, thereby improving the efficiency and quality of photovoltaic rolled glass production.
