Glass melting furnaces are the core of glass production, and their upper structures face severe challenges from high temperatures, alkaline vapor erosion, and temperature fluctuations. Therefore, selecting the right refractory bricks is crucial for kiln operation.
1. The superior performance of magnesia-chrome refractory bricks
Magnesia-chrome bricks are mainly composed of magnesium oxide and chromium oxide, and they have excellent comprehensive properties.
Magnesia-Chrome Fire Brick
(1) High high temperature strength and high load softening temperature
Magnesia-chrome bricks possess extremely high high-temperature strength and load softening temperature, enabling them to withstand working temperatures exceeding 1600°C in the upper structure of glass melting furnaces.
(2) Strong resistance to erosion
The presence of chromium oxide significantly enhances the ability of magnesia-chrome bricks to resist erosion by alkaline vapors and sulfur oxides. This is crucial for extending the lifespan of the kiln.
(3) Good thermal shock stability
Magnesium chrome refractory bricks have good thermal shock resistance, which can effectively reduce structural spalling caused by temperature fluctuations, thereby maintaining the overall integrity of the kiln.
2. The key role of magnesia-chrome bricks in the upper structure of kilns
Because of these characteristics, magnesia-chrome bricks have become an ideal choice for the upper structure of glass melting furnaces.
glass melting kiln
Specifically, it refers to key parts such as the breast wall and the main arch of the kiln. These areas are directly exposed to the corrosive effects of high-temperature flames and volatile components; using magnesia-chrome bricks can create a strong barrier.It not only reduces structural damage caused by erosion, but also lowers the risk of kiln shutdowns for maintenance due to brick damage.
Meanwhile, compared with refractory bricks made of other materials, magnesia-chrome bricks exhibit a more outstanding service life under these harsh environments.
3. Comprehensive considerations: From manufacturer to price selection
The price of refractory bricks is an important reference when purchasing, but simply comparing the unit price may lead to increased maintenance costs later on.
A reliable refractory brick supplier will provide the most suitable material solution based on the specific kiln conditions of the customer, thereby helping the customer maximize their return on investment.
For glass companies, choosing a partner that can provide high-quality refractory bricks and respond promptly is essential to achieving overall cost optimization.
