How to determine the quality of high-alumina bricks when making your selection
There are many high-alumina brick manufacturers in the market, each claiming their own advantages. However, without the ability to distinguish between good and poor-quality bricks, it’s easy to fall for scams. To help you assess the quality of high-alumina bricks from Zhengzhou-based manufacturers, here’s a simple method for inspection and verification: 1. Check whether the dimensions of the Zhengzhou high-alumina bricks meet the specified requirements and ensure they are consistently uniform in size.

1. Commercial performance optimization of raw materials is a prerequisite for high-quality refractory materials. 2. The production process has evolved from traditional macro-level control to precise micro-level management, shifting focus from material property testing to detailed observation and control of the material's microstructure—this is because the microstructure plays a critical role in determining the material's functional performance. 3. Refractory material packaging technologies are receiving increasing attention, with new packaging methods being continuously adopted. 4. Thanks to advanced techniques such as laser-based inspection and flame spraying repair, furnace linings can now undergo either intermittent or continuous monitoring, as well as regular or irregular maintenance, significantly extending their service life.
