High alumina refractory bricks are a type of neutral refractory material known for their excellent performance. They can withstand high temperatures, chemical corrosion, and mechanical stress. In the market, Zhengzhou Kerui (Group)'s high alumina refractory bricks stand out. These bricks contain a high percentage of alumina, typically around 48% - 80%, which gives them superior refractoriness and thermal stability.
Zhengzhou Kerui (Group) pays great attention to quality control in the production of high alumina refractory bricks. Firstly, they select high - quality raw materials. The alumina raw materials are sourced from reliable mines, ensuring high purity. During the production process, strict process control is implemented. For example, the mixing ratio of raw materials is precisely controlled. The forming process uses advanced technology to ensure the density and uniformity of the bricks. The firing temperature is also carefully regulated, usually ranging from 1400°C to 1700°C, which guarantees the high strength and refractoriness of the bricks.
However, many other manufacturers may not have such strict quality control. Some may cut corners on raw materials or have unstable production processes, resulting in inconsistent product quality. In contrast, Zhengzhou Kerui's high alumina refractory bricks have a low rejection rate, less than 5%, which is much lower than the industry average of around 10%.
| Product | Refractoriness | Thermal Conductivity | Price (Relative) |
|---|---|---|---|
| Zhengzhou Kerui High Alumina Bricks | 1700°C - 1800°C | 1.2 - 1.5 W/(m·K) | Medium |
| Competitor A's Bricks | 1600°C - 1700°C | 1.5 - 1.8 W/(m·K) | High |
| Competitor B's Bricks | 1500°C - 1600°C | 1.8 - 2.0 W/(m·K) | Low |
As shown in the table, Zhengzhou Kerui's high alumina refractory bricks offer a good balance between performance and price. Although Competitor B's bricks are cheaper, their refractoriness and thermal conductivity are not as good as Zhengzhou Kerui's. Competitor A's bricks have better performance but come at a relatively high price. In general, Zhengzhou Kerui's products provide high cost - performance for customers.
In the industry, customers often face some pain points. For example, some industries require refractory bricks with high resistance to chemical corrosion, while others need bricks with low thermal conductivity to save energy. Zhengzhou Kerui (Group) can provide customized solutions. They can adjust the composition and production process of the bricks according to different customer needs. For instance, for customers in the chemical industry, they can increase the content of certain elements in the bricks to enhance chemical corrosion resistance.
Another pain point is the long - term supply and after - sales service. Zhengzhou Kerui has a stable production capacity and can ensure long - term supply for large - scale projects. They also have a professional after - sales service team that can quickly respond to customer problems and provide on - site technical support if necessary.
