Recently, the refractory materials industry has been accelerating its transformation toward intelligence and customization. Relying on more than two decades of R&D and production expertise in refractories, Zhengzhou Zhenda Refractories Co., Ltd. continues to launch a range of products, including high-alumina refractory bricks, amorphous castables, refractory cements, and insulation materials, while also offering integrated kiln construction services, steadily expanding its market presence in high-temperature industries such as metallurgy, carbon, and cement.

Recently, the refractory materials market has been steadily recovering, and as a fundamental consumable in high-temperature industries, refractory bricks are seeing continued improvements in their market demand structure.

Recently, China’s refractory materials and refractory brick industries have exhibited a pronounced structural divergence. Competition in the conventional, standard refractory brick market has intensified, with outdated production capacity continuing to be phased out. Meanwhile, high‑temperature kilns in the steel, cement, nonferrous metals, and new‑energy sectors are steadily increasing demand for long‑life, thermal‑shock‑resistant, low‑carbon refractory bricks, shifting the industry’s focus from mere capacity expansion to materials R&D and integrated, end‑to‑end service solutions.

What determines the wear resistance of firebricks?
The wear resistance of refractory bricks is influenced by temperature. For instance, certain refractories—such as high-alumina bricks—are generally believed to exhibit lower wear resistance at higher temperatures (specifically within their elastic range, typically below 700–900°C). This means that as the temperature rises and the refractory’s elastic modulus increases, its wear resistance tends to decline. However, once the temperature reaches a point where the elastic modulus peaks, further decreases in the modulus actually lead to improved wear resistance. For example, clay bricks demonstrate significantly better wear resistance at 1200–1350°C compared to room temperature conditions. Yet, if the temperature continues to rise beyond 1400°C, the rapid drop in viscosity of the liquid phase within the refractory material causes wear resistance to diminish again. On the other hand, some refractory materials—like chromium-containing refractories—actually show enhanced wear resistance as temperatures increase.

Which refractory bricks can extend the service life of a converter steelmaking process?
To extend the service life of a converter, the lifespan of the refractory brick lining—known as the "converter village"—is directly influenced by its own durability. This can be broadly divided into two key aspects: First, operational conditions cannot be altered arbitrarily; they depend on the production processes and product-specific manufacturing routes, as well as the expertise of the operators. Second, implementing effective maintenance techniques—including regular inspections and repairs—and employing advanced furnace protection methods can significantly enhance the longevity of the furnace lining.
