1. “Refractory production status and challenges: the key role of mixer blade technology”
Refractory materials are critical in industries like metallurgy, glass, cement, and ceramics, excelling under extreme heat, pressure, and corrosive conditions. However, traditional production methods and blade designs struggle with complex raw material mixing, uneven blending, and poor wear resistance—limiting efficiency and quality.
The mixer blade is a vital component directly impacting refractory performance. Conventional blades fail in high-temperature, abrasive environments.
Â
ZZ Craftsman’s vacuum-brazed carbide-steel mixer blades solve this. Tungsten carbide delivers superior wear resistance and thermal stability, while steel provides toughness and strength. Vacuum brazing perfectly bonds them, eliminating weaknesses and enhancing durability, mixing uniformity, and service life—significantly boosting production efficiency and refractory quality.

2. Analysis of vacuum brazing technology of cemented carbide and steel: why it has become the new favorite in the refractory materials industry
With industrial advancements and rising market demands, the refractory industry is embracing vacuum-brazed carbide-steel mixer blades as a breakthrough innovation. This technology combines cemented carbide’s extreme hardness and wear resistance with steel’s toughness and strength, creating blades that excel in high-temperature, abrasive mixing environments—delivering superior durability, uniformity, and extended service life.
Zhuzhou Old Craftsman optimizes performance through three critical factors:
*Carbide Grade Selection: Refractory raw materials (hexamine, graphite, resin, alumina, magnesite) reach 9 Mohs hardness. Selecting the right carbide grade prevents rapid wear and ensures longevity.
**Vacuum Brazing vs. High-Frequency: While high-frequency brazing is cheaper, it causes cracking, quality loss, and carbide detachment. Vacuum brazing eliminates oxidation and internal stress, ensuring zero fallout and consistent performance, despite higher cost and complexity.
***Innovative Design: Minor shape adjustments—based on customer feedback—have doubled blade lifespan, proving that smart design amplifies material advantages.
These blades significantly enhance mixing efficiency, refractory quality, and production stability. As vacuum brazing technology evolves, it will play an increasingly vital role in modern refractory manufacturing, driving efficiency, reducing downtime, and meeting stringent quality standards.
