In the high - temperature refractory materials industry, fused white corundum has emerged as a crucial component due to its excellent high - temperature resistance and chemical stability. This article serves as a comprehensive guide for procurement and engineering technicians in the high - temperature refractory materials field, focusing on how to optimize the performance of refractory materials through proper fused white corundum particle size selection.
Fused white corundum comes in a wide range of particle sizes, from fine powders to coarse aggregates. Each size fraction plays a unique role in determining the performance and service life of refractory materials. A well - managed particle size distribution can significantly enhance the construction performance and service life of refractory products.
For example, in a study of European and American customers, it was found that in a typical steel - making electric arc furnace, the right combination of fine and coarse fused white corundum particles can increase the density of the refractory material by up to 15%, which in turn improves its resistance to high - temperature erosion and mechanical wear.
"The proper selection of fused white corundum particle size is like the foundation of a building for refractory materials, directly affecting its overall performance and longevity," says a senior engineer from a well - known refractory materials company.
Another important factor in fused white corundum is particle morphology, mainly spherical and irregular particles. These two types of particles have distinct physical properties and different applications in refractory products.
Spherical particles of fused white corundum offer excellent fluidity. In ramming masses, spherical particles can fill the gaps between larger particles more effectively, improving the overall density of the material. According to European customer data, ramming masses with spherical particles can achieve a fluidity improvement of about 20% compared to those with irregular particles. This improved fluidity leads to better construction performance, reducing the time and effort required for installation.
Irregular particles, on the other hand, have a stronger interlocking effect. In precast bricks, irregular particles can enhance the mechanical strength and anti - spalling ability of the bricks. In a catalytic cracking reactor application, precast bricks made with irregular particles showed a 25% reduction in spalling rate compared to those made with spherical particles, ensuring a longer service life under harsh operating conditions.
To select the most suitable fused white corundum particle size, it is essential to consider the specific working conditions of the refractory material. In a kiln, for example, the temperature gradient and thermal stress distribution vary significantly. Based on this, we can provide the following particle size selection suggestions:
