Refractory Ball
Low creep refractory balls are spherical refractories with relatively low creep rate in high temperature environments.

High-alumina refractory balls are subdivided into 60, 70, 80, 85, 90 and other series according to the alumina content, and can be divided into 20mm, 25mm, 30mm, 40mm, 50mm, 60mm refractory products in the shape of balls according to the size. The Al2O3 content is between 70-86%, and other components such as Cr2O3, ZrO2, and Fe2O3 also have clear requirements.

Siliceous refractory balls are refractory sphericals with silica as the main component, siliceous refractory balls belong to acid refractory materials, and the main component is silicon dioxide (SiO2), and the content is usually more than 92%. These materials are highly resistant to acidic slag but are susceptible to alkaline slag.
