Refractory Ceramic Ball Description
Refractory Ceramic Ball is made from industrial alumina and other raw refractory materials, which are then mixed, shaped, and fired. It has the following features: 1. High strength and long service life; 2. High chemical stability; and 3. Excellent resistance to high temperatures up to 1900 degrees. It can be used as support and covering packings for catalysts in converters, reformers, desulfurizes, and methanation, and can also be used as packings in hot blast heaters and heat transformers in the iron and steel industries.
