Catalyst Bed Support Media

First、performance characteristics and uses of
Fire-resistant ball on industrial alumina, the main raw material for refractory clay, the scientific formula in shape, from high-temperature calcination. It has: 1, chemical stability, and do not react chemically with the material. 2, high mechanical strength, the use of long cycle. 3, high temperature performance, and the highest heat-resistant temperature can reach 1,900 degrees Celsius. Particularly applicable to high and low temperature transform fertilizer plant furnace, converting furnace, pushing plate from the kiln ball of gas-liquid dispersion and support, cover and protect the role of a catalyst, can also be used for the steel industry transform the hot stove and heating equipment. Refractory ball main specifications: 15 mm-30 mm
