Product Description

High density refractory alumina ball with competitive price

The alumina ball is also called the high aluminum accumulation of heat ball.High alumina refractory ball is based on bauxite as the mainly raw refractory material.Adding powder and additives and anchoring agent.After proportioning, molding and high sintering to make it.The production engineering of high alumina refractory ball is similar to that of high alumina refractory brick.It should be based on the properties of raw materials,high alumina refractory ball requires production conditions and other factors to determine.

The function of high aluminum refractory ball:it mainly stacked in industrial kilns, which can achieve the effect of accumulation of heat.
The application of high aluminum refractory ball : it can be used in the blast furnace ironmaking of Cowper blast air heater, high and low temperature conversion furnace in chemical fertilizer plant, conversion furnace, hydrogenation converter, desulphurization trough and methane furnace.Reformer, hydrogenated converter and desulphurizing tank.,Methane furnace.
