Your Professional High Alumina Refractory Materials and Refractory Bricks Manufacturer & Supplier !
Although both alumina filler balls and alumina refractory balls use alumina (Al₂O₃) as their main raw material and are spherical in shape, they differ significantly in raw material ratios, core properties, microstructure, and industrial applications. The specific differences are as follows: Different Raw Materials and Ratios Alumina Filler Balls: Primarily composed of high-purity alumina (usually … Read more
Refractory balls are manufactured using industrial alumina and refractory kaolin as primary raw materials, processed through scientific formulation, molding, and high-temperature calcination. The key characteristics of refractory balls include: High mechanical strength and a long service life. Excellent chemical stability; they do not react chemically with the materials they contact. Superior high-temperature resistance. Low thermal … Read more
In iron-making enterprises, the ball-type hot blast furnace is blast furnace blast heating equipment. The core of the technical problem of the spherical hot blast stove is the pebble bed. The pebble bed is formed by the natural accumulation of refractory balls of equal diameter. Generally, it is divided into upper and lower sections according … Read more
