Customer in Ecuador ordered 12 tons refractory ceramic balls and 48 tons ceramic fiber blankets
In Oct. 48 tons ceramic fiber blankets and 12 tons refractory ceramic balls are packed for delivering to customer in Ecuador.
The difference between the content of high aluminum refractory ceramic balls according to its triple oxidation two aluminum (AL203) content, 48%, 55%, 60%, 65%, 73%, 75%content is often used, and of course, there is still higher The above content is attributed to Corundum Bricks.
According to the content of the content of 55, it is called a clay refractory ball. It is a neutral refractory material. It is fired from the material made of aluminum aluminum or other materials with high aluminum content. It has high thermal stability and refractory temperature of about 1700 ° C. It is used for the lining of glass furnace, cement rotation kiln, and steel making electric furnace. Of course, there are high -aluminum clay resistance refractory balls with high lotus, low creep, and low pores.
The normal temperature resistance of the refractory ball is an important technical indicator of the material. Although the static load that the fire ball to resistance ball in general thermal workers is not large, it generally does not exceed 0.1 ~ 0.2MPa. In addition to improper transportation and masonry, the material is damaged and squeezed by the material, and it is rarely damaged due to the low normal temperature resistance of the material.
The current standards are stipulated that the normal temperature resistance of the fire ball to resistance is not less than 15000N/ball, mainly because the normal temperature resistance of the refractory ball is a parameter of its organizational structure. The formation of the refractory ball structure is restricted by various process factors during the preparation of materials, such as the characteristics of the raw materials and ingredients, particle size and grade matching, and the combination of particles, forming methods and sintering status, etc., all of which are micro -micro -micro -micro -micro -micro -micro The structure has an important impact.
Therefore, normal temperature resistance strength is a reliable method for testing the current process. In addition, the normal temperature resistance of the material can indirectly evaluate the quality of other mechanical properties, and the good abrasion resistance and impact resistance are corresponding to its high normal temperature resistance strength.
The refractory ceramic ball is based on industrial alumina and fire -resistant kaolin as the main raw materials. It is made of scientific formula, forming and high temperature. The refractory porcelain balls are divided into ordinary refractory balls and high aluminum fireballs. Ordinary refractory ceramic balls are suitable for converters and converters in the sulfuric acid and fertilizer industries. High aluminum refractory balls are suitable for hot air furnaces, heating change furnaces in urea, steel and other industries.
