Aluminum-magnesium composite ramming material for medium-frequency induction furnaces
The invention relates to an aluminum-magnesium composite ramming material for medium-frequency induction furnaces, which is prepared from the following components in parts by weight: 30-50 parts of glass kiln waste corundum brick, 35-60 parts of cement kiln waste castable, 5-15 parts of magnesium scrap brick and 3-7 parts of high-activity alpha-Al2O3 powder binder. The glass kiln waste corundum brick is composed of the following components in parts by weight: 5-15 parts of powder with the particle size of 6-3mm, 5-15 parts of powder with the particle size of 3-1mm, 5-15 parts of powder with the particle size of 1-0mm and 5-15 parts of 200-mesh fine powder. The cement kiln waste castable is composed of the following components in parts by weight: 10-30 parts of powder with the particle size of 6-3mm, 5-25 parts of powder with the particle size of 3-1mm and 5-25 parts of powder with the particle size of 1-0mm. The particle size of the waste magnesium scrap brick is 325 meshes. By using the glass kiln waste corundum brick, cement kiln waste castable and magnesium scrap brick, the ramming material implements recovery of the waste refractory materials and solves the problems of abundant sedimentation and soil pollution caused by the waste refractory materials. The thermal shock stability and scouring resistance are obviously enhanced, the problems of furnace lining cracking, short service life and the like are reduced, and thus, the ramming material satisfies the smelting demands.
