Abstract
The invention discloses an integrally cast calcium carbide furnace door which is prepared from the following raw materials in parts by weight: 40-80 parts of slaty corundum of which the granularity is 8-0mm, 10-25 parts of slaty corundum of which the granularity is 120-180 meshes, 5-15 parts of silicon carbide of which the granularity is 120-200 meshes, 5-10 parts of alpha-Al2O3 micropowder of which the granularity is lower than 5 mu m, 5-8 parts of pure calcium sodium aluminate cement and 4-7 parts of water. Slaty corundum and other refractory materials are integrally cast into the calcium carbide furnace door, and thus, the calcium carbide furnace door can resist the high temperature of higher than 1800 DEG C, does not have weakness, has high thermal stability, and can avoid the phenomena of electric leakage and stony edema.
