Insulating refractory for vacuum casting aluminum alloy casting
The invention relates to an insulating refractory for a vacuum casting aluminum alloy casting. The insulating refractory is characterized by being manufactured from the following components in parts by weight: 20-30 parts of calcination limestone, 4-6 parts of modified corn starch, 4-6 parts of purple sand clay, 0.4-0.6 part of cyclohexanone, 1.5-2.5 parts of gypsum, 4-6 parts of modified white carbon black, 1.5-2.5 parts of magnesium aluminum alloy, 1.5-2.5 parts of an antioxidant, 8-12 parts of clay soil, 4-6 parts of marine mud, 1.5-2.5 parts of quartz, 1.5-2.5 parts of boron nitride, 4-6 parts of calcination kaolin, 4-6 parts of kyanite, and 35-45 parts of deionized water. According to the invention, through the improvement of a traditional formula of fire clay, a layer of a refractory paint with a defined thickness needs to be applied to a pre-embedded copper tube or a stainless steel tube, so that the actions of insulating, preventing softening, and preventing an aluminum liquid from entering a pipeline by the fusing the copper tube can be made.
