Abstract
The invention belongs to the technical field of refractory materials, and particularly relates to a magnesium aluminate spinel tin refractory castable. The refractory castable is prepared from, by weight, 35-45 parts of aggregate, 35-55 parts of powder and 3-5 parts of auxiliaries. The aggregate comprises magnesium aluminate spinel, periclase, tin oxide hollow spheres and silicon carbide according to the weight ratio of 0.5:0.5:2:2. The powder comprises alpha-Al2O3 powder and carbon nanotubes according to the weight ratio of 5:1. The auxiliaries comprise carboxymethyl cellulose and sodium hexametaphoshpate. The magnesium aluminate spinel tin refractory castable is good in mechanical strength and not likely to break, the material is light, weight is reduced, the material is not prone to fall off, and heat-preservation performance of the material is enhanced due to use of the hollow material.
Description
Technical field
The invention belongs to technical field of refractory materials, particularly relate to magnesium aluminate spinel stannum castable refractory.
Background technology
Vacuum external refining, external refining stove uses light weight castable refractory, to reduce the carbon infiltration steel in refractory material
In water.General low-carbon magnesium carbon light weight castable refractory graphitiferous is below 6%.Reduce content of graphite again and can make low carbon magnesia carbon brick
Coefficient of thermal expansion rises, and is easily generated peeling in using.
Further, since pore size is relatively big in traditional light weight castable refractory, aperture is in grade more, so when this
When material uses in hot environment, due to the aggravation of radiant heat transfer Yu convection heat transfer' heat-transfer by convection, the heat conductivity liter of refractory material can be made
Height, and then reduce the heat insulation and preservation effect of refractory material, increase the loss of heat energy, increase production cost.
Summary of the invention
For above-mentioned technical problem, the present invention provides a kind of magnesium aluminate spinel stannum castable refractory, improves refractory material attached
