The invention discloses a nanometer material contained
ladle bottom
argon blowing permeable
brick and a preparation process thereof. The permeable
brick comprises components of high-purity
corundum,
spinel, alpha-Al2O3 micro powders, nano
calcium carbonate, Si powders, binding agents and antiknock agents. The preparation process of the nanometer material contained
ladle bottom
argon blowing permeable
brick includes the following steps of dosing,
fine powder premixing, stirring, vibration forming, curing with molds, demolding,
drying and baking. According to the nanometer material contained
ladle bottom
argon blowing permeable brick and the preparation process thereof, Cr2O3 is not used, and during usage, new pollutants are not generated, so that
pollution treatment costs are reduced, and high environmental benefits are achieved; micropores are evenly distributed in the brick, so that cracks are effectively prevented from continuing spreading during usage, the
toughness of the permeable brick is improved, the spalling is reduced, the service life of the permeable brick is prolonged, the permeable brick is basically free from bonding
slag after usage, cleaning during usage is reduced, and production costs of iron and steel enterprises are reduced.
