内容简介

The bauxite-based self-flow castable and andalusite-based self-flow castable were prepared with special bauxite, andalusite, SiO2 micropowder,α-alumina micropowder and calcium aluminate cement as main raw materials. The specimens were heat treated at 110 ℃ 24 h and 1500 ℃ 3 h,respectively, and their permanent linear change rate,bulk density, modulus of rupture, hot rupture strength,thermal expansion coefficient and thermal shock resistance were tested. The result shows that compared with bauxite-based self-flow castable,andalusite-based self-flow castable has lower modulus of rupture and hot rupture strength, smaller thermal expansion coefficient and better thermal shock resistance. Andalusite-based self-flow castable has been used satisfactorily in permanent lining for 80t tundish of Hyundai Steel.
