Improvement of the corrosion resistance of alumina–chromia ceramic materials in molten slag

摘要: Abstract In the previous study, we found out that corrosion of ceramic materials in molten slag depended strongly on viscosity and basicity gap between ceramics slag. this propose experimental equation to predict rate a material as functions basis tests. Cr2O3–Al2O3 were used for tests SiO2–CaO–B2O3 based model The obtained is follows: logΔ D=0.18 ∗ log Δ B−0.55 η+C where, ΔD depth (μm), ΔB specimen, η (Poise). C constant depends conditions corrosion. value 2.7 testing temperature 1573 K, holding time 3600 s rotating speed specimen 5.2 cm s−1 within test.
