Test methods of corrosion in melts for refractories

Wearing tests for slag/metal interface and metal zone testing methods have been analyzed and classified with respect to the characteristics and actual use of these methods. Description of the fundamentals of corrosion behavior. But no widely accepted theory in relation to slag corrosion testing methods has been established. The choice of an appropriate slag corrosion test method should be made according to conditions in each actual furnace. We have made an attempt to unificate the different testing conditions to improve the comparability of the different methods e.g. Button Test, Crucible Test Slag Drip Test Dip Test, Rotary Furnace Test and Induction Furnace Test Scope of the tests.
