AN IMPROVED SYSTEM / PROCESS FOR COMPARATIVE EVALUATION OF DYNAMIC SLAG CORROSION RESISTANCE OF REFRACTORIES

摘要

An improved system for comparative evaluation of slag corrosion resistance of different quality of refractories with desired metal and slag chemistry and the system comprises induction furnace (6) having inner volume such that 18 to 20 kg of metal can be melted, plurality of sample specimens (1) of different qualities, definite proportions of slag (5) and metal (4) inside the plurality of sample specimens (1), insulations of definite thickness and means (3) adapted for resisting metal-slag attack. The process for comparative evaluation of slag corrosion resistance of different quality refractories with desired metal and slag chemistry comprises lining of the induction furnace with sample specimens, addition of metal/steel to the induction furnace and heating and melting to attain desired temperature, addition of definite amount of slag of definite composition in the furnace, maintaining desired temperature ranging, draining out of metal and slag after completion of desired duration of evaluation, determining thickness of corroded sample specimens and evaluation of corrosion index.[IN227272A1]
