Abstract

Abstract: This paper introduces several new test methods for refractory properties, including the square crucible slag resistance test method, induction furnace lining slag resistance test method, and standard pressure-vibration ramming method. Square crucibles offer more cutting options and can be used for quantitative analysis. At most four different materials can be tested in the same crucible at the same time to improve the efficiency. The induction furnace lining slag resistance test method has the advantage of testing multiple samples simultaneously, and the slag can be continuously added for long-term experiments. The standard pressure vibration ramming method ensures the consistency of ramming strength and vibration time during moulding, which ensures that the testing results are reliable and comparable.

Key words: refractories, slag resistance, square crucible, induction furnace, standard pressure
