A New Test Method for Hot Abrasion Resistance on Refractories

摘要

Test methods for hot abrasion resistance of refractories in China and overseas were briefly introduced.A new test method for hot abrasion resistance was researched.The new method inherits test principle of cold abrasion resistance in Chinese standard totally,adopts compressed air pre-heating and electricity heating samples,and is featured with complete structure,good controllability,simple operation,and small size.The characteristics and operating procedure of HAT-14A tester were introduced.The hot abrasion resistance of various refractories at different temperatures was tested.
