Open porosity, compressive strength, shearing strength of ET-DL gunningmaterial and its application in testing ground have been investigated. It has been found that both of adhesion and slag-corrosion resistance are good for the gunning material. It was simple and fiexible to repair by machine. The furnace life can be prolonged to more than two-fold after using the gunning material.
