What is the bulk density of the castable for the tapping

The bulk density of the castable in the iron ditch is an important index to measure whether the castable in the iron ditch is dense or not It is the ratio of the dry mass of the castable to its total volume that is the mass per unit volume of the castable expressed in g / cm3 or kg / M3
