Abstract
This invention relates to a refractory mass of the art known per se for casting, ramming or stamping refractory linings and for metallurgical ladles or tapping channels, based on refractory grog and binder, to which mass there has been added straw-shaped, channel-forming elements, equally distributed throughout the mass, in sufficient amount to make possible rapid-drying.
Claims7
In a refractory mass of the type used for casting, ramming or stamping refractory linings and for metallurgical ladles or tapping channels and composed of 60 to 95 % by weight of refractory grog and 40 to 5 % by weight of binder, the improvement which comprises said mass further containing 0.05 to 0.35 % by weight, based on the solids content of the mass without any additive, of straw-shaped, channel-forming elements equally distributed throughout the mass, whereby rapid drying of the mass is made possible.
