Carbonaceous refractory paste

摘要

The invention concerns a carbon-containing refractory tap hole clay paste based in particular on anthracite and an organic binder for plugging tap holes in a metallurgic reactor, characterised in that the loss on ignition at 1000 DEG C is at least higher than 80 %, the apparent density of the crude product is between 900 and 1650 kg/m<3> and the apparent density after burning at 800 DEG C is between 600 and 1350 kg/m<3>.
