Refractory jointing materials, in particular for discharge closures on metallurgical vessels

摘要

Refractory jointing materials (a, b, c), in particular for discharge closures on metallurgical vessels, are, as shaped and unshaped products, provided with a component of at least 5% of vermiculite. In this respect, the swelling power of the vermiculite enables the optimal setting of any joint pressure required without the application of external force. <IMAGE>
