Casting part comprising an external layer appropriate to form a gas impervious layer, and implementation process |
摘要 |
The invention concerns a component for the pouring of steel that has a body (2) of a refractory material containing carbon. It has a layer (10) that covers the body partially or completely and is capable of forming a surface layer (10a) that is oxidized and densified and is impermeable to gases when it is brought to a temperature above 1000 DEG C. The layer (10) is comprised of a refractory material containing sintering precursors chosen in the group consisting of calcined alumina, reactive calcined alumina, silica fumes and clays. |
