Abstract
Abstract A vessel for molten metal particularly a tundish for the continuous casting of steel, having a metal shell (1) with a refractory brick layer (2) and a refractory adiabatic - heat resistant - lining (4, 4') on the inner side. In contact with the lining (4, 4') is a refractory layer (3, 3') in loose form which is sintered at a temperature higher than 500°C.
