Abstract (en)
[origin: EP0282247A1] A refractory pouring assembly (4, 6, 7, 9; 23, 24, 26, 27, 29; 33, 34, 39) comprises at least one refractory component having a jointing surface adapted to mate with a corresponding surface of another component of the assembly and to which there may be applied primary and secondary, mutually spaced deposits of cement sealant (11, 12; 15, 16; 36, 37), wherein said jointing surface is provided with a recess (5, 8, 13; 25, 28; 35) for receiving a meltable sealing composition which melts under pouring conditions to form a reactive material of initially low viscosity and which reacts under pouring conditions to form a sealing material of high viscosity which in use provides an additional seal between said primary and secondary sealants. The joint-sealing composition comprises a mixture of a low melting (say within 500 DEG C to 650 DEG C) reactive glass e.g. at least 25% borosilicate glass, with a filler, which may be ceramic fibres or a clay.
