Refractory products having remarkable resistance to thermal shocks, comprising 60% of the total weight of ceramic fibres, dispersed in 40% of the total weight of cement, obtained by slow heating up to 800 DEG C after the setting and the stripping. A chemical bond is set up in those conditions between the fibre and the calcium aluminate of the cement. Application to the manufacturing of parts remaining in contact with reactive molten metals. |
