| abstract |
The invention relates to a self-hardening refractory composition for use as a working lining for metallurgical vessels. The invention can be used to minimise the full lining cycle time for metallurgical vessels by dispensing with heating steps and reducing the lining application time, the time required to form or cure the composition used for same and finally the mould removal time. Using different types and different quantities of liquid binders and additives, the invention modulates the forming or hardening reaction speed of the self-hardening composition. The properties of the resulting working lining, such as the mechanical strength, density and thermal conductivity thereof, can also be altered according to the type of material comprising the self-hardening composition and the type of application used. |
