Abstract

The invention relates to free-flowing castable and castings produced therefrom. Refractory nonbasic and basic castables have been known for a long time. The traditional refractory castables have thixotropic properties and must be lined using vibration technology. In the past, free-flowing castables were solely based on alumina raw materials. Attempts to produce an aqueous, highly concentrated basic suspension which would form the basis of free-flowing castables failed to meet the requirements in terms of rheological properties and a low degree of hydration of the MgO-based materials. It is the aim of the invention to provide the above-mentioned castable for the monolithic lining or repair of high-temperature equipment and for the production of refractory castings. This is achieved by providing a fine-grained and a mixed fine and coarse-grained alternative. For the fine-grained alternative a refractory, dilatancy-promoting material on MgO
basis with a grain size between 0.1 and 45 µm and at least one dilatancy-promoting dispersing and wetting agent is employed with the addition of predetermined amounts of mixing water. For the mixed fine and coarse-grained alternative, again on MgO basis, in addition a refractory material with a grain size of up to 15 mm as well as binding agents are employed. In both alternatives, refractory and other additives improving the quality of the final products can also be employed.
