A casting powder useful in continuous casting of steel contains inorganic oxidic material meltable at the steel casting temperature and active carbon having a specific surface area according to BET of from 800 to 1200 square meters per gram.

Casting powder for the continuous casting of steel and a process for the

The instant invention is directed to a method of producing a reaction mixture for forming solid or cellular materials from flowable reactants and, optionally, fillers, comprising premixing the components and, optionally, fillers in a first mixing zone and after-mixing in a second mixing zone, the improvement wherein said after-mixing is carried out in a slit-like annular zone which extends radially from the center, the surface boundaries of said annular zone are not parallel and one of said surface boundaries is rotated while the opposite facing surface boundary remains stationary. The instant invention is also directed to an apparatus for producing a reaction mixture for forming solid or cellular materials from flowable reactants and, optionally, fillers, comprising:
