The invention relates to a molding riser for casting metals, wherein the riser has a metal riser body. The invention also relates to the use of the riser for casting metals into separable casting molds, in particular horizontally separable casting molds.

Riser

This present invention concerns a feeder system for a cast piece with a feeder and/or feeder head and a tubular body, characterized in that the tubular body connects the feeder and/or feeder head directly or indirectly with the cast piece and/or the mold cavity and wherein the tubular body is made of cardboard or steel having a high carbon content.

Feeder with a tubular body

An exothermal feeder mass is described, containing aluminum and magnesium, at least one oxidizing agent, a SiO-containing filler, and an alkali silicate as the binder; it is characterized in that it contains roughly 2.5 to 20% by weight of a reactive aluminum oxide with a specific surface of at least roughly 0.5 m/g and an average particle diameter (d) from roughly 0.5 to 8 microns and is essentially free of fluoride-containing fluxes.
