Description

Riser for nodular iron casting

Technical Field

The utility model relates to the field of risers, in particular to a riser for a nodular iron casting.

Background

The feeder is a supplementary part which is added above or on the side of the casting to avoid the defect of the casting. The function of the riser is that in the casting mould, the cavity of the riser is a cavity for storing liquid metal, the metal is supplied when the casting is formed, the functions of preventing shrinkage cavity, shrinkage porosity, exhausting and slag collection are achieved, and the main function of the riser is feeding.

The dead heads are generally required to be used during production of the ductile iron castings, so that iron juice can be conveniently supplemented into the mold in real time, but the existing dead heads generally directly use the ceramic roller, and the ceramic roller can fall off and scald a user under the action of external force.
