ANORDNING FOR RENGORING AV STALVERKSKOKILLER MED EN HOJ- OCH SENKBAR SAMT ROTERBAR STAV FOR UTBLASNING AV ETT BLESTRINGSMEDEL MOT KOKILLENS INNERVEGG

摘要

A device for cleaning steel works molds with at least two chambers, into which the molds that are to be cleaned are inserted. The chambers are downwardly open and can be closed at the top by a lid. They are arranged side by side on a mold grate above the foundation pit and in the foundation pit a lance for blasting abrasives onto the inner walls of the mold is arranged on a substantially horizontal lance carrier, which is rotatable about a vertical axis, so that the lance can be brought into blasting position below each chamber in turn.
