FIELD: technological processes, casting.
SUBSTANCE: invention is related to foundry. Compression box comprises a filling glass with filling window and funnel of rectangular cross section, installed in filling window. Back and front walls of filling glass are parallel to each other and are inclined relative to vertical plane of compression box symmetry. Lower edge of filling window walls is installed above horizontal plane of compression box symmetry. Lower edge of funnel is installed above lower edge of filling window walls. Front walls of funnel and filling window are inclined to the side of melt jet flowing off tray and are installed along tangent to internal surface of filling glass. Upper edge of funnel from the side of front wall is arranged as inclined relative to vertical plane of compression box symmetry.
EFFECT: reduced heating and wear of front wall in filling window and box.
