Casting installation

Claim 2

A casting installation as defined in claim 1, wherein said linear guiding means comprise guide ledge means provided at said cover member.

Claim 3

A casting installation as defined in claim 1, wherein said linear guiding means are disposed at only one side of said through-flow axis.

Claim 4

A casting installation as defined in claim 1, wherein said positioning element means includes two positioning element members provided at said housing.

Claim 5

A casting installation as defined in claim 1, further including a bottom block sleeve member provided for said container, said bottom block sleeve member including an inlet portion and a bore portion merging directly with said inlet portion, said bore portion diverging in the flow direction of the molten metal material.

Claim 6

A casting installation as defined in claim 6, wherein said bottom block sleeve member is constructed of two portions.

Claim 7

A casting installation as defined in claim 1 further including a bottom block sleeve member and a base plate, said bottom block sleeve member and said base plate engaging in one another.

Claim 8

A casting installation comprising a container for a molten metal, said container including a bottom portion having an opening for the discharge of molten metal material therefrom, control slide means disposed at the region of said bottom opening of said container, said control slide means incorporating a housing and a cover member, a slide member movably mounted between said housing and said cover member, a slide plate supported by said slide member, said slide plate having a through-flow opening, means for guiding said slide member in a substantially linear path including means for guiding said slide member laterally with respect to the axis of material through-flow, said guiding means being provided only at said cover member to both sides of said axis of through-flow, said guide means at one side of said through-flow axis providing a tight fit for linear guiding and at the other side of said through-flow axis a loose fit to accommodate thermal expansion effects, positioning element means provided at said cover member and said housing and engaging one another in order to maintain the path of sliding movement for said slide member which is determined by said linear guiding means in a predetermined plane, a base plate having a through-flow opening and against which is pressed said slide plate, means for providing a clamping force for pressing said slide plate against said base plate, said means providing said clamping force incorporating only two tension screw members, the axes of which screw members are disposed in a plane containing the axis of the through-flow opening of said base plate.
