During the assembly process of the roll caster feed tip, the gasket is also permanently fixed to the top or bottom member by any means. The spacers extending through these guides are made of refractory material that is not wetted by molten aluminum alloy. Most preferably, the guide and the spacer are adapted to extend through a channel that diverges from the entrance between the side members and converges to the exit between the top member and the bottom member.
Each roll caster feed tip of the roll casting machine is provided with a device for adjusting the width of the outlet during casting. More specifically, the outlet width is reduced by extending at least one spacer from the inlet to the outlet while continuously feeding molten metal through the inlet. During the width adjustment, the molten metal will not leak from the castertip and will not cause any damage to the casting and rolling equipment.
During the casting of molten metal, the outlet width of the roll casting machine’s feed port can be adjusted. The roll caster feed tip includes a top member, a bottom member, and a pair of fixed side members between the top member and the bottom member to define a molten metal with at least one inlet Metal channel. The method includes slidably extending at least one spacer through the inlet of the feed tip to the outlet and adjacent to the side member.
A method of adjusting the outlet width of the feed end of a roll casting machine, the method includes a top member, a bottom member, a pair of fixed side members between the top member and the bottom member, and a plurality of spacers adapted to slidably extend through the channel. The partition is defined by a plurality of fixed guides extending between the top beam and the bottom beam and the middle part between the side beams, and a movable device for blocking the end of the passage when the spacer does not extend through it. The method includes slidably extending the spacer through the channel to the damming device, forcing the damming device outward, and slidably extending the spacer to the outlet.
