MELT FEEDING FOR STRIP CASTING SYSTEMS

A strip casting system for aluminium and/or aluminium alloys comprising a casting furnace and a revolving chill mould having a casting gap. The revolving chill mould is designed as a roll pair, roller pair, caterpillar pair or belt pair. The strip casting system has an active means for transporting metal melt from the casting furnace to the casting gap and a casting region arranged in front of the casting gap. The casting region is delimited on one side by the revolving chill mould. A melt pool is formed in the casting region, from which metal melt flows or is drawn into the casting gap. The casting furnace is connected to the casting region by a pipe system with means for feeding the metal melt into the casting region, which can feed the metal melt to the casting region below the surface of the melt pool formed in the casting region.

MELTING AND CASTING PROCESS AND COMBINED MELTING AND CASTING FURNACE PLANT
20210362220 · 2021-11-25 ·

A process for melting metal parts and casting the melt in at least one mould and a corresponding combined melting and casting furnace plant are described. In the process, metal parts to be melted are brought into a crucible furnace, and a molten metal is produced therein and made ready for casting. A riser tube integrated in a lid of the crucible furnace is heated in a position remote from the crucible furnace, and the lid with heated riser tube is brought into a position closing the crucible furnace, in which the riser tube projects into the molten metal. A mould is arranged on the lid in a casting position above the riser tube, and the molten metal is introduced into the mould from below by pressurising the melt in the crucible furnace. The combined melting and casting furnace plant is designed to carry out such a process.

Melting kettle
11619449 · 2023-04-04 · ·

Melting kettles for use on vehicles for continuous processing of material for applying lines, stripes, bitumen, crack sealant or the like. The kettles disclosed herein provide heat transfer by use of oil jacketed tanks. A coil may be placed along a lower section for heat transfer through a burner for heating recirculated oil. A coil may be placed in a lower section and an upper section for heating an oil jacket, as well as heat transfer from the entire circumference of a coil placed in the upper section. An upper coil can be fluidly coupled to a lower coil and positioned within the chamber a spaced apart distance from the interior wall of the melter kettle. A mixer system rotates paddles to cause continuous transfer of material around the upper coil. The melter kettle is cylindrical, but can be corrugated to increase heatable surface area.
