Pouring crane – with automatic bottom pouring, movable and positioning over mould lines

For automatic pouring of large moulds, standing in pouring lines, SUZHU did develop and start-up a special auto pouring using bottom ladles with stopper rods. At Guangdong FUWA Engineering Machinery Co., Ltd. the automatic bottom ladle pouring works with flasks 2500 x 900 mm by productivity 42 complete moulds per hour. The system is used for pouring of steel and ductile iron with bottom pouring ladle 10 tons.

By overhead crane, the bottom-pour ladle is set into the movable pouring crane. The pouring crane clamps the stopper rod of ladle and moves the stopper hydraulically accordingly to the controlled pouring process, opening or closing the pouring spot on bottom of the ladle. The ladle supports on weight cells; the remaining metal weight in the ladle is calculated.

Data transfer to pouring crane

The pouring crane is executed with PLC control and network connection to the moulding plant and gets transferred from moulding plant information data for current and next to be poured mould:

  • the location of sprue Cup
  • pouring weight (target) – pouring temperature (target)

Automatic positioning

The pouring crane is movable along the moulds in one or two pouring lines and locates its position exactly over the moulds.

Automatic pouring process

The stopper rod of the pouring ladle is automatically opened after positioning of the ladle over the next poured mould.

Cameras control the complete pouring process, by image processing analysing of the level of metal in the pouring sprue.

Infrared measurement controls the pouring temperature.

Data transfer from pouring crane

The process control system transfers pouring data information to the foundries data network or to the moulding plant about:

  • ladle number
  • pouring weight (really)
  • pouring temperature (really)
  • weight of remaining metal in ladle.
