VAPEX FosFlow nozzle in bottom pour ladle

VAPEX FosFlow nozzles

A solution to rapid changes of nozzle size in bottom pour applications

Product Overview
When using stopper and nozzle technologies for bottom pouring applications it may be desirable to change nozzle diameters between fills of the ladle or even between castings. In normal circumstances this would not be possible as it would require removing and replacing the nozzle and stopper.  
Foseco VAPEX FosFlow nozzle to be used in conjunction with VISO monoblock stopper technology for multi usages.
Key Benefits
  • Quick change of the pouring nozzle
  • Faster ladle set up
  • Suitable for multiple use
  • Less refractory work

Bottom pour ladles: a challenging pour

Bottom pour ladles have a number of advantages over other ladle types, such as lip pour and t-pot ladles. These include shorter casting time and lower maintenance requirements, as well as the ability to gas purge and minimise ingress of slag into the melt stream (these latter two being important for clean casting). However, bottom pour ladles are also prone to turbulence in the pour, which makes the selection of appropriate stoppers and nozzles essential.

The VAPEX FosFlow nozzle system is the latest advance to the Foseco flow control range, and allows foundries to more easily change nozzle diameter – even when the ladle is full. This makes it possible to ensure that optimum flow control is in place for each casting.

Benefits are mostly found in steel foundry applications:

  • The pouring nozzle can be changed quickly 
  • Multiple use of the stopper & nozzle system resulting in labour cost reduction 
  • No cooldown of the ladle resulting in energy savings and increased ladle lining performance
