Alcar International Limited was founded in 1986 with the specific intention of marketing the first “in-line” Tube Changer in the UK and Scandinavia. Tube Changers are used in the continuous casting of steel and as the name implies are devices for changing the submerged entry shroud (SES) commonly known as the “tube”, which is used to protect the metal stream between the tundish and the mould. The “in-line” tube changer was novel because it was the first to change the tube along the axis of the mould without raising the tundish significantly, or even at all, and without interruption to the casting process.
