As the temperature increases and the melting of the flux takes place, liquid slag starts dropping from the crucible, which is attached to a load cell. Amazon Renewed Refurbished products with a warranty. Any uses or copies of this document in whole or in part must include the author’s name. Carbon is added to the mould flux to control the melting rate, since this property is related to the availability of liquid slag to fill in the gap between the solidified steel and the cupper wall that assure a perfect lubrication.

In order to assure good performance of mould flux for continuous casting of steel, the chemical composition definition is important to guarantee the properties needs to its perfect behavior in the mould. The quality of steel is directly related to the way the heat transfer occur because the thermal variations produce mechanical loads as well as contact forces which are generated through the rollers and shake of the mold.

A total of 7 cases were tested with significant chemistry variations with different combinations of tundish weight, casting speed and slab width. Go to the privacy disclaimer.
