Minex Continuous Casting Mould Fluxes are synthetic slags used to cover the liquid steel meniscus in the continuous casting of steel with submerged entry nozzle practice & sold under the Brand name MINTHERM.
Mintherm Casting Powders are scientifically formulated with carefully selected raw materials & have controlled chemical composition , particle size , melting characteristics & melt viscosity to achieve highly satisfactory performance.
Functions of Mintherm Casting Powders :
Mintherm forms three distinct layers when it comes in contact with liquid steel.
 Powder layer : It is the uppermost one providing Thermal insulation preventing premature freezing of steel , skull formation and compensates continuously for the loss of the molten slag. It also protects the meniscus from reoxidation avoiding direct contact with air.
 Viscous layer : absorbs the non metallic inclusions.
 Liquid Layer : its in intimate contact with liquid steel providing necessary lubrication to the solidifying strand by infiltrating between the solidifying shell & copper mold.
Casting powders monitor the heat transfer rate , reduce cooling stresses in the strand and control the meniscus characteristics reducing Oscillating marks and Transverse cracks.
 Homogeneity in Chemical properties
 Low Bulk density , better insulation
 Better spreading & covering
 Less consumption
 Autofeeding possible
 No Dust ,hence environmentally clean
Performance of MINTHERM can be influenced by SEN design & practice and Quality of Steel making.
