Basic Oxygen Furnace (BOF)

Thermal Insulation and prevention of re-oxidation:

• To avoid heat loss that could cause premature solidification of liquid steel in the meniscus.
• It also creates a barrier to avoid re-oxidation by contact with air and entrapment of other gases, such as nitrogen

Inclusions entrapment:

• Casting Fluxes are designed to absorb any inclusions floating to the top surface.

Lubrication between steel shell and the mould:

• Good lubrication is a very important function of Casting Fluxes. The lubrication capacity is related to the viscosity and solidification temperature.

Heat transfer control:

• Horizontal heat transfer has a significant effect on the surface quality of the product. The vertical heat transfer helps overcome defects like pinholes and deep oscillation marks.

Full Range of Granules & Powder for Closed and Open steel casting

• Carbon & Alloy Steel Grades (Slab, Bloom, Billet & Beam Blank)
• Thin Slab Casting
• IF Grades, Silicon Grades
• Stainless Steel
• Bottom Pouring fluxes
• Exothermic Starting Powder

• Good flowability with minimum dusting when applied over the molten steel in Tundish.
• No crust formation on the molten steel surface, provided an adequate depth of insulating cover is maintained.
• Good ability to absorb non-metallic alumina etc inclusions floating out of the steel.
• Compatibility with basic Tundish lining systems and with refractory Tundish components such as Monobox, Weirs, Dams and Shrouds.
• Prevention of re-oxidation and N₂ pick – up by providing a chemical barrier between the steel and the atmosphere.
• Adequate thermal insulation in most applications.
