Refractory Tundish Powder Iron Steel Smelting Ladle Powder

Insulating covering fluxes for tundish and ladle Refractory Materials Iron and steel smelting

Product introduction

We offer a series of covering flux products including both fine-grained powders and hollow granulated fluxes, so it’s possible for customer to select a suitable material according to operational parameters of each specific application.

Generally for tundish application factors affecting product performance result to be steel grade, exposed steel surface to be covered, casting time, and sequence index. Regarding ladle applications, critical factors are chiefly the amount and the characteristics of the refining slag.

Increasing demand of better quality steel and subsequent use of high performance basic tundish lining material boosted researching and developing of active basic tundish powders assuring high covering, insulating properties and low corrosion activity.

Moreover, effective NMI (non-metallic inclusions) absorption capability is provided by specific viscosity and surface tension of molten slag layer in direct contact with molten steel.

Plant experience in using these active basic tundish powders gave improved steel cleanness.

We offer two types of insulating covering fluxes :

• Rice ash, with high levels of thermal insulation
• Fly ash mixtures, with high levels of thermal insulation and protection against re-oxidation
