EBT Olivine Sand

EBT Olivine Sand

Olivine sand is among the most used refractory minerals. Its low free-Silica content and strong resistance to molten metal, along with its refractory properties have made Olivine Sand a popular choice as Eccentric Bottom Taphole (EBT) Filler in Electric Arc Furnaces (EAF), commonly known as EBT Filler.

Some of the applications of olivine sand include:

  • …have made Olivine Sand a popular choice as Eccentric Bottom Taphole (EBT) Filler in Electric Arc Furnaces (EAF), commonly known as EBT Filler.
  • Used in the production of tundish lining refractory castables
  • Used in the production of magnesia-chrome bricks and low-magnesium bricks
  • For lining the back wall in AOD converters

EBT Olivine Sand

The purpose of Olivine Sand as EBT Filler is to ensure a free opening occurs when steel flows freely from the taphole to the ladle once the taphole is opened. Olivine Sand is the most ideal refractory aggregate for EBT Filler applications because molten steel does not have the ability to cause a wetting effect on Olivine sand in the EBT of EAF, and the liquid permeability in the Taphole is reduced.

What is EBT Olivine Sand?

Olivine sand is among the most used refractory minerals. … have made Olivine Sand a popular choice as Eccentric Bottom Taphole (EBT) Filler in Electric Arc Furnaces (EAF), commonly known as EBT Filler. The Olivine sands from Saba Zob Sepahan have high resistance to heat, which increases the opening rate of the furnace to about 100%, playing a significant role in increasing production speed. Olivine sand, with its low free-silica content and strong resistance to molten metal, is widely used in steelmaking to improve furnace performance and increase productivity.

Saba Zob Sepahan is a supplier of Olivine sands for reputable steel companies. Saba Zob Sepahan is a supplier of Olivine sands for reputable steel companies. The Olivine sands from Saba Zob Sepahan have high resistance to heat, which increases the opening rate of the furnace to about 100%, playing a significant role in increasing production speed.
The purpose of Olivine Sand as EBT Filler is to ensure a free opening occurs when steel flows freely from the taphole to the ladle once the taphole is opened. The free opening rate is mainly determined by the quality of the Taphole filler sand. Olivine Sand is the most ideal refractory aggregate for EBT Filler applications because molten steel does not have the ability to cause a wetting effect on Olivine sand in the EBT of EAF, and the liquid permeability in the Taphole is reduced. As a result, EBT Taphole Fillers in EAF-operated steel plants can achieve up to 99% free opening without the requirement of poking or Oxygen lancing.
