Product Description

Shenghe Refractories has engineered the Delta castable for EAF Delta to achieve highest refractoriness in a wide range of operating conditions including thermal shock, steel slag washing and gas attack, high-temperature radiation and the air abrasion caused by dust flow. Delta Castable is produced by ultrafine powder technology, high-quality binders and additives, and the precise distribution of the grain size to meet with different customers’ needs. 

Features

  • Good thermal shock resistance
  • Good volume stability and long service life
  • Excellent in erosion and corrosion resistance
  • High temperature impact from electrodes
  • High temperature radiation during melting and treatment of steel
  • Suitable for normal EAF, Ultra High Power EAF, Refining Furnace and VD Furnace Roof
  • Pre-cast Delta roof can be tailor made accordingly to customer specifications.
