Chrome Sand

Refractory Application

Chrome sand is used in the production of chrome magnesite refractory bricks, which are used in the construction of certain furnaces and kilns. Due to its highly corrosion-resistant nature, chrome sand is also used to produce magnesia chrome refractories that are used in non-ferrous metals like copper, lead, and zinc.

In stainless steel production, filler sand made with chrome sand prevents molten steel from settling inside tap holes and solidifying. The chrome sand allows this solution to be effective at high temperatures with long processing times.

  • Stable at high temperatures
  • Thermal-shock resistant
  • Resistant to corrosive slags and gasses
  • High refractoriness/heat resistance

Specifications

  • Cr203 of typically 44%
  • Al2O3 of 15%
  • Chrome content between 15% and 35% Cr203 (Magnesite chrome refractory bricks require 8% to 18% Cr203)
Refractory bricks made with chrome sand are suitable for use in:
  • Open earth furnaces
  • Electric arc furnaces
  • Metallurgy furnaces
  • Cement rotary kilns
  • Glass kilns
  • High-temp industrial furnaces

Data Sheets

Foundry Grade AFS 60-80

Foundry Grade AFS 45-55

Refractory Grade AFS 45-55

African Pegmatites chrome is trivalent chromium (Chrome 3) and not hexavlent (Chrome 6). Hexavelnt chrome is hazerdous and a carcinogen while also being heavily regulated. African Pegmatites chrome is environmentally friendly which is a trivalent chromium.
