CERALOY-ALD is aluminum metal/alloy which is used as a de-oxidant in steel casting.

Purpose

Molten steel dissolves oxygen during melting. As the steel cools, the dissolved oxygen combines with carbon in the steel forming carbon monoxide:

[C] + [O] = CO (g)
  • If allowed to occur during solidification this would cause gas porosity in the castings.
  • The amount of dissolved oxygen in the steel depends on the carbon content of the melt, low carbon steel containing higher oxygen.
  • The dissolved oxygen is also affected by the silicon and manganese content of the steel.
  • To avoid gas evolution during solidification, the melt must be deoxidized with an element which combines preferentially with the dissolved oxygen forming a stable oxide.

  • CERALOY-ALD is commonly used in button form for rapid dis-solution.
  • Additions vary from about 0.1% for medium carbon steel to 0.2% for low carbon steel
  • CERALOY-ALD (P)   [Al = 98-99.5%]
