Metallurgical treatment agents. |
摘要 |
<p>Metallurgical treatment agents for molten ferrous metals e.g. iron and steel and suitable for e.g. desulphurising molten iron and steel comprise particulate magnesium coated with a first coating of a hydrophobic compound and a second coating of a particulate refractory material. The coated magnesium possesses improved flowability and is less prone to premature reaction when subjected to a high temperatures. The hydrophobic compound provides the magnesium with enhanced protection against hydration than may be obtained by a refractory coating alone.</p> |
