METALLURGICAL TREATMENT AGENTS

摘要

Metallurgical treatment agents for molten ferrous metals e.g. iron and steel and suitable for desulphurising molten iron and steel comprise particulate magnesium coated with a first coating of a hydrophobic liquid and a second coating of particulate soda ash. The coated magnesium possesses improved flowability and is less prone to premature reaction when subjected to high temperatures. The soda ash provides enhanced desulphurisation of molten ferrous metals than may be obtained by e.g. refractory coated magnesium.
