Abstract
The invention concerns a desulphurizing mixture in powder form treating liquid cast iron by injection, consisting (by weight) at more than 50 % of each technical calcium carbide and/or lime, and optionally magnesium up to 40 %, aluminum up to 20 % and other additives such as carbon-containing products and/or coating agents in a total amount of not more than 10 %. The invention is characterised in that it contains sulphur at a content ranging between 1 % and 3.5 %. Said desulphurizing mixture results in improved desulphurizing performance. 7 claims
