PRODUCTION OF IRON AND STEEL POWDERS

by Höganäs could readily be comminuted to iron powder. Production of iron powder started on a small scale at Höganäs in Sweden between 1937 and 1939, and regular shipments were made to the USA. These early grades of sponge iron powder were unannealed, containing up to 2% of reducible oxygen (H 2-loss) and up to 0.15% of carbon. Consequently, their

iron processing - The metal Britannica

14-08-2020  Iron powder Iron powders produced by crushing and grinding or by atomizing a stream of molten metal are made into small components by pressing or rolling them into compacts, which are then sintered. The density of the compacts depends on the pressure used, but porous compacts suitable for self-lubricating bearings or filters can be given accurate dimensions by using this technique.

A leader in metal powders born in Sweden Höganäs

Sieurin invents sponge iron method The Höganäs Method is invented by engineer Emil Sieurin. The method means reducing iron ore with the help of coke, lime and clay. After patenting the method, Höganäs starts production in 1911 and in 1912 a plant is built. Later on, Höganäs will start grinding the reduced iron to powder, sponge iron powder.

Traditional food processing can reduce the InsP6 content through loss of water-soluble phytate or through phytase hydrolysis to lower myo-inositol phosphate forms that no longer inhibit iron and zinc absorption. Hence, some processing practices can reduce the need for high-dose iron fortificants in plant-based diets and alleviate safety concerns.
