Abstract
1418049 Production of iron-containing shaped articles GUTEHOFFNUNGSHUTTE STERKRADE AG 12 June 1973 [6 July 1972] 27812/73 Heading C1A [Also in Division B5] A process for the production and hardening of cold-set shaped articles containing iron compounds comprises shaping a mixture of foundry return material comprising dust from a dust removal plant of an oxygen-blowing converter, and optionally foundry return scraps of pelleting fineness, and a hydraulic binding agent of pelleting fineness into pellets and subsequently hardening the pellets while they are kept in motion relative to each other from their formation at least until the pellets no longer agglomerate when not in motion. The preferred method uses a plant having a pelleting plate for feeding pellets to a bunker, the bunker being arranged to discharge at a discharge rate whereby the bunker remains full and one or more supply pipes, which end in the bunker, for receiving a pile of pellets to form a column, the column of the feed pipes being such that the pellets remain in the feed pipes for 2-5 hours. Hardening of the pellets can be accelerated by blowing in hot air or steam. The pellets can be further hardened under water, the water for hardening can be flowed in a cycle and/or heated to a temperature of from 40-70‹ C.
