Abstract:
PCT No. PCT/SE94/01177 Sec. 371 Date Jul. 1, 1996 Sec. 102(e) Date Jul. 1, 1996 PCT Filed Dec. 7, 1994 PCT Pub. No. WO95/18869 PCT Pub. Date Jul. 13, 1995A method for continuously providing pretreated molten iron for casting objects which solidify as compacted cast iron, in which inoculating agents are added immediately prior to casting, in exact quantities. In practicing the method, the ability of the fully treated cast iron to crystallize is measured and the result of this measurement is used for feedback control of the supply of inoculating agent, this supply being effected at the last possible stage of the treatment process, so as to optimize the amount of inoculating agent introduced to the system. Since the inoculating a gent will normally include FeSi, it will also fed back and used to increase or reduce the addition of agents for adjusting the carbon and/or silicon contents of the iron as necessary.
