PROCESS AND PRACTICE OF APPLICATION OF HOT IRON OF FIRST SMELTING, OF MIXTURES WITH METALLOPHOSPHATOCEMENTS IN MACHINE-BUILDING FOUNDRY

Abstract

There the theoretical foundations, the production process of cast machine-building articles with the application of hot conversion pig iron in the metal charge, with the application of rapid-solidifying metallophosphatocement low-toxic mixtures with the reversible solidification character in the lining-formation processes have been developed. The routes of application of hot pig iron in the metal charge, which decrease the melting loss and the dust-making, have been offered. The interconnection between the hereditary properties of iron and the optimization of casting process has been ascertained. The known metallophosphatocement mixtures have been improved, the new ones have been developed and have been introduced. The opportunity to use the exhausted mixtures as well as to regenerate them with the magnetic fields and with the pneumoclassifiers has been determined. The request, the specifications for the building of shop working by the hot conversion pig iron have been formed. The firebrick in the linings has been changedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
