Diskus. pp 160-187 ABSTRACT: A method has been developed for speedy analysis of slag for P?05 by means of radioactive P (1). The analysis requires 5-7 min. The method is accurate to within 5-6 percent (rel, ). The consumption of material is 0.04-0.05 millicurie per t 0~ metal. To determine P205, I is introduced into the heat in a mixture with powdered Fe. The mixture is placed in a Cu ampoule and the I with the Fe form ferrophosphorus during the period of heating and fusion. This then undergoes uniform dissemination throughout the volume of the heat. Determination of P205 by Card 1/2 radiometry requires ore tagged sample in which the P205 is 137-58-1-2109 A New Method for Speedy Analysis of Slag for Phosphorus (cont. ) determined chemically. A graph showing determination of PZ05 by radiometry as compared with the data of chemical analysis is presented. The employ- ment of radiometric analysis of slag for P205 makes it possible to take and analyze a large number of samples of,slag in the course of a heat. K. K. 1.

Diskus., pp 160-187 ABSTRACT. The possibility of dephosphorizing during the early part of the fusion process was studied on melts in 350-ton tilting furnaces with 70% phosphorous pig iron ;n their charges. Two types of melt had been prepared: 1) with the upper layer of loose material in the charge consisting of lime and 60-701/o ore; at the &nd of the melting process 10- 14 tons of cinder was given off as slag; 2) with part of the ore in the charge replaced by cinder; the yield of cinder at the end of the melting process decreased to 2-4 tons. It was noted that the cinder, when free of SiO caused the easily fusible com- pound 2 CaO . Fe? L pieces of lime. and was also .03 to form on conducive to the early formation at the time of the cha--ging , of a considerable quantityl of slag '-ontaining 15-207a CaO (and the re- Card I /Z mainder in Fe oxides).' By contrast, any SiO2 contained in an ore 19 58 - 2 - 24 31 Oil the Oxidation of Phosphorus (cont. would, by forming a layer of 3CaO . SiO2, inhibit the slagging of the lime Melts of the first type, from the start of the melting process, boiled vigorously and splas1wd. A slag containint~ I()- 12"/'0 P?05 came out of the furnace by gravity. Melts of' the second type boiled less vigorously, because the Fe 304 of the cinder was harder to reduce, in this connection it was found to be pogsible to soak the slag in the furnace and bring its P205 tip to 12-1516, which resulted in a more thorough dephosphorization at the begin- ning of the melting process and a shortening of the melting and finishing times by 1. 5 hours. It is recommended that 70-80% of the ore of the charge be replaced by readily fusible briquets of cinder and limestone, which would make it possible to recover all of the primary 12-18% P 0- slag. to reduce the melting and fini- shing time, to empty tile fur:n1ace completely after each melt, to increase the durability of the hearths, and to cut down cinder losses during charging.

(K teorii ur5. metallurgicheskikh shlakov PERIODICAL: Izvestiya Akademii Nauk SSSR, Otdeleniye Tekhnicheskikh Nauk, 1957, No.11, pp. 196-198 (USSR) ABSTRACT: As regards the theory of metallurgical slags,three points of view can be distinguished, namely: consideration of the slags as solutions consisting of chemical compounds and of free oxides (Refs 1,2); consideration of the slags as pure ionic solutions ZRefs.3 and 7) and consideration of the slags as solution of chemical compounds and ions into which the free oxides decompose (Refs. 8,9). So far,there is a lot of controversy and no single theory has been accepted and the people concerned with accumulation of experimental data for evolving a theory have no possibility of calculating the equilibrium of metallurgical reactions. Therefore, the authors considered it important to generalise the investigations aimed at elucidation of the physico-chemical nature of metallurgical slags and in this paper an analysis is presented of the e er3jrLental data of one of -the authors and of Shvartsma~jRefs.12,13) relating to the study of the thermodynamic functions of Card 1/2the reaction of desulphuring iron with slags of various On the -theory of metallurgical slags. 24-11-30/31 compositions, synthetic as well as open hearth. Analysis, of the experimental data on the heats of formation 1)03- in various slag melts indicates that in the case of hith P 20 concentrations in the slag and absence of SiO 2 calcium phosphates are formed which dissociate on lowering the P 0 content. Therefore, it can be assumed that the theory ~f metallurgical slag should take into consideration the chemical compounds in the slag as well as the dissocia- tion of these compounds into ions at various concentrations of the components from which these form. Thus, the theory of metallurgical slags should be similar to the theory of concentrated electrolytes. For developing further the theory of slag;- melts it is necessary to determine experimentally the thermodynamic constants of Si, Al, Cr and S, both in diluted and in concentrated slag solutions and also to carry out investigations relating to phosphorus.

On account of difficulties in the experiments,however, the exact values of thermodynamic functions of dephosphorization reactions of iron by slag of different composition are lacking. In the present paper a new investigation Lethod of the distribu- tion equilibrium of phosphorus is applied. Its fundamental idea is an effective saturation of the metal with radioactive phospho- rus introduced into the slag at the very beginning at a constant temperature. This method makes it possible to compute the values both of the thermal effect and ofthe reaction entropy of the de- phosphorization for slag of a certain composition from the tempe- rature dependence of the exponent of the phosphorus distribution , L Assuming any molecular composition of molten slag the equi- y l b rium constant of the reaction P + 5/2 Fe'+ + 4 0 __ *___2PO_3 + 5/2 Fe (1) 4 can be described in a general form T (ZG:L) f (Fr,) (2) where y(T Ci) denotr~s the relation Ka - L Card 1/3 p of the equilibrium concentrations of the reaction participants with On the Thermodynamics of the Dephosphoration of Iron. 20-2-418167 the exception of phosphoru ?,) denotes the relat~i"o~~of s, and f the activity coefficients of all reaction participants.

It is concluded that: 1) At low phosphorus concentrations (below 0.1%P) in the system metal-slag the product of the reaction is phosphate ion POi+,--- the sta- bility of which in the slag is determined by the surrounding cations and the type of quasicrystalline structures Me++ - POI+---. 2) Alkaliearth oxides have a beneficial influence on the dephosphorisation of iron by ferrous slag due to an increase in the heat effect and the entropy of the reaction. For relatively large cations of Sr++ and Ba++ the influence of the entropy factor in comparison with the energy factor is larger than for Ca++ ion.

Between iron and slags of the system CaO-FeO-PiO51 reaction (56) takes place; for slags saturate with CaO the equilibrium constant of the above reaction is expressed by relationship (58) and the free energy change by Card 2/3 equation (61).
