| 内容記述 | The presence of hematite phase in CaO-Fe,03-Si02-AI20, quaternary calcium ferrite hinders to clarify the final fractional reduction and the formation of a intermediate mineral phase on initial reduction steps of its calcium ferrite. Therefore, the preperation of hematite free quaternary calcium ferrite was tried, and the final fractional reduction, structure and composition on the initial reduction steps of resultant samples have been investigated, and the chemical molecular formula of a intermediate mineral phasses was calculated reasonably. The main results obtained are as follows: 1) It was recognized that preperation of hematite free quaternary calcium ferrite from the initial mixture corresponding to composition of CaO ·Si02 -2 (Fe089 Alon) ,03 (Si02 =6.74mass%) was possible under the condition of heating temperature 1723K, retention time 1200s and cooling rate 0.083K/s, while it was impossible from initial mixture of CaO·Si02-3 (Feo89Alon),O, (Si02=6.74mass%). 2) In the changes from 5 to 45% of CO concentration in CO-C02 mixed gases, the final fractional reduction were about from 5 to 45% at the temperature 1023K- 1173K. 3) From the reasoning calcuration of the analytic values of reduced samples by EPMA, it was showed that the chemical molecular formula of a intermediate mineral phasses formed on initial reduction steps of quaternary calcium ferrite (Si02 =6.74mass%) were the solid solutions of Si02-3CaO·FeO·7 (Feo82Alo 18 )2 0" Si02-4CaO·FeO·4 (Feo"AloI4),03 and SiO,-CaO·3FeO·(Feo74Alozs),O" and Fe30" FeO, "FeO·CaO" (solid solution involved SiO, & ALO,) and 2CaO·Si02.4) The formation of expected and CaO·FeO·(Fe,Al h )203 in during the initial reduction of samples were not recognized. | |||||||||||||
