In order to analyze the expansion behavior of castables, all the specimens were heated up to 1700℃ in RUL (refractoriness under load of 0.2MPa). And the thermal linear expansion rate (at 1600℃) were measured. And the all the specimens were prefired at 1000℃ to obtain sufficient mechanical strength. The HMOR (hot modulus of rupture) was measured at 1400℃ by using specimens with the size of 160mmⅹ40mmⅹ40mm. Table 1. Formulation of the experimental specimen Table 2. Chemical composition of raw materials In order to identify the formationtemperature of spinel and CA6 according to the thermal change, the mineral facies analysis was carried out by using theXRD(X-ray diffraction) at 1100℃,1200℃, 1300℃ and 1400℃ using X’pert PRO(PANalytical, Netherland).And the corrosion resistance was measured by using a rotative corrosion tester, and the ladle slag was used of which the value of CaO/SiO2 was 5.8(CaO/SiO2 = 5.8). RESULTS AND DISCUSSION Fig. 1 represents the RUL curves of four specimens. The specimen A with spinel has not been affected by loadinduced softening, whereas Specimen B, C and D containing magnesia began to be softened at around 1150℃. It is judged that the softening was caused by the influence of microsilica, and the reason why the softening of the three specimens (B, C and D) occurred at the similar temperature was that even small amount of microsilica had a great effect on the RUL1) due to the formation in liquid phase. However, the inclines of RUL become moderate because the expansion was suppressed by the formation in liquid phase as the microsilica contents increased. |
