RESULTS AND DISCUSSION Table 2 presents different castables’ physical properties (permanent linear change - PLC, apparent porosity - AP, apparent density - AD and pore volume attained by SEM images). Both expansion (PLC) and porosity scaled with the MgO grain size increase (AM100 > AM45 > AM13), whereas the density decreased for the expansion free testing condition, after firing at 1500°C for 5 hours. The unfavorable association of such properties (large pores with high porosity) resulted in a deeper slag penetration (expansion free, 18.2 % of infiltration) as showed in Figure 3. This figure also highlights that the penetration index scaled with the expansion (AM13 < AM45 < AM100) for the expansion free firing condition, whereas the results were much closer when a constraining effect was considered. Table 2 - Physical properties (permanent linear expansion, apparent porosity, apparent density, pore volume) for castables with different expansion levels (AM13, AM45 and AM100), fired at 1500°C for 5 hours, in expansion free or under constraint conditions, and their percentage difference when comparing both situations. |

結(jié)果與討論 表2給出了不同澆注料的物理特性(永久線脹縮—PLC,表觀孔隙率(視孔隙率,顯氣孔率)—AP,表觀密度—AD和孔隙體積由SEM圖像獲到)。1500°C燃燒5小時(shí)后,膨脹(PLC)和孔隙度(率)隨氧化鎂粒度(徑)增加(AM100 > AM45 > AM13)而減少,而自由膨脹測試條件下的密度減少。這些屬性(大孔和高孔隙度)的不利關(guān)聯(lián)導(dǎo)致更深的爐渣滲透(自由膨脹,18.2%的滲透(熔滲))如圖3所示。這個(gè)數(shù)字也強(qiáng)調(diào)了滲透(針入度)指數(shù),對自由膨脹的燃燒條件,隨膨脹(AM13 < AM45 < AM100)而減少,而當(dāng)考慮一個(gè)約束效應(yīng)時(shí)其結(jié)果更接近。表2 — 具有不同膨脹水平的澆注料(AM13,AM45和AM100)的物理性質(zhì)(永久的線性膨脹、表觀孔隙率、表觀密度、孔隙體積),在1500°C 燃燒5小時(shí),在自由膨脹或約束條件下,比較兩種情況,他們的百分?jǐn)?shù)差不同。 |
