Fig. 5. Results of slag corrosion test for AS (A), ASM (B, C) and AM (D). Table 3. Comparison of operational condition for 2010 vs. 2012 Table 3 presents the differences in operation between 2010 and 2012. As shown in the table, the number heating day was smaller, but the amount of empty ladle time was longer in 2010 in comparison with 2012, which is directly connected with the big changes in temperature of the ladle. Therefore, we have applied the AS castables with excellent thermal stability, which resulted in the good achievement. In order to meet the demand for increase of life time of steel ladle, we have carried out a field test after selecting the ASM (B) as a substitute for AS (A) on the basis of material properties. However, a spalling began to appear from the value of 100heats when the ASM (B) was applied. Consequently, the life time was reduced by 5% due to spalling in comparison with the existing AS (A). In order to analyze the cause of spalling a XRD analysis was carried out by sampling from the hot face and interface parts. |

圖5 AS (A), ASM (B, C) and AM (D)爐渣腐蝕測(cè)試結(jié)果 表3 2010和2012年運(yùn)行條件對(duì)比 表3 展示了2010和2012年運(yùn)轉(zhuǎn)的差異 如表所示,對(duì)比2012年,2010年中加熱天數(shù)少了,但澆桶澆完時(shí)間更長(zhǎng), 這與盛鋼桶溫度的劇變直接相關(guān)。因此,我們使用了熱穩(wěn)定性佳的AS澆注材料,取得了很好的效果。為了滿足鋼水包壽命增加的需求,基于材料特性,進(jìn)行現(xiàn)場(chǎng)測(cè)試時(shí),我們用ASM (B)代替了AS (A),然而從100次加熱開(kāi)始,散裂就開(kāi)始出現(xiàn)了。所以,對(duì)比含有AS(A)的,因出現(xiàn)了散裂其壽命就減少了5%。 為了分析散裂產(chǎn)生原因,我們?cè)诩訜崦婕徒唤缑婕䴓悠飞线M(jìn)行了CRD分析。 |
