【摘要】：采用熱態(tài)改質(zhì)方法可直接將冶金熔渣制備成高附加值材料,從而實(shí)現(xiàn)熔渣的"熱""渣"雙利用,因此這一方法在熔渣資源化利用領(lǐng)域中已成為研究熱點(diǎn).本文選取熔融鋼渣和河沙分別為典型熔渣和改質(zhì)劑,模擬計(jì)算分析在1600℃熔渣內(nèi)摻入改質(zhì)劑的過程中改質(zhì)劑摻量對(duì)改質(zhì)熔渣顯熱的影響,并對(duì)研究結(jié)果進(jìn)行工業(yè)試驗(yàn)驗(yàn)證.研究表明:隨著改質(zhì)劑摻入,改質(zhì)熔渣顯熱呈現(xiàn)先增加后減小的趨勢(shì);隨改質(zhì)劑摻量由5%增加到11%時(shí)改質(zhì)熔渣顯熱反而增加,當(dāng)改質(zhì)劑摻量為11%時(shí)改質(zhì)熔渣顯熱達(dá)到最大.從熔渣顯熱利用和改質(zhì)效果綜合考慮,改質(zhì)劑摻量的理論最佳區(qū)間為11%~19%.現(xiàn)場(chǎng)試驗(yàn)表明,摻入12%左右的河沙后,改質(zhì)熔渣流動(dòng)性好,冷卻渣安定性等性能改善顯著.
[Abstract]:The metallurgical slag can be directly prepared into a high value-added material by means of hot state modification, thus realizing the double utilization of "hot" slag "of molten slag. Therefore, this method has become a research hotspot in the field of slag resource utilization. In this paper, molten steel slag and river sand are selected as typical slag and modifier, respectively, and the effect of the amount of modifier on the sensible heat of modified slag during the process of adding modifier into slag at 1600 鈩，
