中文摘要 | 一貫作業鋼廠鐵水前處理爐渣含有(CaO、P�烙�ㄐBMgO、S、Fe、Mn等肥料要素, 可做為肥料資材,很適用於臺灣酸化農地。本研究以中鋼公司前處理爐渣做為肥料充填劑, 與氮、磷、鉀化學肥料配製鹼性復合肥料,評估技術可行性,並配製供應高雄區農改場及中 興大學土壤研究中心田間試驗應用。實驗結果顯示:爐渣尾礦經篩分與磁選再處理後之渣粉 可配製成粒狀鹼性復合肥料,品質符合CNS3076標準。粒狀鹼性複肥密度為1.0kg/L,水份約 在 7-9%,水溶液pH值在9.5-10.5間,爐渣肥料不易潮解、結塊或粉化,物理特性良好。試 驗初步結果顯示:爐渣肥料非常適用於花卉。塵用在荔枝果樹上,產量與甜度較高。于研究 確認爐渣肥料技術可行性及適用性。後續研發工作將以試製試用或小量商業化為階段性目標 ,才能有效推動爐渣肥料之落實應用。 |
英文摘要 | An integrated steel plant-generates large quantities of slags in producing hot metal and steel. The slag from hot metal pretreatment system containing many fertilizer nutrients is very suitable for using as ferilizer filler. The important nutrients in the slag include CaO、P�烙�ㄐBMgO、S、Fe and Mn. The study evaluated the technology feasibility of producing basic compound fertilizer that made of the slag and N、P、K chemical fertilizers. The field tests were also proceeded to conform the applications of the slag fertilizer. The experimental results have shown that the basic compound fertilizer can be made by using the fine slag powder, after screening and magnetic separations, as filler. The quality of the slag fertilizer is consistent to the standard of CNS 3076. The granulated slag fertilizer contains 7-9% water at about 1.0kg/1 bulk density and its solution indicates pH value in the range of 9.5-10.5. Preliminary field tests have also shown that the slag fertilizer is very applicable, especially for the flower plantation. A pilot plant for producing the slag fertilizer is now considered for the next study. |
