Electric furnace bottom ramming material
The invention discloses an electric furnace bottom ramming material, and relates to the technical field of refractory materials. The invention relates to an electric furnace bottom ramming material which is prepared from the following raw materials in parts by weight: 60 parts of magnesium oxide; 30 parts of calcium oxide; 8 parts of iron oxide; 6 parts of recovered alumina-magnesia carbon brick particles; 2 parts of aluminum oxide; 2 parts of silicon dioxide; and 4-5 parts of a binding agent. The granularity of the magnesium oxide is 0.1 to 2mm; the granularity of the calcium oxide is 1-3mm; the granularity of the iron oxide is 2-5mm; the particle size of the recovered alumina-magnesia carbon brick particles is 2-5mm; the particle size of the aluminum oxide is 5-10 mm; and the particle size of the silicon dioxide is 1-3mm. By adding the waste alumina-magnesia carbon brick particles into the raw materials, on one hand, when the working temperature of the ramming material layer rises, the ramming material layer reaches the heat conductivity coefficient matched with the carbon bricks and a cooling wall, so that normal heat conduction is guaranteed, the overall construction structure is not damaged, and the requirement for prolonging the service life of the blast furnace is met; and on the other hand, the waste alumina-magnesia carbon bricks are utilized, so that the waste of resources and the environmental pollution are reduced.
本发明公开了一种电炉炉底捣打料，涉及耐火材料技术领域。一种电炉炉底捣打料，包括由以下重量份的原料制成：氧化镁：60；氧化钙：30；氧化铁：8；回收铝镁碳砖颗粒：6；氧化铝：2；二氧化硅：2；结合剂：4‑5。所述氧化镁的粒度为：0.1‑2mm；氧化钙的粒度为：1‑3mm；氧化铁的粒度为：2‑5mm；回收铝镁碳砖颗粒的粒度为：2‑5mm；氧化铝的粒度为：5‑10mm；二氧化硅的粒度为：1‑3mm。本发明通过在原料中添加废弃铝镁碳砖颗粒，一方面使得捣打料层在工作温度升高时，达到与炭砖、冷却壁相匹配的导热系数，以保证热传导的通常，不损坏其整体的施工结构，从而达到提高高炉寿命的要求，另一方面对废弃的铝镁碳砖加以利用，减少了资源的浪费以及环境污染。
