Fire-resistant thermal insulation part for upper part of inert anode aluminum electrolysis cell
The invention discloses a fire-resistant thermal insulation part for the upper part of an inert anode aluminum electrolysis cell, and belongs to the technical field of aluminum molten salt electrolytic smelting. The fire-resistant heat preservation part is of an integral double-layer structure, namely a lower fire-resistant layer facing the high-temperature electrolyte and an upper heat preservation layer back to the high-temperature electrolyte, and the combination surface of the two layers is of an isosceles trapezoid tooth-shaped structure; the lower refractory layer is made of refractory concrete or fiber reinforced refractory concrete, and the refractory layer is made of aluminate cement concrete with the mark of CA-60 or CA-70; the upper thermal insulation layer is made of aerated porous refractory concrete with a small heat transfer coefficient, the thermal insulation layer is made of CA-50 mark aluminate cement concrete, and the void ratio of the thermal insulation layer is 50-70%; the preparation method comprises the following steps: respectively and independently batching and respectively and independently stirring two kinds of cement concrete, firstly pouring the refractory layer, and then pouring the thermal insulation layer; the fireproof heat preservation part is good in heat insulation and heat preservation effect, light in overall mass and convenient to carry and install.
本发明公开一种用于惰性阳极铝电解槽上部的耐火保温件，属于铝熔盐电解冶炼技术领域；耐火保温件为整体式的双层结构：面向高温电解质的下部耐火层和背向高温电解质的上部保温层，两层结合面为等腰梯形齿状结构；下部耐火层为耐火混凝土或纤维增强耐火混凝土，耐火层使用CA‑60或CA‑70牌号的铝酸盐水泥混凝土；而上部保温层为传热系数小的加气多孔耐火混凝土，保温层使用CA‑50牌号的铝酸盐水泥混凝土，其空隙率为50～70%；其制备方法是两种水泥混凝土分别单独配料和分别单独搅拌，先浇注耐火层，后浇注保温层；本发明的耐火保温件隔热保温效果好、整体质量较轻而便于搬运和安装。
