The invention belongs to the technical field of kiln castables, and discloses a castable for an electric furnace cover, which comprises the following components: a waste sliding plate material, flintclay, silica micro-powder, aluminum micro-powder, silicon carbide and stainless steel fibers. The waste sliding plate material, the flint clay, the silicon micro-powder, the aluminum micro-powder, thesilicon carbide and the stainless steel fibers are sequentially as follows in percentage by weight: 50%-70% of the waste sliding plate material, 20%-30% of the flint clay, 2%-5% of the silicon micro-powder, 5%-8% of the aluminum micro-powder, 2%-5% of the silicon carbide and 1%-2% of the stainless steel fibers. The invention further discloses a preparation method of the castable for the electricfurnace cover. The waste sliding plate is adopted as a main raw material, the cost of the electric furnace cover made of the castable is reduced compared with that of an existing electric furnace cover, the electric furnace cover has good performance in the aspects of compressive strength, breaking strength, refractoriness and the like, and good environmental protection benefits are achieved; andthe flint clay is added, so that the prepared electric furnace cover has good thermal shock stability under the condition of rapid cooling and rapid heating.
本发明属于窑炉浇筑料技术领域,公开了一种电炉炉盖用浇注料,包括以下组分:废滑板料、焦宝石、硅微粉、铝微粉、碳化硅和不锈钢纤维;其中,所述废滑板料、焦宝石、硅微粉、铝微粉、碳化硅和不锈钢纤维按重量百分比计依次为:废滑板料50%~70%、焦宝石20%~30%、硅微粉2%~5%、铝微粉5%~8%、碳化硅2%~5%,不锈钢纤维1%~2%。本发明还公开了一种电炉炉盖用浇注料的制备方法。本发明采用废滑板为主要原料,通过该浇筑料制成的电炉炉盖不仅相对于现有的电炉炉盖成本降低,也在耐压强度、抗折强度和耐火度等方面具有不错的表现,起到了良好的环保效益;焦宝石的添加使得制成的电炉炉盖在急冷急热条件下热震稳定性好。
