Method for preventing ferrovanadium alloy from being bonded to electric arc furnace lining in high-temperature smelting
The invention relates to the technical field of ferrovanadium alloy production, and particularly discloses a method for preventing ferrovanadium alloy from adhering to an electric arc furnace lining in high-temperature smelting, which comprises the following steps: uniformly mixing fused magnesia, dolomite refractory material, light calcined magnesia powder and magnesium chloride solution to obtain a knotting refractory material; the bottom and the side wall of the electric arc furnace are filled with the knotting refractory material, and primary knotting is conducted; light calcined magnesia powder is spread on the bottom and the side wall of the electric arc furnace after primary knotting, secondary knotting is carried out, then natural curing and baking curing are carried out, and the electric arc furnace after furnace body curing can be used for smelting ferrovanadium alloy. According to the method, the electric arc furnace is knotted by selecting the knotting refractory material with specific composition, and a stable high-strength compact layer is formed in the electric arc furnace by controlling a specific knotting process and curing conditions, so that the problem that the alloy melt is bonded with the lining of the electric arc furnace is effectively avoided, the yield of the alloy is increased, the smelting cost is reduced, and the production efficiency is improved. High popularization and application values are realized.
本发明涉及钒铁合金生产技术领域，具体公开一种防止钒铁合金在高温冶炼中粘结电弧炉炉衬的方法，步骤如下将电熔镁砂、白云石质耐火材料、轻烧氧化镁粉和氯化镁溶液混合均匀，得打结耐材；将所述打结耐材填充至电弧炉的底部和侧壁，进行一次打结；向一次打结后的电弧炉的底部和侧壁铺撒轻烧氧化镁粉，进行二次打结，然后进行自然养生和烘烤养生，炉体养生结束后的电弧炉即可用于钒铁合金冶炼。本发明通过选择特定组成的打结耐材对电弧炉进行打结，并通过控制特定的打结工艺和养生条件，在电弧炉内部形成稳定的高强度致密层，有效避免了合金熔液与电弧炉内衬粘结的问题，有利于提高合金的收得率，降低冶炼成本，具有较高的推广应用价值。
