Description
技术领域Technical Field
本发明具体涉及冶金领域，具体是一种钒铁合金浇铸锭模及其制备方法。The invention specifically relates to the field of metallurgy, and in particular to a vanadium-iron alloy casting ingot mold and a preparation method thereof.
背景技术Background technique
目前钒铁冶炼浇铸锭模的相关文献资料较少，其主要工艺分为干打结和湿打结操作。干打结工艺操作简单，可用于一次性钒铁冶炼过程的反应容器，在铝热反应过程中，内衬耐材经过高温烧结，形成固态烧结层，但该打结工艺结构疏松，孔隙率高，合金渗透严重。而湿打结工艺由于加入一定量的卤水进行混合捣打，其致密度较干打结高，也可用于短时间高热值的钒铁制备工艺。通过对已公开的相关技术来看，目前浇铸钒铁的锭模打结工艺上改变较小，而更多的关注于结构和功能。专利CN201420410773.2涉及一种浇筑钒铁的锭模，包括上下堆叠设置的上箱和下箱，下箱上部开口，下部封闭，上箱和下箱内的空间为浇注腔，该实用新型的浇注钒铁的锭模，其内部设置有保温层、耐火层和打结层，一方面可以防止锭模外层过度受热，延长锭模使用寿命，另一方面可以对铁水起到保温作用，使铁块慢慢凝固，得到硬度较低易于破碎的铁块。专利201510474486.7公开了一种钒铁合金冶炼用直筒炉炉衬的浇筑方法,将混合均匀的浇注料直接倒入直筒炉炉壳中,搅拌浇注料至炉底浇注料和炉侧浇注料紧实平整,风干后再进行烘烤,冷却后在炉底和炉侧壁对炉衬进行打结处理。该方法能够减少炉底镁砖及镁砂打结用量。专利CN200920177176.9公开了一种电硅热法冶炼FeV50出铁与浇铸装置，其特征在于采用了一个集精炼渣罐、铁水包、锭模为一体的钢制外壳、内衬耐火材料，上大下小，半腰有一个出渣口及出渣溜槽，近似于精渣罐模样的容器，冶炼浇铸后，锭模内的合金液经过一定时间冷却后，脱模精整成产品。该装置有利于减少冶炼过程精炼时间，保护炉体炉衬，但是由于浇铸锭模功能的增加，反而会导致锭模内衬耐材侵蚀的加剧，增加渗合金产生量及合金钒含量。At present, there are few relevant literatures on the casting ingot molds for ferrovanadium smelting, and its main processes are divided into dry knotting and wet knotting operations. The dry knotting process is simple to operate and can be used for the reaction vessel of the one-time ferrovanadium smelting process. During the aluminothermic reaction process, the lining refractory material is sintered at high temperature to form a solid sintered layer. However, the knotting process has a loose structure, high porosity, and severe alloy penetration. The wet knotting process has a higher density than the dry knotting process due to the addition of a certain amount of brine for mixing and ramming, and can also be used for the preparation of ferrovanadium with high calorific value in a short time. According to the relevant technologies that have been disclosed, the current knotting process of the ingot mold for casting ferrovanadium has changed little, and more attention is paid to the structure and function. Patent CN201420410773.2 relates to an ingot mold for casting ferrovanadium, including an upper box and a lower box stacked up and down, the upper part of the lower box is open, and the lower part is closed, and the space inside the upper box and the lower box is a casting cavity. The ingot mold for casting ferrovanadium of the utility model is provided with an insulation layer, a refractory layer and a knotting layer inside, which can prevent the outer layer of the ingot mold from being overheated and extend the service life of the ingot mold on the one hand, and can also play a role in heat preservation of molten iron, so that the iron block slowly solidifies, and obtains an iron block with low hardness and easy to break. Patent 201510474486.7 discloses a casting method for a straight tube furnace lining for ferrovanadium alloy smelting, pouring a uniformly mixed casting material directly into the shell of the straight tube furnace, stirring the casting material until the furnace bottom casting material and the furnace side casting material are compact and flat, air-dried and then baked, and after cooling, the furnace lining is knotted at the furnace bottom and the furnace side wall. This method can reduce the amount of magnesia bricks and magnesia sand knotted at the furnace bottom. Patent CN200920177176.9 discloses an electrosilicon thermal method for smelting FeV50 iron tapping and casting device, which is characterized by a steel shell that integrates a refining slag pot, a ladle, and an ingot mold, and a refractory lining, which is large at the top and small at the bottom, and has a slag outlet and a slag chute in the middle, which is similar to a container in the shape of a refining slag pot. After smelting and casting, the alloy liquid in the ingot mold is cooled for a certain period of time, and then demolded and refined into a product. The device is conducive to reducing the refining time of the smelting process and protecting the furnace lining, but due to the increase in the function of the casting ingot mold, it will lead to the aggravation of the erosion of the refractory material lining of the ingot mold, increase the amount of alloying and the vanadium content of the alloy.
从上述公开的技术来看，目前钒铁合金制备过程主要采用浇铸锭模作为装盛容器和保温容器。由于浇铸锭模打结原材料的限制，浇注冷却过程中不可避免的发生内衬侵蚀以及熔融合金液向锭模内衬渗透。According to the above disclosed technologies, the current vanadium-ferroalloy preparation process mainly uses a casting mold as a container and a heat preservation container. Due to the limitation of the raw material knotting in the casting mold, the lining erosion and the penetration of the molten alloy into the ingot mold lining are inevitable during the pouring and cooling process.
