一种利用钒钛磁铁矿制备碳化钛的气基竖炉装置
本技术涉及碳化钛制备用设备领域,尤其涉及一种利用钒钛磁铁矿制备碳化钛的气基竖炉装置。
技术介绍
碳化钛(TiC)是一种具有金属光泽的铜灰色结晶体,晶型构造为正方晶系。TiC具有很高的熔点和硬度。TiC具有良好的传热性能和导电性能。TiC粉末由于具有耐高温、耐磨、耐腐蚀、高强度、高硬度、导热导电等性能而被广泛应用于制作陶瓷、切削刀具、耐磨耐火材料、航空和冶金等领域。钒钛磁铁矿可以在气基竖炉中还原制备碳化钛。目前气基竖炉中设有还原室和冷却室,钒钛矿海绵铁还原工序完成之后直接进入冷却室,导致冷却室和还原室中的温度之间存在很大的流通,不利于反应的进行,而且还原室内的温度来源主要为高温还原气体的自身热源,反应过程中热量损失,无法及时补充,顶部的炉顶气直接处理后排放,没有合理利用。
