摘要: 对比分析传统保温式炉衬和新型强化散热冷凝式炉衬的结构特点,提出采用冷凝式炉衬能够有效解决钛渣熔分电炉炉衬使用寿命的问题。计算了钛渣熔分电炉采用冷凝式炉衬炉墙的温度梯度以及热流密度,以25 500 k VA钛渣熔分电炉为例,相比保温式炉衬的维修费及停炉损失,冷凝式炉衬增加的2.4%散热损失可以接受。给出一种冷凝渣壳层最小厚度的确定方法,计算得出镁砖材质冷凝式炉衬厚度为600 mm时,钛渣渣壳层厚度最小为109 mm。Abstract: Characteristics of the traditional heat preservation lining and the novel condensing lining were analyzed,and application of the condensing lining was put forward to prolong the service life of lining in the melting electric arc furnace for titanium slag. Wall temperature gradient and heat flux were calculated in the melting electric arc furnace with condensing lining. Taking 25 500 k VA melting electric arc furnace as an example,the increased 2.4% of heat loss with condensation lining is acceptable,considering the much higher maintenance cost and furnace shutdown loss with heat preservation lining. This paper can provide a method of determining the minimum thickness of the slag shell in titanium slag melting electric arc furnace with condensing lining. When the thickness of condensing lining composed of magnesite is 600 mm,the minimum thickness of titanium slag shell is 109 mm.
