The invention relates to a sponge hafnium and zirconium distillation resistance heating furnace, which comprises a shell, a flange is connected under the shell, a fire-resistant fiber module is arranged in the shell, a resistance heating band is arranged in the fire-resistant fiber module, the flange is composed of a main flange and an auxiliary flange, and is connected concentrically. The shell is a cylinder, which is vertically connected with the flange, and the outer edge of the main flange is provided with a cooling water jacket The sealing iron is surrounded by the sealing iron of the main flange and the cooling water jacket to form a cooling water jacket, and a high temperature resistant coating layer is applied between the refractory fiber module and the resistance heating belt. The advantages are simple structure and low cost. The flange is composed of the main flange and the attached flange, and the heat exchange between the cooling water inside and outside the furnace is greatly reduced; the thickness of the refractory fiber module is uniform, and the high temperature resistant coating layer is painted at the same time, the heat preservation and insulation effect is greatly enhanced, the power supply time is shortened, and the use safety is guaranteed. And the shell is changed from two parts of welding connection to one part, which increases the air tightness of the shell and makes the maintenance more convenient.

海绵铪、锆蒸馏电阻加热炉
本技术涉及一种海绵铪、锆蒸馏电阻加热炉,特别涉及一种节能的下冷式双锭蒸馏海绵铪、锆电阻加热炉。
技术介绍
海绵铪、锆生产过程中,在海绵铪、锆蒸馏电阻加热炉的高温和真空条件下,利用铪、锆与MgCl2、Mg的蒸汽压性质的差异,可实现铪、锆与MgCl2、Mg的有效分离。如图1所示,现有海绵铪、锆蒸馏电阻加热炉,包括由锥形部分与圆柱部分焊接而成的壳体1.1,在壳体下方设有法兰,在法兰1.2上表面设有冷却水套密封铁1.3,由法兰1.2和冷却水套密封铁1.3围成冷却水套1.4,在壳体1.1内部设有耐火纤维模块1.5,在耐火纤维模块1.5内设有电阻加热带1.6。这种结构的海绵铪、锆蒸馏电阻加热炉,其锥形部分耐火纤维模块1.5厚度不均,不利于保温,且停止供热时,耐火纤维模块1.5有可能因为骤冷而粉碎;冷却水套1.4内冷却水通过法兰1.2与炉内进行热交换,也会导致热量散逸。因此,现有的海绵铪、锆蒸馏电阻加热炉难以满足节能要求。
