["主要结构及配置",1,"炉体","井式回火炉炉体由炉壳、炉衬、导风套、加热元件、炉底座组成。"]
[null,2,"炉壳","采用Q235-A钢板经圈制后焊接而成的圆柱形结构，内侧采用型钢加强，底部钢板外侧与底架焊接上部配有炉面板，其结构外形美观，坚固耐用、长期使用不易变形。"]
[null,3,"炉衬","采用超轻质耐火材料，隔热层用全纤维毯状+保温材料。炉底承重采用重质耐火粘土砖和轻质耐火、保温砖间隔砌筑。"]
[null,4,"加热元件","均匀布置在炉衬墙体的内侧，加热元件由0Cr25A15电热合金丝绕制成螺旋状，分布在炉膛内的搁丝砖上，并固定。安装方式确保了加热的均匀性和使用寿命，有极高的可靠性，安装、维修、更换非常方便。"]
[null,5,"炉膛中设计导风桶","导风桶采用 1Cr18Ni9（304）不锈钢制造；有效装料空间不小于工作区尺寸，桶、衬相距今100mm以保护电阻丝和炉衬，导风桶座为“米”字型，以使零件置于有效加热区域内，并利于空气流通、加热均匀。"]
[null,6,"热风循环系统","热风循环系统是为了使炉内温度均匀而设置的。本系统采用热风循环风机，强制炉内热风，顺着导风桶自上而下，使炉内热风形成循环，炉内热风形成循环后，从而使炉内温度的均匀性得到保证，叶轮、风机轴均采用不锈钢制作，叶轮在焊接完成后，经动平衡调试，确保风机旋转时平稳可靠。"]
[null,7,"炉盖内表面","炉盖内表面用 0Cr18Ni9（304）不锈钢板制成。升降采用蜗轮蜗杆升降式，升降平稳、操作简单，当炉盖脱离卡槽后，抓住把手将炉盖向一旁移去即可，当需关闭炉盖时，抓住把手将炉盖与卡槽对齐然后往上轻松按一下电动升降机按钮，升降轴随之下降，直至炉盖与炉体密封。"]
[null,8,"炉盖升降","炉盖升降设置上、下限位，加热回路与风机、炉盖升降实行电气联锁，确保使用安全"]
[null,9,"电器控制部分","仪表控制系统本炉采用固态继电器执行系统及厦门宇电智能仪表进行PID调节控温记录采用厦门宇电的无纸记录仪。温控系统还具有超温声报警功能。"]
[null,10,null,"同时配备有空气开关、接触器和快熔器作二级保护。各组电热元件设置电流表、电压表及电热元件的通断指示，具有安全接地措施，保证使用安全。"]
