摘要
设计了三种不同加热方式的高温电阻炉,即外壁加热、内芯加热和双重加热高温炉。介绍了电热元件的材料选取、尺寸确定,保温材料的选用,热电偶的选择与安装。分析了三种高温炉的耗电量、散热量和使用寿命。通过对比,内芯加热高温炉耗电量最低、使用寿命最长,双重加热高温炉升温速度最快,外壁加热高温炉的炉膛有效面积最大。
Three kinds of high temperature resistance furnaces with different heating method are designed, that is, outside - wall heating, inside - wall heating and double heating high temperature furnace. The selection of electric heating dements, the calculation of the size of resistance wires, the determination of heat preservation materials and the installation of thermocouples are presented in detail. The power consumption, heat loss and lifetime of the furnaces are analyzed. By contrast, the power consumption of inside-wall heating furnace is lowest and the lifetime is longest, the heating rate of the double heating furnace is fastest, and the active furnace area of outside- wallheating furnace is largest.
