我厂热锻模淬火加热用的RJX-100-8箱式电阻炉的炉底结构如图1,它由炉底板、导轨、滚球、托盘组成,它有如下缺点:炉内易损件都是耐热钢件,价格昂贵;操作不方便,每装一炉时都得冒着高温摆好球,往往因炉底板或导轨变形后球不易摆匀,操作更加困难.同时影响锻模质量。我们将炉底改为图2结构,将滚球导轨改为滚轮导轨,其导轨及滚轮见图3、图4。放导轨的耐火水泥枕子(见图5)用耐火 I plant hot forging die quenching with RJX-100-8 box furnace resistance furnace bottom structure shown in Figure 1, which consists of furnace floor, rails, bowls, trays, which has the following disadvantages: Furnace wearing parts are Is a heat-resistant steel, expensive; inconvenient to operate, each with a furnace have braved the temperature swing ball, often due to furnace floor or rail deformation of the ball is not easy to swing, the operation more difficult. At the same time affect the quality of forging. We will be the bottom of the furnace structure as shown in Figure 2, the ball will be changed to the track roller guide rails and rollers see Figure 3, Figure 4. Fire-resistant cement sleepers with guide rails (see Figure 5) are used
