For many years , the drying furnace has been adopted with sealed structure and electrical heated , dial instruments are used to control the temperature of the drying furnace and to keep it invariable . parameter setting is inputted by manual method , heating time is completely controlled by operators ’ experiences or their moods , meanwhile , its control function is singular , not only having no automatic heating time and insulating monitoring , having no drying process monitoring , but also having no function of automatic recording and report printing , the workers ’ labor intensity is bigger . thus two abnormal situations are always come forth , one is the insulating performance and intensity of works cannot be guaranteed reliably , it perhaps need to be dried repeatedly , the other is always to extend the drying time in order to ensure the drying quality 多年来干燥炉一直采用闷罐式结构和电加热方式,温度控制采用指针式温度控制仪表来实现炉温的恒定,其参数设定由人工输入,时间控制则完全凭操作者的经验、情绪来掌握,其控制功能单一,没有时间控制、绝缘自动监测功能,也没有干燥过程监视功能,更没有多要素记忆、打印存档功能,工人的劳动强度较大,所以就经常出现两种异常结果:一是工件的绝缘性能和强度得不到可靠保证,需要反复干燥;另一种是为保证干燥质量,往往要延长干燥时间。

The welding technology of francis turbine runners is optimized from the view of subsection welding and local heating by numerical simulation . the result shows that welding residual tensile stress appears in the weld and its area nearby , and peak stress appears in the dangerous area of blades after practising quondam welding technology ; welding residual tensile peak stress in the dangerous area of blades can be decreased by welding both ends earlier and then welding middle section later during subsection welding , and decreasing effect on welding residual stress of the subsection welding is related to the weld length of blade outlets and welding direction of each subsection ; decreasing effect on residual stress of the local heating is direct proportional to heating time , heating temperature , heating area , and inversely proportional to cooling area , and welding residual tensile peak stress in the dangerous area is decreasing trend earlier , and then increasing trend later with heated location increased 本文利用数值模拟手段对转轮的焊接工艺从分段焊和局部加热两个方面进行了优化,结果表明:采用普通工艺焊接时,叶片焊后残余拉应力出现在焊缝及其附近区域,并且在叶片出水边的熔合线附近(危险区域)出现了峰值;在采用优化的分段焊时,先焊两端后焊中间的方法可以降低叶片危险区域的焊接残余拉应力峰值,降低效果与叶片出水边焊段长度、焊缝各段的焊接方向有关;局部加热法降低转轮危险区域残余应力的效果主要与加热时间、加热温度以及加热面积成正比,与冷却面积成反比,并且危险区域的残余应力随加热区域的增大呈先降低后升高的趋势。
