博山锻压厂95连杆辊锻自动线是我国自行设计的第一条锻压自动线。81年11月已由农机部鉴定验收。该自动线的坯料加热工序采用可控硅中频感应加热。感应加热由于输入功率稳定,出料节拍固定,则加热的稳定性好,温度均一,保证了加热质量。加热装置自77年来安装投产后,运行情况良好,稳定可靠,没有进行过大修,没有薄弱的贵重易损件。尽管一次投资大些,但总的来说采用(感应)电加热方式除上述的优点外,在节约一次能源消耗方面是非常显著的。从企业自付燃料费用来看,电加热的燃料费也不比其它加热方式的燃料费用高多少,(以下有详细的数字对比)
Boshan Forging Factory 95 roller automatic forging line is China’s first self-designed forging automatic line. November 81 has been identified by the Ministry of Agricultural acceptance. The automatic line billet heating process using SCR induction heating. Induction heating due to stable input power, the material beats fixed, the heating stability, temperature uniformity, to ensure the quality of heating. After 77 years of installation and commissioning of the heating device, the operation is in good condition, stable and reliable, no overhaul, no weak and expensive wearing parts. In spite of the large investment at one time, the overall use of (inductive) electric heating is remarkably significant in terms of saving primary energy, in addition to the above advantages. From the point of view of enterprises’ own fuel costs, the fuel cost of electric heating is not much higher than the fuel cost of other heating methods (the detailed numerical comparison below)
