一、技术改进的重要意义在粉末冶金工业中,约75％的能耗用于电炉中的烧结、渗碳和燕气处理。据日本住友电气工业公司和冈山精密电工两厂家的调查:以最普遍使用的网带输送式炉为例,在各加工过程中,70％能耗用于例如烧结、渗碳、蒸气处理之类加热工艺过程,而且消耗的能主要是电能和用于LPG(液态丙烷保护气氛)(图1)。另外还分析了在网带 First, the significance of technological improvements In the powder metallurgy industry, about 75% of the energy used for electric furnace sintering, carburizing and asbestos treatment. According to a survey by Japan’s Sumitomo Electric Industries and Okayama precision electricians, taking the most commonly used mesh belt conveyor furnaces as an example, 70% of the energy used during each process is for sintering, carburizing, steaming Class heating process, but also consumes mainly electricity and for LPG (liquid propane protection atmosphere) (Figure 1). In addition also analyzed in the net belt
