深层高温快速渗碳是当前热处理技术发展主流,在1010℃以上高温渗碳比在850~930℃常规渗碳工艺时间缩短30%~50%以上,可显著降低成本和能源消耗[1]。由本公司为东汽集团东方汽轮机有限公司提供的高温渗碳箱式多用炉生产线在2010年3月投入使用,其最高工作温度为1100℃,最大装炉量可达 Rapid carburizing at high temperature and high temperature is the mainstream of current heat treatment technology. The carburization at high temperature above 1010 ℃ is more than 30% ~ 50% shorter than conventional carburization at 850 ~ 930 ℃, which can significantly reduce the cost and energy consumption [1]. The high-temperature carburizing box type multi-purpose furnace production line provided by Dongfang Turbine Co., Ltd. for Dongfang Group Co., Ltd. was put into operation in March 2010 with a maximum working temperature of 1100 ℃ and a maximum loading capacity of up to
