根据生产发展需要,我厂最近引进奥地利艾协林公司生产的氮基保护气氛辊底式淬火炉热处理生产线。其中所用淬火油是至关重要的工艺材料,它直接影响零件热处理质量。因该设备处理的零件产量大、要求变形小,国外均采用快速光亮分级淬火油。但我国目前使用的分级淬火油,冷速较慢、光亮性差,不能满足大型淬火炉大批量连续式生产的需要。为此,我们以奥地利提供辊底炉淬火用的MARTEMP722快速分级淬火油(以下简称722油)的资料和技术指标为
According to the needs of the development of production, our factory recently introduced Austrian Aixin Lin nitrogen-based protective atmosphere roller hearth quenching furnace heat treatment production line. Quenching oil used in which the critical process materials, which directly affect the quality of parts heat treatment. Due to the equipment to deal with large parts production, deformation requirements are small, foreign countries are using fast bright quenching oil classification. However, the classification quenching oil currently used in our country has a slow cooling speed and poor glossiness, which can not meet the needs of large-scale continuous quenching furnace production. To this end, we provide Austria with roller hearth quenching MARTEMP722 rapid grading quenching oil (hereinafter referred to as 722 oil) and technical indicators for the
