一、概述锻压少无氧化火焰加热是适应少无切屑加工和精锻工艺要求的一种加热方法.它不仅可以减少金属氧化量,而且对于延长模具寿命有良好作用.采用无氧化加热时锻模寿命大约提高16%.同一种坯料在连续炉、半连续炉和室式炉等火焰炉中普通加热时金属的氧化烧损量见表l. First, an overview of Forging less non-oxidizing flame heating is to adapt to less no chip processing and precision forging process requirements of a heating method, which not only can reduce the amount of metal oxide, but also to extend the life of the mold has a good effect. Life expectancy increased by about 16% of the same kind of billet in continuous furnace, semi-continuous furnace and chamber furnace flame furnace ordinary heating oxidation loss of metal in Table l.
