石墨流动粒子炉是使被加热的工件在导电的流态化石墨粉中,通电加热的新装备,具有升温快、节电、炉温均匀、无腐蚀性及脱碳还可兼作化学热处理之用的优点。本文介绍了流态化原理、耐热钢炉膛、工艺特性、实际使用情况、优缺点等。重点介绍了他们对炉膛、电极布置、透气板、石墨粒子的选用等方面的改进情况。 Graphite flow particle furnace is to make the heated workpiece in the conductive fluidized graphite, the new equipment energized heating, with fast heating, power saving, uniform temperature, non-corrosive and decarbonization can also double as chemical heat treatment The advantages. This paper introduces the principle of fluidization, heat-resistant steel furnace, process characteristics, actual use, advantages and disadvantages. The emphasis is put on their improvement of the furnace, the electrode arrangement, the air-permeable plate and the selection of graphite particles.
