摘要
热处理炉,尤其是渗碳及淬火炉,都是连续不断地向炉内通入工艺气体。尽管工艺气体的消耗相当可观,也是热处理成本的一部分,但到目前为止,所通入的工艺气体都是通过废气口烧掉了。本文所述的技术是将工艺气体催化再生后,再送回热处理炉中,渗碳淬火炉的工艺气体消耗量可节省高达90%。本文重点介绍了新的再生技术的概念、实施以及工业应用的效果。
Heat treatment furnaces, especially those for carburizing and hardening, utilize a continuous gas flow through the furnaces. Despite the fact that the consumption of process gas is considerable and re- presents a certain cost factor in heat treatment, the flue gas of heat treatment processes is up to now use- lessly burnt-off. A new technology uses the catalytic regeneration of the process flue gas, brings it back in- to its original state and returns it back into the heat treatment furnace. This reduces the process gas con- sumption of carburizing and hardening furnaces up to 90%. Concept, execution, and functioning of this new regeneration technology together with results of its industrial utilization are the main focus of this pa- per.
