HR_E合金是一种稀土含量较高的铁铬铝电热合金。主要具有以下几个优点:一高温抗氧化性能好;二高温蠕变小;三高温长时间使用后的冷脆性小。适用于各种电加热炉。曾于1980年获北京市科委、中国科学院、国防科委的奖励。1982年正式发表于《科学技术研究成果公报》。 本文主要介绍HR_E合金的主要特性。供从事电加热炉设计和研究的人员及我们的同行们参考。
HR_E alloy is a high content of rare earth iron chromium aluminum electric alloy. Mainly has the following advantages: a high temperature oxidation resistance; two high temperature creep small; three high temperature after a long time cold brittleness. Suitable for all kinds of electric heating furnace. He was rewarded by Science and Technology Commission of Beijing Municipality, Chinese Academy of Sciences and National Defense Science Commission in 1980. 1982 officially published in “scientific and technological research results bulletin.” This article describes the main characteristics of HR_E alloy. For electric heating furnace design and research personnel and our colleagues for reference.
