摘要
自主研制了一种坩埚冷却装置,用于真空电子束熔炼炉中坩埚的安全冷却.本文对该坩埚冷却装置进行了抗震鉴定试验,测试了坩埚冷却装置在抗震试验前后的共振频率,并利用地震台进行了 5次运行基准地震试验和1次安全停堆地震试验.试验结果表明:该坩埚冷却装置具有足够的抗震强度,能够在规定的地震条件下正常运行,满足抗震性能要求.
Abstract
A crucible cooling device used to safely cool the crucible in the vacuum electron beam melting furnace was independently developed by the institute of physical and chemical engineering of nuclear industry.In this paper,the seismic identification test of the crucible cooling device was carried out.The resonance frequency of the crucible cooling device before and after the seismic test was measured,and five operation benchmark seismic tests and one safe shutdown seismic test were carried out by seismic station.The test results show that the crucible cooling device has sufficient seismic strength,and can operate normally under the specified seismic conditions to meet the seismic performance requirements.
