Experimental Study on Seismic Resistance of Crucible Cooling Device for Vacuum Electron Beam Melting Furnace
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.
