Exploration of Experimental Teaching Reform in Metallurgical Engineering Based on Equipment Optimization

In the context of the vigorous advancement of China’s “Double First-Class” initiative, upgrading experimental teaching equipment in metallurgical engineering holds significant importance for enhancing undergraduate experimental teaching quality and strengthening talent cultivation. The School of Metallurgical Engineering at Northeastern University has optimized experimental procedures, improved efficiency, and enhanced data accuracy by updating and adding instrumentation for courses such as Engineering Thermodynamics, while introducing computer-controlled systems and data acquisition systems. Addressing the limitation of the original melting point and melting rate tester, which lacked atmosphere control capabilities, a controlled-atmosphere testing chamber was independently designed and developed. This enables melting point and melting rate testing and analysis under controlled atmospheric conditions, accurately measuring the melting points and melting rates of various metallurgical materials with complex compositions and differing properties. It provides more reliable data support for related research and experimental teaching.
