The Metallurgical Engineering Experiment Center undertakes all the specialized experimental courses (16 independent courses) for metallurgical engineering undergraduates. However, only four courses involve the application of large instruments, with the utilization rate less than 20%. It greatly reduces the opportunities for students to understand, operate, and use large instruments. Furthermore, most of the experimental courses involving large instruments just demonstrate how to use these instruments. To achieve better teaching effect in experimental courses, we combine the theories of metallurgical engineering with its technology research characteristics and apply large instruments in our undergraduate experimental teaching, relying on the National Teaching Demonstration Center of Metallurgical Engineering and guided by the Beijing excellent course " Metallurgical Engineering Experimental Technology". We also introduce advanced sample pre-processing skills and improve the analysis process of large instruments to make full use of curriculum resources in order to better infuse the educational idea of innovation and entrepreneurship education into the entire process of personnel training.

There are many problems in traditional metallurgical engineering experiment teaching such as expounding separated from operating, fixed experiment item and time, no preparing before class, lack of enthusiasm in group cooperation, single item etc. WeChat public platform supplies new idea for solving these problems. Taking "metallurgical process water model" for instance, WeChat public platform is established for this experiment class. Students can choose one from ladle water model, tundish water model and mold water model, design project, and group automatically by the WeChat public platform. Practice has proved that experiment topic could be expanded, student’s enthusiasm and initiative could fully be excited, cooperative spirit of group could be enhanced, comprehensive ability and innovation quality could be strained by this new experiment teaching program. Choosing topic based on Wechat public platform can be applied to other metallurgical engineer research experiments and the whole lesson of "metallurgical engineering experiment technique".

Imposed magnetic field is obtained by finite element software AN SYS for electroslag remelting process. These magnetic data are changed to M11D data format by the program developed by using C language. The induced magnetic field due to fluid motion is solved by FLUENT and M11D model with the imported external magnetic field data. The Lorentz force and the Joule heating as M11D results are added into momentum equation and energy equation as additional source terms. 3D flow and heat transfer models are established for electroslag remelting process. The calculated results show that the induced magnetic field is very small compared with external magnetic field, and may be neglected. Slag field vortices flow is mainly influenced by the Lorentz force and the buoyancy force only influences the flow near the wall. The Joule heating in slag field is much larger than that in metal field, and is enough for remelting electrode and droplets forming. The temperature field is stable and solidifieation interface is no more changed after 1 840 s. [ABSTRACT FROM AUTHOR]

For large sample data sets,traditional DKPCA occupancy a lot of computer memory and large computation,in order to solve these problems, this paper proposed an improved DKPCA based on effective feature subspace( EFS-DKPCA). The new method based on a orthonormal basis of the sub-space spanned by the training samples mapped onto the smaller feature space to simplify K,thereby reducing DKPCA computational complexity. When applied to process monitoring, the EFS-DKPCA-based method was more efficient in computation and needed less computer memory than DKPCA-based methods. Computer simulation of TE process demonstrates the effectiveness and efficiency of the proposed method. [ABSTRACT FROM AUTHOR]

The contents of oxygen and nitrogen in steel have detrimental effect on steel product quality，so it is important to determinate the content of oxygen and nitrogen in steel exactly for Steel Mill and relevant scientific research department. Instrument and sample all affect the accuracy of determination. The effects of sample preparation and sampling methods on oxygen and nitrogen analysis results for off-line determination is investigated such as style of getting spot sample，position of making sample stick，surface treatment，results handle and so on. It is show that block-shaped sample is better than disk-shaped sample for detecting oxygen and they are same for detecting nitrogen，eccentric cutting is better than radial cutting and centric cutting，oil dirt affects oxygen detecting result and has nothing to do with nitrogen detecting results，when avoiding sample polluted by oil ethyl alcohol cleaning effect is equal to acetone，special large data is not taken into account because of accidently occasion of large size non-metallic inclusions.

Tundish water model is widely used in metallurgical research work, but its experimental facilities' automatic level is not general high and stays at hand operating stage. There are many problems such as long time for preparing experiment, large system error and wasting water. According to tundish process,advanced meters and controlling valves and Siemens PLC are used. PLC program and operating interface are developed. Comparing with old water model equipment, the automatic control system enhances efficiency, saves water and reduces error. It has been successfully used in teaching and research. The automatic control system fully shows perfect combination between metallurgy experiment and automatic technology. It belongs to innovation and development of experiment field. It can guarantee the study on tundish water model successfully carried. [ABSTRACT FROM AUTHOR]
