In order to comprehensively improve the level of aluminum melting and casting in China, build a green and low-carbon digital melting and casting, and carry out real-time scientific digital control of melt purification effect, June 14-16, Fujian Micro Testing Co., Ltd. held a three-day training course on hydrogen PreFA slag testing in aluminum melt, 3D high-power organization of slag testing and metallurgical defect analysis in Fuzhou University and National University Science Park. Nearly 50 students from aluminum alloy smelting and casting enterprises and related institutions from all over the country participated in the training.

The training, the organizer of Fujian Micro testing Co., Ltd. invited the internationally famous aluminum testing alloy organization analyst, the United States University of Kentucky aluminum Technology Center chief engineer, the United States SECAT testing company chief expert Wen Xiyu postdoctoral, Lin Lin, chief engineer of Chalco Group, chief expert of the National 863 Program "Deformed aluminum alloy and forming processing technology" project leader, China light metal expert, high-level Class A talents in Fujian Province, Fuzhou government consultant, Chongqing Guochuang Light Alloy Research Institute Co., Ltd. melting and casting professional direction expert Ke Dongjie as a mentor.

University research experts, production quality control experts and comprehensive experts in production and research to form a mentor group, strong and strong joint, to participate in the training of students for professional guidance.

In the class, the teachers and students had interactive exchanges on the causes, forms, effects on product quality and solutions of slag, impurity and gas in aluminum melt.

After the theoretical study, the expert team carried out the practical operation of preFA slag measurement of aluminum melt, the 3D high-power organization of slag measurement and the on-site demonstration of metallurgical deficiency analysis. While guiding the students in practical operation, they jointly discussed the problems encountered in practical work, focusing on the common problems existing in the field of aluminum melting and casting in the country, that is, the difficulties of online hydrogen measurement and offline slag measurement. And for the students to find a path to solve the difficulties.

Fujian Micro Testing Co., Ltd. is the only testing institution in China that covers the detection, analysis and evaluation of metal solid and high temperature liquid at normal temperature, which was established by the national 10,000 people Plan talent Ke Dongjie. At present, the company's ability to detect and evaluate the purity of molten materials is the most complete and strongest in the country, and it takes the lead in the country to carry out the evaluation standards for the purity of aluminum melt and establish a digital gene bank for aluminum alloy materials. After years of efforts, with the continuous enhancement of the development ability of consulting projects, the current business covers the determination of hydrogen content of aluminum melt, the determination of aluminum melt slag content, aluminum composition analysis, etc., promote the construction of digital gene bank of aluminum alloy in China, and have good visibility and authority in the aluminum processing industry.

In this training, the students came to the laboratory of Fujian Micro Detection Co., Ltd. to visit the latest equipment for aluminum detection such as laser spectrometer, scanning electron microscopy, gold sample Mosaic machine.

Casting process is the "life" starting point of metal materials, strict control of material hydrogen content and impurity content, is a particularly important technical index for the production and preparation of aluminum alloy materials, therefore, the establishment of strict online hydrogen and offline slag testing, real-time scientific digital control, is to eliminate inappropriate hydrogen and slag aluminum alloy production and casting necessary and scientific means. It can greatly improve the utilization rate of materials and the yield of post-processing products, laying the foundation for the development of material genome and intelligence, and laying the foundation for the digital transformation of China's aluminum industry.

During the visit, the students went to the National Science Park of Fuzhou University and visited the Digital Fujian Research Institute of Technology, and personally experienced that "Digital Fujian is the ideological source and practical starting point of digital China".

Three days of training, great response, the students gained a lot, full of confidence in China Aluminum. Ke Dongjie, founder of Fujian Micro Testing Co., LTD., said that such training has been held a number of times, and will be held and promoted across the country in the future, so that the real-time scientific digital control of melt purification effect will enter the aluminum manufacturing enterprises, and make greater contributions to China's aluminum processing and casting.

▲ Certificates of completion were presented to the students
