[Comprehensive] Guo Hongwei: Expert "Gold Workers"

Profile: Guo Hongwei, rooted in the production of electrolytic aluminum in the first line of 15 years, when the electrolysis workers at the grassroots level, concentrate on the post and concentrate on the technology. Starting from the workers at the most basic level, led the electrolysis workers to carry out the “triple optimization” test and successfully started 120 electrolyzers; the successful “multi-parameter balance” control technology experiment succeeded in greatly reducing the energy consumption of electrolyzers. , Aluminum ingots integrated power consumption dropped to 13400Kwh / t.AL, went to the domestic front. He became one of the major backbones of the company's electrolytic aluminum plant technology innovation, and made outstanding contributions to the technical output of the Chinese aluminum industry and the company's electrolytic aluminum reduction.

Ingenuity: Skywalker, gentleman should be self-reliant! Since we have made a choice, we must do a good job, and we must do a good job!

He graduated from college and later went to the electrolytic aluminum production line as an electrolysis worker; he applied for an engineer job and still carried out the "touch-bottomed" operation; he, with technology, went abroad to strengthen the country's aluminum electrolysis technology in the world. Lin Zhongzhe took a place to contribute; he, to overcome technical difficulties, a year to save 8 million yuan investment in the electrolytic aluminum plant ... ... He is China Aluminum Corporation Guangxi Branch electrolytic aluminum plant engineer Guo Hongwei.

Grinding in front of a tough environment

Guo Hongwei of medium build was prominent in the crowd because he was too skinny, and the skinny face of the cheekbone was high and raised. His eyes were dizzy, and his delicate white hair could not withstand the years and quietly climbed on his tail.

“How hard the electrolysis operation is, people can't understand it.” Guo Hongwei told the author that only the protective equipment used for the job is very heavy, with 4 pounds of heavy steel safety shoes and nearly 2 pounds of “pig nose” protective masks. Special work clothes, safety helmets and gloves add up to at least 10 pounds. "When I first joined the work, I was wearing these equipments to watch the master's operation. When one class came down, I was exhausted."

After graduating from university in 1999, Guo Hongwei worked with Pingguo Aluminum, which is renowned at home and abroad. Before the report, he had imagined his work scenario countless times: designing a plan in front of the computer, analyzing data in the main control room, or remotely scheduling the production... Imagination is wonderful, but the actual gap is huge. After Pingguo Aluminium, Guo Hongwei wore heavy work clothes and heavy insulated boots every day. Together with his colleagues, he repeated the heavy and boring work of the aluminum electrolyzers who had to touch the bottom of the tank, remove the carbon and replace the anodes.

Guangxi's summer heat is extremely hard, and it's hard to stay in the house. Every day it needs to work on the edge of a high-temperature electrolytic cell of nearly a thousand degrees Celsius. Together with dust and magnetic fields, Guo Hongwei is also confused. However, in 1999, Pingguo Aluminium succeeded in overcoming the 300-kiloampere-class aluminum electrolysis technology. The news spread rapidly at home and abroad, and experts and scholars came to learn. “The 300-kiloamp cell represents the top level in the world at the time. I am amazed and envious to learn the smelting profession and have just taken the job,” says Guo Hongwei.

In order to understand the structure and principle of the electrolyzer, Guo Hongwei often climbs to the top of a hot and dirty electrolyzer to study the structure and operation principle of the equipment. Although he was almost overwhelmed by smoke, he never gave up. In order to replace the anode carbon block, he faced the electrolyte at 960 degrees Celsius and baked it for about half an hour next to the electrolytic cell. A work flow was already sweating.

He Xinghong, director of the electrolysis plant's electrolysis process, said: “Guo Hongwei is a manager who has grown up from undergraduate students. He can bend down and completely integrate into the daily production operations of aluminum electrolysis. It is commendable. When he was operating as an assistant, He had long insisted on participating in the conversion work of four electrolyzers every day for a long time, and tolerated baking of molten aluminum flames for nearly a thousand degrees Celsius for a long time. His operating level was such that he “baked” up.

Difficult problem solving skills with technology abroad

After years of accumulation, in 2013, Guo Hongwei and his team successfully tackled the "double-balanced" energy-saving electrolyzers and high-energy tank technologies of large steel bars, which has always been something he has always been proud of.

“Electrolytic aluminum has always been a high-energy-consuming industry and the production cost is still high. I have always wanted to overcome this problem.” Guo Hongwei laughed. “The key to this technology is to use new materials to insulate the electrolyzer and make more heat. The retention in the electrolytic cell is used in production, but it cannot add too much thermal insulation material, excessive addition of insulation material will cause the electrolytic cell to leak, which can seriously lead to the collapse of the entire production line, resulting in great economic losses.How to achieve thermal insulation and safety Double balancing has become a difficult part of this technology," he told the author.

"My teammates and guards are standing around the two experimental electrolyzers in rotation 24 hours a day." In the six months of recalling the experiment, he broke his heart. On duty, he had to go to two test cell measurement data every hour, even after work, he called members of the shift from time to time to understand the situation. Hard work pays off, after more than six months of testing, this technology through the safety assessment, for the company to make great contributions to energy-saving emission reduction for the electrolytic aluminum plant a total of 8 million.

As Guo Hongwei’s technology is strong and the “difficult miscellaneous diseases” in production technology can be solved, from 2006 to 2012, Hepingguo Aluminum Electrolytic Aluminum Experts went to the Indian two-aluminum enterprises five times to carry out technical assistance work, with a performance assessment of 94.18. The current efficiency of 13% and the direct current consumption of 13401Kh/t.Al have been highly recognized by the Indian side. It has made outstanding contributions to the success of China's aluminum industry technology and its place in the world's strongest aluminum electrolysis technology.

In 2006, Balco Aluminum Company of India caused a large area of ​​troughs due to power outages. Indian workers had an explosion during the process. Guo Hongwei also saw the scene of the explosion. “You can see from the mobile phone video recorded by Indian workers that when the liquid splashed out, like firecrackers, the entire workshop was full of sparks.” Describes the scene at that time, leaving him with an oversight and an unforgettable moment. This also made him aware of the importance of safety in production. After the end of the foreign aid service, the first thing he did after returning to the company was to work out with his co-workers based on his experiences in dealing with abnormal conditions and emergencies at Balco Aluminum in India. Detailed emergency plans and lessons learned from other workers.

Hongwei Guo, the old monitor of the same year, Tang Yuesong recalled: “He had time to read the technical book and turned a blue-leaved electrolytic aluminum technology book all over. He also loved to make work notes. Where did he go?” Guo Hongwei Bringing love to work notes to India."

Inheritance of "artisan spirit" team "flowers bloom"

Standing up to the backbone of China Aluminum is relying on craftsmanship. "Heavenly days, gentlemen should be self-reliant! Since they have made a choice, they must do a good job, but also to do a good job!" Today's Guo Hongwei is already a veritable "gold medalist."

At this point, he turned his attention to his younger colleagues. In his eyes, one person is not a good one. A good team is really good. In 2013, under the support of China Aluminum Guangxi Branch’s trade unions, the “Great Worker Model, Gold Workers Innovation Studio” named after Guo Hongwei was established. All members of the Innovation Studio are guided by the guiding ideology of “transmitting skills, technological innovation, building elites, and improving management” and carry out activities such as mentoring, technology research, and technological innovation.

From him, we not only saw his morality as an elder, but also his character as an engineer. In the past three years, the studio has carried out 36 training courses on electrolytic aluminum technology and 1,000 people participated in the training. It has trained 10 gold medal workers, technicians and 12 young aluminum electrolysis experts. These technical experts have gone to the national electrolytic aluminum plant and foreign electrolytic companies. Technical output, they use their own superior skills and expertise to increase revenue for the company, fully reflects the good effect of the talent elite team effectiveness. Guo Hongwei presided over and participated in more than 10 technological transformations and scientific research projects, participated in the research and application of dozens of new technologies and new processes, and solved more than 50 production and technical difficulties in large and small sizes. Guo Weiwei’s apprentice Huang Weizhuo was honored as a 2013 gold medalist by the company. The disciple Tang Wei was among the best in a variety of technical contests. He was assigned to domestic and foreign aluminum factories for technical exchanges and guidance work and received various manufacturers’ Praise.

Continuous innovation and forgetfulness are the shortcuts for Guo Hongwei's success. Today, he has become a real gold medalist. Electrolytic aluminum has also become a part of his life.
