“Flying towards the ‘hot and spicy’ Hunan”
“I used to think that I was good at eating spicy food, but the first bite I took of the slightly spicy Malatang when I came to Hunan made me burst into tears. I will never do it again. Dare to speak!” When
met Liang Yongqi for the first time, this gentle and lively young man told reporters about his “embarrassing stories”.
While studying for a postgraduate degree at Beijing Jiaotong University, by chance, he participated in a job fair held by the CRRC Zhuzhou Institute team at the school. In less than an hour of interaction with
, he was deeply moved by the charisma, simple feelings, cutting-edge technology and broad platform displayed by the recruitment team. For this reason, he declined the opportunity to study in Beijing and receive high salary from coastal companies.
"While you are young, you should try your luck!" Some students were puzzled, while some friends persuaded him. Liang Yongqi admitted that this choice was indeed a big challenge, but he always firmly believed in his choice. Before
left, the instructor told him based on his personal experience: Zhuzhou is a good place that is definitely worth visiting. It has two distinctive features, one is hot and the other is spicy, so you must be prepared.
With hope and blessings, this young man born in Shangqiu, Henan Province in 1996 resolutely rushed to the "hot" Hunan.

"Struggle, I became us"
Liang Yongqi still clearly remembers that when the COVID-19 epidemic broke out, as a newcomer, he was responsible for the management of departmental materials while working in the factory.
It seems to be a very simple job, as small as a bucket of instant noodles, a pair of socks, as large as a set of quilts and a mattress, but Liang Yongqi does not dare to relax at all. From counting the supplies to distributing them, plus volunteer work and his own work, he had to be busy until after 11 o'clock every night. He was so exhausted that he often lay down to rest without even taking off his clothes.
company has established mechanisms and platforms such as "mentors and apprentices" and "youth innovation studio", and accurately implemented a series of team integration, industry integration, job integration and other measures, giving Liang Yongqi the opportunity to better use his youthful wisdom and create youth value.
While he humbly asked his seniors for craftsmanship skills and management problems, he also imparted his experience to new employees without reservation. From the new employees recruited by the school every year, Liang Yongqi not only sees himself, but also sees the future of the company.
Whether it is the "hard core" spicy crayfish or the "fragrant" chili fried pork, they have become Liang Yongqi's favorite. The Hunan culture of "hardship and patience" that he came into contact with in work and life also made him gradually understand that it is not only the Hunan flavor that is hot, but also the Hunan spirit.
"In giving and dedication, in hard work and struggle, I became us." Liang Yongqi said that the process of struggle is painful and happy. Although it is tiring sometimes, a simple "Thank you, thank you for your hard work" can make you full of energy, because your "circle of friends" is integrating more good friends.
"Chasing dreams, installing 'Chinese core' for high-speed rail"
In the traction electric transmission system that provides continuous power for high-speed rail, there is a palm-sized igbt module, which controls the "lifeblood" of vehicle automatic control and power conversion. , is the "heart" of high-speed rail.
is such a core component, but it has been dependent on foreign imports for many years. General Secretary Xi Jinping said that "key core technologies cannot be obtained, bought, or begged!" This is also the most prominent thing hanging at the entrance of the company. Discourse. The lifeblood cannot be in the hands of others. We must take the path of independent research and development of igbt.
Liang Yongqi's team is a "youth special team" with 70% of the youth under the age of 35. After passing on technology from generation to generation, the team has always insisted on pursuing the dream of "Chinese Chip" and concentrated on the research and industrialization of igbt power semiconductor technology. .
Due to very limited testing resources, in order to conquer the core technology as soon as possible, the team often stayed in the laboratory for a whole day, drinking cold water when thirsty, gnawing bread when hungry, and staring at the research objects with a microscope, often with red, swollen and painful eyes. The production time of
chips is often calculated in months, and the error correction time is even longer. From the laboratory to mass production, team members often turn on the "24-hour operation" mode for several months in a row, verifying, analyzing, fine-tuning, verifying hundreds of parameters such as temperature, air flow, and process time over and over again... until they find the perfect solution. Excellent solution.
In the end, from thyristor products, fully crimped devices, fully crimped high-voltage and high-current devices to the current igbt chips, batches of young people continued to work hard to tackle key problems, breaking through blockades and monopolies step by step, and finally overcame key core technical difficulties. The self-developed igbt allows China's high-speed rails running around the world to use "Chinese cores".
At present, the team has launched the seventh generation igbt technology, many of which are original and original. The product performance has reached the international leading level. The products are also widely used in smart grids, new energy vehicles, new energy equipment, high-end industries and other fields to achieve Developed its own igbt chip to "make up for the shortcomings".
"The road is long and difficult, but the journey is coming; if you keep on walking, the future is promising." Liang Yongqi said that this is his favorite sentence, and it was also the sentence he used at the end of his defense for becoming a full-time employee of the company.
