Carry forward the spirit of craftsmen, they write the glorious chapter of the times in ordinary positions
In recent years, a series of important weapons of great powers, super projects one after another, and scientific and technological achievements are all inseparable from the silent dedication and diligent pursuit of craftsmen from great powers with superb skills and excellence.
Socialism is done. On this May 1st International Labor Day, the winners of the "National May 1st Labor Medal" and "National Workers' Pioneer" stick to their ordinary posts, devote themselves to the hot practice of Chinese modernization with labor, and promote the transformation of Made in China into China's Creation transformation, and make unremitting efforts to comprehensively promote the construction of a strong country and the great cause of national rejuvenation.
Walking into the factory building of the Institute of Nuclear Physics and Chemistry, dozens of large-scale equipment stood side by side. Zhang Shijun, chief technician of China National Nuclear Corporation, who had just won the "National May 1st Labor Medal", stood in front of the CNC machine tool, focusing on the control panel, thinking and adjusting the production parameters. The start button was pressed, and the machine tool started running rapidly. Zhang Shijun sprayed coolant into the raw material processing cavity from time to time. After a few back and forth, an ultra-thin-walled part with fine craftsmanship was brand new.
Nuclear fuel is the "food" of the nuclear industry, and the nuclear fuel cycle is an important foundation for the development of the nuclear industry. Since joining the work, Zhang Shijun has devoted himself to practicing his turning technology based on his position, and is responsible for researching the processing technology of thin-walled key parts of special equipment.
Faced with the world's difficult problem of processing ultra-thin-walled cylindrical parts with special equipment less than the thickness of a piece of A4 paper, Zhang Shijun and his team went through repeated calculations and experiments, and after more than 1,000 days and nights of hard work, based on the structure and structure of the parts In terms of processing points, a key clamping method of "thermal expansion and contraction" was innovatively designed to achieve trial production of ultra-thin-walled parts, ensure the smooth implementation of relevant scientific research tests, and promote the development and industrial application of special equipment for uranium enrichment. It is of great strategic significance to ensure national energy security and the sustainable development of nuclear power.
"A drop of water can survive only by integrating into the sea and set off huge waves. Similarly, a person can only grow by integrating into a team." Zhang Shijun said. After more than 30 years in the job, Zhang Shijun has inherited the spirit of the nuclear industry. One person leads a group, and he has trained 11 senior technicians and 38 technicians, promoting the inheritance and development of production and processing technology know-how and experience.
"A craftsman should do ordinary things with peace of mind and build a fine soul with exquisite workmanship." For thirty-five years, Zhang Shijun and his team have been silently exploring and working in the ocean of special equipment processing and manufacturing, using their wisdom and sweat to help the development of my country's nuclear industry.
Weaving a “protective net” for the safe and stable operation of hydropower units
When walking into the office of Lv Xiaoyong, director of the electrical maintenance department of Yangtze Power Gezhouba Power Plant of China Three Gorges Corporation, what comes into view are three electrical main wiring diagrams of Gezhouba Power Plant hanging on the wall. The electrical symbols of important equipment such as generator sets and transformers are scattered throughout them.
"This is our magic weapon for electricity production. Hanging it here is both beautiful and practical." Lu Xiaoyong introduced.

Lu Xiaoyong, who is in his 40s, has been working with hydroelectric generators for 28 years and has witnessed the transformation of my country's hydropower industry from "following" and "running parallel" to "leading", and he has also grown into an expert in the relay protection industry. In 2024, he won the title of "National May Day Labor Medal".
"The honor not only belongs to me, but also to us Three Gorges people. This honor is the country's affirmation of the Three Gorges spirit with the core of 'for our China, to build the Three Gorges'." Lu Xiaoyong said.
In 2002, the first batch of units of the Three Gorges Power Station were ready to be installed, and professional talents were urgently needed. Lu Xiaoyong successfully passed the exam and became a Three Gorges Project builder. "When we first took over the mobile phone group, we encountered many problems and challenges. We often studied the problems in the office, looked up information, discussed with each other, and even consulted experts to find ways to solve professional problems one by one." Lu Xiaoyong said, "Every time we solve a Problems in the professional field make us feel fulfilled and full of accomplishment.”
On May 1, when I walked into the Qidashan Iron Ore Intelligent Management and Control Center of Anshan Iron and Steel Mining, I saw a large electronic display screen clearly showing the panoramic view of the stope. The busy working scene of the mine came into view, and various production data and equipment information were displayed on the screen. Keep flashing.
Ma Liancheng, winner of the "National May 1st Labor Medal" and chief engineer of the equipment room, is analyzing the operating efficiency of various equipment in the stope based on screen information, and allocating equipment tasks scientifically and rationally. This is the 27th time that he has spent the May Day Labor Day at his job.
"There is no limit to the sea of learning, but diligence is the only shore; there is no road to the clouds, but ambition is the ladder." This is Ma Liancheng's favorite ancient saying. Since joining the workforce, Ma Liancheng has devoted all his energy to work and study, and "52, black and white" has become the norm.
He began to study the positioning system of the cloth trolley in 1998. By 2018, he achieved the precise positioning of the cloth trolley by using carrier-free technology, directly creating more than 2 million yuan in benefits for the company; he created a metal detector that can detect manganese steel parts, solving the problem The problem of manganese steel parts passing through the Qidashan Iron Mine's beneficiation crushing and northern crushing has greatly improved the production operation rate, and the annual profit has reached more than 10 million yuan; he researched the safety technology and control technology of the belt system, realized the safe, stable and smooth operation of the belt system, and improved the efficiency of the belt system. Productivity and effectiveness…
In 2021, as the person in charge of the Qidashan Iron Mine Smart Mining Project, Ma Liancheng decomposed the overall project into 18 sub-modules, drawn up 456 progress sub-items, and refined the construction period and quality standards. At the same time, the company leveraged the technical advantages of Ma Liancheng's innovation studio to build an efficient, green and intelligent new production management system for mines, and achieved the first "one-to-two" remote control of cone drilling rigs in the industry, digitizing the entire mining production process and creating a reliable Copy smart mining projects.
"A single beautiful branch is not spring, but a hundred flowers blooming together fills the garden." In 2014, Qidashan Iron Mine established an innovation studio named after Ma Liancheng. Up to now, Ma Liancheng Innovation Studio has obtained a total of 85 invention patents, 37 proprietary technologies, 48 major rationalization suggestions, and a cumulative innovation benefit of more than 50 million yuan.
The high temperature of 1600°C, the three kilns with daily melting capacity of 560 tons/600 tons/950 tons, and the fiery lava are their smoke-free "battlefield"; raw materials, melting furnaces, tin baths, annealing and cold ends, 500 meters long The production line is the "position" where they fight day and night; the glass as sharp as a sword, as thin as a cicada's wing, and crystal clear glass is the "harvest" of their hard work day after day... They are the "National Worker Pioneer" production and operation of Yaohua Glass Co., Ltd. department.
