High-quality development is the last word in the new era, and the profound transformation of traditional industries is an extremely important chapter in the grand symphony of developing new quality productivity.
Intelligent tunneling robot "deformed gold steel" in coal mine

Shaanxi Xiaobaodang Coal Mine, 400 meters of formation, shearers are mining coal.
The 1.8-meter-diameter steel giant ship drives 66 coal cutter heads to work at a speed of 10 meters per minute, with a daily mining capacity of up to 46,000 tons.
Traditional industries that have lasted for hundreds of years are transforming to high-end, intelligent and green, and new production methods have given new vitality to fossil energy.
This is China's first 450-meter-long intelligent coal mining equipment.
The shearer cuts horizontally along the coal seam, the cutter head rotates forward one meter, and the bracket like a big foot plate follows up one meter, supporting the roof to prevent collapse, and the conveyor synchronously conveys the broken coal.
Intelligent coal mining, with the full cooperation of man and machine, is the safety and efficiency that traditional coal mines have never had in the past.
Before coal mining, the first thing to do is to build a roadway. The roadway is a necessary passage for coal mining, which undertakes the functions of transportation, ventilation and drainage.
This is the TBM for mining the roadway. The walking of this square shield machine is done through the shield of the head. The upper and lower layers of the shield body move alternately through the expansion and contraction of the internal hydraulic cylinders, and at the same time play the role of support, and drag the excavation forward.
The body is more than 100 meters long, like a steel dragon, shuttling through the underground coal seam and drilling out of the roadways.
The renewal and consolidation of traditional industries and the development of new quality productivity according to local conditions are becoming an important password for the high-quality development of industrial equipment.
Today, more than 2,500 mining faces across the country have completed intelligent upgrades, and the mechanization degree of large-scale coal enterprises has exceeded 79%, and they have jointly built an underground steel Great Wall.
How can 99.99% gold purity be achieved with offshore steel up to 100 mm thick?
The 37,000-ton Haiji-2, Asia's largest deepwater jacket, has reached a depth of 300 meters in the Pearl River Estuary Basin, developing the mainland's first deepwater oilfield. In order to solve the problem of flexible deformation of ultra-large deepwater jackets, domestic high-strength offshore steel was used on a large scale for the first time, reducing the project cost by 100 million yuan, and at the same time overcoming the key technology of lightweight design of ultra-large offshore platforms.
Gaoqiang Offshore Steel comes from a little-known steel mill in Xiangtan, Hunan. Walking into the five-meter-wide steel rolling workshop, it is the production line of Haiji No. 2 steel plate, a billet weighing 20 tons, after heating, rolling, finishing, inspection and other processes, becomes a marine steel plate, with a maximum thickness of 100 mm.
It is even more difficult to refine such high-purity steel than alchemy, and the reason why we dare to take on this project is due to the digital upgrade of the production line.
Steel has been in service for a long time in the deep sea of 300 meters, not only to face the undercurrents of the waves, but also to overcome the corrosion of seawater, and the whole life cycle, without producing any minor defects. In order to meet these harsh conditions, Hunan Iron and Steel Group and experts from scientific research institutes overcame difficulties for three months to make the uniformity of steel plates with a maximum thickness of 100 mm comparable to that of aircraft carrier steel.
"Vertical production" intelligent equipment covers all spinning links
Iterative upgrading, the launch of high-end products is not only steel, but also the textile industry, which has been shuttling between warp and weft for hundreds of years, is also driven by new technologies to glow with new colors.
In Shengze, Wujiang, Suzhou, a textile professional town, more than 100 textile factories are busy building factories and replacing machines.
In this Song Jin fabric processing factory, the old machine has not had time to be moved, and the new equipment is already at full power. The new machine, with its 20,000 stitches, is capable of weaving more than 800 continuous and complete patterns on a 1.4-meter-long brocade, which was not possible with the previous equipment.
In the new "vertical production" plant, from the first floor to the top floor, intelligent equipment covers all spinning links.
Yarn breakage used to be the biggest headache in textile mills. Manual knotting is not only inefficient, but also affects the quality of the fabric. Now, the new device with an intelligent identification system can accurately identify broken yarns and then automatically join them with a robotic arm.
After all the 134 intelligent devices in the entire workshop are connected to the big data platform, the output of the equipment, the efficiency of operation, and all the data can be clearly presented on the large screen of the office.
From a cotton flower to a strand of silk, from a gram of coal to a kilowatt-hour of electricity, from a piece of iron ore to a piece of offshore high-strength steel, traditional industries are the "basic disk" of the real economy, and they can also be the "main battlefield" of innovation and change. In the face of the rolling tide of the development of new quality productive forces, the pressure will be changed into power, and the shortcomings will be changed into potential, and the old trees will give birth to new branches, and the new shoots will grow into big trees.
