At present, Nangang has built a 5000 mm wide plate and a special demonstration intelligent workshop, and at the same time increased the research and development of the use of robots, forming a unique development path of intelligent manufacturing of Nangang.
The production of marine steel plates uses "internet thinking" and the products of steel companies can also be customized... In the Nangang Group, through the guidance of intelligent manufacturing, these have become a reality.
Huang Yixin, chairman of the Nangang Group, said that personalized customization and large-scale production are a contradiction for steel companies. Personalization will inevitably lead to the fragmentation of orders. Taking the 300,000-ton VICC tanker as an example, according to the traditional model, a whole ship customer needs about 500 specifications of ship plates. Now the shipyard implements segmented lean production, and one ship has more than 2,800 specifications for steel companies. For steel companies, a furnace steel is 150 tons, and a piece of steel plate is only a few tons, and some steel plates are even half a sheet. Such orders cannot be produced according to the traditional scale method.
Create a "smart life body" of the enterprise. Nangang opens the road of intelligent manufacturing
In response to this problem, Nangang has built a “C2M (Customer-to-Factory)†system in the past two years, and has taken the lead in the steel industry to implement a new model of customized distribution of shipboards based on “Internet thinkingâ€. Specifically, after an enterprise receives an order through an e-commerce platform or other channels, the system will decompose the sales order into the internal production process, and then produce the personalized needs of the customer through lean production technology, such as “mosaic†panel production. product. "
In the past, customers only got the standard size steel plates, and they needed to cut them to the required size. It was a waste. The combined production of 'mosaic' is based on customer's customized requirements. Nangang will produce a number of different product specifications for one steel plate to correspond to orders from multiple users. "Nangang wide plate staff told reporters.
Even in the early design stage of the shipyard, Nangang intervened in the early stage of communication to help customers optimize the plan and make the design that can optimize the steel production. On the one hand, it can reduce the cost of customers. On the other hand, Nangang can also make the cost according to the customized production. Require customers to give appropriate returns. Through pre-intervention and immediate delivery according to the customer's production plan, the customer reduced the steel plate reprocessing, the steel utilization rate increased from 90% to 95%, the inventory decreased from the original 2 months to 7 days, and the shipbuilding manpower saved 1/3.
This "intelligence" system is not only the performance. On the e-commerce platform, in addition to the specific product requirements for Nangang, the customer can also make suggestions and even observe the production process through VR, and monitor the production status of the order in Nangang through the mobile terminal; Orders, the system has a self-assessment function, to assess whether this single can not pick up, what price should be, when the delivery date is appropriate; for the customer's integrity or not, there is also a set of evaluation system. At present, this customized production model has been successfully extended from shipboard production to steel “big†industries such as wind towers, structures, bridges, buildings and energy.
Intelligent manufacturing is inseparable from the application of robot systems. The steel industry is a high-temperature, high-risk, high-noise industry, especially in the temperature measurement and sampling processes of steelmaking. In August last year, a red “skin†six-axis robot was officially unveiled at Nangang, and the temperature measurement and sampling with high risk factors were successfully completed. The full name of this robot system is "liquid molten metal temperature measurement sampling robot in the smelting process". At the same time, the “Experimental Testing Center Automatic Tensile Testing Robot System†was independently developed, designed and implemented by Jiangsu Jinheng Information Technology Co., Ltd., a subsidiary of Nangang. This is the first self-developed and integrated automatic tensile test of domestic steel enterprises. The robot system can reduce the manual position and labor intensity of the tensile test and ensure the stability and reliability of the experimental data. According to reports, in the next three years, Nangang will be equipped with multiple robots in the production line, with point and face, steadily advancing, intelligently transforming more stations, and gradually realize the replacement of labor by machines.
“Nangang’s goal is to lead the smart manufacturing industry and create a “smart life bodyâ€.†Huang Yixin said that the enterprise’s “smart life body†is an intelligent enterprise operation ecosystem, which provides a more thorough perception and measurement, and more comprehensive interconnection. More in-depth intelligence. Through the creation of “smart life bodyâ€, building an intelligent dynamic business mechanism can help companies reduce costs and risks, and constantly evolve the way individuals, enterprises, customers, society, natural systems and man-made systems interact, so that business processes are clearer and more operational. Efficient and responsive to the market faster.
Octagonal Pole
Octagonal telephone pole is a telephone pole with eight sides, giving it a unique octagonal shape. These steel poles are often used to support power lines, street lights, and other electrical infrastructure. The octagon provides additional strength and stability compared to traditional round poles, making it ideal for areas with strong winds or other environmental challenges. Depending on the specific requirements of the installation, they are usually made of materials such as wood, steel or concrete.
