A roll of copper tubes with different thicknesses are "spewed out" from the machine, and data such as energy consumption and production line status are generated in real-time on a large electronic screen. Intelligent monitoring can provide early warning of safety production risks... Entering Pinghu Jinlong Precision Copper Tube Co., Ltd. in Wanzhou District, Chongqing, there are only a dozen workers in the vast digital workshop who are inspecting or operating equipment. Pinghu Jinlong mainly produces high-precision copper tubes for air conditioning and refrigeration. Zeng Qingyou, the director of the production technology department of the company, told reporters that through the application of 5G+industrial Internet technology, the company has achieved unmanned batching, handling, and warehousing, with a production efficiency increase of 10%. Last year, it produced about 70000 tons of copper tubes, an increase of about 12% compared to the previous year, effectively improving the competitiveness of the company. In Wanzhou District, more and more enterprises are experiencing the benefits of digital technological transformation. In recent years, Wanzhou District has focused on building leading industries such as intelligent equipment, food and medicine, and new materials, promoting the regional economy to "accelerate" through digital and green technological transformation. Gao Bangyuan, Deputy Director of the Economic Development Bureau of Wanzhou Economic and Technological Development Zone, introduced that Wanzhou Economic and Technological Development Zone has taken the upgrading of digital intelligence technology as an important starting point for cultivating advanced manufacturing enterprises. In 2022, it guided 25 industrial enterprises to implement 33 digital intelligence technology transformation projects, newly cultivating 22 specialized and specialized new enterprises, 15 national high-tech enterprises, and 22 technological enterprises, with a total of 6 digital workshops built. At present, in Wanzhou Economic Development Zone, a number of environmental protection and energy conservation projects such as the disposal and utilization of solid wastes such as fly ash and waste heat power generation are accelerating construction. Chongqing Jiulong Wanbo New Material Technology Co., Ltd. is an aluminum oxide production enterprise that was put into production last year. In the company's product exhibition hall, a large iron ingot refined from red mud is very eye-catching. Red mud is a waste generated during the production of aluminum oxide. Due to its complex composition and high disposal costs, how to reduce environmental risks of red mud is a long-standing issue in the aluminum industry. "Red mud contains a large amount of iron oxide, which can completely turn waste into treasure. My main focus now is on the recycling and utilization of red mud." Chen Guoyou, General Manager of Kowloon Wanbo, introduced that through joint research by enterprises and relevant scientific research institutions, about 3 tons of red mud can be refined into 1 ton of iron. The enterprise's "red mud ironmaking" project has entered the industrial trial stage. This is due to the research and development of green and low-carbon technologies and the construction of Chongqing 5G+innovation demonstration smart factory project. Currently, the enterprise has enjoyed a booming production and sales, with an output value of over 8 billion yuan last year and is expected to exceed 10 billion yuan this year. Some enterprises, especially small and medium-sized enterprises, lack funds and resources in the process of digital and green technological transformation. What should they do? Wanzhou Economic Development Zone established Chongqing Three Gorges Green Intelligent Manufacturing Empowerment Co., Ltd. in June last year to provide consulting services for enterprises under its jurisdiction. "We have cooperated with many well-known Internet and electrical equipment companies to reduce the cost of intelligent low-carbon technological transformation of enterprises through energy management contracts, energy-saving equipment leasing, and financing. Currently, we have provided energy consumption diagnosis, digital transformation, and other services to more than 20 industrial enterprises in the Economic Development Zone, and completed more than 10 rooftop photovoltaic projects." Xiong Qiong, the general manager of the company, said. In 2022, the industrial output value of Wanzhou Economic Development Zone was 41.6 billion yuan, a year-on-year increase of 35%. "We will continue to enhance the gold content and content of the industry through digital and green transformation
