SMM News: "nearly 1/8 of the steel of the Hong Kong-Zhuhai-Macao Bridge comes from Liugang, the Bird's Nest, the three Gorges and many other super projects have used Liugang steel." Gan Guiping, general manager of Guangxi Liuzhou Iron and Steel Group (hereinafter referred to as "Liugang"), said.
Last year, Liugang became the first state-owned enterprise in Guangxi to make more than 10 billion annual profits. From the beginning of the establishment of the local small enterprises, grew into the world's top 50 iron and steel enterprises, China's iron and steel "first square" enterprises, and coruscated vitality in the new era. How did the largest iron and steel enterprise in southwest China realize the "green" transformation in the new era?
"behind the report card is the continuous strengthening and deepening of the transformation of Liugang." Pan Shiqing, chairman of Liugang Group, said.
In recent years, under the positive factors such as the continuous promotion of supply-side structural reform in China and the complete ban on "ground steel", Liugang has seized the opportunity, optimized the production organization mode, innovated and upgraded the product grade, and released the superior production capacity at full capacity. The production and management efficiency of the enterprise has been significantly improved, reaching the best level in history.
"Liugang has the unique advantage that the rolling capacity is far greater than the steelmaking capacity in the industry, which enables Liugang to flexibly adjust production according to market demand, what production, to minimize the production period and delivery cycle, to avoid ineffective supply." Gan Guiping said that in recent years, the production and marketing rates of Liugang have been maintained at more than 100 percent.

"in the past, the added value of Liugang products was low, and the proportion of high-grade products was on the low side." Gan Guiping said that Liugang has actively promoted the upgrading of its products. Now, on average, more than 10 new products are developed each year, with more than 500 kinds of products, which are widely used in automotive, petrochemical, machinery manufacturing and other industries.
"last year, Liugang took over Guangxi Iron and Steel Group, led the construction of Fangchenggang Iron and Steel Base, acquired and reorganized a stainless steel company, forming a new territory of 'one body and two wings'." 'The next step is that the size of Liugang will double, and the company's output value, profits and taxes will be greatly increased, 'Mr. gan said.
Into the Fangchenggang iron and steel base, a hot construction scene, hundreds of tower cranes, dynamic tamping machines and other types of machinery all open. Li Meiliang, deputy general manager of the company, said that they have built a 200,000-ton wharf connected to the railway, overseas raw materials directly to the factory by sea, and the products can be shipped to the whole country by railway and waterway.
"in addition to speeding up the layout of the new territory, Liugang has accelerated scientific and technological innovation to promote factory automation and information construction." Gan Guiping told reporters.
In the cold rolling mill of Liugang, with the issuance of electronic instructions from the staff in the operation room, two unmanned crane began to work. "Unmanned crane has a number of fully independent intellectual property rights, and has become an important part of the construction of the cold rolling mill's' wisdom factory 'since it was put into use last year." Wu Chunping, director of the cold rolling mill, said.

The reporter saw in the cold rolling mill that the whole process of steel coil was transferred intelligently among the working procedures, and the coil information was automatically identified. High-intensity work, which used to require four workers, can now be done with only two people in the operating room. Wu Chunping said that intelligence has improved efficiency, reduced the labor intensity of workers, and improved the accuracy of work.
Walking in the Liugang plant area, the intelligent production line runs in an orderly manner, the environment in the factory area is clean and tidy, the green trees on both sides of the road are lush, and there is no dust on the roads of the factory area, which is hard to associate with. In the past, dust was everywhere and yellow smoke was everywhere.
In the 1980s and 1990s, Liugang, wearing the hat of high energy consumption and heavy pollution, triggered a debate about whether to want Liuzhou or Liugang. "at that time, many production posts were dirty and black, and it was difficult for workers to have a clean place on their clothes. Bicycles were easy to rust outside." Liu Gang Group Operations improvement Department Minister Gao Yunying recalled.

"Liu Gang firmly believes that 'not doing a good job in environmental protection does not even have the right to survive,' so we will further promote energy conservation and emission reduction and develop circular economy." Gan Guiping said that Liugang has invested nearly 8 billion yuan in the comprehensive treatment of the "three wastes," built more than 8 billion sets of energy conservation and emission reduction facilities, and the annual environmental protection operating cost exceeds 1.7 billion yuan, and green development has become a new driving force for the development of enterprises.
As a ten-million-ton steel enterprise, slag and steel slag produced in the production process of Liugang not only do not cause solid waste pollution, but also become valuable resources. The reporter saw in the slag vertical grinding production line of Liuzhou Qiangshi Technology Co., Ltd., slag and waste slag through vertical mill grinding treatment, transformed into fine powder. Zhou Yongxin, deputy manager of the company, said that slag powder can be widely used in concrete and some cement production, the preparation of high-grade, high-performance concrete, has become a popular green building materials in the market.
Since 2010, Qiangshi Company, as a subsidiary of Liugang, has converted 15.3 million tons of waste residue into slag powder products, solving the problem that tens of millions of tons of industrial solid waste has nowhere to be stacked. "thanks to the circular economy, the total assets of the company have reached 750 million yuan, and the supply of products exceeds demand," Zhou said. "
