Lianqiang Roller, the company was formerly a joint construction enterprise of the General Institute of Iron and Steel Research of the Ministry of Metallurgy and Fengnan County. It was founded in the early 1970s. It is one of the earliest professional metallurgical roll manufacturers in China that developed centrifugal roll technology and engaged in centrifugal casting. For more than 40 years, it has occupied the forefront of China's small and medium-sized centrifugal rolling industry. Its customers are spread across more than 20 countries and regions around the world and enjoys a reputation in the global steel industry!

Lianqiang Roller was laid in the Liucheng Economic Development Zone, Chaoyang County, Chaoyang City, Liaoning Province in June 2019, and launched a new production base construction project. The construction goal is to build a roll production base with world influence. The project covers a total area of ​​105 mu, with an investment of 630 million yuan. Its main business is to produce and sell more than 30 types of rolling products such as centrifugal casting and conventional casting, such as cast iron rolls, high-speed steel rolls, composite cast steel rolls, etc., all of which can be completed and put into production for annual production. 50,000 tons of production.

At present, the first phase of the Lianqiang Rolling Rolling Project was successfully completed in November 2021, achieving full production process and an annual production capacity of 25,000 tons of rolls. At the same time, it has achieved outstanding achievements in national high-tech enterprises, innovative small and medium-sized enterprises in Liaoning Province, above-scale enterprises, outstanding growth industrial enterprises, Liaoning Province Chiying Enterprises, Liaoning Province Substantive Industry-university-Research Alliance Platform, Chaoyang City Enterprise Technology Center, and China's Steel Industry Supplier, a green benchmark enterprise in China's steel industry, a member unit of the Liaoning Provincial Enterprise Federation, and many other honors.

In order to adapt to the needs of social development, meet customers' increasing product and technical service needs, and enhance the company's market competitiveness, Lianqiang Roller will focus on "creating a new green digital manufacturing benchmark for customers, the future and the world!" The development vision will adopt the four-step upgrade policy, namely equipment mechanization, equipment automation, manufacturing informatization, and operation digitalization. We will be committed to the research and development of core technologies and upgrade traditional production equipment as the company's strategic goal for the next three years.

Therefore, while simultaneously promoting the construction of the second phase project, Lianqiang Roller actively carried out various equipment upgrades, through independent research and development and cooperation with professional manufacturers, Lianqiang automatic casting system, automatic batching system, end cover molding production line project, heat treatment Equipment upgrade work such as spray quenching machine project has been implemented one after another, and remarkable results have been achieved. At the same time, in terms of digital upgrades and transformation, after research and development and design by Lianqiang MES project team, Lianqiang Rolling MES project (Phase I Project) was officially completed and launched on December 15, 2023. It is the earliest rolling roller in the industry to use the MES system. Enterprise, Lianqiang Roller has completely broken the production model inherent in the traditional rolling industry. It provides strong support in production management, quality control, supply chain coordination, etc., so that Lianqiang rolling rolls not only achieve vertical connection from production process to automation equipment, but also achieve horizontal connection, innovative informatization and The integrated production model of industrial automation has greatly strengthened the production efficiency and per capita labor efficiency of Lianqiang rolls, not only improving the competitiveness of Lianqiang rolls itself, but also setting a new technical benchmark for the entire rolling industry.

At this stage, Lianqiang Roller is collaborating with outstanding universities and professional material research and development teams such as Beijing University of Science and Technology, Beijing University of Technology, and Hebei University of Technology. Through the continuous advancement of powder metallurgy projects and robot intelligent manufacturing system projects, we actively strengthen our own technology. Level and equipment ability. In the future, Lianqiang Roller will use a production method that combines data management systems and intelligent production equipment to build Lianqiang Roller into a new digital intelligent factory for customized, digital and automated production management, and become a benchmark enterprise guiding the development of the world rolling industry. .
