Jigang was founded in 1958. It is an early local backbone steel enterprise in China and a largest production base for medium and thick plates in the country.

In March 2008, Shandong Iron and Steel Group Co., Ltd. was established, and Jigang became the main member of Shan Steel Group. On August 31, 2016, in order to deepen supply-side structural reform and implement the national capacity reduction policy, the Shandong Provincial Government studied and passed the "Overall Plan for the Adjustment of Ji Steel Production Capacity and the Transformation and Development of Shandong Steel". In accordance with the requirements of the plan, Jigang Group safely shut down 6.5 million tons of production capacity and smoothly divert nearly 20,000 employees from June 29 to July 31, 2017 in just 33 days. From the construction of the factory in 1958 to the suspension of production of the steel production line, a total of 155 million tons of iron, 155 million tons of steel, and 137 million tons of steel were produced in 59 years; profits and taxes were achieved of 31.6 billion yuan.

After the main steel business was suspended, Jigang, with the care and support of superior party and government organizations, firmly established the concept of "de-capacity reduction is not about de-enterprise, but accelerating the transformation of new and old kinetic energy is the key" and in accordance with the goal of "second entrepreneurship and reshaping Jigang" Positioning, firmly seize the favorable opportunity of the province and city to implement major projects for the transformation of new and old kinetic energy, actively explore new development models of "industry-city integration", from "relying on steel to make a living" to "develop without steel", it takes four years to make a breakthrough A new way to transform the new and old kinetic energy of traditional enterprises has been gradually formed, and a green and sustainable development industrial structure supported by existing industries, new industries and future industries has been transformed from an emission-oriented enterprise to a consumption-oriented enterprise, realizing nirvana Rebirth.

In the future, Jigang will keep in mind the mission of state-owned enterprises, continue to maintain the general tone of work of seeking progress while maintaining stability, fully, accurately and comprehensively implement the new development concept, deeply connect with major national strategies of the Yellow River, major projects for the transformation of new and old kinetic energy in provinces and cities, and integrate into urban development. , serve the local economy, take "high-end, green, intelligent, branded, and international" as the strategic implementation path, and strive to build a new steel industry ecosystem with independent and controllable core technologies, safe and efficient industrial chain, and smooth industrial ecology The system, strives to create a "three-transformation" benchmark for the transformation of R&D results, transformation of new and old kinetic energy, and transformation of traditional enterprises in the province, and make it solid, do it well and improve the "test field for the transformation of new and old kinetic energy" in the province and city, with excellent development achievements, In the process of promoting high-quality development of provinces and cities, demonstrate the responsibility of state-owned enterprises and contribute the "Jirin Power"!
