the first continuous casting and direct rolling production line in Baowu, China was born
On August 16, with the rumble of the rolling mill, the green and low-carbon direct rolling technical transformation project of Honggang high line of Kunming Iron and Steel Co
, Ltd
was officially put into operation, marking the birth of the first continuous casting and direct rolling production line in Baowu, China
The project can reduce the process energy consumption by 10
62kg standard coal / ton, reduce the carbon dioxide emission by 71200 tons per year, and the process carbon reduction rate is more than 46%, which is also China Baowu removal & ldquo; Looper & rdquo;, A vivid practical case of promoting green and low-carbon development through process route adjustment

Why remove & ldquo; Looper & rdquo;
In the connection between steelmaking and rolling, in order to solve the mismatch of casting and rolling rhythm, a heating furnace is set as & ldquo; Looper & rdquo;, The purpose of solving the problem of off-line billet and low-temperature billet is to heat the billet to a uniform temperature suitable for rolling
But the middle one & ldquo; Looper & rdquo; The existence of also brings about the improvement of cost, the reduction of efficiency and the increase of carbon emission
To this end, Chen Derong, Secretary of the Party committee and chairman of Baowu, China, stressed that the removal of & ldquo; Looper & rdquo;, Promoting green and low-carbon development with extreme efficiency is not only related to the future competitiveness of enterprises, but also related to the good life of each of us
Remove all & ldquo; Looper & rdquo Technology and management progress to achieve the ultimate efficiency improvement should be the direction of our efforts

Continuous casting and direct rolling technology
Continuous casting and direct rolling refers to the technology application encouraged by the national catalogue for the guidance of industrial structure adjustment (2019 version), which directly enters the rolling line to roll finished products without heating furnace after continuous casting
Zhongnan iron and steel responded positively and acted quickly, implemented the relevant requirements of the group company, communicated with the most powerful design institutes in China, fully understood the application examples of continuous casting and direct rolling technology in iron and steel enterprises at home and abroad, and comprehensively evaluated 32 steel rolling lines belonging to Songshan, Echeng Iron and steel, Chongqing Iron and steel and Kunming Iron and steel, 12 conditions for continuous casting and direct rolling are sorted out
After investigation and discussion, in terms of electric induction heating and gas heating, one rod and one line are selected for the first test, and the two major projects of Kunming Iron and steel red steel high line and Chongqing Iron and steel double high rod are formulated to take the lead in realizing the goal of continuous casting and direct rolling within this year

After Kunming Iron and steel company joined China Baowu family, Zhongnan iron and steel implemented the requirements of the group company in the collaborative support of Kunming Iron and steel company, deeply tapped the carbon reduction potential, and proposed to cancel the steel rolling process & ldquo; Looper & rdquo The idea of realizing continuous casting and direct rolling has been highly recognized and actively promoted by Kunming Iron and Steel Co
, Ltd
, and it is determined to quickly carry out continuous casting and direct rolling technical transformation with Honggang high-speed wire rod as the pilot
At the same time, technical personnel were organized to conduct field visits to relevant domestic enterprises

Under the overall layout and technical support of Zhongnan iron and steel, the concern and support of the long material Committee of the group company and the attention and promotion of Kunming Iron and steel company and Honggang base, in May this year, the project design and contract signing of the green low-carbon direct rolling technical transformation project of Honggang high line were completed, and the construction was started in June, which was officially put into operation in only 74 days
The project cancels the heating furnace & ldquo; Looper & rdquo;, Using electric heat supplement technology for on-line heat supplement and using the transverse conveying chain to send the continuous casting billet to the rolling mill for direct rolling can effectively reduce the heating proportion of gas, and achieve remarkable results in reducing cost, improving efficiency, energy conservation and emission reduction

It is reported that Chongqing Iron and steel double high bar continuous casting and direct rolling project is also about to be completed and put into operation
In the next step, Zhongnan iron and Steel Co
, Ltd
and Kunming Iron and Steel Co
, Ltd
will resolutely implement the requirements and & ldquo; Double carbon & rdquo; According to the deployment of work, carefully summarize practical experience, continue to promote the application of continuous casting and direct rolling technology, formulate targeted process and technical routes according to the principles of minimum cost, optimal benefit, minimum energy consumption and maximum carbon reduction, combined with the actual layout of casting and rolling interface of each base, carry out transformation according to local conditions, and complete 100% continuous casting and direct rolling of conditional steel rolling lines in recent years, At the same time, comprehensively promote & ldquo; 6C” Reduce carbon from & ldquo; Plan carbon reduction, process carbon reduction, technology carbon reduction, efficiency carbon reduction, chain carbon reduction and green carbon reduction & rdquo; Develop a carbon neutralization roadmap in six aspects to help achieve the carbon neutralization goal of China Baowu carbon peak
