Wuhan Iron and Steel Co., Ltd. Cold rolling mill to build a first-class production line of high-Al-Zn-Al-mg pickling steel.

On the eve of July 1st, the commendation meeting of the key technical transformation project for the 100th anniversary of the founding of the Party in the cold rolling mill of WISCO was held in front of the original five-stand rolling mill of the 1700 project. commending 101pickling steel production line, 108high aluminum zinc aluminum magnesium production line to achieve production, 273amp 274 plate to coil production line to achieve "Sida". These key production lines are put into production and reach production, indicating that Castle Peak Cold Rolling will have a better product structure and stronger profitability. This is also the answer that cold rolling is rapidly moving forward in the direction of high-quality development of "efficiency and efficiency", constantly optimizing the variety and structure of products, creating new profit growth points, and handing over the answer to the Party's centenary with the practical action of overcoming difficulties.

101 pickling steel production line

The 101pickling steel production line adopts advanced laser welding and continuous shallow groove turbulence technology, which can realize the batch supply of high-strength, thin specification and low-cost pickling varieties after technical transformation, and the thinnest 1.2mm short process high-strength pickling steel fills the gap in Baosteel's green cost manufacturing technology of "replacing cold with acid" and provides a strong support for the company to achieve the goal of "carbon peak and carbon neutralization".

108 high-Al-Zn-Al-mg production line adopts horizontal furnace annealing process, equipped with pre-melting pot equipment, using zinc-aluminum-magnesium coating and other patented technology to create a low-carbon process to produce environmentally friendly and high corrosion-resistant color coating substrate, which fills the gap in this field of Castle Peak Base.

273 change 274 board to roll production line

The 273x274 plate rewinding production line has achieved a breakthrough in key processes such as sectional tension control and vertical inspection for the first time in Qingshan base, which is the widest and best rewinding inspection unit in China, and plays a decisive role in breaking through the logistics bottleneck of Qingshan cold rolled automobile plate manufacturing.

The cold rolling mill has a high degree of coordination with the participating units, overcomes various adverse effects caused by difficulties in construction organization, process debugging and many interfaces of the old production line, and scientifically formulates a "four horizontal and four vertical" management system to meet the difficulties. in the spirit of advanced planning, pragmatic hard work and continuous struggle, we stick to the technical renovation site, solve the difficulties in technology, equipment and construction, and achieve the goal of "ensuring safety, quality and time limit". 101pickling steel production line was completed four months ahead of schedule, and the production speed of 108high-aluminum-zinc-aluminum-magnesium production line was the best of the same kind of hot-dip galvanizing unit. Within three months of putting into production, mass production of 1000 surface grade automobile outer plate was realized and "Sida" was successfully realized.

In recent years, the cold rolling mill of WISCO has been committed to doing better and stronger cold rolling, and the demand for technical transformation is increasing day by day. With the implementation of key technical transformation projects such as 1700 unit acid regeneration and environmental protection transformation, new color coating unit construction, cold rolling collection center construction and so on, cold rolling will create a "green, intelligent and efficient" international first-class production line. The meeting put forward three requirements for the next step of technological reform:

First, we should take the construction of the "double excellent project" as the goal, constantly improve the management ability of the technical transformation project, and train and train more excellent project leaders and project management teams through project management.

Second, we should dare to create a "cold rolling speed" for technological transformation and construction, and all projects should be completed and put into operation in strict accordance with the established nodes, and strive to achieve the "double improvement" goal of putting into production ahead of schedule and reaching the fourth level through the improvement of management capacity, and seek benefits from efficiency.

Third, based on the six-year development plan of cold rolling, priority should be given to the construction of projects to improve operational efficiency, optimize product structure and improve product quality, so as to promote the continuous deepening and implementation of cold rolling planning.

The meeting called on that this year marks the 100th anniversary of the founding of the Communist Party of China, and we should take the party's 100-year course as an inspiration, show the passion of "striving for the first class in everything," stimulate the spirit of "not waiting for the whip to work hard," forge ahead, work tenaciously, complete various tasks of technological transformation and construction in an all-round way, and work hard for the construction of the best cold rolling mill!
