Hot Rolling Quality Promotion Ten Years
Tenth Anniversary Record of 2300 Production Line of Hot Strip Mill
Ten years, in the long course of history, is only a moment in a hurry. However, for the hot rollers of Benxi Iron and Steel Co., which have entered a new era, the development of 2300 production line in the past ten years is based on the expectations of too many people and condenses the painstaking efforts of too many people.
December 1, 2008, is a special day that will be forever recorded in the history of Benxi Iron and Steel Company. The 2300 production line of the world's first widest hot strip mill has been built and put into operation in Benxi Iron and Steel Company. Since then, the blueprint for the construction of a 100-year high-quality multi-tonnage high-quality plate base in Benxi Iron and Steel has gradually become a reality, so that Benxi Iron and Steel has a "fulcrum" of development standing in the world since then.
On November 28, 2018, at 2236 hours, a cheer from the operation room of 2300 production line broke the silence for a long time. Daily production of 18798 tons on the 28th day is the highest record since the establishment of the production line.
Ten years of progress, from soft steel to hard steel, from plain steel to high value-added products, from general specifications to limit specifications, today's hot strip mill, the implementation of the "quality strategy" policy, in the high-end market to highlight the "strength card", so that the hot rolling products of Benxi Iron and Steel become a world-famous brand dream, is being realized step by step.
Target Clear, Build China Hot Rolling "Flag" Production Line
In the early stage of construction, 2300 production line created a miracle in the history of similar engineering construction: 15 kinds of steel and more than 30 specifications of coils were rolled out in half a month after commissioning. Foreign experts participating in equipment debugging have repeatedly expressed their sighs and admiration that so many special steels with high technical content and high difficulty coefficient have been rolled in such a short period of time, which has turned the "impossible" in the industry into reality. During the commissioning period of 2300 production line, 56 steel grades and 610 specifications were successfully rolled, making it the shortest time to put into operation for the same type of units in the same industry in China and the most specifications for rolling products.
In the initial stage of production, the cadres and workers of 2300 production line in all regions carried forward the spirit of striving for the first-class hot rolling. They were united, practical, daring to try and break new production records, and achieved a high starting point. In October 2011, monthly output exceeded the 440,000-ton mark, setting a record of 445,733,000 tons; on February 29, 2012, daily output reached a record of 18,035 tons, and on April 21, the same year, shift output reached a record of 7,115 tons. In the past 10 years, 2300 production lines have rolled 43.1 million tons of coils, accounting for 1/2 of the total output of hot strip mills.
Today, the glorious and heavy certificates on the honor list of enterprises witness the extraordinary road that 2300 production lines have gone through for ten years: in 2011, hot rolled steel sheets and strips for automotive structure BG330CL, BG380CL and BG420CL won the China Metallurgical Products Excellent Quality Award and the Gold Cup Award for Metallurgical Industry; in 2013, hot rolled steel sheets and strips for cold forming. In 2014 and 2017, hot rolled steel sheets and strips for automotive structure BG380CL and BG420CL won the China Metallurgical Products Excellent Quality Award and Metallurgical Industry Gold Cup Award.
Starting from a high starting point and building up a strong sense of quality first
Since the day of commissioning, the 2300 production line, which has been shouldering the development mission of Benxi Iron and Steel for one hundred years, has assumed the responsibility of rolling high-end hot-demand products in the market and establishing a new image of Benxi Iron and Steel products in accordance with market demand. In recent years, with the deepening of enterprise reform, no matter the three hot rolling lines in the form of branch plants or 2300 production lines in the operation area, they have actively adapted to the changing market situation, constantly optimized product structure, constantly upgraded product grades, and developed towards the direction of exceptional, precise and high level. Consensus has been formed in all regions of 2300 production lines. 。
Beginning in 2012, 2300 production line has reformed the laminar cooling device, updated the flying shear, and laid a solid foundation for improving equipment accuracy and expanding varieties and specifications. In order to ensure the stable rolling of high value-added products, the "Guidance for Production Technology of Automobile Plate" was issued. The products are also gradually developing from the wheel series and container series to the oil pipeline, pickling board and automobile plate. From soft steel to hard steel, from ordinary steel to high value-added products, from general specifications to limit specifications, while smoothly producing limit specifications products, 2300 production line overcame industry difficulties at one stroke, successfully independently developed and mass produced X80 high-grade oil pipeline steel and passed the quality inspection of PetroChina, filling in Benxi Iron and Steel products. The blank has created the production record of the shortest production time and the shortest R&D time in the same industry in China. In the same period, the 2300 production line successfully rolled X100 pipeline steel and produced high-grade ship plate steel.
In the past ten years, the proportion of "double high" products and the physical quality of products in the 2300 production lines have been greatly improved. The production of new products has achieved remarkable results, and the volume of export volumes has been ahead of the industry. The stable performance of products has made the products of hot rolled steel continuously enter the world. Automobile panels manufactured by enterprises are exported to Italy, India, South Korea and other international enterprises for high-end accessories. The dream of "making Benxi Iron and Steel Hot Rolled Products a world famous brand" is being realized step by step.
In 2018, every area of 2300 production line has made greater and faster strides toward excellence: the first trial production of high-strength pickling plate B540HE has been successfully rolled, making the high-strength pickling plate series of Benxi Iron and Steel reach more than 20 brands after adding new members. The "FAW-Volkswagen DY Model Certification Material" which challenges the "high-end automobile panel" and the "Dawning Mercedes-Benz Heavy Card" for the first time are of great significance for Benxi Iron and Steel to occupy the automobile panel market. Up to now, the 2300 production line has successfully rolled 559 steel grades and more than 7000 specifications, producing 34.5 million tons of high value-added products.
