Affected by the global economic crisis, in 2009, China’s steel companies produced a total of 1,406,530 tons of shipboards, a decrease of 6.202 million tons from 2008, a year-on-year decrease of 30.6%. In 2009, Ansteel sold 1.82 million tons of steel plate for shipbuilding, which was 280,000 tons less than in 2008, a year-on-year decrease of 13.3%. The sales of Anshan Iron and Steel Ship Plates were relatively less affected by the financial crisis, mainly due to the relatively large domestic market share. In 2009, the domestic shipboard market share has reached 13%; and Anshan Iron & Steel’s shipbuilding plates have the most complete domestic production specifications and steel grades. The largest number and highest quality level. Since the production of the 5500mm wide and thick plate production line of the Bayuquan, the annual capacity of the Anshan Iron and Steel Group has reached 3 million tons.
Anshan Iron and Steel Co., Ltd. plate plant from the original plate factory and the original plate plant merged. At present, it is divided into two production lines, 2500mm middle plate and 4300mm thick plate.
China's first middle plate mill was built in Anshan Iron and Steel in 1936 and belongs to a three-roller mill. On December 20, 2001, in order to face the severe competition situation after joining the WTO, Anshan Iron and Steel Group Corporation approved the implementation of the technical transformation program of "three rolls and two rolls" in the original medium plate mill. On August 22, 2003, the entire trial run of the second and fourth-high rolling mills of the Anshan Iron and Steel Plant's Medium Plate Plant was successful. After a large-scale technical transformation, the medium plate mill realized the layout of a rolling mill where all three heating furnaces have achieved vaporization cooling and automatic control in the whole process. It has an internationally advanced plant and machinery and equipment, and an annual production capacity of 900,000 tons. It can produce middle plate with a thickness of 4.5mm-20mm and a width of 1450mm-2200mm. The product can be used in high pressure vessel manufacturing, shipbuilding, automobile manufacturing, metallurgy and chemical industries.
On May 25, 1993, Anshan Iron & Steel Heavy Plate Plant made a successful hot rolling test with a total investment of about RMB 1 billion. The main equipment of the wide and heavy plate plant is used equipment imported from Japan Sumitomo Metal Industry Co., Ltd. and Wakayama Heavy Plate Plant. However, after entering the 21st century, with the advancement of world shipbuilding industry and offshore platform technology, Anshan Iron & Steel 4300mm wide and heavy plate production line obviously can not meet the new needs of the market. For this purpose, the heavy plate production line has undergone technological transformation and was successfully tested on September 3, 2003. In 2007, it produced 1.11 million tons of heavy plate. The transformation was carried out in two phases. The first phase of the renovation eliminated the backward straightening machine. The new straightening machine introduced machinery and electric control equipment from Germany's largest machinery manufacturer, SMS Siemag and Siemens, with a maximum leveling force of 3,400. Tons, with advanced installed capacity in the world. The second phase of the project focused on the transformation of the rolling mill system and introduced the technology and main equipment from VAI in the UK. The new mill has a rolling force of 8,000 tons, which has the advantages of high speed and high precision. The successful completion of the heavy plate plant renovation project has enabled Angang to become a world-class high-tech shipbuilding plate production base, achieving a historic leap in its product variety structure, performance and dimensional accuracy control, and at the same time completely rewriting the heavy plate production line that cannot be produced. History of high-grade pipeline steel.
In 2006, the Angang Yingkou Bayuquan Iron and Steel Project, with an annual comprehensive steel production capacity of 5 million tons, was officially approved by the state. As a result, the world's largest wide-thick plate rolling mill will be located in the Bayuquan, with an annual production capacity of 2 million tons. The project consists of a 5500mm four-high roughing mill and a 5000mm four-high finishing mill and two step heating furnaces, a phosphorus removal tank, a hot straightening machine, three cooling beds, a head shear, and a fixed-length shear. , flame cutting machine, 4200 tons flattening machine, quenching machine, etc. more than 40 sets of supporting equipment, a total of more than 100,000 parts and components. The Angang 5m mill production line was jointly designed by China Yizhong Group and SMS-Demag, and the core equipment such as roughing mill and finishing mill was manufactured from a single weight. On July 10th, 2009, the heat load test of the rough rolling mill on the 5.5-meter-thick plate production line was successful and it entered the state of full-line production.
Anshan Iron and Steel has been developing shipboard products since 1995 and has now completed the development of ship plates from ordinary strength levels to ultra-high strength levels, achieving the goal of supplying the entire ship.
The successful adoption of the fourth shipboard expansion certification in 2006 made Anshan Steel the first company in the country and the third in the world to have the ability to produce steel plates for high-end hull structures and marine engineering structures. There are 128 steel grades certified for this ship, and the thickness specification is 8-100mm. The quality level is from the ordinary A grade to the highest quality grade F grade, and the strength grade is from 235MPa to 550MPa.
In 2008, Anshan Iron and Steel Co., Ltd. Bayuquan Iron and Steel Branch Marine Steel Billets and Shipboards passed the first certification of the Ninth National Ship Classification Society and were qualified for the production of shipboards. The certified marine steel plates include general strength grades A and B for all specifications and AH32 and AH36 ship slabs of high strength grades, and 5500 mm thick plate products with a thickness of 40 mm or less corresponding to the strength class, covering the current order quantities of shipyards. 85% or more. In the same year, Anshan Iron and Steel was the first in the country to use the TMCP process technology to produce ship plates of ultra-high strength, high strength and ordinary strength, and the technology is at the leading international level.
On April 20, 2009, Angang received official notices from the five countries' classification societies, including the United States, China, Norway, Germany, and Japan, that the company's production of large-line energy welding hulls and marine steel production platform products passed certification. The scope of products certified by these five classification societies is: Large-line energy welding hulls and marine oils with ordinary strengths A, B, D, E and high-strength AH32-EH32, AH36-EH36, and AH40-EH40. Platform steel series, the maximum thickness of the product is 100mm, welding line energy is 100kJ/cm. Its strength, low temperature toughness, specifications and other indicators have reached the international advanced level. It is much higher than the maximum thickness that can be reached by domestic steel mills is 40mm and the welding line energy is 50kJ/cm.
At present, Ansteel not only established strategic cooperation relationships with domestic ship board users such as China Shipbuilding Materials Northeast Co., Ltd., Dalian Shipbuilding Industry Group Co., Ltd., and Bohai Shipbuilding Industry Co., Ltd., but also aimed at the international market. Shipboard products continued to enter Samsung in South Korea. Daewoo, Hyundai, STX and other shipyards. In order to better serve customers, Angang Steel - Dalian Shipbuilding Heavy Industry Dalian Steel Processing and Distribution Co., Ltd. was officially established on November 25, 2004, becoming the first professional shipbuilding steel processing and distribution enterprise in China. It is expected that the steel processing volume will reach 2010 600,000 tons. Since then, they have built factories in Huludao and Qingdao, providing more favorable conditions for shipyards to use shipboards.
