On April 28, China's first heavy-duty hot-rolled H-beam production line officially started operation；
On May 27, the first batch of 1500 tons of high-strength heavy-duty H-beams were sent to the Hong Kong Special Administrative Region；
It marks that Chinese special steel companies have changed the global heavy H-beam market pattern and provided the "Chinese heavy-duty hot-rolled H-beam solution" for the high-end demand in the world's construction, railway, bridge, marine, power and other fields.
MGJT is a pioneer in the application and development of H-beam technology in China!
On July 4, 1998,MGJT built China's first hot-rolled large H-beam production line. More than 20 years later, "MGJT hot-rolled H-beam" has become a competitive and influential brand at home and abroad. The company has developed nearly 100 brands and more than 600 varieties. Hot-rolled H-beams of different specifications have filled many gaps in the high-end field of H-beams in China, and have won the National Gold Medal Award for Metallurgical Science and Technology, the Second Prize of National Science and Technology, and the products have passed Japan JQA, EU CE, Russia GOST, Singapore BC1, South Korea KS, Malaysia SIRIM and other global certifications.
Products have been exported to more than 50 countries and regions around the world
In the process of integration into global development, MGJT has limited its own H-beam technology and equipment, and is difficult to participate in the competition of heavy H-steel required for some key projects at home and abroad. The heavy-duty H-shaped production line with comparable technology is committed to creating the first domestic full-spec H-beam production enterprise, and promotes the application and development of domestic heavy-duty H-beam.
On January 18, 2020, MGJT's heavy-duty H-beam production line completed the thermal load test at one time.
Since March 29, Maanshan Iron & Steel has developed three American standard heavy-duty H-beams, all of which have met design standards and are ready for production.
MGJT's heavy-duty H-beam production line is designed to have an annual production capacity of 800,000 tons, with product height, width, and flange thickness up to 1108mm, 476mm, and 115mm, respectively.
Using the world's advanced near-net shape blank casting, full protection casting, hydraulic AGC, dynamic axial adjustment DAA, small tension control, ultra-fast cooling after rolling, etc., can effectively improve the cleanliness of the molten steel, product appearance size and Dimensional control accuracy and product flatness.
The production line focuses on high value-added H-beam products such as heavy-duty, thick-walled and wide-flange series that cannot be produced in China at present, and partially supplements extra-large-size angle steel, U-shaped steel sheet piles, hat-shaped steel for railway vehicles and other special-shaped steel products. Japanese standard, American standard, British standard, European standard and national standard organization production.
