Relying on the "Collaborative Innovation Center of Steel Common Technology", the "High-strength Thin Steel Plate Heat Treatment Line Transformation Project" cooperated by Northeastern University and Angang (000898) Co.
, Ltd.
has successfully mass-produced a series of S32101 ultra-wide Fufu duplex stainless steel
with a thickness of 8~40mm and a width of 1500~3700mm.
The steel plate has stable performance and good
plate shape.
The mass production of this product is not only an affirmation of Northeastern University's "key equipment technology for heat treatment of large-scale high-performance special steel plate", but also a major breakthrough in the localization and autonomy of China's third-generation nuclear power key equipment materials, filling the gap
at home and abroad in terms of width.
The "High-strength Thin Steel Plate Heat Treatment Line Transformation Project" was launched in February 2016, and Northeastern University undertook the development, supply and commissioning of high-temperature roller-bottom heat treatment furnace, multi-function roller quenching machine complete sets of equipment and full-line control systems
.
In order to ensure the supply of ultra-wide steel plate for the manufacture of a key domestic engineering equipment, through the joint efforts of the project team members and scientific arrangement, it took 5.
5 months to complete the design, manufacture, installation and oven, and began the heat load test, and the solution treatment
of the ultra-wide duplex stainless steel plate with a maximum width of 3700mm and a thickness of 14mm has been realized.
Because of its excellent corrosion resistance, fatigue life, yield strength and economy, S32101 is widely used in equipment and structure construction
in moderately corrosive environments such as third-generation nuclear power plants.
However, because of this kind of steel, the plasticity is poor, the processing is difficult, and the requirements for heat treatment equipment and process control technology are also extremely high
.
High-temperature roller-bottom heat treatment furnaces and roller quenching machines are key equipment
for heat treatment production.
The equipment technology developed by Northeastern University for this project can realize the production of high-quality heat treatment equipment for high-end steel plate products such as ultra-wide special stainless steel and nickel-based alloy with a maximum width of 4000mm (MAX.
1200°C), high heating accuracy (±5°C), high surface quality and high flatness, and solves the problem of
high-quality heat treatment equipment for ultra-wide special stainless steel, nickel-based alloy and other high-end steel plate products.
