It was learned from Anshan Iron and Steel that Anshan Iron and Steel Co., Ltd. won the world's widest contract sheet for Q345R pressure vessel steel plate
, which will supply chrome-molybdenum steel for core pipeline of more than 3,000 tons of reforming unit for the largest refining and chemical integration project in China, further boosting domestic petrochemicals. Industrial equipment development.
The pipeline design diameter of the project is 1622 mm. It is the first time in China to adopt the single-stitch direct welding process. It requires an ultra-wide specification pressure vessel steel plate of more than 5 meters. The widest width of the product is 5030 mm, the width of the raw edge product is 5200 mm, and the width specification is the current world. The most. This width-specific Q345R pressure vessel steel plate can only be produced in Angang.
In November 2017, the project side and Angang Steel conducted in-depth communication. Angang was “tailor-made” for the users and relied on the advanced process equipment and deep technical accumulation of the 5500 mm wide plate production line to challenge the limit, break the routine and solve the 5 meters. The above-mentioned ultra-wide pressure vessel chrome-molybdenum steel plate rolling, straightening, heat treatment and other production and technical problems, developed a unique control rolling and heat treatment process. The steel plate produced by Anshan Iron and Steel Co., Ltd. has good shape and stable performance, which lays a good foundation for the construction of Q345R pressure vessel steel plate project.
