What is the RD 32 VSL vessel steel sheets application

Shipbuilding steel plates are used to manufacture the hull of marine and inland ships. High strength, plasticity, toughness, cold bending performance, welding performance and corrosion resistance are required for shipbuilding steel plates. Boiler steel plates are used to manufacture various boilers and important accessories. As the boiler steel plate works under medium temperature (below 350℃) and high pressure, it is also subject to impact, fatigue load and water and gas corrosion. The RD 32 VSL vessel steel sheets, boiler steel plate is required to ensure a certain strength and have good welding and cold bending properties.

Consumption of RD 32 VSL vessel steel sheets, finished steel products in Latin America in 2019 was 64.2 million tons, down by 5% compared to 67.6 million tons in 2018. The decline in steel consumption in the region reflects the contraction of Latin American economies, particularly the three major economies: Mexico, Argentina and Brazil. These three countries together accounted for 87% of the reduced steel consumption in Latin America. However, our steel materials export volume to those countries did not decrease but show a increasing tendency last year.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This RD 32 VSL vessel steel sheets production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate RD 32 VSL vessel steel sheets size.

Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the RD 32 VSL vessel steel sheets, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.
