09CuPTiRE-B steel density production in steel mills tightened

Q345qCNH grade is a weather-resistant structural steel for bridges. Bridge steel grade is Q345qC. It is produced by the standard GB / T714-2014. Weather-resistant bridge plate Q345qCNH is a kind of structural steel plate for bridge. Add a certain amount of alloy elements, such as P, Cr, Ni, Cu, Mo, etc. to the steel to form a protective layer on the surface of the metal substrate to improve the atmospheric resistance corrosive steel.

Specification range of available steel 09CuPTiRE-B steel density: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates 09CuPTiRE-B steel density can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the 09CuPTiRE-B steel density steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.

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 09CuPTiRE-B steel density 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 09CuPTiRE-B steel density size.
