Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This NV F36 combination carrier steel rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
The unloading of Australian coal has ceased, and the quota for imported coal has been reduced. The domestic coal supply gap has gradually emerged. In the case of high inventories of power plants, there are hidden concerns about subsequent coal transfer channels. At present, there has been an increase in the number of ships that have completed the formalities of anchoring ships at Qin Port and Huanghua Port, indicating that a new round of procurement will kick off, prompting traders to continue to raise prices.

NV F36 combination carrier steel, VL E460 steel plate is a kind of structural steel plate for ship and ocean engineering. "VL" stands for the abbreviation of "DNV-GL", which is a standard jointly certified by DNV (Norway) and GL (Germany), "E" means the grade of steel plate is E, and "460" means the min. yield of VL E460 steel plate is 460 Mpa. The delivery status of VL E460 steel plate: TM (thermo mechanical control rolling), QT (quenching + tempering), TM + T (thermo mechanical control rolling + tempering).
