Description
EN10025 2004 S355J0 Hot Roll Steel plate
Hot Roll Steel plate
Continuous casting or blooming slabs are used as raw materials, heated by a walking beam heating furnace, descaled by high-pressure water, and then enter the roughing mill. The roughing material is cut, tailed, and then enters the finishing mill for computer-controlled rolling. After the final rolling, it is cooled by laminar flow (computer-controlled cooling rate) and coiled by a coiler to form a direct coil. The head and tail of straight hair curls are often tongue shaped or fish tailed, with poor accuracy in thickness and width. There are often defects such as wave shaped, folded edges, and tower shaped edges. Its coil weight is relatively heavy, and the inner diameter of the steel coil is 760mm.
1、 Introduction to S355J0 steel plate:
S355J0 steel plate is mainly used in bridges, ships, power station equipment, lifting and transportation machinery, mechanical manufacturing, and other engineering and welding structural components that bear high loads.
