Hot Rolled Steel Coil
Product Description
Hot Rolled Steel coil is made of continuous casting slab or blooming slab as raw material, heated by walking beam furnace, descaled by high pressure water, and then sent to roughing mill. The roughing material is cut, tail, and then sent to finishing mill for computer controlled rolling. After finishing rolling, it is directly sent into coils after laminar cooling (computer controlled cooling rate) and coiler coiling.
High Performance
Hot Rolled Steel Coil and Hot Rolled Sheet have excellent properties such as high strength, good toughness, easy processing and good weld ability, so they are widely used in manufacturing industries such as steel, construction, machinery, boilers, and pressure vessels.
High Quality
Best raw materials for production advanced technologies and thorough inspection system.
