Hot-Rolled Coil

Hot - rolled coils use continuous - casting slabs or blooming slabs as raw materials. After being heated in a walking - beam furnace and having the scale removed by high - pressure water, they enter the roughing mill. The roughly - rolled materials, after having their heads and tails cut off, enter the finishing mill again, where computer - controlled rolling is carried out. After the final rolling, they immediately go through laminar - flow cooling (the cooling rate is computer - controlled) and are coiled by a coiler, becoming directly - dispatched coils.

PRODUCT OVERVIEW

Overview

Hot - rolled coil takes continuous casting slab or blooming slab as raw materials. After being heated in a walking - beam heating furnace and descaled by high - pressure water, it enters the roughing mill. The roughly - rolled material, after having its head and tail cut off, enters the finishing mill again, where computer - controlled rolling is carried out. After the final rolling, it immediately undergoes laminar - flow cooling (the cooling rate is computer - controlled) and is coiled by a coiler, becoming a directly - dispatched coil.

technical parameters

Parameter

The executive standards for hot - rolled coils include GB/T 3274 - 2007 "Hot - rolled Thick Steel Plates and Steel Strips for Carbon Structural Steels and Low - alloy Structural Steels" and JIS G 3101 - 2010 "Rolled Steels for General Structure". These standards stipulate the quality requirements for hot - rolled coils, including but not limited to the chemical composition, mechanical properties, and dimensional tolerances of the materials. For example, the standard products can be Q235B in line with GB/T 3274 - 2007 or SS400 in line with JIS G 3101 - 2010. These standards ensure the quality and performance of hot - rolled coils, meeting the needs of different industries and applications.
