JIS G3101 Hot Rolled Coils for construction
Brand : Sincere
Product origin : Tianjin, China
Delivery time : 7days-25days
Supply capacity : 50000tons per month
Hot rolling coil is made of continuous casting or primary rolling slab as raw material, heated by stepping heating furnace, descaled by high pressure water into the rough rolling mill, rough rolling material after cutting head, tail, and then into the finishing mill, the computer control rolling, after the final rolling is laminar cooling (computer control cooling rate) and coiler coiling, become straight coil.
Hot rolled products have high strength, good toughness, easy processing and good weldability and other excellent properties, so they are widely used in construction, machinery, boiler, pressure vessel and other manufacturing industries.
Application scope:
(1) After annealing, it is processed into ordinary cold rolling;
(2) Galvanizing unit with annealing pre-treatment device processes galvanizing;
(3) Basically do not need to process the panel.
The continuous casting slab or primary rolled slab is used as raw material, heated by stepping heating furnace, descaled by high pressure water and then entered the roughing mill. The roughing material enters the finishing mill after cutting head and tail, and then carried out computer controlled rolling. After the final rolling, it goes through laminar cooling (computer controlled cooling rate) and coiler to become straight hair coil. The head and tail of straight hair coil are often tongue and fishtail, and the accuracy of thickness and width is poor. The side part often has defects such as wave shape, folding edge and tower shape. The coil is heavy and the inner diameter of the steel coil is 760mm.
Hot rolled plate strength is relatively low, surface quality almost (oxidation, low finish), but good plasticity, generally medium thick plate, cold rolled plate: high strength, high hardness, high surface finish, generally thin plate, can be used as stamping plate.
Hot rolled steel plate, mechanical properties are far inferior to cold processing, also inferior to forging processing, but has better toughness and ductility
width: 20mm-1500mm
thickness: 0.7 -above
surface: black color
usually have stocks, it is depends on the sizes you need.
