Hot rolled steel coil

1. Introduction
The head and tail of the straight hair curler are often tongue-shaped and fish-tail-shaped, with poor thickness and width accuracy, and the edges often have defects such as wave shape, folded edge, and tower shape. Its roll weight is heavier. (Generally the pipe industry likes to use it.)
2. Use
Hot-rolled products have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as steel, construction, machinery, boilers, and pressure vessels.
Application range:
(1) After annealing, it is processed into ordinary cold rolling;
(2) The galvanizing unit with pre-annealing treatment device processes galvanizing;
(3) Panels that basically do not need to be processed.
3. Classification
Common carbon plate, excellent carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, container plate, etc. Hard-rolled coils: Continuously rolling hot-rolled pickled coils at room temperature.
Hot continuous rolled steel sheet products include steel strips (coils) and steel sheets cut from them. The steel strip (roll) can be divided into straight hair rolls and finishing rolls (divided rolls, flat rolls and slitting rolls)
