Product Description

                                         HOT ROLLED STEEL COIL

Hot rolling (hot rolling) is relative to cold rolling, cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature. To put it simply, a billet is heated and rolled several times, then trimmed and straightened into a steel plate. This is called hot rolling. Can significantly reduce energy consumption and reduce costs. The metal has high plasticity and low deformation resistance during hot rolling, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the processing performance of metals and alloys, that is, the coarse grains in the casting state are broken, the cracks are significantly healed, the casting defects are reduced or eliminated, the as-cast structure is transformed into a deformed structure, and the processing performance of the alloy is improved.
 

Features of hot rolling:

1. Low energy consumption, good plastic processing, low deformation resistance, no obvious work hardening, easy rolling, and reduced energy consumption required for metal deformation.

2. Hot rolling usually uses large ingots and large reductions for rolling. The production rhythm is fast and the output is large, which creates conditions for large-scale production.

3. The as-cast structure is transformed into a processed structure through hot rolling, and the plasticity of the material is greatly improved through the transformation of the structure.

4. The characteristics of the rolling method determine that there is anisotropy in the properties of the rolled sheet. First, there are obvious performance differences in the longitudinal, transverse and high directions of the material. Second, there are deformation textures and recrystallization textures. There is a clear directionality in control performance

Hot-rolled coils are made of slabs as raw materials, and are made into strips by rough rolling mills and finishing mills after heating.

The hot steel strip from the last rolling mill of the finishing rolling is cooled to the set temperature by laminar flow, and is coiled into a steel coil by the coiler.

The finishing line (leveling, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) is processed into steel sheets, flat rolls and slitting steel strip products.

Classification:
 

Common carbon plate, excellent carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, container plate, etc. Rolled hard coils: Continuous rolling of hot-rolled pickled coils at room temperature. Hot rolled steel plate products include steel strip (coil) and steel plate cut from it. The steel strip (roll) can be divided into straight rolls and finishing rolls (sub-rolls, flat rolls and slitting rolls).

Advantage:

(1) Hot rolling can significantly reduce energy consumption and cost. The metal has high plasticity and low deformation resistance during hot rolling, which greatly reduces the energy consumption of metal deformation.

(2) Hot rolling can improve the processing performance of metals and alloys, that is, the coarse grains in the casting state are broken, the cracks are significantly healed, the casting defects are reduced or eliminated, the as-cast structure is transformed into a deformed structure, and the processing performance of the alloy is improved.

(3) Hot rolling usually adopts large ingot and rolling with large reduction, which not only improves production efficiency, but also creates conditions for increasing rolling speed and realizing continuous and automatic rolling process.

The allowable deviation of the thickness of the steel plate and steel strip shall comply with the provisions 
 

Nominal thickness (mm)	Thickness tolerance (mm)	Width direction after slicing	Rolling direction after slicing Thickness deviation (mm)

Hot steel Coil Application

Hot-rolled steel products are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels due to their excellent properties such as high strength, high toughness, easy processing, and excellent weldability. Therefore, there is a huge demand for HRC in the market.

Applications:
(1) After annealing, it is processed into ordinary cold rolling;
(2) The galvanizing unit with the annealing pretreatment device processes galvanizing;
(3) A panel that basically does not require processing.
 

Hot-rolled coil is the raw material for almost all steel products, such as cold-rolled coil, galvanized coil, pre-painted coil, angle steel, H Beam, flat steel, steel pipe, etc.
