SS400 Hot Rolled Carbon Steel Coil JIS G3101-2010 Mild Steel Coil Supplier

Short Description:

Hot-rolled steel coil products are made from slabs (mainly continuous casting billets) as raw materials, which are heated and then made into strips by rough rolling units and finishing units. The hot steel strip from the last mill of the finishing mill is cooled to the set temperature by the laminar flow and rolled into steel strip coils by the coiler.

2.All other specifications of round carbon steel pipes are available according to your requirement (OEM&ODM)! Factory price you will get from ROYAL GROUP.

The production process of straight seam welded pipe is simple, the production Hot Rolling Carbon Steel Coil efficiency is high, the cost is low, and the development is rapid. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the welded pipe with a larger diameter can be produced with a narrower billet, and welded pipes with different diameters can be produced with the same width billet. But compared with the straight seam pipe of the same length, the weld length is increased by 30~100%, and the production speed is lower.

Process of production

molten iron magnesium-based desulfurization-top-bottom re-blowing converter-alloying-LF refining-calcium feeding line-soft blowing-medium-broadband conventional grid slab continuous casting-cast slab cutting One heating furnace, one rough rolling, 5 passes, rolling, heat preservation, and finishing rolling, 7 passes, controlled rolling, laminar flow cooling, coiling, and packaging.

Product of Advantages

The advantages of steel coils mainly include:
Easy to process. Carbon Steel Coil can be processed and formed by cutting, bending, stamping, etc. without causing damage to the material, making them suitable for industrial production and manufacturing.
Easy to store and transport. Compared with flat materials, the form of steel coils can use space more efficiently and reduce storage and transportation costs.
Excellent mechanical properties. Steel coils have high strength, hardness and toughness and can meet various mechanical processing requirements.
Strong corrosion resistance. Many steel coils have special surface treatments, such as galvanizing, aluminum-magnesium-zinc plating, etc., which improve their corrosion resistance and can be used in harsh environmental conditions.
Very decorative. Color-coated steel coils have a smooth surface and bright colors. They not only provide good anti-corrosion functions, but also meet aesthetic requirements and are suitable for construction and home decoration.
Economical and lightweight. The material cost of steel coils is relatively low and has a lighter weight than cast parts, which helps to reduce structural mass and cost.
Good welding performance. Many steel coil materials have good welding properties and facilitate welding processing during the production process.
These advantages make steel coils widely used in automobile manufacturing, construction, home decoration, industrial manufacturing and other fields.

Packing and Transportation

Usually bare package

Transportation: Express (Sample Delivery), Air, Rail, Land, Sea shipping (FCL or LCL or Bulk)

How to pack steel coils
1. Cardboard tube packaging: Place the Carbon Steel Coil in a cylinder made of cardboard, cover it at both ends, and seal it with tape;
2. Plastic strapping and packaging: Use plastic straps to bundle the steel coils into a bundle, cover them at both ends, and wrap them with plastic straps to fix them;
3. Cardboard gusset packaging: Fasten the steel coil with cardboard cleats and stamp both ends;
4. Iron buckle packaging: Use strip iron buckles to bundle the steel coils into a bundle and stamp both ends
In short, the packaging method of steel coils needs to take into account the needs of transportation, storage and use. The steel coil packaging materials must be strong, durable and tightly tied to ensure that the packaged steel coils will not be damaged during transportation. At the same time, safety needs to be paid attention to during the packaging process to avoid injuries to people, machinery, etc. due to packaging.
