Steel Coil introduction

Steel Coil introduction

Steel coil, also known as coil steel. The steel is rolled by hot pressing and cold pressing. In order to facilitate storage and transportation, it is convenient to carry out various processing (such as processing into steel plates, steel strips, etc.)
The forming coils are mainly hot rolled coils and cold rolled coils. Hot rolled coils are processed before the billet is recrystallized. Cold-rolled coil is the follow-up process of hot-rolled coil.

How to polish the steel coil

1, steel coil polishing, you can use mechanical polishing method, this method is generally manual, that is, the position of the steel coil concave and convex become smooth, the process will use sandpaper and oil stone bar props, through the mechanical polishing of the steel coil, you can improve the quality of the surface of the steel coil.

2, when polishing the steel coil, you can also use chemical polishing, this polishing method uses a chemical reaction, the steel coil raised position becomes flat, the biggest advantage is that the process does not need to use too complex equipment, and the polishing effect is good.

3, steel coil polishing can also use electrolytic polishing method, although the principle of chemical polishing method is very similar, but in comparison with the two, the polishing effect of electrolytic polishing will be better, because this polishing method is the use of electrolytic solution to the steel coil surface raised position to become flat.

Coil of steel

Also known as coil steel. Strip steel is made from slab as raw material by roughing mill and finishing mill after heating. Hot steel strips from the final finishing mill are cooled to a set temperature by laminar flow and are rolled into coils by the coiler. The cooled steel coil is processed by different finishing lines according to the different needs of users into steel plate, flat coil and slitted steel strip products.
