In order to be more conducive to product processing, steel shapes can be described as diverse. Some are in the form of steel ingot, some are in the form of steel pipe, and some are rolled together by sheets of steel plate, which is commonly known as "hot rolled coil".

In this issue, we mainly introduce science to everyone. The production process and use of hot rolled coils are related:

Product interpretation:

In terms of product definition, it uses slab as raw material and is heated to make strip steel by rough rolling mill and finish rolling mill. The hot steel strip from the last finishing mill is cooled to the set temperature through laminar flow, rolled into steel strip coil by coiler, and formed after cooling.

Production process

1、 Raw material preparation
In the process of raw material preparation, it is mainly aimed at the specific application level of hot rolled coils. Generally speaking, ordinary carbon structural steel, low-alloy steel, alloy steel and other materials can be used as the most basic slab raw materials. After the materials are ready, pay attention to cleaning in place to ensure that the material surface is not clean and tidy.

2、 High temperature heating
After the materials are ready, use the crane to put the slab into the high-temperature furnace for heating treatment. Because the hot rolling coil is to make the slab into strips and directly change its shape, the temperature in the heating furnace must be controlled in place.

3、 rolling form
When the slab in the high temperature furnace is heated and the temperature meets the requirements, it starts to enter the rolling shape link. In this process, the slab material under high temperature is rolled into the required coil shape by using rollers.
four 、 Hot rectification
Hot rolled coil has a clear product application direction, so it also has a high standard for shape requirements. stay rolling After the completion of the process, some product shapes may not meet the standard, and at this time it is necessary to enter the hot state correction process to ensure that all product shapes are in place.

five Cooling forming
After the completion of hot straightening, the original slab material has become the shape of steel coil. At this time, it enters the last process, cooling and forming. After this process is completed, the hot rolled coil is officially completed. Next, according to the different needs of users, they are processed into steel plates, flat coils and slitting steel strips.

3、 Product use:

In terms of product performance, hot rolled steel coils have excellent properties such as high strength, good toughness, easy processing and forming, and good weldability.

It can be widely used in: ships, automobiles, bridges, construction, machinery, pressure vessel petrochemical equipment, automobile industry, agricultural vehicle industry, shipbuilding industry, iron tower industry, steel structure industry, electric power equipment, lamp pole industry, signal tower, spiral steel pipe industry, and other industries.
