The Most Comprehensive Introduction to Continuous Steel Rolling Process

Rolling steel ingots or billets with different chemical compositions and shapes into steel products that meet the requirements in shape and performance requires a series of processes. That’s the steel rolling process. Due to the wide variety of steel products with different specifications, shapes, steel types, and uses the steel rolling processes used to roll different products are also different.

Correctly determining the rolling process is of great significance to ensure output, quality, and cost reduction.

The steel rolling process is quite complicated. Although with the improvement of the quality requirements of rolled products, the expansion of the range of varieties, and the application of new technologies and new equipment, there will be corresponding changes in the various processes that make up the process, the entire steel rolling process is always composed of the following basic processes.

Normally, the billet rolling process is as follows:

Billet Heating—Billet Rough Rolling (Roughing Rolling Mill)—Continuous Rolling (Continuous Rolling Mill)—Shearing (Flying Shear)—Cooling (Cooling Bed)—Packing (Packing Table)

Preparation of steel billet: including cleaning of surface defects, removal of surface oxide scale and pre-heat treatment of billet, etc. If it is a continuous casting and rolling process, a continuous casting machine can be used to produce billets.

Billet heating: it is an important process in the hot rolling production process. A billet heating furnace is generally used to heat the billet. There are many types of billet heating furnaces, and there are different classification methods. Different heating furnaces have different characteristics and operating conditions and should be selected according to the specific conditions of the heating furnace billet. Billet heating furnaces commonly used in wire rod workshops are pusher-type heating furnaces and walking-type heating furnaces.

Billet rolling: it is the core of the whole steel rolling production process. The billet is rolled to complete the deformation process. The rolling process plays a decisive role in the quality of the product. The quality requirements of the finished product include three aspects: the geometric shape and dimensional accuracy of the product, the internal organization and performance, and the surface quality of the product.

Finish rolling of rolled pieces: it is the last process in the steel rolling process. And it is also a relatively complicated process. It plays an ultimate role in guaranteeing the quality of the product. The technical requirements of the products are different, and the content of the finishing process is also very different. The finishing process usually includes many specific processes such as cutting or coiling of steel, cooling after rolling, straightening, heat treatment of finished products, surface cleaning of finished products, and various coatings.
