There are two main functions of steel rolling. On the one hand, it is to obtain the required shape, such as: steel plate, strip steel, wire rod and various types of steel; on the other hand, it is to improve the internal quality of the steel.
Rolling steel ingots or billets with different chemical compositions and shapes into steel that meets the requirements of shape and performance requires a series of processes. The combination and sequence of these processes are called technological processes.
Our common automobile sheet, bridge steel, boiler steel, pipeline steel, rebar, rebar, including train wheels, etc., are all processed through steel rolling production lines.
The process of rolling steel production is very complicated, and with the improvement of the quality requirements of rolled products, the expansion of the variety range and the application of new technologies and new equipment, each process of the entire process will have corresponding changes.
However, the entire steel rolling production process is generally unchanged, and always consists of the following basic processes. Today, the editor of Judian will introduce the process of steel rolling production to you.
1. Preparation of blanks: cleaning of surface defects of blanks, such as removal of iron oxide scale and pre-heat treatment of blanks, etc.
2. Heating of the billet: This step is an important part of the hot rolling production process.
3. Steel rolling: the core of the entire steel rolling production process. The billet completes the deformation process by rolling. The rolling process plays a decisive role in the quality of the product.
4. Finishing: It is the last process in the steel rolling production process, and it is also a relatively complex 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 includes many specific processes such as cutting, coiling, cooling after rolling, straightening, heat treatment of finished products, surface cleaning of finished products and various coloring of steel.
Due to the variety of steel, the specifications, shapes, steel types and uses are different, so the technological processes used for rolling different products are also different. Reasonable technological process is of great significance to ensure product output, quality and reduce costs.
An excellent production line requires staff to put forward reasonable process parameters on the basis of in-depth analysis of the characteristics of the rolling process, complete the quality requirements, and make the rolling mill have good technical and economic indicators.
This is what we share today about the continuous rolling steel production process, I hope it can be helpful to you. Welcome to pay attention to our Luoyang Judian, let us provide you with more steel rolling mill services.
