Production Principles of European Standard H-beam Steel

H-beam is a commonly used steel material. It has the characteristics of high strength, high stability, strength, and seismic resistance, and is widely used in many engineering projects. The production of this type of steel needs to follow the production principle of European standard H-beam steel, which will be introduced in detail below.

The production principle of European standard H-beam steel is divided into two main processes: external converter smelting and continuous casting and rolling.

Smelting process of external converter

The main purpose of this process is to produce high-quality steel. The smelting process requires extracting iron from iron ore, coke, and limestone. During this process, ore and coke react in the blast furnace to produce a byproduct called blast furnace slag. Slag is separated based on density, with steel settling to the bottom and slag floating at the top.

With the separation of steel and slag, the slag is placed in the converter outside the furnace and other chemical treatment equipment for further treatment. During this process, the proportion of steel and slag must be strictly controlled, otherwise the produced steel will have defects and affect quality.

Continuous casting and rolling process

After the smelting is completed, the steel needs to be continuously cast into embryos or processed into plates. The entire process requires the use of steam, hydraulic, and mechanical equipment. Continuous casting is the process of pouring molten steel from smelting into a mold, which is continuously cooled and squeezed by water to condense into strip steel of different shapes and lengths, and then rolled into appropriate specifications by a rolling mill.

The main function of a rolling machine is to flatten and scrape the continuously cast billets or plates, and bundle or fold them as needed. This process requires precise engineering design and mechanical properties to ensure the stability and quality of the steel.

Overall, the production process of European standard H-beam steel needs to follow the principles of high quality and low energy consumption to ensure the safe and reliable quality of the produced steel. With the continuous development of technology, the technology and equipment for H-beam production are constantly updated and advanced, providing more high-quality steel products for various industries.
