H-beam production process

The Production Process of H Steel

H-Steel is a popular type of steel used in a number of construction and other applications due to its superior strength and durability. This type of steel is commonly used in the construction of bridges, buildings, and other infrastructure projects. It is also used in the construction of various machines, such as heavy machinery and vehicles. The production process of this type of steel is fairly simple and can be divided into three main stages: forming, heat treatment, and finishing.

Forming

The first stage of H-Steel production is forming. During this stage, the steel is heated and then shaped into the desired shape and size. There are two common ways of doing this. The first method is forging, which is done by pressing heated bars of steel into a specific shape. The second method is rolling, which is done by passing sheets or plates of heated steel through rollers and then pressing them into the desired shape. Forging is used most often for large shapes, while rolling is more often used for flat surfaces or small sections.

Heat Treatment

The second stage of H-Steel production is heat treatment. During this stage, the steel is heated to temperatures in excess of 1,100 degrees Fahrenheit (590 degrees Celsius). This is done mainly to give the steel the desired strength and toughness. Specialized heat-treat furnaces are used to heat the steel and several different types of heat treatments can be used, such as normalizing, annealing, quenching, and tempering.

Finishing

The third and final stage of H-Steel production is finishing. During this stage, the steel is cut, drilled, milled, and otherwise machined into the desired shape and size. It is then ready for the installation or assembly process. This stage also includes any surface treatments that are needed, such as painting and plating.

H-Steel is a popular and versatile type of steel that has a wide range of applications due to its superior strength and durability. The production process consists of three stages: forming, heat treatment, and finishing. This process is relatively simple, but it does require specialized equipment and experienced personnel to ensure that the best results are achieved.

The production process of H-beam steel is mainly composed of four parts: blank casting, pre-processing (rolling course), welding and heat treatment, and finishing process.

1.Ladle casting: H-beam steel is a kind of large section steel, so large bamboo casting is adopted. According to the requirements of blank manufacturing, medium frequency electric furnace ore smelting is used for smelting and refining, and ladle refining is adopted for dephosphorization treatment.

2. Pre-processing(rolling course): The ladle blank is heated in the walking beam furnace, and the axial extrusion is produced by the plate mill and finishing mill. H-beam steel is formed through two-time symmetry rolling in the finish mill and welded into H-beam steel.

3.Welding and heat treatment are essential processes for H-beam steel. The welding process includes single side welding, double side welding and butt welding, etc., as well as preheating and heat treatment before welding, welding and tempering after welding. After welding, the product can be treated thermal, normalized and quenched. The finishing process includes trimming, chamfering, opening holes and straightening.

4Final finishing: Surface finish is a very important step in H-beam steel production process. It is necessary to polish the surface of H-beam steel with smooth surface, passivation and shot blasting.
