The hydraulic section steel cold bending machine is widely used in the bending of I-beam, channel steel and section steel in road tunnels, railway tunnels, subway tunnels, water conservancy and hydropower diversion culverts, natural gas pipelines, communication pipelines, undergr...

Before using the cold bending machine, check in advance whether the circuit of the cold bending machine and the hydraulic oil of the body are abnormal. The processing site of the cold bending machine must have enough steel turnover space, and the operators who operate the cold be...

The I-beam cold bending machine realizes continuous operation on the basis of ensuring the strength of the steel, and the section is economical and reasonable, saving materials.The cross-sectional shape of the cold-formed steel cold-bending machine can be designed according to th...

1. The roll sleeve of the roll forming machine is sprayed with 1/4 concentration of anti-oxidation and decarburization medium before tempering and quenching to reduce decarburization and oxidation of the roll sleeve surface, improve material utilization, and reduce decarburizatio...

If Steel Profile Roller Shutter Door Machine adopts a new roll production process, starting from the source of material control, and further extending the service life of the roll through reasonable thermal processing methods, it will be beneficial to roll manufacturers and steel...

Apply online grinding roll technology and work roll traverse to reduce roll wear, extend the rolling kilometers of the strip, and reduce the number of roll changes.The damage of the roll is caused by the interaction and mutual influence of many factors, and its damage forms are v...

The rolls of the roll forming machine include work rolls and backup rolls, which are one of the key parts of the roll forming machine and are installed in the roll forming machine. In the production of hot-rolled strip steel, the consumption of rolls is very large, especially the...

In addition to the conventional mechanical properties, various rolling mills have put forward a series of special requirements for the performance of the rolls, which are different from other products.1. Fracture resistance. The ability of roll body and roll neck to withstand wor...

The metallurgical roll is an essential part of the metal roll forming machine. It is used as a special tool to make the metal deform plastically and roll out various rolled products.Due to the special conditions of the rolls, large consumption and closely related to the quality a...
