As everyone knows, the steel structure we use in the enterprise will have many processing procedures during processing, and the corrective forming is important. Let’s look at it below.

1. Correction

1) The cold correction of the finished product is generally performed with mechanical forces such as flange levelers, straightening machines, hydraulic presses, and presses.

2) Flame correction, heating methods are point-shaped heating, linear heating and triangular heating.

① The heat correction heating temperature of low carbon steel and ordinary low alloy steel is generally 600～900℃, and 800～900℃ is the ideal temperature for thermoplastic deformation, but it is not allowed to exceed 900℃.

②Medium carbon steel will crack due to deformation, so medium carbon steel generally does not need flame correction.

③Ordinary low-alloy steel should be slowly cooled* after heating and straightening.

2. Forming

1) Hot working: For low-carbon steel, it is generally 1000～1100℃, and the termination temperature of hot working should not be lower than 700℃. The heating temperature is 500～550℃. The steel is brittle. Hammering and bending are strictly prohibited, otherwise the steel will be easily broken.

2) Cold processing: steel is processed at room temperature, and most of them are processed by mechanical equipment and special tools.

Generally, when we are processing the steel structure, we should also do a good job of correcting and forming, so that it can be used for a long time when it is used later.
