Steel structure correction forming process
The steel structure we use has many processes during processing. Correction and forming are the most important. Let's understand it together. 1. Correction 1). The cold correction of the finished product is generally performed by mechanical forces such as flange levelers, straightening machines, hydraulic presses, and presses. 2). Flame correction, there are three heating methods: point heating, linear heating and triangular heating. ①The 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.
