Steel structure engineering rectification and forming process

Steel structure workshop as a leader in the steel industry, we often see it in the major construction sites, in order to ensure the quality of the whole site, steel structure manufacturers in production strictly in accordance with the production indicators, to choose raw materials, as well as the detection of the production line, the quality of the product must be done.

The steel structure we use in the enterprise will have a lot of processing procedures in the processing, among which the correction molding is important, let's look at it below.

A, correcting

1. Cold correction of finished products is generally carried out by mechanical force such as flange leveler, straightening machine, hydraulic press and press.

2, flame correction, heating methods are point heating, line heating and triangle heating three.

(1) Medium carbon steel will crack due to deformation, so medium carbon steel is generally not flame correction.

(2) Ordinary low alloy steel should be cooled slowly after heating and rectification.

(3) The heating temperature of low carbon steel and ordinary low alloy steel is generally 600 ~ 900℃, and 800 ~ 900℃ is the ideal temperature of thermoplastic deformation, but not more than 900℃.

Second, the molding

1, hot processing: low carbon steel is generally in 1000 ~ 1100℃, hot processing termination temperature should not be less than 700℃. The heating temperature is 500 ~ 550℃. Steel brittleness, no hammering and bending, otherwise easy to fracture steel.

2, cold processing: steel processing at room temperature, most of the use of mechanical equipment and special tools.

In general, when we are processing steel structure, we should also do a good job of correction molding, so that in the late use of the party can be used for a long time. We generally make a full understanding of the steel structure before using it, so that we can not only better use it, but also reduce accidents in the process of use, increase its benefits, and make some contributions to the building materials industry.
