Freight car girder steel

The main steels of truck beams are 5 10L and 6 10L. At home and abroad, automobile beam plates are mainly produced by continuous casting and hot rolling. The process design adopts the route of reducing carbon content and adding vanadium, niobium, titanium and other alloys, and selects different controlled rolling and controlled cooling processes to ensure the effective matching of strength and formability.

At present, there are three options for producing automobile beam plates in China: plate mill, conventional hot continuous rolling and thin slab continuous casting and rolling (CSP).

Automobile beam is a steel plate used to produce truck beam, which generally contains manganese, and its physical properties are specially developed for automobile beam. The thickness is 5mm-8mm, and the length and width can be produced according to the order of the automobile factory.

Wanhui New Material Company, an automobile beam manufacturer, has three cold bending units 10, including three large units, which can produce 700L automobile beam channel steel. The produced automobile beam has a flat appearance, no burr or scratch, and the qualified rate reaches 100%. 700L (ZQS700L girder plate produced by Baosteel) automobile girders are now supported by large enterprises such as China Heavy Truck Company and Commercial Vehicle Company.

Extended material

Influence of beam deformation on vehicles;

1, the deformation of the girder will make the force of the whole vehicle unbalanced, and it is easy to make the tire in one corner suffer from excessive force and puncture.

2. The control of the car is unstable, which is prone to accidents.

3. The vehicle can't drive normally in a straight line, and the vehicle deviates.
