Hot - Rolled Corten Plate refers to a type of steel plate made of corten steel through the hot - rolling process. Here is a detailed introduction:

Definition and Composition1

Definition: Corten steel is a low - alloy steel series between ordinary steel and stainless steel, also known as weathering steel. Hot - rolled corten plates are produced by adding a small amount of corrosion - resistant elements such as copper, chromium, and nickel to ordinary carbon steel and then subjecting it to hot - rolling processing.

Composition: The alloy composition and weight percentage content of corten steel are generally C: ≤0.12, Si: 0.25 - 0.75, Mn: 0.2 - 0.5, S ≤0.02, P: 0.06 - 0.12, Cu: 0.25 - 0.5, Cr: 0.3 - 1.25, Ni: 0.12 - 0.65, and the rest is Fe and trace elements.

 

 

 

 

 

 

 

 

Aesthetic Appearance: As time passes, the natural color change caused by the surface rust gives it a unique artistic feel, which is widely used in architectural decoration and artistic creation.

Applications1

Infrastructure: It is used in the construction of bridges, towers, and other structures, which can reduce the maintenance cost of steel structures and prolong their service life.

Architecture and Art: Due to its unique rust - colored appearance, it is widely used in building facades, sculptures, garden landscapes, and other fields, which can create a unique artistic effect.

Production Process1

Smelting: The process of smelting corten steel generally includes charging refined materials into the furnace, smelting (converter or electric furnace), micro - alloying treatment, argon blowing, LF refining, low - superheat continuous casting (feeding rare - earth wire), and controlled rolling and cooling.

Hot - Rolling: The molten steel is cast into slabs through continuous casting, and then the slabs are heated and rolled at high temperatures. Through a series of hot - rolling processes, the corten steel plates with the required thickness, width, and length are obtained. During the hot - rolling process, the microstructure and properties of the steel can be optimized by controlling the rolling temperature, speed, and reduction ratio to improve the performance of the hot - rolled corten plates.
