Application Of Hot Rolled Steel Sheet And Cold Rolled Steel Sheet

Jun. 10, 2020

By definition, steel ingots or billets are difficult to deform at room temperature and are not easy to process. Generally, they are heated to 1100-1250°C for rolling. This rolling process is called hot rolling. The temperature of the hot-rolled sheet is high, so the deformation resistance is small, and a large amount of deformation can be achieved. Taking the rolling of steel plates as an example, the thickness of the continuous casting billet is generally about 230mm, and after rough rolling and finishing rolling, the final thickness is 1~20mm. At the same time, due to the small width-thickness ratio of the Plate Steel, the dimensional accuracy requirements are relatively low, and the shape problem is not prone to occur, and the main control is the convexity. For the requirements of the structure, it is generally achieved by controlled rolling and controlled cooling, that is, the opening temperature, final rolling temperature and coiling temperature of the finishing rolling are controlled to control the microstructure and mechanical properties of the strip. The Coating Galvanized Steel Strip Manufacturer will look at their types and uses together with you.



1. Structural steel


Mainly used in the production of steel structural parts, bridges, ships and vehicles.


2. Weather-resistant steel


The addition of special elements (P, Cu, C, etc.) has good corrosion resistance and atmospheric corrosion resistance. It is used in the production of containers and special vehicles, and is also used in building structures.


3. Steel for automobile structure


High-strength steel plate with good stamping performance and welding performance, used for automobile FRAME, WHEEL and other production.


4. Hot rolled special steel


Carbon steel, alloy steel and tool steel for general mechanical structures are used in the production of various mechanical parts after heat treatment.


5. Cold rolled original plate


Cold Rolled Steel is used to produce a variety of cold rolled products, including CR, GI, color coated plates, etc.


6. Steel plate for steel pipe


With good processing performance and compressive strength, it is used to produce high-pressure gas pressure vessels filled with LPG, acetylene gas and various gases with an internal volume of less than 500L.


7. Steel plate for high-pressure container


With good processing performance and compressive strength, it is used to produce high-pressure gas pressure vessels filled with LPG, acetylene gas and various gases with an internal volume of less than 500L.


8. Stainless steel plate


Stainless steel has good corrosion resistance, and is mainly used in food industry, surgical equipment, aerospace, petroleum, chemical industry and other industries.
