Manufacturing process and application of EN 10025 S235JRG2 steel plate

The manufacturing process of EN 10025 S235JRG2 steel plate includes the following steps:

1. Raw material preparation: select S235JRG2 steel billets that meet the standard requirements, and usually use continuous casting machines in steelmaking plants for casting.

2. Steel billet pretreatment: The steel billet is heated to remove surface oxides and impurities, and make it reach a certain degree of plasticity and plasticity.

3. Hot rolling: the pretreated steel billet is sent to the hot rolling unit, and is manufactured into the required thickness and width through deformation at high temperature. During this process, the billet is plastically deformed by the friction and pressure of the rollers to form a flat sheet.

4. Cooling: The hot-rolled plate needs to be cooled to control the grain size of the EN 10025 S235JRG2 steel plate and obtain the required mechanical properties.

5. Cutting: According to the customer's requirements, cut the cooled steel plate according to the size requirements.

6. Surface treatment: Carry out surface treatment on the cut steel plate, such as painting, anti-rust, etc., to prolong the service life of the steel plate.

7. Inspection and packaging: Quality inspection is carried out on the manufactured steel plates, and appropriate packaging methods are adopted to ensure that they are not damaged during transportation and storage.

EN 10025 S235JRG2 steel plate is a non-alloy structural steel, which is widely used in construction, machinery manufacturing, bridges, ships and other fields. Specific uses are as follows: Building structures: such as buildings, bridges, underground tunnels, etc. Machinery manufacturing: such as automobile manufacturing, machine tool manufacturing, agricultural machinery manufacturing, etc. Ship construction: such as hull components, decks, portholes, bow and stern structures, etc. Pipeline manufacturing: such as oil, natural gas pipelines, etc.

In conclusion, EN 10025 S235JRG2 steel plate has a wide range of applications, and its high strength, excellent weldability and plasticity can meet various engineering needs.
