S690QL1 high strength steel plate production process
1. Melting: The production process starts with the melting of the raw materials in a furnace. The raw materials typically consist of iron ore, coal, and limestone, which are heated to extremely high temperatures to form a molten metal.
2. Refining: Once the raw materials have been melted, the impurities are removed through a refining process. This involves the use of various chemical and physical methods to remove unwanted elements from the molten metal.
3. Continuous Casting: The molten metal is then poured into a continuous casting machine, where it is molded into the desired shape. The continuous casting process helps ensure that the steel plate has a uniform thickness and consistent mechanical properties.
4. Rolling: The steel plate is then rolled to the desired thickness and shape. This involves passing the steel through a series of rollers that apply pressure to shape and form the steel into the desired dimensions.
5. Heat Treatment: The final step in the production process is heat treatment. This involves subjecting the steel plate to high temperatures and cooling it rapidly to create a hardened surface that is resistant to wear and tear.
