The processing methods of marine steel plates include :
1.Raw material preparation: Select suitable low-alloy steel, high-strength steel, or weathering steel as raw materials. The raw materials need to undergo processes such as acid washing or surface treatment to ensure quality.
2. Smelting: Put the raw materials into the furnace for smelting, and adjust the properties and composition of the steel plate by adding appropriate alloying elements.
3. Steel quenching and tempering: Steel is quenched and tempered by heating and cooling in a special device, so that the steel plate has a uniform structure and good mechanical properties.
4. Steel filtration: The steel is passed through a filtration device to remove impurities and non-metallic inclusions.
5. Continuous casting: Pour molten steel into the continuous casting machine and solidify it into a continuous billet through a crystallizer.
6. Hot rolling: The cast billet is pre rolled and precision rolled through a hot rolling mill, adjusting the thickness and width to achieve the target size of the steel plate.
7. Temperature regulation: Adjust the structure and properties of steel plates by controlling the rolling temperature and speed.
8. Pre treatment: Surface treatment of steel plates, such as rust removal, cleaning, phosphating, etc., to ensure their smooth and polished surface.
9. Cold rolling and quenching: Hot rolled steel plates are re rolled by a cold rolling mill and then quenched to improve their strength and hardness.
10. Cutting and trimming: Use a cutting machine to cut and trim large-sized steel plates to meet design requirements. 11. Testing and quality control: Conduct quality testing on every step of the production process to ensure that the performance and quality of the steel plate meet the requirements.
12. Packaging and transportation: Packaging the final product for easy transportation and storage.
We have our own marine steel plate production line, we can ensure that the product is smooth and even.We accept third-party testing and also welcome customers to come for on-site inspection and testing. Appearance quality testing, hardness testing, chemical composition analysis, metallographic observation.
