| Abstract: | In view of the low mechanical properties of hot rolled strip steel in the research and development process of 10 mm thick 700L steel in a iron and steel enterprise, the key factors affecting the mechanical properties of 700L products were studied and analyzed one by one by the means of six sigma measurement tool according to the previous production data of 700L products. Finally, the main reason for the low mechanical properties of the products was found out. At the same time, the coiling temperature control value of 700L product with 10 mm thickness under the composition system and production process conditions was proposed. |
