热轧板表面抗剥落性氧化铁皮结构及其控制工艺
摘要：
热轧板表面抗剥落性氧化铁皮结构及其控制工艺，属于轧钢技术领域。本发明采取双排除鳞工艺，高压水除鳞压力控制为≥16MPa，采用高温快轧模式，精轧后采用前段稀疏冷却模式，卷取温度控制在650℃以下，最终保证4-14mm厚度的热轧板表面氧化铁皮厚度≤10.8um，氧化铁皮结构中Fe3O4的比例控制在45％～68％，FeO的比例控制在23％～42％，Fe2O3的比例控制在8％～15％。
摘要（英）：

The invention discloses an anti-stripping iron oxide scale structure on the surface of a hot rolled plate, and a control process for the anti-stripping iron oxide scale structure, and belongs to the technical field of steel rolling. The control process is characterized in that a dual-discharge descaling process is adopted, wherein high-pressure water descaling process is controlled to be higher than or equal to 16 MPa; a high-temperature quick rolling mode is adopted; a front-stage sparse cooling mode is adopted after finish rolling; a rolling temperature is controlled to be lower than 650 DEG C; and finally, the thickness of the iron oxide scale structure on the surface of the hot rolled plate with a thickness of 4-14mm is controlled to be smaller than or equal to 10.8 microns, the proportion of Fe3O4 in the iron oxide scale structure is controlled to be 45%-68%, the proportion of FeO is controlled to be 23%-42%, and the proportion of Fe2O3 is controlled to be 8%-15%.
