| titleOfInvention | A kind of hot rolling large roughness surface weathering steel and its manufacturing method |
| abstract | The invention discloses a kind of hot rolling large roughness surface weathering steels, main chemical compositions are by mass percentage are as follows: C0.02~0.08%, Si 0.10~0.30%, Mn 0.15~0.40%, S≤0.008%, P≤0.02%, Cu 0.20~0.40%, Cr0.20~0.50%, Ni 0.10~0.40%, Ti 0.010~0.030%, Als content≤0.03%, remaining is iron and inevitable impurity.Hot rolling large roughness provided by the invention surface weathering steel is that one kind exempts from the direct coating weathering steel of sandblasting, and surface is surface layer Fe 3 O 4 + middle layer Fe/Fe 3 O 4 + bottom Fe 3 O 4 Three layers of scale structure of composition, this scale structure and steel matrix binding force are good, in surface roughness transfer process when smooth, only occur to fall off on a small quantity, it is not fallen off in the technical process such as deformation, welding, surface roughness Rz can be according to coating demand control at 20~50 μm, and soluble surface chloride content can be controlled in≤10 μ g/cm 2 , reach the requirement for exempting from the direct coating of sandblasting. |
