| titleOfInvention | A kind of high titanium low cost Q345B hot rolling acid-cleaning plates and its production method |
| abstract | The problems such as a kind of high titanium low cost Q345B hot rolling acid-cleaning plates and its production method, the Q345B hot rolling acid-cleaning plate production costs for mainly solving prior art production are excessively high, and lumber recovery is low, insufficient formability, poor welding performance.The present invention provides a kind of high titanium low cost Q345B hot rolling acid-cleaning plates, is made of following components according to weight percent：C：0.12% 0.16%, Si≤0.35%, Mn：0.10% 0.50%, P≤0.020%, S≤0.015%, Als：0.015% 0.040%, Ti：0.045% 0.070%, N≤0.006%, surplus is iron and inevitable impurity.The present invention also provides its production method, step is as follows：Hot rolling acid-cleaning plate continuous casting billet is prepared according to above-mentioned each component and weight percent proportioning, and heating and thermal insulation, high-pressure water descaling, roughing, finish rolling batched after section cooling, and final obtained performance meets the Q345B hot rolling acid-cleaning plates of the requirements of GB/T1591 2008.The present invention realizes that the defects of production cost is greatly reduced, significantly reduces banded structure, manganese sulfide inclusion object, reduces the crack sensitivity in strand corner, effectively prevent from sticking up skin generates. |
