METHOD OF MANUFACTURING HOT ROLLED COIL FOR PREVENTING FORM TRANSFORMING |
| 摘要 |
<p>PURPOSE: A method for manufacturing hot-rolled coils for preventing deformation is provided to improve the quality of products by providing optimum rolling and cooling conditions for preventing deformation of a hot-rolled coil due to its weight. CONSTITUTION: A method for manufacturing hot-rolled coils for preventing deformation comprises the steps of: preparing steel slab including quenching elements(ST100), reheating the slab(ST200), hot-rolling the reheated slab to obtain a steel sheet(ST300), cooling the hot-rolled steel sheet in a water cooling zone by shear controlled cooling(ST400), and coiling the cooled steel sheet(ST500).
