| titleOfInvention | Thick steel plate for welded steel pipe excellent in scale peeling resistance and material uniformity, manufacturing method thereof, and welded steel pipe |
| abstract | The present invention provides a steel plate having excellent scale peeling resistance and material uniformity, a manufacturing method for efficiently producing the steel plate at low cost, and a welded steel pipe. A steel slab having a predetermined component is heated to 1000 to 1250 ° C., subjected to descaling treatment for removing scale on both sides by spraying high-pressure water onto the steel slab, and then hot rolling with N passes. And the descaling process is performed twice or more during the rolling pass from the (N-4) th pass of the hot rolling to the final Nth pass, and FT = 845− [500/3] × [(1.5 [% Si] -2 [% Cu] -2 [% Ni]-[% Cr]) A method of manufacturing a thick steel plate for welded steel pipes that performs accelerated cooling at a cooling rate of 10 ° C / second or higher from 600 ° C to less than 600 ° C, stops the accelerated cooling, and then air-cools. [Selection figure] None |
