<p>The thermomechanic treatment process for heavy plate (1) for increasing low temperature toughness, comprises heating the heavy plate, partially- and completely transforming through rollers and then cooling at ambient temperature, where the heavy plate heated for a partial form over AC3 temperature after its end forming. The heavy plate is cooled between part- and end-forming below Ar3 temperature and is inductively heated over Ac3 temperatures. The heavy plate is cooled on the part form below Ar1 temperature. The heavy plate is inductively heated at its temperature for endforming. The thermomechanic treatment process for heavy plate (1) for increasing low temperature toughness, comprises heating the heavy plate, partially- and completely transforming through rollers and then cooling at ambient temperature, where the heavy plate heated for a partial form over AC3 temperature after its end forming. The heavy plate is cooled between part- and end-forming below Ar3 temperature and is inductively heated over Ac3 temperatures. The heavy plate is cooled on the part form below Ar1 temperature. The heavy plate is inductively heated at its temperature for endforming and subsequently subjected to end-forming. The core layer of the heavy plate is inductively heated at 20[deg] C over Ar3 temperature. The heavy plate is cooled with a roller temperature of greater than Ar3 temperature. The sheet metal is inductively heated by a longitudinal field heating (5). The heavy plate is subjected to a reversing part- and/or end rolling. An independent claim is included for a heavy plate.</p> |
