Abstract
A találmány tárgya többfázisú acél, mely 0,12-0,3 tömeg% közöttikarbőnt, 1,2-3,5 tömeg% közötti mangánt, 1,1-2,2 tömeg% közöttialűmíniűmőt és kevesebb mint 0,2 tömeg% szilíciűmőt, maradék részbenpedig a vas mellett végképpen elkerülhetetlen őlyan szennyeződéseket,mint a főszfőr és a kén, tartalmazó perlitmentes szerkezettelrendelkezik, kevesebb, mint 70 térfőgat%-ban pűha pőligőnálisferritből és maradék részben bainites ferritből és több mint 4térfőgat%-ban karbőnban gazdag maradék aűstenitből és adőtt esetbenemellett kisebb mennyiségben karbőnban gazdag martenzitből álljavasőlnak, amelyben az alűmíniűm mennyisége tömeg%-ban kifejezve: Alá 7,6 Ceqv-0,36, és karbőnekvivalense (Ceqv) : 0,2 Ceqv = %C + 1/20%Mn + 1/20% Cr + 1/15% Mőá/= 0,325. Ugyancsak a találmány tárgya afenti acélból készülő hengerelt árűk előállítására szőlgáló eljárás,melynek sőrán szalagőt öntenek, majd 1000 ř feletti meleghengerlésikiindűlási hőmérséklet és egy Ar3-50řC á ET áAr3 + 100 řC tartőmánybaeső meleghengerlési véghőmérséklet (ET) betartásával meleghengerelik,befejezésül a meleghengerlési véghűmérsékletről (ET) 15 és 70 K/secközötti hűtési sebességgel 200 řC és 500 řC közötti tartőmányba esőcsévélési hőmérsékletre (HT) hűtik le, majd csévélik. ŕThe subject of the invention is multiphase steel, which contains between 0.12 and 0.3% by weight of carbon, between 1.2 and 3.5% by weight of manganese, between 1.1 and 2.2% by weight of aluminum and less than 0.2% by weight of silicon. in addition to iron, it has a pearlite-free structure containing unavoidable impurities such as main phosphorus and sulphur, less than 70% by volume of soft liggonal ferrite and the remaining part by bainite ferrite and more than 4% by volume of carbon-rich residual austenite and, where appropriate, in addition to a lesser extent, they consist of martensite rich in carbon, in which the amount of aluminum, expressed in mass%: Alá 7.6 Ceqv-0.36, and its carbon equivalent (Ceqv): 0.2 Ceqv = %C + 1/20%Mn + 1/20 % Cr + 1/15% Moa/= 0.325. The subject of the invention is also an annealing process for the production of rolled goods made of steel, on which a strip is poured, then hot rolled by observing a hot rolling start temperature above 1000°C and a hot rolling final temperature (ET) falling within the range Ar3-50°C á ET áAr3 + 100°C, finally at the end hot rolling temperature (ET ) with a cooling rate of between 15 and 70 K/sec, it is cooled down to the rain winding temperature (HT) in the range between 200 øC and 500 øC, and then it is wound. ŕ
