对低合金高强度调质钢的轧制方式及轧后冷速进行了研究。结果表明：试验钢采用不同轧制方式及冷速获得不同的淬火前初始组织及力学性能，但调质后却具有相同的微观组织和力学性能。低合金高强度调质钢建议采用一阶段的轧制方式，冷速不宜过低。调质后的试验钢有较高的均匀性，与TMCP相比，具有更优异的强塑性和强韧性。

Low-alloy high-strength quenched and tempered steel rolling method and the cooling rate after rolling has been studied. The results showed that: test steel using different rolling methods and cooling rate to obtain different initial microstructure and mechanical properties before quenching, but they have the same microstructure and mechanical properties after quenching and tempering. Low-alloy high strength quenched and tempered steel suggested using one-stage rolling method, cooling rate should not be too low. Quenched and tempered steel after the tests have a high uniformity, as compared with the TMCP has superior strength and plasticity and strength and toughness.
