Quenching process play a significant role in the quality of steel strip

Production and processing of steel strip is essential to the quenching process, the stand or fall of quenching technology directly determine the quality of the finished product steel strip. In the process of the quenching process of quenching temperature, heating time and the control of quenching medium is need very strict, every step may affect the quality of the steel belt. Steel quenching process, different quenching temperature, heating time and quenching media have very big effect on the microstructure and mechanical properties of transition. When quenching temperature increased from ℃ ℃, tempered troostite transformation degree increased gradually, and from ℃ began to change significantly; Tensile strength ( Rm) , yield strength, Rel) Improve MPa and MPa, respectively, while elongation ( A) Reduced. %。 Quenching heating time from was extended to min min, phase transition into more fully, tempered troostite organization are refined gradually; Compared with oil quenching, water less residual austenite after quenching, organize more small, tensile strength improve MPa, the elongation decreases. %。 Prolonged heating quenching and the spheroidizing annealing can improve quantity of martensitic transformation, but the martensite zui u-turn evaluation of extremum quenching heating time. So steel belt manufacturer want to ensure the quality of products, for quenching process must be a careful and systematic study. In this way can we get a high strength, good toughness and hardness. In addition to the quenching steel strip production need to use the quenching process, some hardware tools, springs, cutting tools, woodworking band saw, automobile clutch plate, clock spring, lock, shoes materials, textile equipment, all kinds of industry such as packaging steel strip has demand. A: during the outbreak of bluing production and steel belt. 。 。 Next article: heat treatment of steel belt manufacturer production process. 。 。
