Seamless tube Brief introduction:
After quenching and tempering, the parts have good comprehensive mechanical properties and are widely used in all kinds of important structural parts, especially those connecting rod, bolt, gear and shaft under alternating load. But the surface hardness is low, not wear-resisting. Conditioning or surface hardening can be used to improve the surface hardness of parts.

CK45 steel honed tube performance:
Tensile strength: no less than 600Mpa
Yield strength: no less than 355Mpa
Elongation: 10%
Shrinkage: 40%
Impact work: 39J
shaft material shaft parts according to the different working conditions and requirements of the choice of different materials and heat treatment with different specifications (such as quenching, normalizing, quenching, etc.) in order to obtain the strength, toughness and wear resistance of certain.
steel is commonly used in shaft parts, it is cheap after quenching and tempering (or normalizing), can obtain better cutting performance, but also can obtain high strength and toughness properties, surface hardness after quenching can reach 45 ~ 52HRC.
Research on roll pass matching in seamless steel tube hot rolling process:
For a given roll rolling plan in seamless steel tube production process under the matching problem, in order to minimize the amount of turning roll as the optimization objective, is established to comprehensively consider the 0-1 integer programming model of static roll roll and roll for reuse, reuse the dynamic roll matching two kinds of circumstances. The static roll matching problem, put forward the matching criteria for at least the amount of turning, and prove the optimality criterion; the dynamic roll matching problem, prove the matching criterion in the least amount of turning, matching dynamic roll pass results is not inferior to the static roll matching. Finally, based on the analysis of the nature of the problem, a heuristic algorithm based on dynamic candidate roll set and minimum turning quantity criterion is designed for the problem model. The effectiveness of the model and algorithm is verified by numerical examples and simulation experiments based on actual production data.
