As integral components within the crane traveling mechanism, wheel Sets play a pivotal role in various lifting machines, including single-girder overhead cranes, double-girder overhead cranes, gantry cranes, port cranes, and other rail-mounted material handling equipment. These wheels come in a range of configurations, encompassing single-flange wheels, double-flange wheels, and other specialized nonstandard designs. The materials used in the construction of these wheels include 2CrMo4, ZG340-640, ZG50SiMn, 65Mn, 42Cr, etc., and more.
We employ diverse techniques tailored to the specific materials, expertly controlling the quenching and tempering temperatures to achieve the desired metallographic structure and optimal mechanical properties.
We employ three distinct heat treatment methods customized to specific requirements: Firstly, hardening and tempering yield a wheel surface hardness of HB300-380, primarily suitable for standard crane products. Secondly, surface medium frequency quenching and tempering result in a wheel surface hardness of HB300-380 or HRC50-56, ideal for products requiring low wheel center hardness and high wheel surface hardness, and when complete heat treatment is not feasible. Lastly, hardening and tempering lead to a wheel surface hardness of up to HRC50-56. Wheel surface hardness diminishes with depth due to material variations, with forged alloy steel wheels featuring a hardening layer depth of up to 15mm, ensuring minimal hardness attenuation. This method finds extensive use in applications such as port cranes and bucket-wheel excavators.
