QU Crane rail
QU crane rails that meet GB standards have good cold bending performance and are easy to install and maintain on site through optimized chemical composition ratios and rolling processes.
QU70, QU80, QU100, QU120 GB crane rails are usually produced using a special rolling process. First, the steel billet that meets the requirements is heated to a suitable temperature, and then rolled through a series of rolling mills to gradually roll the steel billet into the required rail shape and size. During the rolling process, parameters such as rolling speed, temperature, and reduction need to be precisely controlled to ensure the dimensional accuracy and surface quality of the rail.
After rolling, the rails also need to be heat treated, such as quenching and tempering, to improve the mechanical properties of the rails, such as strength, hardness, and wear resistance. After heat treatment, the internal structure of the rails is optimized, and they can better withstand various loads during crane operation.
Finally, the rails are surface treated, such as shot peening, to improve the surface finish and residual compressive stress of the rails, and enhance the fatigue resistance and corrosion resistance of the rails.
