Product Description

Rollers, also called rollers, refer to the collective name of cylindrical parts that can roll on the machine
After about 15 days of use, the Roller collapsed at about 260 mm from the shaft head, and the noise during the collapse was very loud, and the broken shaft head collapsed nearly 1 m. The roller shaft belongs to a variable section shaft, the maximum diameter is 545mm, the total length is 2 296 mm, the material grade is 40Cr, and it has undergone forging, rough turning, quenching and tempering heat treatment and fine turning.
The roller fracture mode is hydrogen embrittlement cleavage fracture, that is, hydrogen embrittlement.
Due to the failure to effectively remove hydrogen during the roller smelting process, the local hydrogen content is high, and the residual stress that can induce hydrogen embrittlement is generated in the roller tempering and tempering Heat Treatment Process, resulting in the accumulation and expansion of the residual hydrogen in the roller shaft and causing delayed fracture
