forging work roll

Ever wonder how strong metal parts are made with minimal waste? The roll forging process is key. It shapes metals efficiently while enhancing strength.This process differs from traditional forging by using rolling to form parts with precise grain flow. It’s vital for modern manufacturing.

The fracture of the 9Cr2Mo steel cold rolling roll is classified as hydrogen embrittlement fracture, with the crack initiation site located at the circular spots inside the roll where hydrogen accumulates. High hydrogen content and large quenching stress caused by delayed tempering are the main causes of hydrogen embrittlement fracture of the roll, while severe dendrite segregation and abundant inclusions accelerate the fracture. The recommendations are as follows:① Improve metallurgical quality to reduce the content of inclusions and the degree of segregation in the steel;② Increase the forging ratio to avoid dendrite segregation in the material;③ Prolong the hydrogen diffusion time to reduce the hydrogen content of the roll;④ Conduct tempering in a timely manner to reduce the quenching stress of the cold rolling roll.

Forged steel cold rolling rolls commonly use electric slag steel to manufacture roll blanks; Steel ingots are usually treated with high-temperature diffusion to improve the uniformity of the chemical composition of the rolling billet; The roller blank is deformed by forging, and the material has good density; After forging the roll blank, normalizing treatment is carried out to eliminate secondary network carbides, and spheroidization annealing treatment is performed to prepare the microstructure for the subsequent quenching and tempering treatment; Perform hydrogen expansion annealing to prevent the formation of white spots.

Industrial engineering sits at a unique crossroads today. Material science constantly drives structural innovation. Simultaneously, procurement teams seek reliable, cost-effective scaling solutions. Bridging this critical gap requires high-performance components capable of enduring extreme-stress en
