Heavy Load Capacity Built - Up Sleeved Backup Rolls High Precision To 0.01mm
High Precision to 0.01mm Heavy Load Capacity Built-up Sleeved Backup Rolls
The first roll for hot-rolling mills were produced from ingots weighing up to 40 tons at Uralmashplant in 1934. The plant began producing large ingots, weighing 60 tons and more, in 1935-1936, which allowed to manufacture large backup rolls for rolling mills.
Because of exceptionally high requirements to the quality of metal used for production of cold mill rolls, re-tooling and modernization of the production plant were carried out by the 1940. Since then, rolls for cold-rolling mills have become an integral part of Uralmashplant's assortment.
Uralmashplant is rated among the leaders at the world's roll market due to renovated production capacities.
Based on the manufacturing facilities, the plant has mastered production of a new type of rolls with 3 to 5 percent Cr content, as well as higher content of alloying elements, which allows to make the service life of rolls 1.5 to 2 times longer.
