Forging Roll Suppliers and Manufacturers

Forging is a process in which the casted ingot is heated in the furnace & then material is hammered according to the customers sizes & requirements, thereafter heat treatment is done in normalizing/annealing furnace. Forged rolls are manufactured from carbon steel, alloys steel & stainless steel, these rolls are available in primarily in forged m.s. rolls , forged en-8 rolls , forged en-9 rolls, forgeden-19 rolls, forged en-24 rolls , forged en-31 rolls , forged en-42 rolls forged class 2 & forged class 3 etcetera, Our forged rolls are available with groove, bearing sizes, ready to use conditions or in semi-finished or in black forged condition, apart from rolls we offer forged product range of forged spindles, forged rings, forged shafts, forged blanks, forged cranks, forged pinion gears, flanges, forged wheels & other specially ordered products, all forged products are dispatched with essential certification, addition to that we also offer ultrasonically tested forgings for variety of applications.

Roll produced by forging steel ingot. Forging can forge the metallurgical defects such as porosity and shrinkage cavity in the ingot, break the coarse casting structure, and obtain high-quality rolls with dense structure and uniform composition. Forged steel rolls have better strength and toughness, surface hardness uniformity and fatigue resistance than similar cast rolls. (Table 1) in order to meet the specific requirements of different rolling mills and rolling conditions, different alloy elements can be added to the roll steel to improve the roll performance. A certain amount of carbon and alloy elements have the following different effects on the structure and properties of forged steel rolls: carbon can increase the hardness and strength of rolls, reduce plasticity and improve wear resistance; Manganese can increase hardenability and strength; Silicon deoxidizes and improves strength; Chromium can increase hardenability, strength and wear resistance; Molybdenum can increase hardenability, strength and thermal hardness; Vanadium can control the grain size of steel and increase the strength. See Table 2 for the main chemical composition of common forged steel hot rolls and backup rolls.

Manual & auto stock - forging ring rolling.

ZGD Automatic Forging Roll with manipulator are continually optimized and improved products on the basis of EUMUCO technology; With the improvement of process and electric control technology, the application and reliability get large improvement; With the forming rolling, performing rolling processes, die and production line supplied by CFM, the forging roll can be applied in automobile tractor energy and hand-tooling industries. Dozens of production lines for manufacturing automotive front axle, connecting rod, steering knuckle crankshaft and turbine blade achieved enormous economic and social benefits.

It is controlled by plc, man-machine interface, the state of all the motion can be set and adjusted by touch screen and with fault automatic diagnosis, alarm and indication. With center distance eccentric adjusting mechanism and eliminate the backlash in main gear circular tooth mechanism, which make the structure compact and arrangement reasonable. With automatic lubrication device. The hydraulic oil tank is with cooling and heating device, temperature and level alarm. Both pneumatic friction clutch and brake have the functions of single-action, serial action and inching etc. With the features of slow hydraulic start and rapid rolling. The work-piece is input automatically to realize automatic forging, which not only improve the production efficiency and quality, but also reduce the labor intensity. The relevant movement between the forging rolls and mechanical arm is controlled by plc. For the small size forging rolls, the lateral moving of mechanical arm clamp can be driven by the servo motor and the ball screw structure. Servo motor driving mechanism and die constant temperature heating mechanism are adopted for aluminum alloy rolling.

Forged steel rolls To forge ingot castings into work rolls, intermediate rolls and backup rolls with compact structure and homogeneous compositions. As a result, forged rolls have better toughness, more uniform surface hardness and better fatigue resistance than cast rolls with the same type.Forged rolls can be applied to hot rolling and cold rolling. Application for hot rolling: Hot-rolling blooming and rough rolling for profile steel Materials:55Mn2,55Cr,60CrMnMo,60SiMnM,etc.As per buyer's requirements. Application for cold rolling: Widely used as work rolls for cold-rolled sheet. Materials: 9Cr,9Cr2,9CrV,8CrMoV,8Cr2MoV,92Cr2Mo,92Cr2MoV,9Cr3Mo,8Cr3MoV,8Cr5MoV,etc. As per buyer's requirements.
