Adamite Roll Introduction The semi-steel adamite roll is casted as a whole and there is no weak interface in compound casting roll, thus it has a better capacity, strength and toughness than cast iron roll. This kind of mill rolls can be used as work roll, back-up roll and vertical roll for large-class and medium-class rough rolling mill and intermediate rolling mill of section steel, wire rod, rail beams, steel billet, hot rolling steel strip. Most of the adamite steel rolls are produced by the static integral casting method. It must be subjected to high-temperature diffusion annealing. Generally, adamite rolls for steel rolling mills are required to control the total amount of non-metallic inclusions below 0.05%. The centrifugal composite semi-steel back-up rolls are made of adamite steel material, the body and neck of the rolls are made of nodular cast iron, and they have been successfully used in hot-rolled strip steel finishing mill.

Forged steel rolls have toughness, surface hardness uniformity and fatigue resistance and widely used to the cold rolling mill. The mill rolls are made from steel ingots by forging. Forging can solve metallurgical defects such as loose and shrinkage holes in the ingot, and crush the coarse cast structure to obtain a high-quality roll with dense structure and uniform composition. The production process of forged roll includes smelting, ingot casting, forging, post-forging heat treatment, rough processing, final heat treatment and finishing. The rolls are heat-treated differently depending on the material and application. They are mainly used as strip rolling mill work roll and backup roll, H-type steel universal–shaft, High-speed roll(HSS roll), Cr4 steel backup roll, Cr5 forged steel roll, 86CrMoV7 forged steel roll, 42CrMo forged steel roll, MC2, MC3, MC5, MC6 forged steel roll, etc.

The alloy ductile cast iron roll is made of acicular nodular cast iron mixing with nickel, chromium, molybdenum. It can be used in various blanking rolling mills for section steel, bar, wire rod and narrow strip, roughing mills, work roll for seamless steel tube, intermediate stand and finishing stand for section steel, bar, wire rod and narrow strip and rolling mills before finishing rolling for various sections and plate steels. The finished spheroidal graphite iron roll can also be used in the case of a low load. When the finished roll is subjected to a heavy load, it is preferable to use as a nodular cast iron chill roll with high strength and wear resistance. The TINVO mill rolls conform to the standards of ISO, GB, ASTM, DIN, and JIS, high quality with the best price guaranteed Alloy spheroidal graphite iron roll has a lot of usage following as: Blooming roll rack of rolling mills for section steel, bar, wire rod and narrow strip, Rolling mill work roll for seamless steel tube

Chilled Cast Iron Roll Introduction There is no free graphite in the working layer of alloy chilled cast iron roll, it is featured as high hardness, good wear-resistance, micro metallographic micro-structure is fine pearlite and carbides. Application The finishing mill for section steel, wire rod, strip, thin plate and bar; The pre-finishing stands of high speed wire; With roll ring of stretch reducing mill for seamless steel tube.

The cast iron roll is produced by a horizontal centrifugal casting process with high-speed steel as the work layer and nodular iron as the core. The material of centrifugal casting iron roll contains plenty of alloying elements such as Mo, Ni, Cr, etc. The high hardened eutectic carbides & second carbides, evenly distributed in tempered martensitic matrix, make the wear and thermal cracking resistance very excellent. Besides, the resistance to surface roughing is also good. In a condition of hot rolling, the contact points between steel strip and the work rolls can form a thin adherent oxide film on the roll surface, which plays a good role in the wear features and the quality of the strip surface. The main application is as a working roll for hot-rolled strip leveling rack and rack of high-speed wire mill.
