Metallurgy of Rolling mill Rolls – IspatGuru

Metallurgy of Rolling mill Rolls Rolls are implements or tools used in rolling mills to reduce the cross section of the material being rolled. They are highly stressed tools and are subject to wear. They are needed both for the rolling of sectional as well as flat products.Physical Metallurgy of a HSS Material for Hot Rolling Mill,,Rolls having such tough carbides combined with suitable amounts of Cr and Mo are expected to provide higher wear resistance than ordinary HSS rolls (4).On the other hand, the amount of M 2 C carbides need to be limited to prevent the forming of networks of brittle particles which could increase sensitivity to crack propagation and reduce spalling resistance in case of rolling mill incidents (5,PHYSICAL METALLURGY OF A HSS MATERIAL FOR HOT ROLLING,PHYSICAL METALLURGY OF A HSS MATERIAL FOR HOT ROLLING MILL ROLLS Jacqueline LECOMTE-BECKERS 1 Jerome TCHOUFANG TCHUINDJANG 1 Eric PIRARD 2 Jean-Pierre BREYER 3 ABSTRACT High Speed Steel (HSS) cast,

Physical metallurgy of a HSS material for hot rolling mill,

HSS rolls are advisable in Hot Rolling mill because they keep homogeneous thickness and uniform surface on rolled plates. This kind of application leads to enhance surface quality of rolled plates,Types of Rolling Mills | Metallurgy,Cluster mill is generally used in cold-rolling operation. The arrangement of cluster mill is shown in Fig. 2.9 (d). Type # 5. Multi-High Rolling Mill: The multi-high rolling mill consists of two small diameter working rolls, a row of intermediate driving rolls, and a raw of backup rolls. This arrangement involves a cluster of either 12 or 20,Rolling (metalworking) - Wikipedia,In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallizationtemperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature…

In the first group of stands the bloom is rolled into billets of 120 x 120 mm 2 cross section and in the second group it is further rolled to 55 x 55 mm 2.There is arrangement of transfer tables to take out the bigger sections from the first group of stands without going through the second group.GENERAL ASPECTS OF ROLL COOLING FOR HOT & COLD,rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills. Cooling and lubricating is furthermore essential for the plateout for,

Mills for Reducing Tube Thickness and Sizing | Metallurgy

After rolling the tube to desired thickness it is transferred to reeling mill. The reeling stand (Fig. 12.23) which consists of two barrel shaped rolls, also roll the tube on a mandrel. The modern reelers are more powerful and the take part of load of plug mills. The thickness decreases a bit while diameter may slightly increase. The tube gets more rounded and smoothened. After this the tube goes through sizing millPhysical Metallurgy of a HSS Material for Hot Rolling,Rolls having such tough carbides combined with suitable amounts of Cr and Mo are expected to provide higher wear resistance than ordinary HSS rolls (4).On the other hand, the amount of M 2 C carbides need to be limited to prevent the forming of networks of brittle particles which could increase sensitivity to crack propagation and reduce spalling resistance in case of rolling mill incidents (5,Physical metallurgy of a HSS material for hot rolling,HSS rolls are advisable in Hot Rolling mill because they keep homogeneous thickness and uniform surface on rolled plates.
