Hot Working Die Steel Rolls are formed in the high temperature state It has high thermal strength good thermal stability excellent resistance to wear and thermal fatigue as well as sound temper stability This type of rolls can deliver a much longer service life when used for blooming of large section mills
In hot rolling mills premature failure of rolls is a major concern as it adversely affects the mill operation as well as production Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls

Rolling mill refers to the equipment that completes the whole process of rolling material production including main equipment auxiliary equipment lifting and transportation equipment and auxiliary equipment However the so-called rolling mills are often referred to only as the main equipment
Hot Rolled Steel is manufactured using a mill process which involves rolling the steel at a high temperature (above the steel's recrystallization temperature) While the steel is above the recrystallization temperature it can be shaped and formed easily With Hot Rolled Steel the starting material is usually large pieces of metal such as slabs blooms and billets Benefits Lower Cost
Typical upgrades to hot mill stands include the addition of roll bending for profile and shape control as well as the installation of hydraulic roll force systems for automatic gauge control Customers are also looking to see production improvements by eliminating mill down time through shorter roll changes This may be accomplished by modernizing the mill window and incorporating quick work
