The carbon content of the alloy adamite roll is usually between 1.2-2.3%, the rest contain Cr, Ni, Mo and other alloy elements. Through a special heat treatment process, compared with alloy cast steel roll it has a good abrasion resistance; as well as compared with cast iron roll it has a good strength and toughness.
Alloy Cast Steel Roll is made of eutectoid steel and hypereutectoid steel. Alloy content greater than 0.8%, carbon content 0.4~1.3, Cr, Ni, Mo, V is added, matrix structure goes through heat treatment of normalizing and tempering, becoming sorbite and tempered sorbite.
Alloy cast steel roll
There is no free graphite in the working layer of alloy chill cast iron roll, it is featured as high hardness, good wear-resistance, micro metallographic micro-structure is fine pearlite and carbides. Standard includes ISO, GB, ASTM, DIN, JIS. OEM and ODM is available

Alloy forging steel roll
The alloy infinite chilled cast iron roll is a kind of centrifugal composite spin-cast iron roll, it has double chemical, the outside has a high tensile strength and the inside is a lower one, the drop of the hardness is lower.It is usually used as work roll for the finishing mill to roll the final material, to roll the angles, bars, flats and so on.
Alloy infinite chilled cast iron roll
The alloy ductile iron roll is made of acicular nodular cast iron mixing with nickel, chromium, molybdenum through a special heat treatment to obtain the pearlite alloy ductile iron roll. This pearlitic nodular cast iron roll has good strength, high temperature performance and anti-accident performance, small hardness differential on the working layer.
Alloy spheroidal graphite iron roll
The backup roll is a roll that supports the work roll, and contacts the rolled parts through work roll so as to reduce the diameter of work roll and enhance the rigidity of work roll.
Bainite ductile cast iron roll is made of Ni, Mn, CrH, Mo, etc. It has acicular structure(Bainite and a few Martensite) and would be higher strength and better toughness than pearlite ductile iron roller, besides, the wear resistance is improved much obviously. This kind of roller can be made by means of static casting and centrifugal casting.
