leadar roll - iron roll products,iron, or nodular iron, is a generic description of a common industry grade of cast ductile iron or spheroidal graphite cast iron. nodular iron materials have a toughness advantage over grain or chill iron grades. the spheroidal shape of the graphite phase makes these rolls less sensitive to impact. consequently, softer nodular iron is applied in heavy breakdown services while the harder grades are.china cast iron roll manufacturers,bainitic nodular cast iron roll. juncheng is manufacture and supplier mill rolls which are used in iron and steel products making. our rolls are mainly used by long product(bar,wire, rail, h-beam and heavy section steel) and flat product(hsm, csp and narrow strip steel) mills for both hot and cold rolling..alloy ductile cast iron rolls with good strength | tinvo,alloy ductile iron roll. 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.

nodular acicular cast iron rolls. the strength of the spheroidal graphite(sg) or nodular cast iron is a result of a change in morphoglgy of flake graphite into graphite spheroids. the lower surface area to volume of the spheroids increases its fracture toughness and hence reduces crack propagation.

nodular pearlitic cast iron roll. pearlitic rolls are composed by nodular graphite and carbides arranged in a pearlitic matrix. it's properties are similar to indefinite chill except that the graphite structure is changed from flake to spheroidal forms. pearlitic rolls will have higher strength than indefinite chill.
bainitic and bainitic / martensitic nodular iron are nodular grades alloyed with cr, ni, and mo with higher cr and ni contents. compared to pearlitic irons, acicular irons show higher strength, toughness and wear resistance. the rolls can be cast static or spun cast depending of the size of the working layer and the mill conditions. application.

the high-cr cast iron rolls are mase by centrifugal casting process,the working layer contains 12~22% chromium,through rational chemical composition allocations and different heat treatments,the matrix can be controlled as sorbite,troosite,bainite or martensite and certain kinds of carbides,such as cr7,c3 eutectic carbites,cr23c6 second carbites,mo2c carbites etc.according to different purpose
bainitic nodular cast iron roll. bainitic nodular cast iron roll is made of ni, mn, crh, mo, etc. it has an acicular structure and would be higher strength and better toughness than pearlite iron. due to the high alloy content and high casting stress, the acicular bainite ductile iron roll can obtain the ideal comprehensive performance by a centrifugal composite casting process.
pearlitic nodular cast iron rolls. pearlitic and pearlitic / sorbitic nodular iron are nodular grades alloyed with cr, ni, and mo with ni ranging between 1.50 % in the softer grades and 4 % in the harder grades. the right balance of si and cr will help to develop the adequate hardness level. the rolls can be cast static or spun cast depending of the size of the working layer and the mill conditions.
