Material Selection of Rolling Mill Rolls – Hani Tech
Generally, cast semisteel and highchromium centrifugal composite cast iron are used Highchromium centrifugal composite cast iron has high roll surface wear resistance and thermal crack resistance, and it can suppress roll surface defectThe 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 goodCentrifugal Cast Iron Roll Highspeed Steel Roll TINVORolling mills worldwide have proven that using our cemented carbide composite rolls can increase your rolled tonnage by twenty times versus conventional cast iron rolls The castincarbide (CIC®) concept takes this material a step further, as proven in over 100 hot rolling mills all over the world Explore our rolls solutions for your hot Benefits with Composite RollsNi Cr Mo chilled centrifugal composite cast iron mill roll Tangshan Weilang Trading Co, Ltd US $9003500 / Piece 1 Piece (Min Order) Tags: Cold Roll Stainless Steel Forged Mill Roller Hot Rolling Mill Rolls Pearlitic ductile cast iron rolls and best quality rolling mill rolls OEM Liaoning Mineral Metallurgy Group Co, Ltd US $100020000 / Piece 1 Piece (Min Order) Thus,the high composition cast iron mill rolls, composition cast iron High chromium centrifugal composite cast iron has high wear resistance and hot crack resistance on the roll surface, and can inhibit the roll surface spot defects Finishing work roll (F57): the use of finishing work roll in the final stage of rolling has a very important impact on product quality Roller of Rolling Mill – Hani Tech
Cast Rolls Kolding
As the charge we use roll scraps, scrap steel and quality special pig iron – hard The uptodate furnaces enable production of quality roll alloys Casting: Nowadays, the achieved technology permits casting of single layer, composite static and centrifugal cast and hollow rolls of different qualitiesThe mill roller is mainly composed of a roll body, a roll neck and a shaft head The roll body is the middle part of the roll, which actually participates in the rolling of the metal with a smooth cylindrical or grooved surface There are steel rolls, cast iron rolls, alloy rolls, ceramic rolls, etc, according to the roll Mill Rolls For Different Rolling Processes TINVONodular 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 SG iron is an excellent conductor of heat and Nodular Acicular Cast Iron Rolls HKT INTERNATIONAL GROUP These rolls are manufactured by Centrifugal Casting (CC) method and the roll core is filled with spheroidal graphite cast iron The adequate chemical composition control and proper heat treatment ensures the hardness of roll working layer to reach as high as 8085HSC Uniformly distributed complex carbides of Vanadiumrolls for rolling mill SlideShareConsistency in Centrifugal Casting Products With the flexibility to match your volume requirements, nonstandard sizing specs and valueadded finishing needs, Spuncast provides centrifugal casting products with quality, performance characteristics and ontime delivery you can count on Over 3 Decades of Success in Hydraulic Cylinders Shock absorber cylinders, stabilizers and dumper Products
