Alloy Steel Rolls Suppliers and Manufacturers

Alloyed rolls are special steels alloyed with nickel, chromium & molybdenum which is used in breakdown, roughing & intermediate mills for finishing of heavy sections. These rolls are statically casted and undergo a three stage high temperature heat treatment comprising of annealing, normalizing & tempering rotation. The rolls are available in a wide variety of composition & properties to suit specific application. The matrix structure is pearlitic or bainitic depending on the alloy content. Changing the carbide distribution obtained through controlled chemical composition varies the hardness. It's used in finishing rolls for sheet, plate and strip mills.Intermediate and finishing rolls for small section, bar and wire rod mills. Also used as cold mill rolls for ferrous and non-ferrous sheets. Applications Rolling mills TMT type rolling mills

Alloy steel formed by adding some alloy elements into the common carbon steel, through heat-treatment process, the good performance of wear-resistance and toughness can be achieved. It is widely used for backup/roughing roll for plate/strip mill and backup roll for leveling mill, Roughing roll for plate/section/bar & wire-rod mill; Break-down roll for rail beam/universal section mill; Descaling/roughing/backup/vertical roll for strip mill.

Alloy cast steel roll is manufactured with high quality steel molten by arc furnace, due to the advanced casting and thermal treatment technique, such roll is of very high intensity. Owing to its excellent performances of anti-heat crack, tenacity and wear-resistance, it is appropriate to be used for rough and intermediate shape steel rolling machine , heat rolling strip steel rough rolling machine stand and used as back-up-roll for heat rolling strip steel. Its metallographic structure is made of pearlite or temper sorbite. Metal pallet, wooden pallet box.

Furnace rolls made by HEXIN ;, the rolls are normally for heat treatment furnace,continuous furnace, roller hearth furnace, walking beam furnace, CAL(continuous annealing line),CGL(continuous galvanizing line), to provide support for the slab or sheets or strips so that they could move through the furnace as requested, with operating temperatures up to ;C. our main products includes: sink rolls and arms for galvanizing lines, immersed and stabilizing rolls and arms, defector rolls, hot bridle rolls, water cooled hearth rolls, guide rollers, bushes and sleeves for continuous galvanizing lines. Owing to some small foundries or trading companies exporting less-quality rolls, some international steel mills might have bad impression with the casting rolls from China, actually, there are indeed some bad players who focus only on profit margin, they quote super lower price to get the order on one way, after they getting the order, they will use cheaper dirty raw materials to cut down the cost, finally they will get bad quality , like cracks, shorter life of the rolls.But from HEXIN, you will never get bad quality castings nor rolls, radiant tubes, because we believe to do the BEST or nothing, we will never offer less-quality castings, we care about the customers benefits and the long building reputation of us.( sink rolls, immersed and stabilizing rolls for furnaces.) The HEXIN& furnace rollers are made from high nickel and high chrome heat-resistant alloys, cobalt base alloys, like HU, HT, HK, HP, HW, 24/24NbTiZr, 50Cr/50Ni (2.4813), 1.4865, 1.4849, 1.4848, 1.4410, 1.4059, 1.4841, 1.4845, 1.4852, 2.4879 or as per customer's requirements, by spun casting barrel tube and static cones and forged shafts. The roller sizes range from OD.60MM to OD.1600MM(2.36 to 63inch), according to customer design. To guarantee the perfect performance of each roller we made, we control the quality from raw material inspect PMI ,chemical composition controlled by Spectrometer, pressure testing for the barrel tube, eddy current test, CNC machining, grinding the surface to Ra.0.1 max.,dye penetrant test, dynamic balancing, static balancing,etc., We take care of each step of each components of the furnace, and we also care about the safety delivery of the rollers, so we have our own designed package to guarantee the rollers can reach you with perfect quality through the long way of shipping. You can definitely trust us on rollers. (sink rolls, immersed and stabilizing rolls for furnaces.) http://www.hexinmachinery.com/?p=45&a=view&r=5

Definite chilled iron rolls have a high-hardness layer of white cast iron at the surface. These rolls have the advantage of selecting the harder best performing material on the working surface, which is primarily a Cr-Ni-Mo alloyed chill cast iron & a relatively softer material inside. White chill iron is less soft,strong and incapable of withstanding high dynamic stresses but owing to its greater hardness , has enough strength and better wear resistance against thermal shock occurring at the time of accident in the rolling operation compared to other chilled rolls. These rolls have high compressive strength.It retains a fair proportion of its strength at elevated temperature, for example, in hot rolling . Chilled to graphite being smoother, the hardness associated with the definite chilled structure allows deeper grooving. A very fine surface finish is required , rolls for hoop and skelp mills must be chosen with special attention to strength and hardness so the rolls will match the roughing , intermediate and finishing stands. The rolls are double poured duplex rolls and are manufactured by the advance centrifugal process. These make excellent work rolls for two, three and four-high mills, turning out of high grade ferrous and non-ferrous sheet and strip or section. High Alloy Clear Chill Rolls have proved well suited for the finishing stand of rod and light section mills, for continuous small and medium hot strip mills, and for strip mills of older design. These rolls are manufactured for section mills producing rounds, squares, flats, Hexagon, Gate Channel as well as mills producing Tor steel and Tmt bars.
