Product Name: Continuous Annealing Furnace Tool- Bottom Furnace Roller Model NO.: as the drawing Application: metal Processing Machinery Parts Material: Alloy Customized: Customized Standard: DIN, ASTM, GB Certification: CE, ISO9001 Condition: New Application Range: Heating Treatment, Trademark: FANGLE Transport Package: Seaworthy Package Specification: as the requirement Origin: China Product Description Continuous annealing furnace tool- bottom furnace rollerDescriptionThe hearthroll,also called furnace rollis the key equipment for continuous annealingfurnace. The continuous heat treatment furnace with bottom rollers is often used for annealing, normalizing, quenching and tempering of steel plate, steel tube, section steel and wire.Furnace bottom rolls made from small diameter of 60 mm - 2000 mm Φ various national standard material of heat-resisting alloy steel hollow bottom roller.The temperature of furnace varies from 850ºC to 1200ºC, and the material used is also different.Suitable for annealing treatment of general carbon pipe, oil well pipe, stainless steel pipe and steel strip.In particular, it is suitable for continuous annealing treatment line with higher reliability.ParameterMaterialswear resistant, heat resistant,corrosion resistant alloy steel, such as ZG35Cr24Ni7SiNRe,ZG40Cr25Ni20Si2, 1Cr18Ni9, ZGCr25Ni35Nb, ZGCr28Ni48W5 HK40, HT, HU, HH, 22H, 304,Super 22H, HP-Nb, More1, More2, 1.4848, 1.4855, 1.4852, 2.4879, 1.4460,1.4462, S32205, S32750, etc.ProcessLost wax casting: Mould making- Shell making- Pouring-Sand (glass ball) blasting-CNC machining- Inspection- Assembly.specificationAs per cusomers' requirementsPropertyExcellent Corrosion Resisitance, High Temperature Resistance, Wear resistance, Good surface, Hight tolerance, Fast delivery, etc.TestEach piece has to go through our strict inspection, VT, PT, UT, LT, RT, MT,or according to customers' requirementsApplicationRefinery, Petrochemical and Fertilizer:Ammonia production,Convection furnaces,Direct Reduction of Iron (DRI),Ethylene pyrolysis,Hydrogen production,Methanol production,Steam reformers, Annealing furnace, heating furnace,cracking furnaceWorking temperaturedepending on the materials (max 1350°C)Manufacturing process of furnace roll:1. Centrifugal casting of roll body.2, the shaft head adopts lower than the roll profile processing.3. The shaft head is combined with the roll body by heat fitting, and welded with welding material of the same material of the roll body.Customer Visit
