Best Quality Casting and Forging Steel Forging Pinion, Gear Gearbox, Transmission Gearbox

Best Quality Alloy Steel Large Forging Pinion GearCITICHL Pinion Gear invested in significant resources and achieved many innovations with pinions. The right combination of material, hardness and finishing between pinion and gear is crucial for a long lifetime of the installed equipment. We design and manufacture pinions to match every customers need, no matter how unique the situation might be.   Casting & forging abilityCITICHL is the casting & forging center in central-south China, possessing 50t electric arc furnace, 60t LF ladle refining furnace, and 60t VD/VOD refining furnace, etc. We can pour 350t liquid steel one time and yields more than 200,000t of  high quality liquid steel and can produce the high quality steel of more than 260 steel grades such as carbon steel, structural alloy steel and the structural steel, refractory steel and stainless steel of special requirement. The maximum weight of casting, gray casting, graphite cast iron and non-ferrous casting is 200t, 30t, 20t and 205t separately.  The company is the forging center in central-south China. It is very powerful in forging. The single free forging is 100t(max weight). We can roll rings of different sections of carbon steel, alloy steel, high temperature alloy and non-ferrous alloys such as copper alloy, aluminum alloy and titanium alloy. The maximum diameter is 5.5m and single piece of the forging weighs 10t. We have 8400t, 3150t, 1600t, water press and RAW 200/160-5000/750 large-size ring mill of high precision in Asia made in WAGNER, Germany. Heat treatment abilityThe company is the heat treatment base in national machinery trade in central and south China, possessing Φ3×1.6m carburizing furnace, Φ2.3×17m,Φ2.3×9.5m shaft furnace, 8.5×13m,5×15m,6×14.5m,4.5×18m automatic controlled car type heat treatment furnace group. We can supply the quenched and tempered part over 45t, the carburizedand quenched gear and pinion below 20t, shaft≤5.7m in length and the induced girth ring diameter≤5mOur pinion gears FeaturesPinion design: bored solid on shaft / integral self aligned spur, helical or double helicalforged alloyed steelSpur, helical or double helicalThree different designs:Fabricated steel - forged ring - rolled plateStandards/Certificates :• UNI EN ISO • AWS • ASTM • ASME • DIN  Pinion gear cutting machinesΦ16m CNC hobbing MachineΦ12m Gear cutting machine (Switzerland)Φ10m hobbing machine (Germany)Φ4m CNC high speed hobbing machine (Germany)Φ1.6m Horizontal CNC hobbing machine (Germany)Φ5m CNC profile gear grinding machine (Germany)Φ2.8m CNC Profile gear grinding machine (Germany)Φ1.25m CNC Profile gear grinding machine (Germany)Φ1m CNC Profile gear grinding machine (Germany)Inspection and Test Outline of Girth Gear:No.ItemInspection AreaAcceptance CriteriaInspection StageCertificates1Chemical CompositionSampleMaterial RequirementWhen SmeltingAfter Heat TreatmentChemical Composition Report2Mechanical PropertiesSample(Test Bar on the Gear Body)Technical RequirementAfter Heat TreatmentMechanical Properties Report3Heat TreatmentWhole BodyManufacturing StandardDuring Heat TreatmentHeat Treatment ReportCurves of Heat Treatment4Hardness TestTooth Surface, 3 Points Per 90°Technical RequirementAfter Heat TreatmentHardness Teat ReportAfter Semi Finish Machining5Dimension InspectionWhole BodyDrawingAfter Semi Finish  MachiningDimension Inspection ReportFinish Machining6Magnetic Power Test (MT)Tooth SurfaceAgreed StandardAfter Finish Gear HobbingMT  Report7UTSpokes PartsAgreed StandardAfter Rough MachiningUT ReportAfter WeldedAfter Semi Finish Machining8PTDefect AreaNo Defect IndicatedAfter DiggingAfter WeldedPT Record9Mark InspectionWhole BodyManufacturing StandardFinal InspectionPictures10Appearance InspectionWhole BodyCIC's RequirementBefore Packing(Final Inspection) 11Anti-rust InspectionWhole BodyAgreed Anti-rust AgentBefore PackingPictures 12Packing InspectionWhole BodyAgreed Packing FormDuring PackingPicturesFacilities For Manufacturing Gear ring:No.ItemDescription1Smelting & Casting Capability 40t ,50t, 80t Series AC Electric Arc Furnace2×150t, 60t LF Ladle Refining Furnace150t, 60t Series VD/VOD Furnace20×18m Large Pouring FacilityWe can pour 900t refining liquid steel one time, and achieve vacuum poured 600t steel ingots.We can produce the high quality steel of more than 260 steel grades as carbon steel,structural alloy steel and the structural steel, refractory steel and stainless steel of special requirement. The maximum weight of casting steel, gray casting, graphite cast iron and non-ferrous casting is 600t, 200t, 150t and 20t separately.2Forging Capability The only one in the word, the most technologically advanced and the largest specification18500t Oil Press, equipped with 750t.m forging operation machine8400t Water Press3150t Water Press1600t Water PressΦ5m High Precision Ring Mill ( WAGNER,Germany)Φ12m High Precision Ring MillWe can roll rings of different sections of carbon steel, alloy steel, high temperature alloy steel and
