TYPES OF FORGING PROCESSESADVANTAGES OF FORGINGSEAMLESS ROLLED RINGSWHAT IS FORGING?FORGING IS A MANUFACTURING PROCESS WHERE METAL ISMODELED BY APPLYING PRESSURE AFTER MAKING IT DUCTILETHROUGH THE APPLICATION OF HEAT.This process directs grain flow in tangential and radial directions, and provides the pieces with the mechanicalproperties such as strength, ductility, and resistance to impact and fatigue.1. Ingot is cut according to thenecessary weight and the presspreforms the cut achievingthe structural and directionalintegrity of the grain.2. The disc is perforated creatinga “doughnut.”3. The “doughnut” enters theroller, where the mandrelexerts pressure against theradial until the desireddiameters are obtained.(The Forging Industry Association)Forging techniques are useful for working metal becausethey enable the desired shape to be given to the steeland also improve its structure, especially becausethey refine its grain size.Forging takes ingot as a raw material, which is subjected to hotdeformation in order to refine the metallurgical structure.No other steel deformation process can equal the capacityof forging to develop an optimal combination of properties.Forging is normally used in components where safety isfundamental, for instance, in planes, cars, tractors, boats,oil drilling equipment, motors and other industrial machinery.OPEN DIE FORGINGThis is the process of free deformation of the material through the use of flat dies. The ingot is manipulatedbetween the dies, which press the piece until it achieves the desired geometry.1. Prior molding toachieve the desireddiameter.2. The work areas aremarked on the piece.3. The markings areforged to the desiredsize.4. The piece is flattenedand rounded for abetter surface finish.POT DIE FORGINGsave in material and machining time by maintaining the properties of the forged material.

ADVANTAGES OF FORGINGTHE FRISA ADVANTAGEStronger componentsForging provides better mechanical properties, ductility and fatigue and impact resistance becausethis process refines and directs the grain flow according to the shape of the piece.Structure of theoriginal grain Final Measurement Excess ( /-) ToleranceRecrystallizationof the grainThrough a minimal use of material excesses, it is possible toguarantee an optimization in costs while providing a piecewith the appropriate tolerances that always guarantee thatthe piece can clean at final measurements.PlasticdeformationGrowth ofnew fine grainThe open die forging process modifies the structure of the crystals.In most cases, the ingots have been pre-worked and thisproduces a “grain flow” with important directional properties:greater mechanical resistance, greater ductility and fatigue andimpact resistance.The forging pieces havea directional grain flow,therefore, their mechanicaland metallurgical propertiesare better than any otherprocess. The structuralintegrity of a forged piececannot be beaten by anyother transformation process,since it removes porosities,gases and internal cavitiesthat could cause unexpectedfaults under stress, fatigueand impact.CastingRange of SteelsAlmost all metals—ferrous and non-ferrous—can be forged. Any kind of steel can be used:carbon, alloy, stainless or superalloy.Significant SavingsForging reduces the weight required tomanufacture the piece, therefore, there is a realand significant cost savings. Also, the pieces haveless excess so they require less machining hoursand less material to be used to clean the piece atthe end.Wide range of shapes and sizesThe design of shapes is so versatile that they can be forgedfrom simple bars and rings to more complex pieces, accordingPlatingForgingPlating machined ringRolled RingsOpen Die Forging315 in maximum outside diameter70 in maximum outside diameter67 in maximum length287 in maximum length40 in maximum wall55,000 lb maximum weight55,000 lb maximum weight*information can vary depending on material and geometryForged ring

Forging is a widely used method of metal forming. There is a free forging (Fig. 1.1, d) and closed die forging (Fig. 1.1, e). During the process of free forging the reduction of the forging piece height is realized
forging process design. Defects can be defined as the imperfections that exceed certain limits. There are many imperfections that can be considered as being defects, ranging from those traceable to the starting materials to those caused by one of the forging processes or by post forging operations.
