A Guide to the Types of Forging–Cold Forging and Hot Forging

Hot forging and cold forging are two different metal forming processes that deliver similar results. Forging is the process of deforming metal into a predetermined shape using certain tools and equipment—deformation is accomplished using hot, cold, or even warm forging processes. Ultimately, the ...

Metal Rolling - thelibraryofmanufacturing

Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing ...

MECHANICAL ENGINEERING: HOT WORKING OF METALS

5. In hot working processes, compositional irregularities are ironed out and nonmetallic impurities are broken up into small, relatively harmless fragments, which are uniformly dispersed throughout the metal instead of being concentrated in large stress-raising metal working masses. 6. Hot working such as rolling process refines grain structure.

Rolling (metalworking) - Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

Hot rolling and rolling defects - nptel.ac

1. Hot rolling and rolling defects: 1.1 Front and back tensions: We have seen that the rolling load is dependent on roll diameter, higher the roll dia, higher the roll force. Similarly, smaller reductions requires lower roll force. In order to reduce the roll force, we can reduce roll diameter, or reducing the friction.

Hot-Rolling, Cold-Forming; Extrusion, and Forging ...

If the temperature is above the crystallization temperature of metal, the process is called hot-rolling; otherwise it is called cold-rolling. In hot-rolling, hot-molten steel is passed several times through pairs of rolls to achieve the desired profile. Most structural steel components such as I-Shape, L-Shape, etc. are hot .

There are two types of rolling. With hot rolling, heated metal goes through a rolling machine where it is worked into a sheet or bar. With cold rolling, sheet steel is made thinner at normal temperatures, and its surface is made smooth and uniform. Tsubaki products are used in both hot and cold rolling.

Hot & Cold Working and the Rolling Process - Leong Huat

For hot working processes, large deformation can be successively repeated, as the metal remains soft and ductile. The hardness of the material cannot be controlled after hot rolling and it is a function of chemical composition and the rate of cooling after rolling. The hardness is generally lower than that of cold rolling and the required ...
