As a joint owner of the South Korean machine building plant BUKANG (Incheon city) that was founded in 1986 and currently is a leading manufacturer in the South Korea specializing in production of interchanging equipment and spare parts for various metallurgical units, manufacturing and engineering company ENCE offers rolls of rolling mills (mill rolls).
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.

932 Bronze is sold with an as cast oversized surface. The standard material for light duty applications, this bronze is hard, strong, resistant to wear, and easily machined. Typically used in bushings, thrust washers, bearings, pumps, and valve components. Due to the cast finish, this alloy is not normally used for architectural purposes.
Hard industrial chrome is a porous coating which contains microscopic fissures due to the way in which chrome is applied to the base metal. While chrome of 0.005″ -0.010″ thick will provide optimum protection against wear, over time, a corrosive environment will break down the chrome before its typical wear life has been realized.
This is accomplished by heating annealed material to a much higher temperature (1950° F/1065°) and quenching as rapidly as possible. This is a hardening treatment, not annealing. To improve toughness, these alloys are then tempered by re-heating in the range of 300° - 1000° F (150° - 530° C).
As in forging, the rollers create friction at the point of contact with the sample, minimizing the ability of the metal to move at that point. ... Do not roll any hard and brittle materials like steel or oxidized metal. Remove borax residues before rolling stock through the mill. Dry material well before rolling it. ... Many mills allow the two ...
SAE AISI 4140 Alloy Steel. SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature. 4140 Steel Uses. AISI SAE 4140 alloy steel can be made into round steel bar, flat & square steel bar, steel ...

Jan 23, 2020· Once placed in the ring mill, the workpiece is rotated by an idler roll while it applies pressure to the ring's inside part. At the same time, the driver roll is used to apply pressure to the outside part of the ring. During the process, the ring's diameter increases while the material flattens and two axial rolls control the ring's height.
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die.Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working).For the latter two, the metal is heated, usually ...
Dec 13, 2016· What Is Chromoly Steel? Chromoly steel is a type of low alloy steel that gets its name from a combination of the words "chromium" and "molybdenum" – two of the major alloying elements. Chromoly steel is often used when more strength is required than that of mild carbon steel, though it often comes at an increase in cost.
Producing forgings to recognized material standards is a quality benchmark of All Metals & Forge Group, an ISO9001-2008:AS 9100:2009 Rev C manufacturer. Alloy Steel Forgings These represent a range of engineering alloys capable of being heat treated to a very wide range of mechanical properties.

The Difference Between Casting & Forging. Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold or vessel to create a desired shape. Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state.
