What is a casting roll and what are the types of casting roll?

The roll is a tool to produce plastic deformation of the metal, and is an important consuming part to determine the efficiency and quality of the mill。 Roll types can be divided into casting roll and forging roll according to the forming method; According to the process method, it is divided into integral roll, metallurgical compound roll and combination roll. Integral rolls are divided into integral…

Pearlitic nodular cast iron rolls

The shell material of pearlitic nodular cast iron rolls consists of spherical graphite and carbides in a pearlitic matrix. We can obtain Chromium alloyed pearlitic nodular iron rolls if we control suitable Chromium content.Rolls of this type which are alloyed with Chromium to achieve a deeper penetration of carbides is belong to pearlitic nodular iron rolls.This kind of rolls has alower hardnessdrop than the standard nodular…

Forging

Introduction: Forging: is the process of shaping heated metal by the application of sudden blows (i.e., hammer forging) or steady pressure (i.e., press forging) and makes use of the characteristic of plasticity of the material. A metal such as steel can be shaped in a cold state but the application of heat lowers the yield point and makes permanent deformation easier. Forging may be done by…
