Abstract The premature failure of two forged and induction hardened low alloy steel work rolls used for cold rolling of high and medium carbon steel was investigated. Microhardness profiles indicated that the values of the effective induction hardening depth for both rolls are below the user's requirement. Tensile testing results of the core of the rolls indicated that the tensile and .

Some users have found that the surface roughness of the work rolls with 5% Cr forged steel changed rapidly when rolling high-grade car plates. At this time, forged semi-high-speed steel materials can be used. But because the forged semi-high-speed steel materials are expensive, you must compare the performance & price then decide.
Nov 30, 2018· In simple words, when a hot cooled down steel roll is further compressed between rolls, cold steel rolls are obtained. When perfect dimensions are what you seek for, cold rolling steel is what would fit the requirements. On the contrary, when bar or tubes need to be shaped up, cold drawing is undergone instead of rolling.
The rolls are primarily applied in high speed wire line, Kocks three roll mill, seamless pipe stretch reducing mill, three dimensional rolls for cold-rolled ribbed steel bar, and composite roll for hot-rolled bar screw thread steel etc.
