Hard chromium plated work rolls (typical plating thickness 4–15 μm) have been used for over 25 years both in tandem and temper/skin-pass rolling mills. It has been claimed that roll change times have been reduced significantly when …

Traditionally, cold rolling mill rolls present a controlled surface topography that is imprinted onto the sheet during forming and are often coated, particularly using hard chrome deposition.

Reducing Metals. There are many large rolling mills, including rolling mills that roll hot steel slabs 16" thick x 160" wide down to steel plate. When we think of reducing, we think of at least 20% thickness reduction per pass or many passes. In all cases, by reducing hot or cold metals, you improve its grain structure.

roll. In the first stands of the tandem mill the work roll will be chrome plated after grinding to get higher hardness on the surface and get better performance results in the production. The last stand and also all work rolls for the skin pass have to be textured after grinding. These textured rolls give between 40% and 60% of the roughness to the

With the use of alcohol free solutions many printers are finding that our durable ceramic coated rolls are superior to the industry standard chrome plated rolls. The semi-porous microstructure of the plasma sprayed ceramic also makes it more hydrophilic than chrome, and provides a uniform layer of water across the roll.

For long hard chrome plating has been introduced to enable high consistency of the roughness of the strip after skin-pass. This result is obtained owning to the hardness and the high wear resistance that is given by chrome plating.This technique proved to be very efficient to retain consistent roll roughness all along the rolling campaigns.

Substitution of chrome plating for the rolls of skin- pass mill (CRFREEROLLS) final report.

The coating layer is pure chrome so you will increase the hardness to more or less 1000 Hv. Chrome is very fragile and on these kind of rolls a thick layer will break down because of the big forces involved in the mill. 10 to 20 microns will be ok in most cases.
