Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.

May 25, 2017· The amount of mill scale generated in a rolling mill depends on the type of the reheating furnace and on the practice of rolling adopted in the mill. It is generally in the range of 1 % to 3 % of the weight of the steel rolled. Mill scale mill scale is a layered and brittle material, composed of iron oxides with wustite as a predominant phase.

This novel method of producing clean mill scale by dynamic separation of the mill scale from the fastmoving fume wastewater in the hot rolling process could be a costeffective and environmentfriendly solution for sustainable recycling of the mill scale in the ironmaking and steelmaking process.
Oxide copper ore, lowgrade copper sulfide overburden, and other coppercontaining materials are stacked into a heap. Leach solution (pH approximately 2) is sprinkled or flooded on top of the heap and percolates through. The leach solution containing the dissolved metal eventually flows out of the heap into a collection pond.
The effects of hot rolling on the surface roughness and oxide layers such as reduction, roll speed, and entry temperature, were investigated to identify any significant parameters. Hot rolling experiments were carried out on a HILLE100 experimental rolling mill. Five lubricating modes were used in the rolling tests to examine the deformation ...
