This defect looks like a pitted surface. Often called scale pits or pock marks, this defect is caused by worn hot mill rolls, or high hot mill coiling temperatures. Pits can also appear on hot rolled coils (picture 2).

 — Defect Characteristics; Scar is an irregularly shaped, raised metal sheet attached to the surface of the steel strip, showing leaf-like, feather-like, bar-like, fish-scale-like, tongue-end-like, etc. . There are two types of scars: one is connected to the body of the steel and folds onto the surface of the plate, not easy to fall off; the other is not …

 — 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.

 — In a rolling mill where the steel will be stretched and squished the mill scale will first be removed mostly by water jets, or by sand blasting in some shops or by vibrating rolls in others and the mill scale will fall into a pit below the equipment where it will also be joined by rolling mill lubricants and bearing oils and water. From there ...

We put that into the mill scale pit and in three to four hours had cleaned out ...

 — Continuous Hot Rolling. A continuous hot-rolling mill may have a conveyor that is several thousand feet long. The steel slab exits from a slab reheating furnace onto the beginning of the conveyor. Surface scale is removed from the heated slab, which then becomes thinner and longer as it is squeezed by horizontal rolls at each mill, usually ...

Kenmochi et al. [2 ] used a laboratory-scale rolling mill and an actual rolling mill to examine the eects of micro-defects on the surface gloss of cold-rolled stainless steel strips. They discussed the mechanism of micro-pits in cold rolling. Surface gloss is strongly aected by micro-defects on the surface. R.

the invention comprises a method of preventing deposition of oil on steel mill scale particles comprising adding from about 1 part per million to about 500 parts per million of an amine acrylate/acrylic acid copolymer to mill flume water. Once the copolymer is added, deposition of oil onto the scale is prevented. Oil and water are subsequently separated in the scale …

ZSP Solution Conventional Scale Pit System; Water coming from the rolling mill direct cooling line are separated into different fluxes: those containing large/heavy scale are sent to the scraper conveyor packages, while those containing small/light scale are collected in a separate pit and directly pumped into the longitudinal clarifier.
