Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a ...
Mar 01, 2018 The descaling water and the cooling water wash the mill scale away from the steel surfaces, flow with the mill scale into the flumes underneath the rolling lines, run at a high speed in the flumes and eventually are discharged into the deep and wide mill scale pits.
For example, if a Steckel mill is utilized, then head and tail scale pits from the Steckel rolling operation are a major yield loss/surface quality issue. In addition, overall scale formation, color, consistency, etc. is the second most common surface quality complaint. Edge defects due …
SOLUTION: Roll cooling water is pumped from a nearby scale pit through a LAKOS Separator to remove the mill scale. The unit purges into a separate section of the scale pit for easy removal and disposal. PROBLEM: Once steel is hot rolled, much of the plate product is subsequently heat-treated to meet required property specifications.

These pits are commanded by an ingot crane, by preference so placed in relation to the blooming mill that the crane also commands the live rollers of the mill. Each pit is covered with a separate lid at the floor level, and after having been well dried and brought to a red heat by the insertion of hot ingots, they are ready for operation.

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 …
Dec 07, 2018 In the hot-rolling process, owing to oxidation reactions, mill scale is formed on the surfaces of semi-steel products in reheat furnaces and on rolling trains and stands [1,2,3].The mill scale is washed away from steel surfaces and flushed into flumes underneath the hot-rolling lines by a large amount of contact water, which includes descaling water and cooling water.

Mill Scale DeOiling. Mill Scale is produced in Hot Rolling operations in the iron and steel industry, in which scale is removed from the surface of hot steel through spray water and contact with the rolls that effect size reduction. The scale thus removed typically discharges with the water used for contact cooling to a scale pit, where the.
