also increases roll wear with reduced roll life. Therefore the slabs must have this oxide layer removed before rolling in the mill stand. This scale removal is undertaken in the Primary Descaling Unit which is located immediately downstream from the reheat furnace and before the rolling mill stand. PRIMARY DESCALING TECHNOLOGICAL PACKAGE FOR

The main features incorporated into modern hot rolling mill design include the following aspects: • Large coil weights (> 20 tons) to increase productivity, yield and mill uptime. • Capability to roll strip and plate in widths of > 2000 mm. • Flexibility to operate across the range of soft, medium and hard alloys. •

Electric transmission and control system of hot rolling mill For the technological process of hot rolling production line, the steel billet to be discharged that is heated to the target temperature from the heating furnace will pass high pressure water jet descaling box first to remove scale and then it enters roug

introduction of a hydro descaling method (hydrosuppression) of mill scale on hot finisher, Experimental and theoretical problem research of scale formation on a site of Z finishing train of hot rolling mills for the purpose of decrease in an environmental impact and operative personnell, Rolling. 2 (2016) 3 Å9.

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.

Remarks: Mill scale is formed during the oxidation of the steel surface during reheating, conditioning, hot rolling, and hot forming operations. This substance is usually removed by process waters used for descaling, roll and material cooling, and other purposes. It is subsequently recovered by gravity separation techniques.

The descaling systems in the hot strip mill are equipped with hydraulically adjustable top spray headers due to varying slab and transfer bar thickness. The spray height for the primary descaler is 110 mm and 98 mm for the descaler at the entry of the finishing mill. Strip width dependent descaling is possible. The descaling pressure is 450 bar.
