Jun 01, 2016· Descaling: Audits of existing hydro-mechanical descaling systems in hot rolling mills as a method to enhance product quality Contribution paper for The Iron & Steel Technology Conference and Exposition 2005, Charlotte N.C., USA 05/2005
The Descaling of hot rolling process as following: Between the Crop Shear and the first Finishing Mill stand sits the #2 Scale Breaker, which is tasked with the final scale removal operation.
The descaling system has a fundamental function inside a hot rolling mill plant: it eliminates the slag or the surface calamine present on the metal by projecting metallic grit.
The mechanical design calculations and features of a modern high-pressure descaler systems at Dofasco No. 2 hot mill to effectively remove the types of scale that grow during hot rolling
The hot rolling process has been divided into many steps of the process, this article mainly talks about the Descaling. The detail of it as following: Between the Crop Shear and th e first Finishing Mill Stand sits the #2 ScaleBreaker, which is tasked with the final scale removal operation. Sprays above and below the transfer bar blast it with 1,500 psi jets of water to break up the scale that
We have created an entire descaling plant for a customer steel mill, an international leader in sheet metal manufacturing.. The descaling system has a fundamental function inside a hot rolling mill plant: it eliminates the slag or the surface calamine present on the metal by projecting metallic grit. In addition to superficially cleaning the sheet metal, the descaling system, equipped with 600

The rolling in of the scale 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

Hot Rolling Mill Other Applications DNX Descaling Nozzles Features Shapes & dimensions Higher impact force and deeper erosion for more efficient scale removal. Lower water consumption with the same impact of existing descaling nozzles. Sharper spray edge definition for optimized descaling perfor-mance. Maximum working pressure 25 MPa n n n 150
High Pressure Descaling with Ancillary Units Customer: Böhler Bleche GmbH. To increase the descaling effect a new high pressure descaling unit was installed. Buma made the whole engineering. This contains: / High pressure descaling / Lifting roller table / Chain seesaw
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

In the metalworking rolling process in hot and cold rolling mills, heat is generated by friction and deformation in the mechanical forming of the rolling stock. As a result, efficient cooling of the rolls as well as the surrounding roll area is essential for the forming process in order to ensure stable roll temperatures and effective heat
Hot Rolling Mill Layout of laboratory 3tandemrolling mill is given in Fig. 1. Themill consists of twoelectric furnaces, anedger, awater jet descaler, a 3tandemrolling mill anda water spray. Themaximumheating temperature of the electric furnace is 1300'C. Agaseousmixture of N2. C02and H20was used to simulate the conditions inside a No. 1Mill No
Regarding hot rolling of steel, the quality of the rolled metal surfaces depends to a large extent on effective descaling. In order to avoid surface damage, iron oxide scale layers are therefore removed from the hot steel surface by high-pressure water spraying prior to the actual hot rolling process.
