Sep 02, 1997· The present invention provides a descaling system for hot strip or plate mills. The descaling system includes upper and lower spray headers which are offset from each other along the pass line. Each spray header is adapted to direct a highpressure water spray on the metal product to descale the upper or lower surface thereof.

Preparing steel for painting (descaling) A discussion started in 1998 but continuing through 2017. 1998. Q. I have started a small (Me!) company making steel furniture and other items (park benches, tables, etc.). I usually finish with a primer, then Rustoleum. Most of the items are made from hot roll, and some involve smithing.
The intensely hot Billet is placed on a roller table which carries it into the roughing mill. Descaling. ... Slitting systems. ... type and Garret type coilers are used for obtaining a compact coil of Hot rolled bars rolled upto size of 12 mm .The hot rolled condition of the compact coil makes it suitable for direct cold working with high ...

S MIE AG Hot Flat Rolling Mills 2 SMS Siemag does not treat descaling as an isolated measure but as an integral part of the process chain from continuous casting through hot and cold rolling up to final strip processing. Strips with an excellent surface quality can be produced only if welltuned measures are taken in all process steps.
PDF | In hot rolling, the surface quality of the finished strip depends on the performance of the descaling equipment in the roughing and finishing trains. The design of descaling systems and ...
/ High pressure descaling / Lifting roller table / Chain seesaw; The high pressure descaler has been designed to ensure that future broader and higher slab can be descaled. By the precise setting of the upper scale bar the quality of descaling was again improved.
Mar 28, 2014· Skip to 10:45 for the acid bath I''ve been cutting a lot of parts on the Torchmate plasma lately which need to be either polished or engraved. The scale on the hot rolled .
Dec 11, 2006· the mill scale you are refering to (on hot rolled) is is basically oxide and slag stuck to the surface. it''s there because the steel was rolled to shape at high temperatures. cold rolled is formed at much lower temps (below temps that accelerate oxidiation) and so is pretty clean.
Descaling Steel hydromechanically With KAMAT highpressure pump systems, slabs and billets in rolling mills can be efficiently descaled hydromechanically. With the annealing of steel, oxygen reacts with iron on the hot metal surface. Iron oxides, socalled scale, arise.
Mill Saves US80,000 and Improves Operations with New Descaling Nozzles Problem: A fully integrated Midwestern steel mill manufactures hotrolled, coldrolled and coatedsheet products. Like all steel producers, the mill needs to remove the scale formed on the .
Rolls (cold and hot mill rolls) Profile forming machines; Water descaling unit for rolling mill. In its program, Production and Engineering Company ENCE (ЭНЦЕ ГмбХ) highlights the most significant metallurgical equipment; this equipment complies with the highest international quality standards and may be offered to customers at ...
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 conversion or removal. The aim is thus to provide a uniform homogeneous cooling across the roll .
Hauhinco develops turnkey hydromechanical descaling systems for scalefree results of hotrolled products. Many decades of practical work experience by our employees in descaling as well as in water hydraulic systems in a large number of applications provide the basis for the development of our customized solutions.
The production of hot rolled strip is achieved inline: annealing, cooling, mechanical descaling and pickling are combined in integrated processing lines. Wheelabrator shot blast systems are available for narrow, medium and wide strip and are well proven in this field of application.
ENDLESS ROLLING MILL — ADVANCED SOLUTIONS FROM THE MARKET PIONEERS The concept of endless hot rolling was introduced to meet the increasing demands for hotrolled steel sheet using a costeffective process compared to the conventional batchtype process.
Hot strip mill, hydraulic descaling, highpressure nozzles, impact, spray thickness, descaling efficiency, descaler, energy saving, water savings ... 1,650 mm are being rolled. The mill is designed for a production of 3 Mio t/ year. ... The most important period of the descaling system in .
new technology and process in Hot rolled wire descaling. The process will be demonstrated with MATLAB analysis to evaluate the theory and practice. The object of the project is to obtain a process modi cation for a cleaner, quicker and better environmental control during the process.
OVERVIEW. You''ll find spray technology solutions for every area of your mill in our extensive product line. Our CasterJet ®, DescaleJet ® Pro, VeeJet ® and FullJet ® nozzles are industry standards. But that''s just the beginning – we have nozzles and systems for precision oil application, selective roll cooling and heating, dust suppression, descaling and more.
Descaling System for hot rolling mill TMT box Auxiliary and detached equipment Rolling mill rolls – Cast, HSS Tool steel, PM, Tungsten Carbide, Composite Rolls PARTS OF POWERGENERATING EQUIPMENT,SHIP BUILDING GENERAL ENGINEERING. Wind power generator parts and blanks.
Mechanical Processes for Descaling of Steel Scale is the product of oxidation which takes place during hot rolling. The oxidation and scale formation of steel is an unavoidable phenomenon during the process of hot rolling which involve reheating of steel in a reheating furnace, multipass hot rolling and aircooling in the interpass delay ...
Descaling centers on the explanation of the variations of descaling and descaling systems, understanding descaling forces and the principles of descaling designs. This will allow operators to concentrate their efforts in relation to scale growth control, eliminate rolledin scale, and further enhance the surface quality produced on hot strip ...
