The temperature of the hot melt is reduced by means of a chilled roll. The melt is cooled down very quickly, with possible flow rates of up to 100 kg/h. After cooling, the product is reduced to flakes by means of a kibbler. The subsequent milling procedure can be done on line by directly adding a hammer mill or a conical mill.
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 ...
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.
hot roll mill descaling system Construction Waste Crusher Construction waste refers to the construction, construction units or individuals to construct, lay or demolish all kinds of buildings, structures and pipe networks, etc., and generate the spoil, spoil, waste, residual mud and other wastes generated during the repairing process.
descaling system. During slab reheating the slab surfaces develop an oxide layer inside the furnace (scale) which, if not removed, will be rolled into the plate surface leading to surface defects and reduced product quality. The rolling in of the scale also increases roll wear with reduced roll life. Therefore
Manufacturers across the steel, aluminum and metal fabricating industries depend on spray technology from Spraying Systems Co. for their daily operations. Our spray nozzles, headers, lances and turnkey systems will optimize your operations while conserving water and reducing maintenance.
Dec 03, 2015· Descaling of heated slab is a must in the hot strip mill for attaining good surface quality of the hot rolled strip. Descaler operation need to be optimize in order to ensure maximum scale removal and hence enhanced cleaning at minimum cooling of the heated slab.
A method and apparatus for removing oxide scale from the surface of hotrolled stainless steel strip comprises uncoiling the steel strip coil, removing the coil bias and cracking the surface scale in a first scalebreaking apparatus, flattening the strip by removing edge wave and center buckle to a flatness approaching table top flat, the tolerable deviation therefrom depending upon the gauge ...
Jan 21, 2019· Identifying Mill Scale. Mill scale (often known simply as ''scale'') refers to the thin, flaky texture that forms on the outer surface of hotrolled iron oxides and metals. It is a byproduct of manufacturing hotrolled metal plates and sheets, occurring as the surface oxidizes during the heating, conditioning and hot rolling processes.
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.
hot mill roll lubrication systems Pochiraju Industries Ltd. Effect of processing parameters on scale formation during hot steel The principal phase of the scale formed in hot rolled steel strips is tertiary scale forms on the steel surface after descaling or between each mill stand in roll gap lubrication system on the formation of the tertiary scale during hot strip rolling
Sep 08, 2017· Several types of descaling processes are used for removal of scale from the surface of the hot rolled steels. These descaling processes are usually classified into four categories. These are (i) flame cleaning process, (ii) mechanical descaling processes, (iii) hydraulic descaling process, and (iv) chemical descaling processes.
Nov 28, 2017· 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.

SMS DEMAG Hot Strip Mills 10 The drumtype shear installed between the roughing and finishing mills of a hot strip mill crops the transfer bar at its head and tail. In special applications, the drumtype shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drumtype shears built so far,
Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys. A solution called pickle liquor, which usually contains acid, is used to remove the surface is commonly used to descale or clean steel in various steelmaking processes.
