descaling system. The paper focuses on the recent innovations of descaling nozzles. INTRODUCTION Besides the customers in the automotive industry, manufacturers of construction and agricultural machinery using hot rolled steel for outer body parts
28/11/2017· Descaling hot rolled steel is very important, because the heat scale does not provide a very good adhesive surface for the coating. You are only missing one thing. A short term corrosion inhibitor for the rinse water.

Mill scale (often known simply as 'scale') refers to the thin, flaky texture that forms on the outer surface of hot-rolled iron oxides and metals. It is a by-product of manufacturing hot-rolled metal plates and sheets, occurring as the surface oxidizes during the heating, conditioning and hot rolling processes.
Descaling is a process of removing oxide deposits from a heated stock, either before or during forging operations. Physical methods for descaling include use of wire brushes, extra blows, scraping devices, polishing or blasting.

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.
High Pressure Descaling before the Finishing Mill For wear reduction and better water drain inside the descaler box we received the order to modernize the descaling unit on the entry side of the finishing mill. We reused the existing rotating descaling system.
In this way, when the hot rolled steel strip 1 to which tension is imparted is sent to the rolling mill 5, crack is liable to generate in a scale layer at the time of biting with work rolls, adsorptivity of rolling oil is improved and the coefficient of friction is lowered.

Rolled steel products are used in many manufacturing fields. For corrosion protection and preservation, and for subsequent coating, their surfaces must be clean and free from rust or scale. Steel sheet, plate and section descaling machines, otherwise known as Roller Conveyor Blast Machines, are designed for the mechanical descaling and/or preservation of steel surfaces in one pass.

and finally coiling up the lengthened steel sheet for transport to the next process. The Hot Mill rolls slabs weighing up to 30 tons between 30" and 74". Steel slab 8 to 9 inches thick and up to 36. feet long is rolled into strip as thin as 1/16 inches and up to a half-mile in length. Coils are produced with a 30".

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.
