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 ...
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 well-tuned measures are taken in all process steps.
This process, called descaling, is used in hot rolling, for example. A number of jets must be used to cover the total width of a rolled strip. High quality and homogeneity of the descaling process ...
SMS DEMAG Hot Strip Mills 8 The coilbox arranged between the roughing stand and the finishing mill of a hot rolling mill forms coils of transfer bars, thus serving as both material and heat accumulator. During uncoiling, the former trans-fer bar tail runs into the finishing mill as transfer bar head. The coilbox is employed in new facilities ...

A hot-rolled steel strip having a hot-rolled scale adhered to its surface by a leveler or a skin pass roll at 5 kgf / A method for descaling a hot-rolled steel strip, which comprises applying a tension of not less than 2 mm, rolling under high pressure with a cold rolling mill.
AUDITS OF EXISTING HYDRO MECHANICAL DESCALING SYSTEMS IN HOT ROLLING MILLS AS A METHOD TO ENHANCE PRODUCT QUALITY Jürgen W. Frick Lechler D-72555 Metzingen / Germany E-mail : [email protected] Abstract : Over the life span of a rolling mill the requirements in terms of product quality and the range of steel grades may change significantly.
Sep 01, 2016· Carbide Mill Rolls for Hot Rolling Mill will improve product quality, reduce downtime and increase productivity to bring better production economy.Tungsten Carbide Mills Rolls are mainly used in wire rod rolling mill, steel rebar rolling mill.. Grades of Carbide Mill Rolls:
Jan 14, 2017· Hot Rolling is employed for rolling of steel slabs to hot strips in hot strip mills. Like any other hot rolling operations, rolling of hot strip is also a plastic deformation of the material of the slab caused by compressive force applied through a set of rolls. The cross section of the slab is reduced by the hot rolling .

Keywords: HSM (Hot Strip Mill), Descaling, Rolled in scale, Impact force, Erosion pattern 1. INTRODUCTION Descaling is a key process of hot rolling, especially when a good surface quality of the hot rolled products is demanded. Many studies have been made on the descaling technique of the hot strip mill (HSM) process (1-3). The key descaling ...
The present invention relates to the descaling of rolled material (for example, steel) which may be produced by e.g. a hot strip rolling mill. The present invention relates to both the method and apparatus aspects of descaling. 2. Summary of the Prior Art. It is well known to use a hot strip rolling mill .
of hot strip mill, tunnel furnaces are the central link be-tween the caster and the rolling mill. They are used to heat and/or equalize the slab temperature in reheating operations of about 12–20min. In general, tunnel furnaces operate over the temperature range of 1000–1200°C. During hot rolling .
Application: Descaling for a Hot Mill Pump Details: Ingersoll Rand 6x11 DAH ... A mill's descaling pump was cycling from full to low flow several times per hour depending on the mill rolling rate. .
