A deflector roll for measuring and checking the flatness of sheet metal under tension and as it passes round the roll comprises a non rotatable inner portion carrying axially spaced radial stress detectors in axially spaced measurement zones spaced by neutral zones, and a continuous rotatable outer envelope to be contacted by the sheet and to …
Steckel mill rolling. On the last pass the strip passes under the delivery-side hot coil furnace to the laminar coolers and down-coiler. Notwithstanding the immense benefits derived from Steckel mill rolling, the development of cold ends during the later roll passes can lead to microstructure, and hence

STECKEL MILLS 4 Steckel mills The classic Steckel mill configuration consists of a rougher with an attached edger that jointly roll out slabs to transfer bar thicknesses of 25 – 45 mm. Next, a four-high revers - ing stand rolls the transfer bar to the desired finished strip thickness in 5 – 9 passes. To keep the material hot during
The process layout of these mills allows production of around 1.5 to 2 million tons per year, an example is the mill for Xiangtan Iron & Steel (China). Many layouts already have the provision for future extension of production and prodct mix. The concept of Plate/Steckel mills provides a middle ground in plate rolling by producing discreet ...
Functional enhancements to improve the rolling process within plate and steckel mills By M. Kurz, B. Schmidt, D. Krautwurst, Primetals Technologies Germany GmbH,M.

Analysing metal working processes. G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction …
The Steckel Mill PLC will do the sequence control of the process in Steckel Mill. During the pass in Steckel Mill, actual values like roll force and strip temperature are measured by Steckel Mill PLC and sent to Model server. After 35-50% of that pass length is rolled the model server will process the measured
Coiler drums are used to coil the rolled steel sheets in Steckel mills maintained in a temperature range between 900°C and 1,100°C. We have developed and commercialized materials with high strength at high temperatures, high build-up resistance, and high thermal shock resistance, and we supply them to many users both in Japan and overseas.
Beside a vast number of successfully realized mill modernizations and upgrades, since 2005 we supplied 27 new plate lines (22 Plate Mills, 5 Steckel Plate Mills). Also we implemented already 7 heat treatment lines featuring …
Steckel mill – A four-high reversing rolling mill, a Steckel mill allows the rolling of a large slab by providing heated coil furnaces or boxes on both sides of the mill to store the increased length produced during rolling Steel – Alloy of iron and carbon with a carbon content of less than 1.7% Steel bath – The hot, molten steel in a ...
The coupled pickling line and tandem cold mill (PL-TCM) using Universal Crown Control Mill (UC-MILL) has become a de facto standard for large-scale prodcution of high-quality strip. Main benefits: Highest production rates (1.2-2 million t/a) with optimized yield. Tight tolerances for strip thickness and flatness with uniform high-quality surface.

increase the specific weight of coils rolled on Steckel mills. The realization of cut-to-length lines that could handle wider, thicker, and heavier coils further enhanced the demand and use of such mills. This lead to new layouts allowing the use of Steckel mills to roll longer runouts, either by extending the length of roller tables (as was the
