The Mobile Jaw Crushing Plant is not limited to the location of crushing operation, and it reduces the cost of material transportation.View More
While most other crushers reduce rocks by pushing them by force against metal, VSI crushers also use the rock fed into the machine to crush itself.View More
HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a key element of steel production. Since close to half of all steel produced is hot-rolled to strip, mills require maximum
Hot Strip Mill. HSMM is one of several commercially licensed technologies developed under AISIs advanced process control programme, a collaborative effort among steelmakers and the U.S. Department of Energy to create breakout steel technologies.
The complex control systems have been applied to hot rolling processes and, now, the control area covers the whole line. The process technology of hot strip mill has matured; however, the development of advanced control in this area is still active, for the reason that the demand to improve quality has become increasingly severe.Cited by: 24
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, The last four roughing mills each incorporate edgers for width control and roll the bar from five to six inches thick incrementally down to around an inch and a quarter, depending on the customer’s ordered width, gauge, and steel grade. As
Hot strip mills in these days are either conventional hot strip mills or strip mills for rolling thin slabs. The primary function of the conventional hot strip mill (HSM) is to reheat the semi-finished steel slabs (rolled or continuously cast) to the rolling temperatures and then to roll them thinner and longer through a series of rolling mill stands driven by large motors and finally coiling
31.03.2015· ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hot-strip rolling mill in Duisburg. The animation shows how it all works.作者: thyssenkrupp
SMS DEMAG Hot Strip Mills 10 The drum-type shear installed between the roughing and finishing mills of a hot strip mill crops the trans-fer bar at its head and tail. In special applications, the drum-type shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drum-type shears built so far,文件大小: 857KB
You'll appreciate X-Roll ® hot strip mills from SMS group as all-round plants for high-quality hot strip. They are designed to produce flat steel from thin strip with a minimum final gauge of 1.2 millimeters to high-strength pipe steels up to 25.4 millimeters thick, including stainless steel grades.
The Steckel Mill occupies a special niche in hot flat rolling, operating at a lower economic volume than tandem hot strip mills but capable of greater widths and especially suitable for particular alloys, including stainless steels Its metallurgical and process control complexity is comparable to the Plate Mill, and its design, operation and yield characteristics are highly specialized .
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 process. The material gets squeezed between a pair of rolls, as a result
Process control in the hot strip mill impedance spectroscopy for remote analysis of steel microstructures. By C. L. Davis, S. J. Dickinson and A. J. Peyton. Abstract. The current state of impedance spectroscopy as an online technique in hot strip mills to determine the progress of phase transformations in steels is reviewed. Electromagnetic sensors have the advantage of being non
The integration skills of Primetals Technologies and our broad base of engineering disciplines, from machine design through process control and metrology, make us an ideal partner in the maintenance and development of the steckel mill as a lasting asset. The potential of the modular approach is wide-ranging too. It can equip a new operator for a low-volume market at entry with scope for future
It has long been recognized that some, if not most, of the variations in thickness of strip produced by a cold-reduction mill have their origin in the hot rolling process. For example, it has been shown that in many coils of metal produced by a cold mill several heavy areas can be identified which result from water-cooled skids in the slab-heating furnace preceding the hot-strip mill. Another
FLAT PRODUCTS Hot Strip Mills Modern rolling mills that ensure product quality and mill productivity. 25/115 . The Hot Strip Mill represents the most productive solution for flat rolled products. It provides the highest level of productivity together with a large product mix and outstanding quality. Yearly productivity of Hot Strip Mills can vary from 2 to 6 Mtpy, depending on the
Hot strip mill. Around a third of the products we send out to our customers, are hot rolled. In the hot strip mill (Ghent), slabs coming from the continuous caster are rolled out to steel plates with a thickness of around 1.25 to 13mm
MODELLING AND CONTROL OF A HOT ROLLING MILL F In this work, a thickness output control for a strip roll-ing mill process is proposed. The proposed scheme has the knowledge that permits the application of optimal control techniques. It was developed a versatile environment for simula-tions that was used in the analysis the behaviour of a rolling stand. The results was used for validation

The performance of hot strip mill depends on the cooling process after hot rolling. One important point of improving the technology of controlled cooling after rolling is understanding the effect of process parameters. Heat transfer coefficient is a significant physical parameter during the cooling process. However, there are a lot of difficulties to solve it directly.
