Advanced Control for Hot Rolling Mills M. J. Grimble and G. Hearns Industrial Control Centre, University of Strathclyde, Glasgow, UK Summary. Hot strip rolling mills are characterised by a process which has many interactions, is distributed with dominant transport delays and has a lack of measurements due to the severe environment.
As plants are being modernized and automated for greater efficiency, hot testing is becoming an integral part of the production process. Its advantages at this stage are two …
Here, a white-hot piece of iron is approached by two men to the first roller of the rolling mill. The piece of iron rests on the drawbar, which they lift with combined force. ... The later added subtitle "Modern Cyclops" - as an allusion to the blacksmiths of the fire god Hephaistos - speaks rather for the impression of a dully working mass ...
Starting materials such as blooms or slabs at an elevated temperature flow from the continuous casting process directly into the rolling mills. In smaller operations the materials start at room temperature and must be heated either in a soaking pit, or by induction heating before being fed into the mill. Hot rolling improves: Toughness and …
The state-of-the-art of both technology and operation practice of a hot al rolling mill are discussed. The focus is first on the control of entry temperature in the finish mill.
Firstly, the new trend of hot strip mill line is described. Then, the recent progress of mathematical model, sensor, actuator, control theory application and rolling schedule of hot strip mill is discussed. Finally, a summary of plate rolling process control is given. 2. Technology trend in hot rolling process
Cold rolling process is a technique which is mostly applied for the production of smaller sized products with high strength, these products are achieved by including cluster mills as shown in Fig. 3, it does not reduce the thickness as much as hot rolling [11].The considerations are met, when the metal pieces are "worked" at temperature …

Taking the hot rolling production process as an example, it consists of a reheating furnace, a roughing mill, a finishing rolling mill and a cooling and coiler sub-process. The final quality of hot-rolled coil products consists of three types: size (e.g. steel strip thickness and width), shape (e.g. crown, wedge and flatness) and surface (e.g ...
FENN rolling mills can be custom designed and built to help metal manufacturers perform test runs to refine their processes for maximum productivity and efficiency. FENN Rolling Mills are available in a wide range of configurations and sizes, for an assortment of engineering, manufacturing, and research and development (R&D) …
Fig. 1 shows the configuration of a 7-stand hot strip mill set up at Algoma Steel. The rolling mill is equipped with a slab reheat furnace, followed by an edger for width control before a single roughing mill stand. The pre-deformed strip is then de-scaled and is transported into 6 stands of 4-high rolling mill for stepwise thickness reduction ...
Accu-Roll 2-roll tube rolling mill is used in rolling process of the complete set of Accu-Roll equipment for hot rolling seamless steel tube production line. At present, TYHI has successfully designed, manufactured Φ168mm, Φ219mm, Φ273mm series Accu-Roll hot rolling production line.
Started as a family run business, PP Rolling Mills Mfg. Co. is a today a professionally managed company. Set up by late, Mr. Prem Khanna, the youngest son of the Late Shri Dharam Chand Khanna, PP Rolling Mills Mfg. Co. Pvt. Ltd. is a tribute to the vision and enterprise of his father who set up a small factory to manufacture hand presses after the …
The benefits of intermediate induction heating can also be seen in the rear area of compact hot rolling mills. In the endless rolling process for very thin strip grades or silicon steels, compact integrated induction units compensate for the temperature drop between finishing stands and maintain the right temperature level up to the end of the ...
The hot strip mill is named according to the work roll length. The roll mill with a length of more than 914 mm is called the wide strip rolling mill. The finishing mill with a length of 1700 mm is called the 1700 mm …
Our hot rolling mills are designed to operate at a high level. They combine sophisticated automation, sturdy construction, and careful control systems to guarantee that the finished products are consistently of high quality and precise dimensions. Whether it's for producing critical components in the automotive sector, structural elements in ...
Casting rolling mills are typically 2 or 4 high hot mills capable of providing consistent thickness strip from hot cast incoming material. Embossing Rolling Mill. Specialized rolling mills that emboss a pattern or indent into metal strip are known as embossing mills. These patterns can be used for decoration, to help with structural qualities ...
Hot Rolling Mill Components. Hot rolling mills typically consist of a series of rolling stands, which are made up of two or more rollers that rotate in opposite directions. The rollers apply pressure to the steel as it passes through the mill, which causes it to deform and reduce in thickness and length.
Our hot rolling mills are capable of producing flat steel from thin gauges of 1.2 mm to high-strength steels up to 25.4 mm thick, including stainless steel. Apart from the outstanding technological quality of our plants, which we continuously develop, we are also committed to our long-term technology partnership, so that your production always ...
The book begins with a brief history of metal rolling and an overview of the tandem hot metal rolling process. It then discusses process models, including physical …
Two-, three-, and four-high rolling mills. Determined by the mill stand quantity, these mills roll in opposite directions to press and finish the metal. In addition to the different types of rolling mills, your metal manufacturer might use a cold rolling mill or a hot rolling mill to work certain types of metals and create different products.
In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.
This study is a comprehensive review about steel hot rolling mill scheduling from an operations research point of view, but some seemingly obvious articles are not included in the study for the following reasons: (1) the articles are not about steel hot rolling mill but are about aluminum or other metals (de Ladurantaye, Gendreau, & …
