Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing ...
The rolling process is shown in Fig. : Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
Two multivariable models for the hot rolling mill at the Danish Steel Works Ltd. have been derived and identified. The purposes of the models are to: 1) describe the process dynamics; and 2 ...

Sep 11, 2014· Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel''s recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.
Oct 20, 2017· This video discuss draft, bite angle, length of contact,condition for maximum draft, slip and power requirements for rolling operations ... Hot Rolling Mill Duration: 6:31. ... Hot Rolling ...
The vibration demolding of the crystallizer leads to slab thickness deviation in continuous casting processes. Therefore, in this paper, the dynamic model of the hot strip rolling mill vibration resulting from entry thickness deviation is proposed and its dynamic characteristics are studied. First, the dynamic model of vertical vibration in the hot strip rolling mill is established based on ...

The rolling of steel is mainly hot rolling, and the cold rolling is only used for producing small steel and thin steel. If interested in our hot rolling mill machine (wire rod rolling mill and TMT rebar rolling mill) or cold strip rolling mill, please contact us.
Hot rolling mill thus helps in reducing the size of a metal thereby molding it into the desired form and shape. Rolling mills perform the function to reform the metal pieces such as billet and ingot whilst maintaining its well equipped micro structure into bar, wire, sheet, strip, and plate. Hot rolled products are frequently categorized
Jul 01, 2007· This paper considers some of the control issues in hot rolling mills. Hence to set the context, first we give a brief description of a typical process. The role of a hot strip mill process is to roll the slabs produced in a continuous casting process and produce strips of thickness –20 mm. Fig. 1 shows a typical layout of a hot strip mill.
9 17 Rolling Mills Equipment is massive and expensive Rolling mill configurations: – Twohigh: two opposing rolls – Threehigh: work passes through rolls in both directions – Fourhigh: backing rolls support smaller work rolls – Cluster mill: multiple backing rolls on smaller rolls – Tandem rolling mill: sequence of twohigh mills 18 Various configurations of rolling mills: (a) 2 ...
Jun 18, 2014· Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.

Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.
rolling mills (8 stand roughing rolling mill, 4 stand intermediate rolling mill, and 4 stand finishing rolling mill) was built by MorganSumitomo Heavy Machinery Co. Ltd.. In the 1980s, the aimed quality of products was shifted toward highvalueadded special steel quality, and, to achieve this, in 1986, a threeroll finishing rolling
Apr 01, 2012· Severe vibrations, known as chatter, occur often in both hot and cold rolling of steel. A recent chatter outbreak at the second stand of hot strip mill in Hastings, Australia, prompted an investigation into the causes of chatter by a literature review, the development and deployment of mathematical models, and a rigorous analysis of plant observations.
and mass flow in hot rolling mills can be satisfied by proper control of the strip tension and looper angle Figure 1 shows the tension and looper control in a typical finishing mill Traditionally looper angle control has been performed by changing the rotating speed of a main motor but there has been no tension feedback. Details
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.
