Since introducing a revolutionary roller guide product in 1945, we have been leading the international steel industry and introducing a number of patented products for rolling mill systems. These original concepts have been continuously developing to meet the market.

Some criterion on this check list are optional while most are crucial to aid you decide well. After the baseline requirements of your two-roll mixing mill are frozen, insist your potential suppliers to give you a quote focused on these criterion. Of course, there are developments in two-roll mill. If your supplier offers additional features ...

5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.

III. Rolling mill: To roll the hot crude steel products into desired shape by passing and squeezing it between set of revolving rolls. The rolls may be plain or grooved rolls depending on product. Rolling operation may contain one or more roll stands depending on reductions required. The Rolling Mill comprises of the following sections: i.

Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the …

Roll cooling is hence an actuator to allow stable rolling conditions of the mill. This is particular true for strip tandem rolling mills with regard to steering the strip, ensuring it remains in the mill centre. In cold rolling applications roll cooling always goes along with lubricating of the roll

Rolling is a type of motion that combines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding.. Rolling where there is no sliding is referred to as pure rolling.By definition, there is no sliding when there is a ...

roller mills used in the feed milling were abandoned flour milling roll stands, used primarily to produce coarse granulations of friable materials. Over time, roller mills have been used to perform a wide variety of tasks related to the production of animal feeds. Roller Mill Equipment Description Roller mills are commonly referred to by the ...

finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".

ROLLING The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control

There are certain types of the rolling process, whereas, in the hot rolling process, the metal is heated at its desirable temperature, when the metal is properly heated then the metal should be passed between the one or more rolling mills to gain the proper desirable shape. This process is vastly used in respect of any other rolling process.

1.7 Rolling mill control: Production of continuous sheets and strips is one of the attractive features of modern rolling mills. However, control of sheet thickness and cross-section is a real challenge. In order to continuously monitor the thickness of sheets rolled, x-ray or gamma ray sensors are used.
