Aligning Rolls COOLING BED ALIGNING ROLLS A LongProducts Cooling Bed is an essential piece of equipment in every steel mill that produces a variety of different products in a varying lengths. A typical product range would be rebar, rounds, squares, angles, channels flats. Our Aligning Rolls are being used in many steel mills throughout
Coolants are used to wash away oils, oxides, slivers, and dirt generated during the forming, welding, and sizing of tubes and rollformed profiles. These coolants are a mixture of water and refined chemicals that help cleanse the process, protect part finish, extend tool life, and inhibit rust and corrosion on the profile and machine.
Long product is a common name for (i) reinforcement steel bars, (ii) shaped steel bar products such as rounds, flats, squares, and hexagon etc., (iii) sectional products such as angles (equal and unequal), channels, beams, tees, and special profiles etc., and (iv) wire rods. Mills which roll long products are known as long product mills.
Hydraulic gap control (HGC) and work roll bending pressure regulation were performed by discrete hardware with target reference generation by the mill drive controllers. Pulse modulation of multizone roll cooling sprays was performed by the mill drive controllers. System sequencing was implemented as ladder logic in the mill drive controllers.

Depending on the properties of the process material and its desired temperature, the rolls may be internally cooled or heated by using circulating cooling water or a suitable heating medium. The basic mixing operation is illustrated in Fig. The material is charged between the rolls in the form of lumps, pellets, chunks, or powder.
In a sudden mill stoppage with big cobble, it is necessary to stop the roll cooling immediately and allow the roll to cool in a normal way without quenching to avoid deep fire cracks. Also, in a sudden mill stoppage with big cobble, it is advisable to inspect the roll surface for deep cracks before restarting the mill.

After the finishing, mill the bar is passed through the notwist mill (NTM) having alternate arrangements of vertical and horizontal tungsten carbide roll stands followed by water boxes for controlled cooling for achieving the properties. The bars are then transferred to a cooling bed, after which they are positioned, trimmed, bundled and packaged.
The steel industry plays a pivotal role in developing and growing any nation's infrastructure. In this context, the steel rolling mill is a critical component that transforms raw steel into various shapes and sizes for construction, automotive, and other industries. To ensure the efficiency, quality, and longevity of the rolling process, one of the crucial aspects to consider is roll cooling.
The finishing mills roll the rolling stock in tandem, meaning each bar is rolled through all finishing stands at once. Laminar cooling of the hot rolled strip: After exiting the finishing mills, the strip is carried down by a large number of individually driven rolls through banks of lowpressure, highvolume water sprays that cool the redhot ...

Given that the 4high CVC mill has work roll shifting function, it can use the KWRS technology to realize similar function of the 6high UCMW mill . However, the edge drop control capacity of the 6high UCM rolling mill is obviously insufficient because of the lack of work roll shifting function.
The roll surface emerges from the bite at high temperature and is quickly cooled by conduction into the cooler inner parts of the roll. When the surface meets a spray there is a sudden depression in temperature and then a recovery after the spray. Below the surface the temperature distributions are very different and much less varied.
