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, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
Cold rolling is a process that occurs after hot rolling in order to reduce the thickness, increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process, but the improved mechanical properties increase the value of the finished product, whether that is a sheet, strip, or coil.
Manufacturing Process > Rolling mill . The process begins with entry of the 180-mm cross section square billets with a weight varying from 2500 to 3250 kg, heated in a water-cooled walking beam furnace with a capacity of 170 t/hour, with bottom and top heating.
Jun 11, 2018. Typical copper tube manufacturing processes are as below: Advantage of Copper Tube Manufacturing Process: 1. Low investment; 2. Easy operation; 3. Products are widely used in the cable, communications, rail transit, new energy, and electric vacuum industries.
First, the production process is different. Cold rolling is processed into a cast-rolled coil (8mm thickness) by a cast-rolling mill and processed by a cold-rolling mill. The hot rolling is made of 400-500mm thick aluminum ingots rolled at high temperatures; Second, the supply of raw materials is different.
19.3.4.1 Process Plant: Hot Rolling Process. This example comes under the category: localized, continuous, manufacturing process (process plants). This case study is based on the automated hot strip rolling mill installed in the plant of JSW Steels, 1 India.

The rolling process is a metal forming process, in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process is mainly focused on the cross-section of the ingot or the metal which is forming.
Rolling mill Rolls and Roll Shop . Rolls are the main and very costly consumables in a rolling mill. They are used to roll steel in the rolling mill and their performance depend on many factors which include the materials used and the loads to which they are subjected to during service.
DS Rolling Mills Private Limited was incorporated in the year 2011, with the sole aim of diversifying into the steel sector of India. Our brand Kedaar Steel is being produced at our flagship production plant, strategically located in the state of Uttarakhand.
's Rolling Mill Rolls Support the World Steel Industry. In 1961, became the first company in the world to adopt the "centrifugal casting" method for the production of mill rolls. It enables to produce a multi -layer composite rolls, which revolutionized mill roll material . Today, we manufacture and market a wide variety and ...
9 17 Rolling Mills Equipment is massive and expensive Rolling mill configurations: – Two-high: two opposing rolls – Three-high: work passes through rolls in both directions – Four-high: backing rolls support smaller work rolls – Cluster mill: multiple backing rolls on smaller rolls – Tandem rolling mill: sequence of two-high mills 18 Various configurations of rolling mills: (a) 2 ...
What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
The invention provides a hot rolling process method for a 2050 alloy cast ingot. The process method comprises the steps of surface milling, heating through a heating furnace and rolling through a hot mill. According to the hot rolling process method for the 2050 alloy cast ingot, the mode of online heating and heat preservation rolling and deformation controlling is adopted, …
rolling at one point in their manufacture. Metal rolling is often the first step in creating raw metal forms. The ingotor continuous castingis hot rolled into a bloom or a slab, these are the basic structures for the creation of a wide range of manufactured Blooms typically have a square cross section of greater than 6x6 inches.
The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …
Wherever you look, seamless steel tubes are an integral part of modern life. Today, the oil and gas industry, the construction and mechanical engineering industries, and automotive manufacturers demand ever better tubes made of higher steel grades, with closer tolerances and new dimensions.
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.
Figure 1 presents the manufacturing processes of rolled aluminum products. Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls.
The manufacturing process can now be completed fully at the medium-size hot rolling mill, enhancing energy efficiency by eliminating the additional step of reheating the pipes in the expander mill. Thanks to lower natural gas and electricity consumption, this investment reduces CO 2 emissions by 7,000 tons per year.
In the rolling mill billets are heated in a computer controlled furnace, having regenerative burners for controlled heating at cheaper cost. The soaked billets are then rolled in bar mill, equipped with alternate horizontal and vertical housing-less stands, …

However, in hot-rolling mills, water used for descaling and cooling steel (process water) and water used for cooling rolls and bearings (cooling water) were reported together. Inasmuch as the steel indus try generally considers all water used in rolling mills as cooling water, it is reported as such in this report.
The main factors affecting rolling pressure are: (1) Absolute rolling reduction. When the roll diameter and the friction coefficient are the same, with the increase of the absolute rolling reduction, the contact area between the rolled piece and the mill roll increases, and the rolling pressure increases.
roll-rolling mills appropriate for high precision rolling as the new rolling mill was selected. 2.2 Outline and features of PFB rolling mill As the new rolling mill, two stands of the three-roll rolling mill were selected (Fig. 1). The major feature of the three-roll rolling mill is its ability to suppress the variations of dimension between the
