Generally, the annual capacity of section steel rolling production line is from 50,000 tons to 1,000,000 tons. The raw materials for section steel rolling production line are continuous casting square billets, rectangle billets, or beam blanks. Process flow diagram of section steel rolling:
The rolling process is shown in Fig. 2.1: 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.
The malleability of aluminium means it can be easily rolled into thin sheets. To that end, aluminium alloys are cast into rectangular beams up to 9 metres in length, these are then rolled into sheets from which aluminium foil and beverage cans are made, as well as parts of automobile bodies and a vast array of other products.
process. Secondly, most of the hot rolling models are more of continuous flow process in a sense that hot slabs undergo all the successive stages of rolling in one go/pass successively at consecutive rolling mills. However, Tang et al. (2001, p.12, section 5.1) describe that in the
The function of the aluminum rolling mill is to roll the original aluminum into a Cast-rolled alloy strip suitable for cold rolling. The molten aluminum must be supplied continuously. The melt of aluminum alloy must be clean and have the same chemical composition, …

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…
The flow of metal during rolling is continuous and almost entirely in longitudinal direction. Most primary rolling is done in either a two high reversing mill or a three-high continuous rolling mill. Final products from hot rolling …
The steel industry is one of the biggest and most important industries worldwide. It has always been a major driving force of the economy. Its products are indispensable, for example, in metal processing, automotive manufacturing, mechanical engineering and in the construction industry.
Costs of aluminium rolled products mainly driven by global prices The costs of producing the majority of aluminium rolled products remain largely driven by raw materials costs, i.e. metallic input costs; they typically account for over 70% of a rolling mill's full operation costs. Overall, raw materials costs are largely driven by the LME price.

roughing mill, the cooling model predicts subsequent rolling temperatures and controls the speed of the fin-ishing mill with an optimized speed diagram. Since the future rolling speed is thus a known factor, it can improve the accuracy of the values for the final rolling …
May 01, 2017· Rolling is used for making hollow seamless tubes, rods etc. Large length cross sections are produced by rolling process. It is use for mass production of threaded parts like screw, bolts etc. Gears can be cut on gear blank by rolling process. Construction material, roofing panels, partition beams, railroads, etc. are rolling product.
Rolling mills are not a standard machine tool, nor are they built for stock. They are designed and built-to-order to specifically accomplish an end product or process. At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills and blooming mills.
As regards "abnormal" rolling conditions - which are more or less very "normal" for rolling mills - roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll
2 Sensor systems for process optimisation in rolling mills and strip finishing lines References (extract) For more than 40 years, Micro-Epsilon has been a reliable industrial part- ner in precision measurement technology for inspection, monitoring and
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 …
We offer Aluminum Cold Rolling Mill that is used for feeding hot rolled aluminum strip after being cooled to room temperature, there it is steadily passed numerous times between series of rollers until it reaches desired measurement and formed into a coil.
There is almost no end to the uses of high-grade steel strip in today's world. They include everything from aircraft to beverage cans. That explains why we design our cold rolling mills to be just as versatile. What's important to you are not only high flexibility and product quality, but also sustained, cost-effective operation of your plants.
Nov 27, 2015· Understanding Rolling Process in Long Product Rolling Mill Steel rolling consists of passing the material, usually termed as rolling stock, between two rolls driven at the same peripheral speed in opposite directions (i.e. one clockwise and the second anti-clockwise) and so spaced that the distance between them is somewhat less than the ...
