Step 1: Aluminum Stock Preparation. Aluminum slabs for use in the rolling process. The process starts when the rolling mill gets aluminum slabs or billets ready for rolling. Depending on the desired materials properties for a particular roll, they must first decide whether to heat the stock or not. If they do not heat the aluminum before ...
Rolling mill consists of rolls, bearings to support the rolls, gear box, motor, speed control devices, hydraulic systems etc. The basic type of rolling mill is two high rolling mills. In this mill, two opposing rolls are used. The direction of rotation of work can be fed into the rolls from either direction. Such mills increase the productivity.
The steelmaker had been exploring the use of digital technologies to optimize its rolling wire production and will now benefit from the expertise and metals industry domain knowledge of ABB. As part of the contract, ABB will provide its medium voltage drives for high power applications, MEGADRIVE-LCI, together with AC 800PEC controllers.
While the rolling process today consumes a minimum amount of natural gas, 30-40 years ago the use of the fuel was more prominent. Indeed, before the introduction of the continuous casting process, liquid steel was poured into ingots, which had to be rolled into semi-finished products on blooming mills and only after that sent to plate and ...

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.

Energy consumption in small and medium sized re-rolling mills takes place in two forms namely (i) electrical energy, and (ii) fuel or heat energy. Electrical energy is used directly in main rolling process for shaping of hot billets into rolled product (rolling mill, and shears etc.), in reheating furnace (coal pulverizer, blower, and pusher ...
Answer: The process of cold rolling a metal alloy starts with either sheet metal or strip coil. These materials are placed into large rollers, which compress it down and squeeze it under high pressure just below its ultimate tensile strength. In simple terms, cold rolling is an industrial proces...
The company Loesche in Düsseldorf is pleased to receive a follow-up contract for a coal mill, of the type LM 28.3 D, which is the same type of coal mill already successfully deployed by RWE Power AG in Niederaußem.

Coal Mining and Production Industry Description and Practices Coal is one of the world's most plentiful energy resources, and its use is likely to quadruple by the year 2020. Coal occurs in a wide range of forms and qualities. There are two broad categories: (a) hard coal, which includes coking coal (used to produce steel) and other
4.1 Types and Classification of Different Furnaces Based on the method of generating heat, furnaces are broadly classified into two types namely combustion type (using fuels) and electric type. In case of combustion type furnace, depending upon the kind of combustion, it can be broadly classified as oil fired, coal fired or gas fired.
