The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are descaled 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 is maintained by optical laser gauges and manual micrometer checks.
In the 19th century roller mills were adapted to grist mills before replacing them. The mill used either steel or porcelain rollers. Between the years 1865 and 1872, the Hungarian milling industry upgraded and expanded the use of stone mills combined with roller mills in a process known as Hungarian high milling.
Chemical SEPT mill rolls are extremely good at limiting the consumption of chemical and oil. While maintaining the integrity of process fluids, the Chemical SEPT Mill Rolls also reduce the consumption of water, chemical solution and oil by a far better wringing. .

Finishing mills roll cold coils of pickled hotrolled sheet to make the steel thinner, smoother, and stronger by applying pressure, rather than heat. How? Stands of rolls in a coldreduction mill are set very close together and press a sheet of steel from onequarter inch thick into less than an eighth of an inch, while more than doubling its ...
Jul 18, 2013· AbstractRoll wear in a hot strip mill (HSM) is a detrimental process, which progressively worsens the rolls. This necessitates replacement of the rolls after rolling a number of strips. Roll wear adversely affects the strip shape and the performance of a mill. It is important, therefore, to quantify roll wear during the rolling process. The present paper proposes a wear model for prediction of ...

As an integral part of a modern roll maintenance program, roll grinding and balancing uses machinery with accurate inspection and measurement equipment. This paper provides practical tips on roll inspections, balancing, grinding and grooving. In addition, we discuss proper roll handling during removal, storage, transport, and reinstallation.
The effects of hot rolling on the surface roughness and oxide layers such as reduction, roll speed, and entry temperature, were investigated to identify any significant parameters. Hot rolling experiments were carried out on a HILLE100 experimental rolling mill. Five .
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished 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.

Steel Designations and Chemistry If the purchaser of Cold Rolled Full Hard Sheet plans to further process the product such as by annealing to soften the product or apply a hotdip coating, it is important to order the proper steel chemistry. The steel chemistry can be specified to allow the customer to meet the enddesired mechanical properties.
In hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls.
Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.
