Mar 15, 2016· In steel plants reheating furnaces are used in hot rolling mills to heat the steel stock (Billets, blooms or slabs) to temperatures of around 1200 .
1 HOT ROLLING PRACTICE – An Attempted Recollection Saral Dutta. B. Tech. (Hons.), I.I.T. Executive Director, ISP & RMD, SAIL (Retired) Rolling is a metal forming process in which metal stock is passed through a pair of rolls.
Mandrel Mill Process. In Mandrel Mill pipe manufacturing process, steel billet is heated to high temperature in the rotary furnace. A cylindrical hollow, which is also known as mother hollow, is produced with the help of a rotary piercer and set of roller arrangement that keeps the piercer at the center of the billet.
Strong resistance to heat, impact and wear is an essential quality for rolling-mill rolls which are used to roll out high-temperature steel ingots. Our technological expertise, through which we developed the world's first industrial multi-layer rolling-mill roll made by centrifugal casting, can realize rolls with such high added values.
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.
By strictly controlling the temperature and roll surface condition, stock sheets (or Hot-Rolled Steel Sheets and Coils plates) that are easy to process are produced with flawless surface condition and internal quality. All production . line processes, starting from feeding to the reheating furnace to the completion of coiling, are controlled by a
The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled 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.
Mill Roll Hardening Systems are becoming increasingly popular with the expanding development of cold mills which subject the rolls to high stresses.These systems are used to obtain rolls with high strength and resistance to surface wear. Induction heating has greatly contributed to improvements in hardening depth, with subsequent improvement in distribution of residual stresses.
Furnace rolls are an interesting set of rolls to build. They work in some of the harshest environments. They will typically see temperatures in excess of 500 degrees Fahrenheit for years at a time. Materials used are made to withstand this criteria, so they are also difficult to machine.
Rolling Mill The rolling mill is an 8? wide, four-speed, four-high, reversing Fenn mill that is currently equipped with 5? diameter, tool steel backup rolls. Typical use of this mill is to produce small quantities of experimental aluminum sheet for laboratory trials.
