The coilbox arranged between the roughing stand and the finishing mill of a hot rolling mill forms coils of transfer bars, thus serving as both material and heat accumulator. During uncoiling, the former transfer bar tail runs into the finishing mill as transfer bar head. The coilbox is employed in new facilities and modernized plants.
same way as in conventional rolling up to the intermediate rolling mill. Here, after an acceptable section is produced, the slitting operation will start. Before deciding to implement the slit rolling method to an existing rolling mill it is essential to examine the suitability of this mill for the slit rolling technology.

Forged Rolls Forging is a process in which the cast ingot is heated in the furnace then material is hammered according to the customer''s required specifications. Thereafter heat treatment is done in annealing furnace.
The mill rolls take an initial thickness reduction in preparation for the finishing stands, Steel temperature must be monitored to meet parameters and prevent roll damage. Solutions: SPOT R100 or LSPHD 10.
Jun 19, 2017· Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.
Jun 09, 2017· A rolling mill is the place where the rolling of steel in carried out. It consists of one or more rolling stands along with some auxiliary equipment where auxiliary operations associated with the rolling of steels are performed. Rolling of steel in small and medium sized rolling mills is generally carried out in crosscountry rolling mills.
The work roll in chromium steel is the typical type of roll for the roughing stands of a hot strip mill. This application, very hard from a thermal point of view, needs rolls made in highstrength alloys that can withstand heavy rolling loads and wear at high temperature.
The steel roughing rolling mill stands are used to reduce the thickness of the steel while at the same time extending the overall length. Steel Roughing rolling mill stand is an important part of a work stand, roll bearing chock and roller adjustment device is installed on the frame.
Roughing rolling mill is a machine for rolling steel. Rough rolling is in the middle of heating and intermediate rolling mill, and its function is to process the heated slab by a roughing rolling mill into an intermediate blank that satisfies the finishing requirements .

At today''s demanding condition, maintaining stable operation of rolling mill is becoming difficult. MSD is a hydraulic cylinder installed to mill housing window and press a roll chock against the opposite side with constant force. MSD eliminates gap between roll chocks and mill housing, keep rolls in proper position and stabilize rolls.
AC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects. TMEIC designs and manufactures two types of AC solutions for this purpose. Salient pole synchronous motors that meet the high power and torque demands of a hot strip mill, as well as roughing and finishing stands.
Roughing/Reversing Mill. Application Overview. At the reversing mill, rolling speed, roll bite, and coolant flow may be optimized only with a precise realtime knowledge of metal temperature. The low and highly variable nongreybody emissivity character associated with this complex aluminum process dictates the use of the most sophisticated ...

The Tredegar rolling mill''s most famous work was the plates made for the ironclad ia. Power is transferred from a turbine or waterwheel to a set of gears, which drive a series of stands of rolls. Heated metal is elongated and shaped as it passes through each set of rolls. The rolls here, called roughing rolls, shape the metal first.
Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...
