A rolling mill comprises a working stand accommodating planetary (rolls) assemblies. Each assembly has an idle backup roll provided on an eccentric portion of the axle of that roll with the possibility of rotation, and a set of work rolls spaced along the periphery of the outer cylindrical surface of the backup roll, as well as a separator mounted on the backup roll axle, rotation …

Gear Ratio • You can think of gear ratio as a multiplier on speedand a divider on torque. • You can calculate the gear ratio by using the number of teeth of the "driving gear" (a.k.a. the inputgear) divided by the number of teeth of the "driven

Endless Hot Strip Rolling Process . In conventional hot strip production, slabs of thickness of about 250mm are heated in a furnace and are reduced to 30 to 60mm in thickness after passing through the roughing mill, and then further reducing it to within a range of 0.8 to 25.4mm by rolling in the finishing mill.
In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.
n-stand rolling mills. The model was used to simulate the plant in respect of the normal rolling mill practice, for the strip threading and tailing-out as well as the dynamic pro-gram change (DPC) for the technological functions such as reference generation, drives, roll gap posi-tioning and thickness and tension control.
(1) the following diagram specifies, a fuse must be connected between current and the machine. (2) the ground treminal of the machine must be grounded perfectly. (3) before cutting off current to the machine, don't open door to the electrical system. if …
The following 't'Wrk will describe the mill and its rolling process. The Planetary J!Jill• s action will be compared to conventional mills and some conclusions drawn to relate material properties to the planetary rolling process. The Planetary Mill is a medium output mill for rolling of steel strip.
James L. White, Kyonsuku Min, in Comprehensive Polymer Science and Supplements, 1989 9.3.2 Two-roll Mills. The two-roll mill was used in industrial operations of various types well into the dimmest past.It was, however, only with the 1836 patent of Chaffee 31 that roll mills began to be used in the polymer industry. Chaffee 32 sought to use roll mills and calenders in place of …

The rolling mill shown in Figure 4.47 is especially designed for the small workshop. The rolling mill frame consists of four round pillars which connect the upper and lower end plates together. The bearings in which the roller's arbors rotate can travel vertically on the polished guide columns. The rolls are 45 mm in diameter and 90 mm wide.
Ball Mill Working Principle. To be chosen according to the grinding material, material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body, when the ball mill cylinder rotation time, grinding body due to inertia and centrifugal force, the effects of friction, making it attached to the cylinder liner on the cylinder body away, when taken to the height of a ...
of 641.4 million tonnes with COG amounted to be more than 310 billion Nm3.5,6) The COG is currently used after its cleaning from tar, naphthalene, raw benzene, ammonia, and sulfur for heating of blast furnace stoves, ignition furnaces in sintering plant, heating furnace in rolling mills and elec-tric power generation in power plant.6,7) The ...
3: Four high rolling mill: It has a roll stand with four parallel rolls one above the other. The top and the bottom rolls rotate in opposite direction as do the two middle rolls. The two middle are smaller in size than the top and bottom rolls which are called backup rolls for providing the necessary rigidity to the smaller rolls. A four high ...
COG and natural gas are used for heating furnaces and electricity is consumed for mechanical equipment of rolling mill. Almost the whole electricity is utilized for huge engines of rollers. On the other hand, oxygen, argon and nitrogen gases are needed for shaving of coil and wirerods and hydraulic equipments in the rolling mills.
2 Principles and Applications of Metal Rolling (ii) Shape of the rolled product- flat, sections or hollow sections rolling. (iii) Direction of rolling- lengthwise, transverse, and skew rolling. (iv) Mode of rolling mill operation- continuous (unidirectional), and reverse rolling, where direction of rotation of rolls are reversed. When two rolls of equal diameter and with axis lying in same ...
These effects are compensated by the injection of COG. Thus a combined injection of oxygen and COG at the tuyere level increases the productivity of the blast furnace. Every 1 % of oxygen enrichment of hot blast improves the productivity by 2-0 % to 2.5 %. A typical schematic diagram of COG injection in blast furnace is given in Fig. 1.
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.
absorb approximately 95% of the BTX from the COG (AP-42, May 2008). The cleaned COG is rich in hydrogen and methane, having a nominal heating value of 500 BTU/scf, and is used throughout the facility as a fuel for firing the hot strip mill reheat furnaces, enriching blast furnace gas for coke oven and stove heating, and at boilerhouses No. 1 and 2.

After heating to the rolling temperature in a reheating furnace, these castings are hot-worked to the required products. Steel shapes, bars, and wire rods are worked on section and bar mills and wire-rod mills equipped with caliber rolls, plates are worked on reversing mills, and hot-rolled steel sheets are worked on hot strip mills.
