across the web times roll radius. This means the torque driving the unwind shaft must decrease at a linear ratio, relative to roll diameter, as an unwind roll decreases in size, through a machine run, to keep tension constant. Conversely, the torque driving the rewind shaft must increase at a linear ratio, relative to roll diameter, as a rewind

This manual offers an explanation of the variables that effect kiln operations and detailed procedures to assure minimum downtime. The manual also deals at length with narrow mechanical specialties, knowledge of which is necessary for a functional and practical understanding of rotary kiln operations

This Third Edition of the Design Manual has been prepared by The Steel Construction Institute as a deliverable of the RFCS Project - Valorisation Project – Structural design of cold worked austenitic stainless steel (contract RFS2-CT-2005-00036). It is a complete revision of the Second Edition, extending the scope to include cold worked

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

A matt grey is left on annealed mill products following descaling and pickling. Mechanical scale loosening roughens the surface. The terms'descaling', 'pic kling' and 'passivation' are often confused, but are distinct processes. It is important to be clear about the differences between these surface treatment processes as applied to stainless

a) Strip – A hot or cold rolled flat product and rolled approximately in rectangular cross section of thickness usually 12 mm and below with mill rolled or trimmed or sheared edges and in coil form. Wide strip – Hot/cold rolled strip of width normally equal or greater than 600 mm

Bar catcher: catches the bar from one roll stand, loops and feeds it into the next stand; Hot Strip Mills Coil slitter: sets up and operates a slitter line, slitting the coiled strip; Coiler: operates the equipment to coil or stack products being rolled on a mill; Transportation

This paper roll clamp with a capacity of 6,000 pounds is used as roll lifting equipment by a major paper mill. Back Up Roll and Chock Lifter This custom designed motorized back up roll and chock lifter was designed to simplify the process of removing or installing the backup roll assemblies into or out of a rolling mill at a major North

The Sheet Metal Rolling Machine works according to the principle of three point bending. The rotation of the driven rolls being utilized to feed the metal through the rolls by means of the frictional forces present between the surface of the rolls and sheet. No lubricant is used at its presence interference with the ability to grip

Experiment 5 - Cold Work, Recovery, Recrystallization and Grain Growth Objective To study the effects of cold working on the microstructure and mechanical properties of 70/30 Cartridge Brass. Background A small percentage of the energy expended in plastically deforming a material remains stored in the metal as an increase in internal energy

the hot rolled pickled and oil product through a series of progressive dies or rollers at room temperature. The effect of such work stretches the steel, which creates a permanent increase in the hardness, strength, and finish of the product. Cold finished steel is typically ready to be used for manufacturing finished goods, but in some

cold-rolled strip are thickness accuracy and flatness. We use an excellent automatic plate thickness controller and shape controller to manufacture cold-rolled strips exhibiting great shape with less thickness fluctuation

Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von K rm n's equation of equilibrium. Although applying strictly to the rolling of ideal plastic-rigid materials, these equations may be applied to the

EN Standards for Rolled Aluminium. The old BS1470 standard has been replaced by nine EN standards: EN485-1: Technical conditions for inspection and delivery EN485-2: Mechanical Properties EN485-3: Tolerances for HOT Rolled Material EN485-4: Tolerances for COLD Rolled material EN515: Temper Designations EN573-1: Numerical alloy designation system

ClarkDietrich U-Channel or Cold Rolled Channel (CRC), attached to the studs with clips or weld, are one of the most common bridging methods used to provide resistance to stud rotation and minor axis bending under wind and axial loads. 1-1/2 U-Channel is passed through the stud knockout and secured with ClarkDietrich's FastBridge Clip, SwiftClip™ (L-Series) or

Feb 13, 2003 Producer mills say they can get less than 15 I units of flatness coming off the cold mill. With a temper mill, they can get less than 10 I units. A roller leveler, a Strand Extensioner, or a tension leveler produces less than 5 I units, and maybe less than 1 I unit

S355 is a low carbon steel grade often used for application which require better mechanical properties than that of S275 grade. Commonly supplied in the as rolled condition it is used widely in the construction, manufacturing and offshore industries

Cold-rolled steel sheets are produced by cold rolling from hot-rolled coil, the typical manufacturing processes are described as Fig1. Pickling and Cold CSVC produces its cold rolled products by the combination line of PLTCM (abbreviated from Pickling and Tandem Cold-rolling Mill), and CAL (abbreviated from Continuous Annealing Line) respectively

Mechanical marking, cracking and spalling of work rolls is more prevalent in the latter finishing stands of hot mills, however, can occur on any stand of cold mill applications. Back up rolls from both hot and cold strip mills are also prone to mechanical marking. EXAMPLE Example 1 Large indentation at the barrel surface of a work roll

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill “sees” instantaneously unless some damping system such as a surge hopper is used

Mar 14, 2002 In its natural state, steel is not at all flat. In fact, a hot-rolled sheet coil generally reveals some or all symptoms of poor flatness (see Figure 1 ). For example, 72-inch-wide material with a 100,000-PSI yield strength can have a crossbow of 2 to 12 in., wavy edges, and excessive crown. These shape imperfections must be removed to produce a
