Definition of "Circored" |
WHAT A gas-based process developed by Lurgi Metallurgie in Germany to produce DRI or HBI. HOW The two-stage method yields fines with a 93% iron content. Iron ore fines pass first through a circulating fluidized-bed reactor, and subsequently through a bubbling fluidized-bed reactor.023943Circuit BreakerA circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset to resume normal operation.023944Circular ConnectorThe term Circular Connector applies to any electrical connector possessing multipin interconnects with cylindrical contact housings and circular contact interface geometries. Circular connectors are selected for ease of engagement and disengagement, their ability to conveniently house different types of contacts, their wide range of allowable contact voltages and currents, their ease of environmental sealing and their rugged mechanical performance.023945Circular PitchThe distance from a point on one gear tooth to the corresponding point on the next gear tooth, measured along the pitch circle.023946Clad MetalA composite metal containing two or three layers that have been bonded together. The bonding may have been accomplished by co rolling, welding, heavy chemical deposition or heavy electroplating.023947Clad SheetComposite sheet having on both surfaces (if on one side only, Clad One Side Sheet) a metallurgically bonded metal coating, the composition of which may or may not be the same as that of the core.023949Clamp MetersClamp meters are a very convenient testing instrument that permits current measurements on a live conductor without circuit interruption. When making current measurements with the ordinary multimeter, we need to cut wiring and connect the instrument to the circuit under test.023950ClarifiersClarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the liquid are called scum.023951Class 1 Hollow Extruded ProfileA hollow extruded profile, the void of which is round and 1 inch or more in diameter and whose weight is equally distributed on opposite sides of two or more equally spaced axes.023952Class 2 Hollow Extruded ProfileAny hollow extruded profile other than class 1, which does not exceed a 5 inch diameter circumscribing circle and has a single void of not less than 0.375 inch diameter or 0.110 square inch area.023953Class 3 Hollow Extruded ProfileAny hollow extruded profile other than Class 1 or Class 2.023954Class A SurfaceClass A surface is a term used in automotive design to describe a set of freeform surfaces of high efficiency and quality. Although, strictly, it is nothing more than saying the surfaces have curvature and tangency alignment - to ideal aesthetical reflection quality, many people interpret class A surfaces to have G2 curvature continuity to one another.023955Clean OutTo drive or force out: cleaned out the incompetent workers.023956Cleaning TankCleaning Tank after discharge, that is prior to recharging, is compulsory. Nobody wants residues of animal fat to turn up in a new load of beer.023957CleanlinessSteel cleanliness is an important factor of steel quality and the demand for cleaner steels increases every year. The so-called clean steel generally is the steel in which the content of impurity elements, such as phosphorus, sulphur, total oxygen, nitrogen, hydrogen and inclusions are very low. The improvement of steel cleanliness has therefore become a more and more important subject in the development of ferrous metallurgical technology, and also an important task for the iron and steel producers.023958ClearanceThe Clearance space or distance between moving objects or mechanical parts, or between a moving object and that which it passes through, over, under, etc.023959Clearance AngleThe angle between the rear surface of a cutting tool and the surface of the work at the point of contact.023960CleavageCleavage, in mineralogy, is the tendency of crystalline materials to split along definite crystallographic structural planes. These planes of relative weakness are a result of the regular locations of atoms and ions in the crystal, which create smooth repeating surfaces that are visible both in the microscope and to the naked eye.023961Cleavage FractureIn brittle fracture, no apparent plastic deformation takes place before fracture. In brittle crystalline materials, fracture can occur by cleavage as the result of tensile stress acting normal to crystallographic planes with low bonding. In amorphous solids, by contrast, the lack of a crystalline structure results in a conchoidal fracture, with cracks proceeding normal to the applied tension.023962Climb IllingA method of milling in which the work table moves in the same direction as the direction of rotation of the milling center. Sometimes called down cutting or down milling.023963ClipClip, a sheet of metal on an automobile extending from the firewall forward; also called the doghouse.023964Closed Center ValveA valve in which inlet and outlet ports are closed in the neutral position, stopping flow from pump.023965Closed CircuitAn electric circuit providing an uninterrupted, endless path for the flow of current.023966Closed Die ForgingForging is a metalworking process in which an impact device is used to deliver compressive force to areas of the metal in order to shape it. Forging was originally done manually with a hammer and anvil, however industrial forging machines now use hydraulics, compressed air, or other methods to drive mechanical hammers, or presses, into the surface.023967Cluster MillA rolling mill where each of the two working rolls of small diameter is supported by two or more back-up rolls.023969CMFCast Metals Federation.

CO2 lasers are also very cost effective and low maintenance.023981Co2 WeldingCO2 welding is a welding process that uses carbon dioxide to protect the weld pool from oxidisation during the welding process. It is also known as Metal Inert Gas, Manual Arc Gas Shielded, welding.CO2 is not the only gas used, it needs to be heavier than air to work.023982CoalescenceThe growth of particles of a dispersed phase by solution and reprecipitation, the growth of grains by absorption of adjacent undistorted grains.023983Coated MetalsDependable corrosion-free products made from Precision Steel's coated sheet and strip steels add up to substantial savings over plated-part costs. This is true whether or not the specification calls for coating of lead, tin, zinc or aluminum.023984CoatingA coating is a covering that is applied to the surface of an object, usually referred to as the substrate. The purpose of applying the coating may be decorative, functional, or both. The coating itself may be an all-over coating, completely covering the substrate, or it may only cover parts of the substrate. An example of all of these types of coating is a product label on many drinks bottles- one side has an all-over functional coating and the other side has one or more decorative coatings in an appropriate pattern to form the words and images.023985Coating Thickness GaugesCoating thickness gauges are used to measure dry film thickness. Dry film thickness is probably the most critical measurement in the coatings industry.

Ranging from 500 10,000 pounds. Anything 10,000 pounds and over get an IPM. A coil with a weight less than 5000 lbs. that does not meet customer specifications is called a salvage coil. These coils do not get an IPM number.023996Coil Line MarkingCompany offers a marking unit for dotted marking. The unit is designed for hot coil marking when a coil stops. This unit is normally employed when marking is assigned a short period of time. The time spent on the stop for marking may be considerably reduced when using a marking machine with dotted marking.023997Coil NumberOne of the items found on the identification tag that is attached to each coil when it is received from the steel mill.

It is used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells. Coiled tubing is often used to carry out operations similar to wirelining. The main benefits over wireline are the ability to pump chemicals through the coil and the ability to push it into the hole rather than relying on gravity. |
