8、rd This Part of BS 5663 has been prepared under the direction of the Iron and Steel Standards Policy Committee. It is identical with ISO 8263:1992 Iron ore fines Method for presentation of the results of sintering tests, published by the International Organization for Standardization (ISO). The Tech
9、nical Committee has reviewed the provisions of ISO 4696 and ISO 7215, to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users

13、 can be conducted for several different purposes, for example, the assessment of the sintering behaviour of a particular iron ore fines, for production and quality control purposes at a sinter plant, or for research purposes concerned with the sintering process or sintering technology. From the resu
14、lts of these sintering tests, the sintering behaviour of an iron ore, or iron ore mix, is determined in terms of production rate, fuel consumption rate and sinter quality. The purpose of this International Standard is to establish the terminology and method for presentation of these results, for use
15、 when sintering test data is required to be exchanged between separate parties, such as will be the case where a particular iron ore fines has been assessed for commercial reasons, or where research or production results are to be published. 1 Scope This International Standard specifies a method for
16、 presentation of the results of sintering tests. It is applicable to all iron ore fines that are agglomerated by the sintering process. 2 Definitions For the purposes of this International Standard, the following definitions apply. 2.1 ore mix the blend of iron ores, and other iron bearing raw mater
17、ials, such as mill scale, basic oxygen steel making slag, dust, etc., used in the tests. It does not include return sintered fines, fluxes, coke or other solid fuel 2.2 sinter mix the mix of materials charged to the sintering test apparatus, which includes the ore mix, fluxes, coke or other fuel, an
18、d return sintered fines 2.3 mixing times the time, in minutes, taken for blending and granulating the various constituents of the sinter mix 2.4 moisture content of sinter mix the moisture content, as a percentage by mass, determined by drying the granulated sinter mix, as charged to the sintering t
19、est apparatus, at 105 C 5 C 2.5 moisture content for maximum permeability the moisture content of the granulated sinter mix at which maximum permeability is obtained 2.6 bulk density of sinter mix the mass per unit volume of the wet sinter mix as charged 2.7 hearth layer a layer of previously made a
20、nd sized sinter, or other iron ore material, which is placed on the grate before the sinter mix is charged 2.8 grate area the area of the grate of the sintering test apparatus 2.9 net bed height the height of the bed of sinter mix above the hearth layer, prior to the application of suction and ignit
21、ion 2.10 suction the air suction measured at the wind box or at the entrance of the main blower of the sintering test apparatus 2.11 ignition intensity the heat supplied per unit of grate area per unit time of ignition 2.12 ignition temperature the maximum temperature attained at or immediately abov
22、e the surface of the sinter bed during the ignition process 2.13 sintering time the time from the start of ignition until the exhaust gas temperature reaches a maximum 2.14 sinter cake the total mass of sinter produced, including the hearth layer and the material collected from the bottom of the win
23、d box 2.15 sinter handling treatment the tumbling and/or shatter treatment given to the sinter cake, obtained in a sinter pot to simulate the effects of handling and transportation in a sinter plant Licensed Copy: sheffieldun sheffieldun, na, Mon Dec 04 15:55:13 GMT+00:00 2006, Uncontrolled Copy, (c
