BS 3056:1973 is being revised as a series of Parts s
9、o that it will cover bricks for a wide range of specific applications and will be withdrawn on publication of the complete series of revised standards. This Part is identical with ISO 5019 “Refractory bricks Dimensions” Part 4:1984 “Dome bricks for electric arc furnace roofs”, published by the Inter
10、national Organization for Standardization (ISO). The series of brick sizes specified in this Part of BS 3056 are annulus-shaped for use in roofs of ringed dome construction, the sizes being derived from a basic 114 mm 76 mm cross section. The bricks are laid in the roof with their 114 mm dimension s
11、et radially and provision is made, by virtue of varying brick length, to accommodate three different roof thicknesses. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certa
12、in conventions are not identical with those used in British Standards; attention is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as decimal marker. Where the words “part of ISO 5019” ap
13、pear, referring to this standard, they should be read as “Part of BS 3056”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confe
14、r immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 4 and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table

16、 furnace roofs. 2 Dimensions The dimensions of refractory bricks for use in the domes of electric arc furnace roofs shall be as shown in the Table. The letter references used in the Table are illustrated in Figure 1. NOTEA commentary on the brick sizes specified is included in the Annex. 3 Brick des
17、ignations The bricks of the different dimensions shall be designated by the reference numbers shown in the Table. In these reference numbers: a) the first letter (H, J or K) indicates the brick length (roof thickness) (230 mm; 250 mm or 300 mm); b) the second letter (W, X, Y or Z) indicates the sphe
18、rical radius (2,7 m; 4,5 m; 6,3 m or 8,1 m); c) the digit in the third place (1, 2, 3 or 4) indicates the side arch taper (2 mm; 3 mm; 6 mm or 13 mm).

22、 Uncontrolled Copy, (c) BSI BS 3056-4:1985 BSI 08-19993 Annex A Commentary on the bricks selected for roof construction A.1 Ring construction is recommended, using bricks derived from a 114 mm 76 mm cross-section, to be laid in the roof with each 114 mm dimension set radially, i.e. in a plane passin
23、g through the vertical axis of the dome. A.2 Three roof thicknesses are recommended (i.e. 230 mm, 250 mm, and 300 mm). A.3 Bricks of four nominal spherical radii have been chosen (i.e. 2,7 m, 4,5 m, 6,3 m and 8,1 m) to cover roof diameters from 1,5 to 8 m and roof rise ratios of from 1 : 15 to 1 : 8
24、 as shown in Figure 2. There is no necessity to offer all four spherical radii for each roof thickness and six combinations of roof thickness and spherical radius have been selected, as shown in the Table. These combinations accommodate the higher roof rises now being used on most larger furnaces. B
25、rick dimensions have been rounded off to 0,5 mm and hence, for the various roof thicknesses, actual spherical radii may vary slightly from the nominal values quoted. A.4 For each of the six combinations, the Table includes the side arch tapers which are required in order to construct the individual
26、brick rings in the roof. Clearly, rings could be constructed from two selected tapers but four are included to give increased flexibility of selection and greater stability in the construction of large diameter roofs. A.5 An additional series of dimensions is being considered for adoption. Licensed
