It supersedes BS5187:1975 which is withdrawn. BS3056:1973 has bee
12、n superseded by BS3056-1 covering multipurpose bricks. This Part of BS3056 is one of a series of new Parts intended to cover bricks for a wide range of specific applications. This Part is concerned with refractory bricks for glass-melting furnaces. It includes such sizes and shapes used within the g
13、lass industry that are already in BS3056-1 as well as those which are more specialized and for the glass industry alone. It therefore provides a complete document for the glass industry. This Part of BS3056 has been prepared taking into account the views of both manufacturers and users of refractory
14、 bricks for the glass industry; it is therefore felt that it should find universal acceptance in this sector of British industry. The committee has carried out an extensive industrial survey which has been used as the basis for adopting the sizes specified in this Part of BS3056. Wherever possible,
15、they have tried to adhere to guidelines for standardization based on this survey. Only sizes of bricks which are used in large quantities in industry and have been commonly accepted in the UK have been included. A further requirement has been for simplicity of shape to permit economical production i
16、n mechanical brick press moulds. It is therefore intended that other shapes not included in this Part of BS3056 will be referred to as special categories. With this in mind, furnace designers are urged to take full account of this Part of BS3056; it is the designer of a furnace, rather than the manu
17、facturer or purchaser of the refractories, who can play the greatest part in achieving rationalization and economy in the use of shaped refractory products. To assist designers, appendices to this Part of BS3056 provide formulae for the calculation of the number of tapered and circle refractory prod
18、ucts required to form circles, and tables giving the combination of sizes to form circles of given diameters. Nothing in this Part of BS3056, however, should be taken to mean that refractory bricks will not be available in other shapes, other sizes or other combinations of size and material. The mat
19、erials covered by this Part of BS3056 have been extended from BS5187, which dealt only with silica. Fireclay, high alumina, basic, zircon and insulating products are now included. In addition, to a limited extent, the use of fusion cast products, vacuum cast sillimanite and fused silica is covered.
20、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 confer immunity from legal obligations. Summary of pages This document comprises
21、a front cover, an inside front cover, pagesi andii, pages1 to26, an inside back cover 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 on the inside front cover.BS3056-2:1985 BSI 09-1999 1 1
22、Scope This Part of BS3056 specifies the sizes of the following shapes of refractory bricks for glass-melting furnaces: a) squares; b) splits; c) tiles; d) blocks; e) straights; f) side arch bricks; g) end arch bricks; h) crown bricks. NOTE 1Information is also given on the combinations of size and m
23、aterial/quality that may be expected to be available, on arch-brick formulae (seeAppendix A), on the combinations of sizes required to form circles of various diameters (seeAppendix B), and on information to be supplied by a purchaser (seeAppendix C). The volume of each standard size brick is given
24、as supplementary information, in Table 1 to Table 8. NOTE 2The tolerances on the sizes are not specified in this Part of BS3056, and may be the subject of agreement between manufacturer and purchaser. NOTE 3The titles of the publications referred to in this standard are listed on the inside back cov
25、er. 2 Nomenclature The names given to the various shapes of brick are as given in BS3446-1. 3 Sizes The sizes of refractory bricks for glass-melting furnaces shall be as given in Table 1 to Table 8. NOTE 1The symbols used in Table 1 to Table 8 are shown in the figure accompanying each table. These s
26、ymbols do not necessarily apply to any other tables or figures in this or any other standard. NOTE 2Information on the material or qualities in which each of the sizes may be expected to be available is given in Table 1 to Table 8. It is emphasized that this information is included only as general g
27、uidance for the benefit of a user of this Part of BS3056, and it is not to be interpreted as meaning that all of these combinations will be available, let alone available from any one supplier, or that no other combinations will be available. In the tables, the symbols in the column headings have th
28、e following significance: 4 Designation and statement of dimensions 4.1 The designations of the sizes, where available, shall be as given in Table 1 to Table 8. NOTEThese designations have been retained from the previous edition of BS3056 for reference purposes. They are unsuitable for the more comp
29、licated sizes and it is envisaged that they will be phased out or modified in a future revision. They should not be used for sole reference unless it is known that the recipients of the communication are conversant with them. It is recommended that, if there is any doubt whether the designations wil
30、l be understood, the dimensions should be stated, either in conjunction with or instead of the appropriate size designations. 4.2 The dimensions of a brick, where stated, shall be given in the order given in Table 1 to Table 8. F fireclay refractories (containing less than45% (m/m) alumina); HA high
31、 alumina refractories (containing45%(m/m) or more alumina); B basic refractories; S silica refractories; I fired insulating refractories; Z zircon refractories; F/S fused silica refractories; AZS fusion cast refractories; VC vacuum cast sillimanite refractories.BS3056-2:1985 2 BSI 09-1999 Table 1 Di
