11、08-1999 Foreword This Part of BS 3056 has been prepared under the direction of the Refractory Products Standards Committee. It supersedes BS 3056:1973 which is withdrawn. The first edition of this standard, issued in 1959, specified sizes in imperial units with metric equivalents. In the second edit
12、ion, issued in 1973, metric units only were used and account was taken of the work in the International Organization for Standardization (ISO). The purpose of preparing this third edition is, first, to bring up to date the sizes specified and the size/material combinations, in the light of experienc
13、e since 1973; and secondly to divide the standard into Parts so that it may cover bricks for a wider range of applications than general purposes alone. This Part is concerned with multi-purpose bricks, which are those that are widely used in many different applications of refractories. These should
14、be considered by designers of refractory plant so that “specials” are only ordered after it has been ascertained that there is no brick size in this Part of BS 3056 that is suitable for the design. Nevertheless, some applications of refractory bricks have to be recognized as requiring brick sizes th
15、at are not included in this Part of BS 3056. Certain of these sizes for particular purposes are detailed in other Parts of BS 3056, for use in conjunction with selected multi-purpose bricks taken from this Part (it is possible, of course, that designers of refractory plant may find a use for these s
16、izes outside the sphere for which they have been developed). The remaining Parts of BS 3056 are: Part 2: Specification for bricks for use in glass-melting furnaces; Part 3: Specification for bricks for rotary cement kilns; Part 4: Specification for bricks for electric arc furnace roofs; Part 5: Spec
17、ification for bricks for blast furnace walls; Part 6: Specification for bricks for torpedo ladles1); Part 7: Specification for basic bricks for steel-making; Part 8: Specification for bricks for ladles1). Attention is drawn to the following British Standards which will be superseded by Parts 2 and 3
18、 of BS 3056, respectively: BS 5187, Standard sizes of silica refractories for use in glass melting furnaces. BS 4982, Standard sizes of refractory bricks for use in rotary cement kilns. BS 4982-1, Basic refractories. BS 4982-2, Fireclay and high alumina refractories. This Part of BS 3056 has been pr
19、epared taking into account the views of both manufacturers and users of multi-purpose refractory bricks; it is therefore felt that it should find universal acceptance in the many sectors of British industry in which refractory bricks are used. The committee has carried out an extensive industrial su
20、rvey which has been used as the basis for adopting the sizes specified in this Part of BS 3056. Wherever possible, 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
21、the UK have been included. A further requirement has been for simplicity of shape to permit economical production in mechanical brick press moulds. It is therefore intended that other shapes not included in this Part of BS 3056 will be referred to as special categories. 1) In preparation. Licensed C

23、e refractories, who can play the greatest part in achieving rationalization and economy in the use of shaped refractory products. Furnace designers are particularly asked to see whether a still larger proportion of multipurpose refractories can be selected from the range of sizes now offered. To ass
24、ist designers in this objective, appendices to this Part of BS 3056 provide formulae for the calculation of the number of tapered and circle refractory products required to form circles, and tables giving the combination of sizes to form circles of given diameters.
