ASTM C416-1997(2002) Standard Classification of Silica Refractory Brick《硅土耐火砖的标准分类》.pdf

1、Designation: C 416 97 (Reapproved 2002)Standard Classification ofSilica Refractory Brick1This standard is issued under the fixed designation C 416; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number

2、 in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification is limited to silica brick meeting thefollowing requirements:Alumina (Al2O3) content of less than 1.50 %.Titania (TiO2)

3、content of less than 0.20 %.Iron oxide (FeO3) content of less than 2.50 %.Calcium oxide (CaO) content of less than 4.00 %.Average modulus of rupture of not less than 500 psi (3.45MPa).1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is ther

4、esponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

6、nd Technology3and other appropriate sources.3. Significance and Use3.1 The presence of certain impurities in silica brick tends tolower their refractoriness and service limits. This classificationpermits those familiar with refractories to predict the refracto-riness of silica brick from their alkal

7、i and alumina contents.4. Basis of Classification4.1 Flux Factor Silica brick are classified on the basis ofimpurities by the use of a “flux factor,” which is equal to thepercent of alumina plus twice the percent of total alkalies.4.2 Types:4.2.1 Type ASilica brick having a flux factor of 0.50 orles

8、s.4.2.2 Type BAll other silica brick falling within the scopeof this classification.5. Test Methods5.1 The properties listed in this classification shall bedetermined in accordance with the following ASTM methods:5.1.1 Modulus of RuptureTest Method C 133.5.1.2 Chemical AnalysisXRF and ICP.6. Retests

9、6.1 Because of variables resulting from sampling and thelack of satisfactory reproducibility in tests conducted bydifferent laboratories, the material may be resampled andretested when requested by either the manufacturer or thepurchaser. This may apply in instances when the first testresults do not

The final results to be used shall be the averageof at least two sets of results, each of which has been obtainedby following in detail the specified testing procedures.7.
