TEMPERATURE END POINTS OF PYROMETRIC CONES

Definition- Pyrometric Cone Equivalent (P.C.E.) - Supposing the case of Refractories, the amount of standard cone whose tip touches the supporting spot concurrently with a cone of the substance gets examined when tested as per the industrial standard method of Fire clay Bricks IS: 1528 Part-I 1980 of ISI.
Note: These expressions- “fusion point”, “deformation point”, “softening point” and “melting point”, have generally been used for Pyrometric Cone Equivalent (P.C.E.).

*Note: Pyrometric Cones do not provide precise temperature measurement. Where it is wished to construe P.C.E. values closed to the measured temperature. Above listed table can be referred because this table have been officially accepted by A.S.M.T., that is established on the works of fair child and peters, J. Amer. Cer. Soc. 9, 701-43, 1926. Correction in A.S.M.T. Cones from 12 to 37 (inclusive) were adopted in June, 1955, A.S.M.T. Standards 1955, 711.715 Heating rate: Cones 022 to 37 (inclusive), 150ºCent. per hour (270ºF per hour); Cones 38, 100º Cent. per hour (180ºF per hours). The aforesaid temperature ranges do not refer to slower of heating in commercialized firing and utilization of refractory substances. Above stated table/chart have been acquired by the Bureau Of Indian Standards.
