3 Definitions and symbols
Terms and definitions and symbols GB/T 10325 apply to this document defined.
4 size and shape classification
4.1 Classification
Brick according to chemical composition divided into low iron insulating firebrick high aluminum and high alumina insulating firebrick general categories (Table 1). Models D, L, G
Were low, aluminum, across the Pinyin initials; 170,160, 125, respectively, on behalf of the brick classification temperature (heating of permanent change
Test temperature) of the first three digits; 1.3,1.0, and 0.5, respectively, on behalf of the bulk density of brick; L represents the end of the bulk density of the grade
Less than GB/T 16763 of the predetermined value.
4.2 shape and size
Brick shape and size should be consistent with the provisions of GB/T 2992.1, but also demand side design and manufacturing.
