17、of dense shaped refractory products Part 3: Basic products containing from 7 % to 50 % residual carbon 1Scope This part of ISO 10081 specifies the classification and designation of dense shaped basic refractory products containing or more but less than residual carbon after coking. It is applicable
18、to products with or without antioxidant additives, with or without metal plates and reinforcement. NOTE 1ISO 10081-2 covers the classification of dense shaped basic products containing less than residual carbon. NOTE 2All bricks can be encased in metal plate and can be reinforced by means of an inte
19、rnal metal plate and/or mixed metal fibre. 2Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amend
