Foreword

This standard is a revision of YB/T 007-1991 "Aluminum carbon refractory products for continuous casting". Replace YB/T 007-1991 as of the date of implementation of this standard. The main changes in this standard compared with YB/T 007-1991 are as follows. --- Increase the preface; --- Remove the appendix; --- Increase and adjust the material grade; --- Adjusted the allowable deviation and appearance of the product. This standard is proposed and managed by the National Technical Committee for Refractory Standardization. This standard was drafted. Qingdao Shuangying Refractory Co., Ltd., Luoyang Nanyuan Refractory Co., Ltd., Wuxi Southern Refractory Limited. The main drafters of this standard. Dong Wenquan, Zheng Xuejie, Xu Wenxiang, Ping Zengfu, Lu Jimin. This standard replaces the previous release of the standard. YB/T 007-1991. Aluminum carbon refractory products for continuous casting

1 Scope

This standard specifies the classification, technical requirements, test methods, inspection rules, packaging, marking, transportation, and aluminum alloy carbon series refractory products for continuous casting. Storage and quality certificates, etc. This standard applies to aluminum carbon (composite zirconium carbon, magnesium carbon) refractory products for steel continuous casting.

C45, C40, C35, R50, R45, R40, R35, S60, S55, S45, Z70, Z65, Z55, M and other 14 brands. Among them, C stands for long nozzle (casting tube, temperature measuring sleeve), R stands for immersion nozzle (intermediate water inlet), S stands for stopper rod (plug head), Z generation The zirconium carbonaceous material in the composite part, and M represents the magnesium carbon in the composite part. 3.2 Tag example An immersion nozzle with an Al2O3 content (mass fraction) of 45% and a composite part ZrO2 content (mass fraction) of 65%, marked as R45-Z65. 3.3 Shape size The shape and size of the product are required by the user's drawings.

4 Technical requirements

4.1 Physical and chemical performance indicators of various materials should meet the requirements of Table 1. 4.2 The allowable deviation and appearance requirements of the product dimensions shall comply with the requirements of Table 2.
