With the development of large-scale, automation and efficiency technology of high-pressure furnace in my country, the corresponding large-scale and commercial temperature-related technologies of hot blast furnaces have also become more mature, and the refractory materials for hot blast furnaces have also undergone major changes. The traditional high-aluminum bricks for hot blast furnaces will be replaced by low-frequency bricks for hot blast furnaces. To adapt to this change, the manufacturing material of the hot blast furnace is to provide the state with high-quality materials. At the same time, in order to improve the current market and serve the enterprises, the Y/T5016-1993 high-frequency bricks for hot blast furnaces are specially certified: This standard is different from the previous version as follows:
1. Add the physical and chemical standards for the production of low-frequency bricks in hot zone production: 2. Add the requirements for the allowable deviation and appearance of the hot blast furnace; 3. Add the requirements for the hot blast furnace process; 4. Add the requirements for the appearance of the hot blast furnace; 5. Add the requirements for the appearance of the hot blast furnace; 6. Add the requirements for the appearance of the hot blast furnace; 7. Add the requirements for the appearance of the hot blast furnace; 8. Add the requirements for the appearance of the hot blast furnace; 9. Add the requirements for the appearance of the hot blast furnace; 10. Add the requirements for the appearance of the hot blast furnace; 11. Add the requirements for the appearance of the hot blast furnace; 12. Add the requirements for the appearance of the hot blast furnace; 13. Add the requirements for the appearance of the hot blast furnace; 14. Add the requirements for the appearance of the hot blast furnace; 15. Add the requirements for the appearance of the hot blast furnace; 16. Add the requirements for the appearance of This standard is issued by the National Committee for Standardization of Fire Materials in Liangliu County, and the standard is jointly issued by: Geyang Fire Materials Co., Ltd., Henan Zhongzhou Refractory Material Co., Ltd., Duzhou Jihua Enterprise Co., Ltd., Shandong Iron and Steel Co., Ltd., and Shandong Zonghua Fire Materials Co., Ltd. The main authors of this standard are: Pu Wenzhong, Li Hongzai, and Zhang Yin Cheng, Hou Junjie, Mi Limin, Shi Yongji, Chen Yingqi: This standard was first issued in 19G3 as YR40%-1963, revised for the first time in 1982 as G2250-13%2. In 1987, it was revised for the second time as G2291-1987, and converted to YB/5C61995 in 1993. 1 Scope
