Standard is based on the YR/TG.7-199 high-alumina bricks for steelmaking. The public standard has the following differences from the previous version: Add - two unfired grades:
Product library number deleted Ding [1-65;
-Physical and chemical indicators are restored to estimate the system except for the refractoriness requirements. The standard will replace the YH/T5017-153 standard from the date of implementation. The standard will be issued by the National Refractory Material Standardization Technical Committee. The origin of this standard is: Zhengzhou Yihua Enterprise Group Co., Ltd., Luyang Refractory Material Co., Ltd., Sichuan Yangquan Hualing Time Exchange Co., Ltd.
