由黄伯云院士领衔的专家组一致通过对湖南红宇耐磨新材料有限公司研发的“铬锰钨抗磨铸铁磨球”铸件新产品及相关技术的鉴定,认为该技术在行业内具有领先水平。矿山冶炼、钢铁水泥、火力发电等工业领域,需要用研磨机对矿石、煤炭等原材料进行粉碎。这一过程需要磨损、消耗大量的磨球和衬板。矿山冶炼中,这两大关键产品的消耗量几乎占到选矿成本的 The expert group headed by academician HuangBoYun unanimously passed the identification of new products and related technologies of “chrome manganese tungsten abrasion cast iron grinding ball” researched and developed by Hunan Hongyu Wear-resistant New Material Co., Ltd, which is regarded as the leader in the industry Level. Mine smelting, steel and cement, thermal power and other industrial areas, the need for grinding ore, coal and other raw materials for crushing. This process requires wear and consumes a large amount of ball and liner. Mining smelting, the consumption of these two key products account for almost the cost of dressing
