High-strength wear-resistant material for blast furnace water slag runner
According to the high-strength wear-resistant material for the blast furnace water granulated slag trough disclosed by the invention, through combination of several materials such as corundum with high hardness, composite micro powder, SiC whiskers and super-hard abrasives, the overall hardness and strength of the material are improved, the fluidity is improved, and the compactness and wear resistance are improved; the erosion resistance and the fatigue wear resistance of the material are improved; the superhard abrasive boron carbide, titanium boride particles, SiC whiskers and other materials are mutually connected in a staggered mode to form a crystal-particle-gel network structure, particles and fibers in a refractory material system are connected together, a particle-reinforced and fiber-reinforced double-reinforcement mechanism is formed, and the toughness and strength of the material are further improved; the high-strength wear-resistant material for the blast furnace water granulated slag trough has the characteristics of high strength, good toughness, wear resistance, corrosion resistance, erosion resistance and high interface bonding strength, can replace a traditional blast furnace water granulated slag trough material, greatly prolongs the service life of the water granulated slag trough, improves the productivity of a blast furnace, and has remarkable economic and social benefits.
本发明公开了一种用于高炉水渣沟的高强耐磨材料，通过硬度高的刚玉、复合微粉、SiC晶须和超硬磨料等几种材料组合，提高材料的整体硬度、强度，改善流动性，增加致密性、耐磨性；提高材料的抗冲蚀、疲劳磨损能力；超硬磨料碳化硼、硼化钛颗粒和SiC晶须等材料一起相互交错连接，形成晶体‑颗粒‑凝胶体网络结构，将耐火料体系中的颗粒、纤维联结起来，形成颗粒增强和纤维增强的双增强机制，进一步改善材料的韧性和强度；本发明用于高炉水渣沟的高强耐磨材料具有强度高、韧性好、耐磨、耐腐蚀、耐冲蚀、界面结合强度高的特点，可以取代传统的高炉水渣沟材料，大幅延长水渣沟的使用寿命，提高高炉产能，经济效益和社会效益显著。
