Production process of wear-resistant slag-resistant iron runner castable
The invention discloses a production process of a wear-resistant slag-resistant iron runner castable, and relates to the field of iron runner castable, the production process comprises the following steps: grinding 30-50 parts by weight of brown fused alumina, 25-35 parts by weight of serpentine, 10-20 parts by weight of silicon carbide and 5-10 parts by weight of cement into powder, scattering the powder, spraying a nano-scale silicon nitride dispersion liquid on the scattered powder, and drying to obtain the wear-resistant slag-resistant iron runner castable. And adding 2-3 parts of a sintering aid, 2-3 parts of an antioxidant, 1-2 parts of an anti-explosion agent and 0.5-1 part of a water reducing agent into the dried powder to obtain the iron runner castable. According to the invention, after the main raw material is ground, the surface of the main raw material is sprayed with the nanoscale silicon nitride dispersion liquid to form the coating layer, and the silicon nitride has the characteristics of extremely high hardness and high temperature resistance and wraps the outside of the main raw material particles of the iron runner castable, so that the hardness of each powdery particle of the main raw material is enhanced; further, the abrasive resistance of the iron runner casting powder is comprehensively improved.
本发明公开了一种耐磨抗渣铁沟浇注料的生产工艺，涉及铁沟浇注料领域，包括按重量份计采用棕刚玉30‑50份、蛇纹石25‑35份、碳化硅10‑20份、水泥5‑10份研磨成粉料并使其飞散，对飞散的粉料喷涂纳米级氮化硅分散液，后将其烘干，在烘干后的粉料中加烧结助剂2‑3份、抗氧化剂2‑3份、防爆剂1‑2份、减水剂0.5‑1份得到铁沟浇注料。本发明通过对主要原料研磨后表面喷涂纳米级氮化硅分散液形成包覆层，根据氮化硅具有极高硬度和耐高温的特性，且包裹在铁沟浇注料主要原料颗粒外部，对主要原料每个粉状颗粒均起到硬度加强的作用，进而全方面提升铁沟浇注粉料的耐磨强度。
