Slag-bonding-free steel ladle lining brick for smelting aluminum killed steel
The invention discloses a slag-bonding-free steel ladle lining brick for smelting aluminum killed steel. Carbon nano tubes and carbon-containing resin powder are added into brick body raw materials. Specifically, the brick body is prepared from the following raw materials in parts by weight: 70 to 90 parts of fused magnesite, 2.5 to 4.0 parts of graphite, 10 to 15 parts of fused alumina-magnesia spinel, 2 to 4 parts of carbon nanotubes, 0.5 to 1 part of carbon-containing resin powder, 0.5 to 1.0 part of carbon black, 0.3 to 1.0 part of metallic aluminum, 0.3 to 1.0 part of metallic silicon, 0.1 to 0.5 part of boron carbide and 2.5 to 3.5 parts of thermosetting phenolic resin. Due to the fact that superfine materials, namely carbon nanotubes (nanoscale graphite carbon) and carbon-containing resin powder (CARBORESP) and a binding agent for refractory materials, are introduced into the raw materials, a lotus effect is formed on the surface of a prepared finished brick body, and by means of the characteristics that superfine graphite is large in wetting angle and not prone to being infiltrated by molten steel, the surface of the brick body is not prone to being wetted by molten steel. Therefore, the non-infiltrating performance of the steel ladle lining brick on the molten steel is enhanced, the phenomenon that the molten steel adheres to the steel ladle lining brick is reduced, and the service life of the steel ladle for smelting the aluminum killed steel is prolonged.
本发明公开了一种冶炼铝镇静钢用免粘渣钢包内衬砖，是在砖体原料中添加有碳纳米管和含碳树脂粉；具体的，砖体原料是由电熔镁砂70‑90份，石墨2.5‑4.0份，电熔铝镁尖晶石10‑15份，碳纳米管2‑4份，含碳树脂粉0.5‑1份，炭黑0.5‑1.0份，金属铝0.3‑1.0份，金属硅0.3‑1.0份，碳化硼0.1‑0.5份，热固性酚醛树脂2.5‑3.5份配制而成。由于在原料中引入了极细的材料‑‑碳纳米管（纳米级石墨碳）和含碳树脂粉（CARBORES®P，耐火材料用结合剂），使得在制备的成品砖体表面形成了“荷叶效应”‑‑利用超细石墨的湿润角大，不易被钢水浸润的特性，从而增强钢包内衬砖对钢水的不浸润性能，减少了钢水对钢包内衬砖的粘挂现象，提高了冶炼铝镇静钢用钢包的使用寿命。
