Baking-free iron runner castable for hot jacket repair at iron falling point and use method of baking-free iron runner castable
The invention discloses a baking-free iron runner castable for hot jacket repair at a falling iron point and a use method of the baking-free iron runner castable. The castable aggregate comprises the following components in percentage by mass: 60-66% of brown aluminum oxide aggregate; 2-4% of wettable graphite; 0.16 to 0.2 percent of special carbon black; 10 to 14 percent of special aluminum oxide micro powder; 4 to 10 percent of silicon carbide with the particle size of 0.1 to 1mm; 6-10% of silicon carbide powder; 0.2 to 0.4 percent of boron carbide powder; 1 to 1.5 percent of metal silicon powder; 0.08 to 0.12 percent of explosion-proof fiber; 4-8% of compact emery powder and 5.4-5.8% of externally doped silica sol. On the construction site, the aluminum silicon carbide carbon slurry combined with the submicron SiO2 micro powder is smeared in the U-shaped mold, so that the time for molten iron to make contact with the castable is delayed, the good uniform baking effect on the castable is achieved, no maintenance, no demolding and no baking are innovatively achieved for hot jacket repair at the iron falling point, and the construction time is greatly shortened.
本发明公开了一种落铁点热套修用免烘烤铁沟浇注料及其使用方法。该浇注料骨粉料各组分按质量百分比计为：棕刚玉骨料60～66％；可润湿石墨2‑4％；特种炭黑0.16‑0.2％；特种氧化铝微粉10～14％；碳化硅0.1‑1mm:4～10％；碳化硅粉6～10％；碳化硼粉0.2～0.4％；金属硅粉1～1.5％；防爆纤维0.08～0.12％；致密刚玉粉4‑8％，外掺硅溶胶5.4～5.8％。施工现场，通过在U型模内涂抹亚微米SiO2微粉结合的铝碳化硅炭质泥浆，推迟了铁水接触浇注料的时间，对浇注料起到了很好的均匀烘烤作用，创新的实现了落铁点热套修无养护、无脱模、免烘烤，大幅度降低了施工时间。
