Blast furnace environment-friendly carbonaceous binding agent, preparation method and blast furnace stemming
The invention discloses a blast furnace environment-friendly carbonaceous binding agent which is prepared from the following components in parts by mass: 2-25 parts of environment-friendly asphalt, 32-63 parts of shale tar, 3-20 parts of environment-friendly asphalt powder, 8-25 parts of a plasticizer and 5-29 parts of a carburant, and the plasticizer is prepared by mixing hydrogenated terphenyl, resin substances and high aromatic carbon environment-friendly oil through a specific process. The carburant is prepared by selecting petroleum coke and semicoke, grinding the petroleum coke and the semicoke to be less than or equal to 2000 meshes through grinding equipment, and co-melting the petroleum coke and the semicoke, the environment-friendly oil and the environment-friendly asphalt at 150-280 DEG C through shearing and stirring. The environment-friendly carbonaceous binding agent for the blast furnace can enhance the plasticity of stemming, is high in thermal stability and extremely low in benzopyrene content generated at high temperature, and can greatly improve the construction performance and the field working environment of the stemming.
本发明公开一种高炉环保碳质结合剂，各组分按如下质量份组成：环保沥青2‑25份，页岩焦油32‑63份，环保沥青粉3‑20份，增塑剂8‑25份，增碳剂5‑29份，其中增塑剂采用氢化三联苯、树脂类物质与高芳碳类的环保油通过特定工艺混合配制而成，增碳剂为选取石油焦与半焦通过研磨设备将其研磨至≤2000目在150℃‑280℃下通过剪切搅拌与环保油、环保沥青进行共熔从而制备得到。本发明的高炉环保碳质结合剂能够增强炮泥的可塑性，并且热稳定性强，高温产生的苯并芘含量极低，能够极大地改善炮泥的施工性能和现场工作环境。
