卡拉干达钢铁公司开发出一种煤质高温粒化沥青,用作耐火材料热增塑剂,特别是高炉出铁(渣)口耐火材料热增塑剂。生产此种粒化沥青的原料是软化温度为65～75℃的沥青,沥青焦油及重沥青蒸馏物。在反应器中将沥青氧化到高温(软化温度135±5℃)。从反应器里将加热温度为360～385℃的高温沥青送入沥青接受器。然后用泵及管道将接受器中的沥青送入渣罐,从此罐再送至粒化用的工业试验装置。粒化沥青生产工艺是:使倾转渣罐中的沥青经受料槽到达粒化装置格栅,格栅上的孔保证熔化沥青像漏粉条那样流入结晶池。为了用脱水提升机收集沥青粒,在机尾配有三块挡板。沥青粒在机上完成结晶后由该机转运到平台。该设备的产量取决于送来粒化的沥青的
Karaganda Iron and Steel Company developed a coal-based high temperature pelletized asphalt used as a hot plasticizer for refractory materials, especially blast furnace slag (slag) refractory thermal plasticizer. Raw materials for the production of such granulated bitumen are bitumens, bitumen tar and heavy bitumen distillates with a softening temperature of 65-75 ° C. The bitumen is oxidized to high temperature (softening temperature 135 ± 5 ° C) in the reactor. From the reactor will be heated to a temperature of 360 ~ 385 ℃ bitumen asphalt into the receiver. The asphalt in the receiver is then pumped into the slag pot by means of a pump and pipe, from which it is sent to a commercial pilot plant for granulation. Granulated bitumen production process is: the pouring slag tank slag bitumen through the granulation device to reach the grid, the hole on the grill to ensure that the melted asphalt like leakage of powder into the crystal pool. In order to collect asphalt pellets with a dewatering elevator, there are three baffles at the tail end. The asphalt pellets are transported to the platform by the machine after they are crystallized on the machine. The output of this equipment depends on the size of the bitumen fed
