| 제목 | Fabrication of Mineral Fiber from Slag by Melt-Spinning Method |
| 초록 | Mineral wool is a kind of material with good thermal and acoustic insulation properties, which mainly made up of mineral fibers. There are several fabrication methods to manufacture fiber, in which melt-spinning is a simple one. Mineral fiber is produced from solid rock, which is melted at around 1500℃, forming a highly viscous fluid. After melting, the molten rock flows under gravity action to form jet, which flows onto the system of high speed rotating wheels. Finally, mineral fiber is formed during the process of falling. Usually, a single fiber will be diameter of several-decade microns, with length of a few centimeters. In this study, we made mineral fiber by using blast furnace slag as raw material, which is the waste coming from steel and iron casting industry and is not friend to the environment. Furthermore, a four-disc upright spinning machine is used to spin the molten slag. The surface characteristics of the fibers mainly depend on the contact areas between the wheel and the molten slag, slag molten temperature and discs rotation speed. Particularly, the fibers fabricated in the wheel speed range from 1400 to 1500 rpm show the smoother surface, while the fibers will have irregular surface with heavy shots. |
