Abstract
A fiber and a fiber manufacturing method are provided, in which IGCC slag constitute a component of raw materials of the fiber. The fiber can be fabricated stably from the melt of the raw materials by the method in which the raw materials are preheated up to 1300° C. or higher; the raw materials are maintained at the same temperature for certain period of time; subsequently, the temperature of the raw materials are raised further to cause the melted materials are spun into fiber.
Claims10
A fiber comprising a slag discharged from integrated coal gasification combined cycle (IGCC slag) as a raw material.
A fiber manufacturing method, said method comprising of the following steps of:
- 1) heating a raw material comprising of IGCC slag up to 1300° C. or higher;
- 2) subsequently, maintaining the temperature of the raw material for a predetermined time;
- and
- 3) subsequently, raising the temperature of the raw material further to flow out through a forming hole thereby forming the raw material in the form of fiber.
